BONE VIBRATOR AND MANUFACTURING METHOD THEREOF HAVING ELECTRODE CONNECTING PART WHICH INCREASES RELIABILITY BY SIMPLIFYING MANUFACTURING PROCESS AND ULTRASONIC MOTOR EQUIPPED WITH THAT

摘要

PURPOSE: By forming the electrode connecting part on the outer circumference of the first and the second piezoelectric the ultrasonic motor including that with the bone vibrator and manufacturing method thereof selectively interlinks the electrodes of the first and the second piezoelectric.;CONSTITUTION: A bone vibrator of the ultrasonic motor comprises the piezoelectric(21) which vibrates the oscillating element by being created the progressive wave in the logic high of voltage and oscillating element(20a). In the + pole and - pole is piezoelectric, it is by turns polarized. The first piezoelectric layer is attached to the oscillating element. The second piezoelectric layer is attached to the first piezoelectric layer. The electrode portion comprises the first side of the first and the second piezoelectric layer and the first side and the opposite surface a plurality of electrodes which is formed in the second side.;COPYRIGHT KIPO 2010
