It is well known that the quick development of electronics began with invention of transistors. They replaced electronic tubes due to their numerous advantages. One of the main advantages of the transistors in comparison with the vacuum tube is absence of filament power loss. One of the principal causes of damages in electronic circuitry is high temperature. The heat causes breakdown of tubes and other circuit elements that are very sensitive to this influence. The transistor, on the other hand, does not heat its surroundings.
Another advantage of the transistor is its long life. The life of the average transistor is more than ten thousand operating hours. Because of its long lifetime and raggedness, the transistor is very reliable and has much better efficiency in professional equipment.

As we know, transistors replace electronic tubes due to their numerous advantages. One of the advantages of the transistor is its small dimensions. Because of their small size the absence of heating and other properties, transistors make it possible to produce compact, small-dimensioned electronic devices which consume very little power.
In conclusion it is important to note that transistors revolutionized many fields of technology. They are successfully used for direct transformation of heat energy by means of thermal elements. They are also used to convert radiant energy into electricity with the help of photocells or solar batteries. Light sources and lasers are built on the basis of transistors. They find wide application in computers, automatic devices, aviation, communication, etc.
| 10. Konosuke Matshushita is the Founder of Panasonic. When Konosuke Matsushita began working for himself, in 1918, he had almost nothing: no money, no real formal education, no connections. Yet, his small firm flourished under the guiding hand of a clever, wise, and inspired entrepreneur. Konosuke Matsushita began the Panasonic’s journey by inventing a two-socket light fixture. This very important, yet elegantly simple, breakthrough led to what is now one of the world's largest electronics companies. In the late 1980s, Matsushita’s revenues hit a whopping $42 billion. |
“The main purpose of production is to manufacture items of good quality for daily use in abundant supply, thereby enhancing and improving the life for everyone and it is this goal that I am dedicated. Achieving this mission is the ultimate purpose of Matsushita Electric, and we will devote untiring energy to realize this goal.” – Konosuke Matsushita
