Abstract

PURPOSE:Through equipping the front end of effctive drive electrode over the area extending from the front end of leg up to the lengths of 0,4 to 0,6l(l shows a lngth from the front end of leg to the junction of leg. ), secondary vibration is prevented and a piezoelectric vibrator stably oscillating with frequenvcy of the basic vibration is obtained.
