Disposal

The theme of this week is about the method of disposal of a television set.

 

Four item of a household appliance

Do you know four item of a household appliance? Four item of a household appliance is an “air-conditioner”, “television set (a cathode-ray tube, plasma, liquid crystal)”, ”a refrigerator (freezer) ”, and ”a washing machine and a clothes dryer.” About these four household appliances, a duty of taking over and recycling is imposed upon the manufacturer etc. And when used goods are discarded by the user, you will be asked for the burden of the expense. Three persons of a user, a store, and a maker need to assign and cooperate each other in a role, need to realize recycling of home electronics, and need to aim at the “recycling society” in which it is easy to live.

 

About the Home Appliances Recycling Law

It is a law for promoting effective use of resources, recycling a useful portion and material and decreasing the quantity of waste from the home electronics (an “air-conditioner”, “television set (a cathode-ray tube, plasma, liquid crystal)”, ”a refrigerator (freezer) ”, and ”a washing machine and a clothes dryer”) discharged from ordinary homes or an office.

 

The method of disposal of the television set in Tsukuba

Of course, the Home Appliances Recycling Law is applied in Tsukuba. Therefore, it does not be collected in a city. When you dispose of a television set, please request taking over from the store which purchased the product, and the store which carries out a change. If it is unknown the purchased store or it is troubled by disposal at the distant place, it takes over in a household appliance store at the city. Please ask directly a recycling-of-home-electronics recovery cooperation store about recycling cost. (It costs conveyance charge and recycling charge, and what is more, in the case of recovering from a house, in addition, it takes service charge, such as a recovery charge.) Moreover, when discarding the product in which the television tuner is built in with a personal computer monitor etc., it is the target of personal computer recycling. A recycling-of-home-electronics recovery cooperation store has a Nojima iias Tsukuba store, the K’s Denki Tsukuba Science City store, the Kojima university town store, etc.

 

Comment

By investigating about the disposal method of television set, it turned out that it is the concept of disposal of television set not “discarding” but “recycling”. Because I thought that household appliances, such as television set, were what will be discarded if it becomes impossible to use, I was a little surprised. Such as a concept of not “discarding” but “recycling” are important, and I thought that this concept is very good. When disposing, it also turned out that it takes money. I thought that I could get money reversely rather since recycling was the image of providing. However, when I consider carefully, I thought that it was unavoidable that money is taken since it takes conveyance charge. The idea of cooperating all together and paying is equal and nice.

Influence to society

The theme of this week is influence to society. Especially, I am going to talk about the influence to children.

While a child’s atrocious crime happens one after another, the interest how many influences television has had on a child’s action is high. About the television game having had various influences on a child, various indications from the usefulness to a bad influence is carried out. Until now, research has been done about the influence from broad viewpoints of psychology, sociology, physiology, etc. A possibility whether a television game would have a bad influence on a child’s development was often pointed out from before as a problems of a television game. It is especially worried about the bad influence to violence, social awkwardness, academic ability and mental faculties, eyesight, physical strength, etc. The television game bad influence theory has been repeatedly taken out with the cycle of about five years briskly. The peak of beginning of a bad influence theory is considered to be around Showa 63. Family Computer was sold in Showa 58 and it became the cause for a television game to spread through the home in Japan. However, we were not anxious about the bad influence for a while. But, after that, a family computer was spread explosively and a bad influence theory came to be seen gradually. At the time of “Dragon Quest incident” in Showa 63, the frenzy to child’s television game reached the peak, and the bad influence theory also reached the first peak simultaneously. The following peak is Heisei 5 after five years. This is related to the incident of Heisei 4, while a 14-year-old boy was doing the television game, an epileptic seizure was caused and he died. It not only says that a television game has a bad influence on epilepsy, but concern whether to have a bad influence also on various somatic aspects and also mental sides was briskly issued in journalism etc. The 3^rd peak is from Heisei 9 to Heisei 10, and makes an occasion frequent occurrence of the juvenile crime of those days. Existence of television game play was pointed out as one of causes. The 4^th peak is these days. The argument on a “game brain” which it has for television game play to check development of the prefrontal area which manages advanced information processing in man’s brain was issued in July, Heisei 14. Taking advantage of this, there is “video game bad influence theory” that a video game produces a quick-tempered child.

