Title: Thyristor scherbius system
Inventor: HAYAKAWA ISAMU
IPC: H02P23/16
Filed: 1979-04-02
Abstract: PURPOSE:To prevent commutation failure under instantaneous power clutter, by using the forward power rectifier diode of a Scherbius unit and a thyristor unit to absorb an abnormal voltage which occurs across the secondary side of an induction motor under power failure.

Title: Variable phase shifter
Inventor: TAKAHASHI MASARU
IPC: H03H7/20
Filed: 1990-02-20
Abstract: PURPOSE:To vary the phase largely by providing an optional phase shift to a high frequency signal by a variable resistor and a variable capacitance equivalently by the control of an applied voltage. CONSTITUTION:A bias power supply 4 of a field effect transistor(FET) 5 is set properly and the FET 5 acts like a variable resistor by varying the voltage of a phase control power supply 9 and a diode 8 acts like a variable capacitor whose junction capacitance varied with a voltage change of the phase control power supply 9. Thus, the FET 5 is regarded as an equivalent resistor (R) and the diode 8 is regarded as an equivalent capacitor (C) and the resistor R and the capacitor C are both varied with the increase/decrease in the voltage of the phase control voltage 9. Thus, a larger phase change than the change by the C in a conventional phase shifter is obtained.
