Abstract

PURPOSE: To make possible automatic adjustment so as to provide resonance frequency automatically at the production or exchanging by subjecting ultrasonic vibrators which oscillate ultrasonic waves for the purpose of detecting objects to feedback controlling so that they oscillate at the resonance frequency at all times.