It cannot generally be said that the television game has actually had a bad influence. The television game may have had good influence. It may turn out that things must not be given up to the last. For example, probably, there is also a video game as an object for teaching materials. Don’t deny a television game completely. The television game is used in order to urge social awkwardness, especially adaptation of a child absent from school for a long time in recent years. Thus, the television game has had bad influence and good influence on society.

Utilizing Television

The theme of this week is about the utilizing television. There are many method of the utilizing television.　For example, there is not only a watching television program but also teleconference, television games and projecting the images taken by the camera. Next, I will describe each thing.

 

Teleconference

Teleconference is to connect two or more remote places by interactive telecommunication technology, and hold the meeting with a bidirectional picture and sound. It is also a kind of groupware. The advantage of a teleconference is that travel time and cost can be held down. It is not necessary to prepare the place of a meeting and to go to a conference hall place. It is only to connecting to television. Moreover, unlike an ordinary telephone, since the teleconference can see a mutual face and speak, it can aim at deep communication. However, there are a little problems here. It is known that eye contact is important in conversation. Although a partner’s face cannot be seen by ordinary telephone, since a face can be seen, the wrong impression may be given at a teleconference. Research which combines the picture of the right look with a stereo system in order to cope with this problem is advanced.

Television games

It is a kind of the computer game adapting electronic technology. In narrow sense, the computer game which uses a television set for home use as a display unit using a game machine for exclusive use is called television game. In broad sense, it is a computer game at large which uses a cathode-ray tube and a liquid crystal display for a display unit. And it is also called a video game. In a video game, in order not to limit a display to television here, a business-use game (arcade game) and a personal computer game are also contained. In addition, in the game industry of once Japan, the word of the “video game” was used synonymous with an arcade game in many cases. The latest main television game machines are Wii of Nintendo, PlayStation 3 of Sony Computer Entertainment, and Xbox 360 of Microsoft. The areas which have a large market of especially a scale at the present are Japan, North America (United States and Canada), and Europe (especially Britain), and these areas are the centers of a world market. In a Japanese market, there are the Mario series, the Dragon Quest series, the Final Fantasy series, Pocket-Monsters series, Zelda’s tradition series and other a large number in typical game software.

Projecting the images taken by the camera

The image taken by the digital camera and video camera can be projected on television, and can be seen. By projecting on television, a still picture and an animation can be seen in big screen rather than seeing with the camera itself. And by seeing by a big screen, it can see together with many persons. It is recommended projecting on television to see animation, such as a children’s exhibition and an athletic meet, with all families.

Price

This week theme is the television set price. I’m going to talk about this theme.

About the price fluctuation of a liquid crystal television set.

 

The sluggish sales of the liquid crystal television continue from “Perfect shift to ground digital broadcasting” (except for northeast 3 prefectures) in July, 2011. In 2012, a household appliance is deflation and the price of liquid crystal televisions fell. The price decline of main home electronics, such as a liquid crystal television, accelerates, and the Japanese home electronics maker is having a hard-fight.

Although consumers can buy a highly efficient new product at a low price, the situation where a home electronics maker and the store cannot take out more profits continues. According to the date in which Nikkei investigated the sales trend of 2300-company home electronics retailers across the country, the price of the household appliance model sold in the spring of 2012 fell 50 percent for the first time in half a year. And compared with five-year before, fall speed became quick from 10 to 30 percent. Thus, the reason the prices of home electronics, such as a liquid crystal television price is a technical development speed is early and the cheap and innovative product is sold for a short period of time.

The Japanese home electronics maker coped by the method of correcting the target of the volume of liquid crystal sales. It is also because the depression of the latest Japan continues and the real dealings price is low. The staffs of Yamada Denki said, “Consumers are familiar with household appliance deflation”, and it said, “There is a tendency to purchase after a price decline from a new product.”

