Abstract

PURPOSE: To simplify constitution and operations and make maintenance easy by operating various ultrasonic pulse switches by two kinds of synchronizing lines.
CONSTITUTION: Respective ultrasonic pulse switches 1 thru N are respectively connected to synchronizing lines l1, l2 to connect discharging circuits to the capacitors of integrating circuits connected to constant voltage sources. The discharging circuit is operated by the output of a detection pulse amplifier circuit and only when the discharge voltage of the capacitor of the inteqrating circuit reaches the specified value, an oscillator is driven. Further the output of the detection pulse amplifier circuit is applied to the discharge circuit of the other ultrasonic pulse switch and the signal which controls the oscillation period of the oscillator is applied to the oscillator of the other switch.
