Abstract
PURPOSE:To vary and set the oscillation frequency of an oscillator and to hold the set amplitude constant, by controlling the conduction period of a switching element by driving the oscillator by using the switching elememt. CONSTITUTION:If a current flows through the driving coil 3 of an oscillation part 1 owing to a shock, noise, etc., in feeding electric power, an oscillator 2 oscillates and its oscillation is detected by an oscillation detecting coil 5, increasing its phase current again through amplifying circuits 11 and 14. In this case, the output amplitude of the oscillation part 1 is less than a set value, and consequently the outpt C of a comparing amplifier 8 increases above a saw-tooth wave voltage D. Then, a comparator 13 generates no output and the circuit 14 operates as a mere amplifying circuit. As the oscillation amplitude increases, the output amplitude of the oscillation part 1 increases a comparator B controls the circuit 14 with an output E to generate the period when an output F is a (0).