The price of a liquid crystal television has had big influence on an affiliated manufacturer’s profit. Like the digital camera was pushed on the smart phone, the existing home electronics, such as a liquid crystal television and an audio instrument, must be pushed on a new product. Liquid crystal television makers, such as Panasonic, TOSHIBA, SHARP, and SONY, are coping with it by the method of correcting the target of the volume of liquid crystal television sales, in order to minimize the influence of a liquid crystal television price decline. For example, SONY reexamined the program for the year of the volume of television sales which will contain a liquid crystal television in August, 2012. And from the previous year, the program for the year of the volume of television sales was 21 percent decrease carried out, and was made into 15,500,000 sets. 2 million of these are less than the plan that beginning of the year.

Comment

 

This time, I investigated the price of the television, especially the price of the liquid crystal television, and felt the deflation of home electronics. We go to an electrical appliance shop, if it has 50,000 yen, we can buy good performance television in these days. I would like to buy it, after becoming cheap rather than I buy a new product. Moreover, I thought that progress of the latest technology was quick.

Mechanism

Screen of television – The three primary colors of light

Have you ever seen the screen of television nearby? If you see a screen of television, it turns out that the screen of television is made by gathering many small points. And the small point has only the three primary colors of red and a green and blue light. The television has been made by combining the point of 3 colors. By adjustment of these trichromatic combination and brightness, various colors are made, and it gathers and is visible as an image.

 

Photoelectric conversion

Light is changed into an electrical signal in order to send the image which was taken with the camera. An image is changed into an electric signal in order to send as an electric wave. An electric wave is flown from the antenna of a television station. Processing which the picture which was taken with the television camera changes into electricity from the light which is called “photoelectric conversion” within a camera is performed. Photoelectric conversion is the processing which changes the information on all the colors of an image into an electrical signal. A camera can be called equipment which changes a photographic subject’s color into digital date. The light from a photographic subject is decomposed into 3 colors of red, green and blue, the strength of each light is changed into an electrical signal, and it records as digital date. It seems that the quantity of red, green and blue paint is made into a numerical value, and a note of it is made. On the other hand, television can be called equipment for returning to a color from digital date. Red, green and blue light are given off and mixed as date, and an original color is reproduce and shown. It is like mixing the paint of the quantity as the numerical value currently written on the memo.

 

Structure of an animation

It is the same structure as flip book that the picture of television moves. As for an animation, a still image is displayed continuously. The image of the television is projecting many pictures into short time, in order to show more smoothly than a flip book. The number – They are 30 sheets in 1 second. It becomes such a smooth animation that there are many images displayed in 1 second. A flip book is one of the afterimage phenomena. An afterimage phenomenon is a phenomenon where the visible image remains in eyes for a while and which is in sight.

 

Scanning line – An image is projected.

In order to project one picture on an ordinary cathode-ray tube television screen, a picture to project is cut thinly horizontally, and it arranges the one line at a time in an order from a top, and is made a picture. This line is called “scanning line.” If the number of the scanning lines increases, an image is projected more beautiful. On ordinary television, there are 525 scanning lines and there are 1125 scanning lines in high-definition television.

Makers

Toshiba

TOSHIBA is selling a liquid crystal television called “REGZA.” The prime model of TOSHIBA is a liquid crystal television. TOSHIBA seems to be a match at a liquid crystal television. TOSHIBA is selling the liquid crystal television which carries a full-specifications Hi-Vision function. But it seems that there is nothing original about display, such as a liquid crystal and plasma. In fact, it seems that it excels in the ease of use of an operation system very much.

 

 

SHARP

SHARP is selling a liquid crystal television called “AQUOS.” The prime model of SHARP is a liquid crystal television. If it is called a liquid crystal television, it is SHARP. If it is called SHARP, it is a liquid crystal television. Thus, SHARP is very superior in the field of liquid crystal display. Needless to say, the function is also superior and compared with the television of SHARP and the television of the other company, the television of SHARP is more beautiful too.

