71Computed tomography — tomos (slice) and graphein (to write).Computed tomography was originally known as the EMI scan as it was developed at a research branch of EMI, a company best known today for its music and recording business. It was later known as computed axial… …
72Glowing plate — When a vacuum tube circuit malfunctions and draws excessive current, the anode ( plate ) may overheat, sometimes causing a visible red or orange glow. In consumer electronics, this is universally indicative that the tube is experiencing an… …
73diode — /duy ohd/, n. Electronics. a device, as a two element electron tube or a semiconductor, through which current can pass freely in only one direction. [1919; DI 1 + ODE2] * * * Electronic device that has two electrodes (anode and cathode) and that… …
74Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… …
75Battery (vacuum tube) — In electronics, vacuum tubes were traditionally powered by batteries. Each battery had a different designation depending on which vacuum tube element it was associated with.Initially, the only such device was a diode with only a filament… …
76semiconductor device — ▪ electronics Introduction electronic circuit component made from a material that is neither a good conductor nor a good insulator (hence semiconductor). Such devices have found wide applications because of their compactness, reliability,… …
77Gunn diode — A Gunn diode, also known as a transferred electron device (TED), is a form of diode used in high frequency electronics. It is somewhat unusual in that it consists only of N doped semiconductor material, whereas most diodes consist of both P and N …
78TEA laser — The CO2 TEA laser was invented in the late 1960s by Dr Jacques Beaulieu working at the Defence Research Establishment, Valcartier, in Quebec, Canada. The development was kept secret until 1970 when brief details were published.C K N Patel,… …
79Nickel–metal hydride battery — NiMH redirects here. For other uses, see NIMH (disambiguation). Nickel–metal hydride battery Modern, high capacity NiMH rechargeable cells specific energy 60–120 W·h/kg[1] …
80Electrometer — An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. There are many different types, ranging from historical hand made mechanical instruments to high precision electronic devices. Modern… …
