Western Electric Co., Inc. was an American electrical engineering and manufacturing company that operated from 1869 to 1996. A subsidiary of the AT&T Corporation for most of its lifespan, Western Electric was the primary manufacturer, supplier, and purchasing agent for all telephone equipment for the Bell System from 1881 until 1984, when the Bell System was dismantled.
The common base current gain (or α) of a point-contact transistor is usually around 2 to 3, [4] whereas α of bipolar junction transistor (BJT) cannot exceed 1. The common emitter current gain (or β) of a point-contact transistor does not usually exceed 1, [4] whereas β of a BJT is typically between 20 and 200. Negative differential ...
Western Electric became the manufacturing arm of the Bell System. In 1951, just four years after the invention of the transistor by Bell Laboratories, the Allentown Plant was opened to manufacture the first transistors. [2] [3] Jack Morton was assigned to develop transistors for manufacture. He had been responsible for inventing and providing ...
Bell Labs [b] is an American industrial research and development (R&D) company, currently operating as a subsidiary of Finnish technology company Nokia.With a long history, Bell Labs is credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages ...
The world's first commercial transistor production line was at the Western Electric plant on Union Boulevard in Allentown, Pennsylvania. Production began on Oct. 1, 1951 with the point contact germanium transistor.
The Hawthorne Works was a large factory complex of the Western Electric Company in Cicero, Illinois. In addition to industrial plants, several on-site community amenities were provided to workers. Named for the original name of what became Cicero, Hawthorne, it opened in 1905 and operated until 1983.
CPU logic was implemented using discrete diode–transistor logic. One hard plastic card commonly held the components necessary to implement, for example, two gates or a flipflop. A great deal of logic was given over to diagnostic circuitry. CPU diagnostics could be run that would attempt to identify failing card(s).
The first hot-cathode CRT, the Western Electric 224-B, had a standard four-pin bayonet base, and the bayonet pin was a live connection. (Five effective pins: It was an electrostatic-deflection gas-focused type, with a diode gun and single-ended deflection.
