PROBLEM TO BE SOLVED: To provide a large capacity ultrasonic composite vibrator which has rigidity as a composite vibrating body for various kinds of powerful ultrasonic waves. SOLUTION: The n sets of BLTs (1, 1', 2, 2',...n, n') having the same properties are arranged at the outer circumference part of a disk vibration body 4 oppositely to each other and at regular intervals. Each opposite BLT is driven in an opposite phase mode. A phase between adjacent BLTs of each set is driven in a vibration mode to shift the phase byπ/n. A vibration rod joined at the center of the disk vibration body is excited by a composite vibration output having a vibration capacity of n times of one set of BLT induced at the center of the disk vibration body 4. A plurality of vibrators are joined to further increase the vibration capacity. COPYRIGHT: (C)2004,JPO
