High-power modulation. In an AM transmitter amplitude modulation of the carrier by introducing the modulating signal into the anode circuit of the final amplifying stage. The power of the modulating signal thus approximates to that at the transmitter output.  5, fiche 2, Anglais, - high%2Dpower%20modulation

Record number: 2, Textual support number: 2 CONT

Modulation is also identified as to level. High level modulation occurs when the modulating voltage is applied to the collector/plate circuit of the final power amplifier. With high level modulation, the final stage is operated class C and the preceding stages are also operated class C. The overall efficiency of such a transmitter is very high. A disadvantage of high level modulation is that comparatively high audio power is needed and several stages of voltage and power amplification may be required in the speech amplifier and modulator circuits.  4, fiche 2, Anglais, - high%2Dpower%20modulation

Semiconductive Thin Film Detector. Using the known principle that the adsorption and desorption of gases cause a change in electrical conductivity of semiconductors, Seiyama et al. developed a new chromatographic detector for gaseous components.... The current, depending upon the resistance of the film, is converted to voltage by the variable resistance, which is fed without amplification to a recorder. Resistance also adjusts the input voltage of the recorder at desired sensitivity. Using zinc oxide as an example of a typical film material, the conductivity of its film maintains a fixed value when the nitrogen carrier gas is passed at a constant flow rate throught the borosilicate glass tube. When a small amount of another gas or vapor is added to the carrier gas, its conductivity is changed.  1, fiche 7, Anglais, - semiconductive%20thin%20film%20detector
