Abstract
PURPOSE: To make it possible to periodically dive an ultrasonic vibrator transducer always at a resonance frequency by driving the ultrasonic vibrator transducer by the oscillation signal of such a sweep generator of which the sweep range includes the fluctuation range of the resonance frequency of the ultrasonic vibrator transducer. CONSTITUTION: The frequency of the output signal of the sweep means consisting of a saw tooth wave oscillator 11 and a voltage control oscillator 12 is repetitively changed within the prescribed range inclusive of the resonance frequency of the ultrasonic vibrator transducer 14. The ultrasonic vibrator transducer 14 is driven by the output signal of the sweep means in an electric power amplifier 13. Consequently, even if the resonance frequency of the ultrasonic vibrator transducer is changed by the fluctuation of load, etc., the ultrasonic vibrator transducer may be periodically driven always at the resonance frequency.
