Title:
ULTRASONIC LINEAR MOTOR
Document Type and Number:
Japanese Patent JPH044774
Kind Code:
A
Abstract:
PURPOSE: To control the moving speed of a slider to a predetermined speed, to control the slider at a predetermined holding force and to hold it by varying the pressing force of the slider in pressure contact with a transmission rod, and controlling the driving force and the holding force of the slider.
CONSTITUTION: A slider 4 is pressed by a pressure regulating mechanism 5 to be driven by regulable fluid pressure, and the pressing force of the slider 4 in pressure contact with a transmission rod 3 is varied by the pressing of the mechanism 5. Thus, the driving force, the holding force of the slider to be determined by a friction coefficient between the rod 3 and the slider 4, the pressing force can be controlled.
