Abstract

1,050,192. Converting. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Feb. 27, 1964 [March 2, 1963], No. 8241/64. Heading H2F. [Also in Divisions G1 and G3] A constant voltage source for self-balancing instruments comprises a transistor oscillator 10 which operates at a frequency substantially higher than commercial power frequency and which is supplied over a rectifier 11 from a source e of commercial frequency, the output from the oscillator 10 being rectified and stabilized by a circuit 1 including Zener diodes 3, 4.
