Filed: 1989-06-01
Abstract: PURPOSE:To simplify the mechanical structure by rotating a motor in response to the deviation between all operating dial and a pulley, and driving a governor of a throttle valve or the like with the motor, and stopping the motor attending on the dissipation of the described deviation. CONSTITUTION:When an operating dial 7 of a controller 3 is set at the predetermined angle under the condition that an engine is rotated, the deviation is generated between the operating dial 7 and a feedback pulley 8. A motor M of an actuator 2 is rotated normally or reversely in response to the deviation to rotate an output pulley 6 through a speed reducer 5. As a result, an engine pulley 1 is rotated through a control cable 9 to operate a governor 4. On the other hand, the rotation of the engine pulley 1 is transmitted to the feedback pulley 8 through a feedback cable 10. When the deviation between the feedback pulley 8 and the operating dial 7 becomes 0, the rotation of the motor M is stopped.

Title: Method and mechanism for driving screw rod by ultrasonic vibration
Inventor: FUJIMURA KATSUYUKI
IPC: H02N2/10
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To automatically adjust a screw rod without play by integrally forming a vibrator and a piezoelectric actuator, and applying a constant pressure to the circumference of the screw rod from the vibrator and a clockwise or counterclockwise rotating voltage across the right or left side of the vibrator. SOLUTION: A screw rod 2 is mounted on screw rod pedestals 3 and 3 via bearing 4 and 4, and a piezoelectric actuator 6 with vibrator is integrally formed with a vibrator pedestal 5. Then springs 8 are set by compressing the springs 8 by means of spring clamping locking tools 9. Consequently, the vibrators of the actuator 6 always give large friction to the circumference of the rod 2 by pressing the rod 2 with constant pressures. When a voltage is applied across the vibrators 7 (a) and 7(d) therefore, the actuator 6 rotates counterclockwise, and when a voltage is applied across vibrators 7(b) and 7(c) conversely, the actuator 6 rotates clockwise and the vibrator pedestal 5 moves on rails 11. Accordingly, no play nor backlash occurs, even if frictional sections of the vibrators are slightly worn.