 

 

Panasonic

Panasonic is selling a liquid crystal television and a plasma television called “VIERA.” The prime model of Panasonic is a plasma television. VIERA of Panasonic sold full-specifications Hi-Vision in the world for the first time. Since plasma is high contrast, high brilliance and high-intensity, no saying, if it is full Hi-Vision. But the price of a plasma television is high compared with a liquid crystal television.

 

 

HITACHI

HITACHI is selling a liquid crystal television and a plasma television called “Wooo.” The prime model of HITACHI is a plasma television. HITACHI acquired many patents about plasma and the technical capabilities of plasma are the top of the world. The display which projected a very wonderful image is manufactured by HITACHI.

 

 

SONY

SONY is selling a liquid crystal television and a plasma television called a “BRAVIA." The prime model of SONY is a liquid crystal television. Sony fell by a halfway strategy which sold a liquid crystal television or plasma television. But, the new brand “BRAVIA” is started, and it unifies into a liquid crystal (Sony panel), and Sony is trying to aim at a comeback. Since concentration is contained, it seems to be a very good product. The latest, Sony products hear the grumble of the person who purchased the cellular phone and personal computer so that they may often break down. I would like to expect what has good quality in the field of the television set.

 

 

Comment

It turned out that the model of latest television is mainly two, a liquid crystal television and plasma television. However, only a little, a liquid crystal television is superior to a plasma television. I surely think that the television in my house is also a liquid crystal television. I think that (my image) a liquid crystal television is for family to watch news or variety, and a plasma television is for rich to watch movies. It is because the liquid crystal television is cheaper and the plasma television is more expensive. Since the image of a plasma television is very beautiful, plasma television is my yearning. I want to buy a plasma television some day and I wish to hold a movie appreciation meeting.

Display

Cathode-ray tube television

 

The feature of a cathode-ray tube television is a low price. Compared with the thin shape television set of the same size also on television corresponding to digital Hi-Vision, price is about from half to one third. Old television was projecting the image on the screen called a “cathode-ray tube.” The display of a cathode-ray tube can be called in the abbreviation “CRT.” It is easy to watch screen of a cathode-ray tube compared with the liquid crystal television and plasma television which are displayed per dot. And since flattery nature is good to an animation, it is gentle to eyes. But since the cathode-ray tube is large compared with flat television set, it is difficult to make for a big screen (mean in volume). And the television of the cathode-ray tube was large and heavy compared with the present-day liquid crystal television, and carrying and installation were difficult.

 

 

Liquid crystal display

 

From the second half of 1990, the “liquid crystal television” and a “liquid crystal display” begin to appear. And after going into the 2000 year, the liquid crystal television became popular. A liquid crystal television uses the liquid crystal panel which has developed as a display of a personal computer for the display of television. At the time of release, dark in screen, eye is coarse, motion is blunt, tone is thin, if what moves at high speed is projected, an afterimage will be remained, if it sees from across, image quality fall off, viewing angle is narrow, it becomes immediately useless (it becomes dark) etc. – The system was not suited. Combined use of a cathode-ray tube and a liquid crystal display continued for a while. However, these faults are improved rapidly. Compared with a cathode-ray tube, thin and light, a place is not taken, low power consumption and big screen. – There is also a said good point and, now, it is becoming a typical system of television.

 

 

Plasma display

Newer television “plasma television” has appeared from 2003. From the first, plasma television is used as a display for indicating the personal computer screen etc. It has the advantage. It is thin and light like a liquid crystal television, but compared with a liquid crystal display, tone is good, projects what moves in display, an afterimage cannot be remained easily, and it is easy to see from across. However, it also has bad points. Power consumption is large, it is heavy, the fan is attached and it is noisy, very expensive, to make a big screen has a limit (since surface glass is not allowed distortion with a plank). – It is pushed a little by a liquid crystal television. Since improvement of a liquid crystal television also followed and image quality became good just like plasma television, the advantage of plasma television was lost gradually. Since plasma television has the advantage that cost seldom becomes high even if it enlarges it, on large-size television, it is often used. However, in small television and display, plasma television is already produced hardly.
