Define Vacuum diode. Vacuum diode synonyms, Vacuum diode pronunciation, Vacuum diode translation, English dictionary definition of Vacuum diode. n. An electron tube from which all or most of the gas has been removed, permitting electrons to move with low
vacuum tube An electron tube from which all air has been removed so that the moving electrons don't collide with any gas particles and can move more efficiently from one electrode to the other. Cathode-ray tubes, which include television picture tubes and other video display tubes, are the ...
Vacuum tube 真空管/电子管 真空管/电子管的发明 1904, John Ambrose Fleming invented the two-electrode vacuum-tube rectifier, which he called the oscillation valve. It was also called a thermionic valve, vacuum diode, kenotron, thermionic tube, or Fleming valve. 1906, Lee de Forest invented the...
include Eico, Heathkit, Mercury, B&K, and Sencore. There are a few problems using any emission tester. The emission test basically connects all of the elements of the tube together, except the cathode, and tests it as a diode for cathode emission. The meter scale is most commonly labeled ...

The emission test basically connects all of the elements of the tube together, except the cathode, and tests it as a diode for cathode emission. The meter scale is most commonly labeled "Bad-?-Good". Most tubes other than diodes depend on the control of the electron flow rather than the...
X-ray Sealed Vacuum Diode Tube High Voltage Resistant Metallized Ceramic Housing Production Process We use 95% alumina ceramics to make ceramic tubes by hot pressing process, and then use the Mo-Mn method to metallize the ceramic tubes in a hydrogen brazing fu...
A vacuum tube, electron tube (in North America), or thermionic valve (elsewhere, especially in Britain) and Röhre in German (Adjective/Plural? Röhren as in Röhrenradio = Valve Radio), usually simply called “tube” or “valve”, is a device that uses wires, grids and plates to ...
