Abstract: PURPOSE:To perform a small-sized, light-weight and inexpensive rectifier by commonly using diodes and reactors for a main circuit and an auxiliary power source, thereby simplifying the construction of the auxiliary power source. CONSTITUTION:In a main circuit, an AC is rectified by a mixture bridge rectifier of diodes D1P, D2P and thyristors SCRIN, SCR2N, and smoothed by a reactor L and a capacitor C1 to obtain a DC voltage. In an auxiliary power source, AC input terminals U, V are connected through a capacitor C11 and diodes D11N, D12N with DC positive line of the main circuit to obtain a DC voltage across a capacitor C11. The capacitor C1 of the main circuit side is controlled at the DC voltage by the control of the thyristors SCR1N, SCR2N. The capacitor C11 of the power source is charged by a DC voltage full-wave rectified by diodes D1P, D2P, D11N, D12N and a reactor L1.

Title: Signal conversion circuit
Inventor: HASHIMOTO MASARU
IPC: H03F3/34
Filed: 1978-09-04
Abstract: PURPOSE:To attain a convertor circuit obtainable a current signal of an enough large gain by only adding a Tr of little difference of area ratio with a transistor Tr required for signal conversion. CONSTITUTION:Tr Q1, Q2 operate in the differential, and the collector of Q3 or Q8 performs output. The almost part of the collector current of Q1, Q2 is what runs as the collector current of Q4-Q7, and when Q4-Q7 are all in a same shape, the collector current of Q4, Q5 are equal, and also equal to those of Q6, Q7. Therefore, from the fact the collector current of Q1 and that of Q2 become equal, a small changed part of the collector current of Q1, Q2 in a differential type all becomes a changed part of the base current between Q4, Q5 and Q6, Q7, and change of these collector currents come to large. Therefore, by taking out the current equal to the collector currents of Q4, Q5 and Q6, Q7 from the collectors of Q3, Q8 respectively, it is possible to take out very large change of current as output with small change of input.
