Semiconductor

1. This, in turn, will be limited by the physical and electrical characteristics of the vacuum tube as well as the semiconductor. (Web site)

Semiconductor Device

1. A semiconductor device can perform the function of a vacuum tube having hundreds of times its volume. (Web site)

Main Component

1. The main component of such a device is the Image Intensifier - basically a vacuum tube.

Electronic Devices

1. It quickly replaced the vacuum tube in many electronic devices. (Web site)

Semiconductor Diodes

1. The most familiar diodes are vacuum tube s and semiconductor diodes. (Web site)

Electronic

1. Therefore, early electronic (vacuum tube based) computers were generally faster but less reliable than electromechanical (relay based) computers. (Web site)

Electronics

1. Electronics is often considered to have begun when Lee De Forest invented the vacuum tube in 1907.

Electric Current

1. In 1840, British scientist Warren de la Rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it. (Web site)

Transistor

1. Quantum computers could one day replace silicon chips, just like the transistor once replaced the vacuum tube.
2. The term emitter also has specialized meanings in transistor and vacuum tube technology. (Web site)

Transistors

1. Having replaced the vacuum tube, transistors are the basis of much modern electronic technology, including the microprocessor. (Web site)
2. The expression became prevalent in the 1950s and the 1960s, during the transition from vacuum tube technology to semiconductor diodes and transistors. (Web site)

Television Set

1. A cathode ray tube is a vacuum tube that is used as a picture tube in a television set. (Web site)

Disconnect

1. Disconnect the fuel tube and vacuum tube at the carburetor. (Web site)

Diodes

1. Like light bulbs, vacuum tube diodes have a filament through which current is passed, heating the filament. (Web site)
2. Before the development of silicon semiconductor rectifiers, vacuum tube diodes and copper(I) oxide or selenium rectifier stacks were used. (Web site)
3. Early diodes included “cat’s whisker” crystals and vacuum tube devices (called thermionic valves in British English).

Xenon

1. Xenon in a vacuum tube produces a beautiful blue glow when excited by an electrical discharge. (Web site)

Electron

1. The (rest) mass of an electron is 511 keV. So the frequency correction is 1% for a magnetic vacuum tube with a 5.11 kV direct current accelerating voltage. (Web site)

Electrons

1. Any vacuum tube which operates using a focused beam of electrons (" cathode rays ") is known as a cathode ray tube.
2. In a vacuum tube, on the other hand, the charge carriers (electrons) are emitted by thermionic emission from a cathode heated by a wire filament. (Web site)
3. A simple experiment with electrons in a vacuum tube can convince you that mass increases in this way.

Oscillators

1. Good examples of analog circuits include vacuum tube and transistor amplifiers, operational amplifiers and oscillators.

Anode

1. The negative pole or electrode of an electrolytic cell, vacuum tube, etc., where electrons enter (current leaves) the system; the opposite of an anode.

Cathode

1. Electron Stream: Electrons moving from the cathode to the anode across a potential difference in a low-pressure gas tube or a vacuum tube. (Web site)
2. Photocell: A vacuum tube in which electric current flows when light strikes the photosensitive (or light sensitive) cathode. (Web site)
3. This target is bombarded by an electron beam emitted from the cathode of the vacuum tube under a high beam-accelerating potential. (Web site)

Vacuum Tube

1. Heinrich Hertz (1857-1894) a German physicist, laid the ground work for the vacuum tube. (Web site)
2. X-rays are generated by an X-ray tube, a vacuum tube that uses a high voltage to accelerate the electrons released by a hot cathode to a high velocity. (Web site)
3. A cathode heater is a coil or filament used to heat the cathode in a vacuum tube or cathode ray tube.
