Actuator

Abstract

Abstract PURPOSE:To accelerate the response speed and to improve the accuracy of an actuator by laminating piezoelectric effect ceramics, amplifying the distortions of the ceramics, and removing them. CONSTITUTION:The first and second drivers 7, 8 are composed by laminating piezoelectric ceramics. When the first driver 7 is energized, an output shaft 25 is pushed by the distortion. The second driver 8 is rotated by the displacement of the output shaft 25 around the recess 30 of the body 21 as a center. Then, when the first driver 7 is interrupted and the second driver 8 is energized, the output shaft 25 is pressed. The first driver 7 is rotated around the recess 29 of the body 21 as a center by the displacement of the shaft 25 to the original state.
