H. Eccles in Electrician 18 Apr. 475/2 It seems very natural to call a vacuous space containing three electrodes a ‘tri-electrode’, or, for short, a triode. 1919 Nature 30 Oct. 178/2 The internal action of a triode valve. 1923 Mod. Wireless June 304/2 The amplifier used consisted of a single Western Electric triode. 1926 R. W. Hutchinson First Course Wireless viii. 140 The modern valve used in wireless and known as the triode consists of a tungsten filament and a plate, with a wire grid between them, the three being quite separate from each other. 1943 C. L. Boltz Basic Radio x. 155 The thing which is most striking about the triode is the effect of grid voltage on the anode current. 1948 Physical Rev. 74 230/1 (heading) The transistor, a semi-conductor triode. 1962 D. F. Shaw Introd. Electronics xi. 220 One of the most important uses of the triode valve is for the amplification of a voltage. 1962 J. H. Simpson & R. S. Richards Physical Princ. Junction Transistors viii. 191 The second type of avalanching triode..is obtained by connecting a base lead to either the n1 or p2 sections of the diode in Fig. 8.22. 1974 A. Van der Ziel Introd. Electronics ix. 216 The vacuum triode is hardly ever used as a small-signal amplifier except at high temperatures, but it is still the only way to develop very large powers. < as lemmas |
