G. is inspecting n bank of transistors in n card translator used in completing long distance calls through the new telephone office in Salt Lake Transistors are located inside the tube-like Their size can bo determined from the Inset New device installed by telephone Company known as the It has been just ten years since the transistor was first demonstrated by Bell according to Axel A. manager of the Mountain States Telephone Company in This unusual no larger than an eraser on a heralded what has come to be called the electronic The transistor spanned in 10 years the development by the vacuum tube in 40 It can do almost everything an tube can do and do It cheaper over a longer period of The has no gives off no heat and operates as soon as it is turned It has no warm-up period like a vacuum It has an indefinite perhaps as long as a and uses only minute amounts of A flashlight battery will energize a transistor for hundreds of Although the transistor is only ten years old it has found its way into a wide variety of uses in hearing fuel injection portable TV toys and most of in the telephone One of the dramatic uses of transistors has been in America's space The transistors in the and the satellites relayed to earth the data sought by As the use of transistors has spread its cost has A transistor that would have cost in 1953 can be purchased today for In 1957 three were 30 million and it is expected this number will climb to a half-billion by and the price will continue to be and scientifically and in the telephone the transistor is fulfilling the promise made by the Bell Labs ten years ago that it would have significance in the field of Birch |
