Inventor: FUKUI TAKASHI
IPC: E05B77/36
Filed: 1988-03-15
Abstract: PURPOSE:To prevent generation of noise by using an ultrasonic wave motor as a driving source for door locking. CONSTITUTION:In an actuator for a door locking device, an ultrasonic wave motor 4 is installed within a case 3 of a hollow box formed by a housing 1 and a cover 2. A pinion gear 6 fixed to the shaft 5 of said motor 4 is caused to engage directly with a rack 7 connected with a door locking member, and the rack 7 is moved in the direction of the arrow according to the forward or reverse direction of the rotation of said gear 6. To constitute this motor 4, a cylindrical elastic body 10 is fixed to the housing 1 by screws and the like for joining a piezoelectric body P and for pressure-fitting a rotor 9. Also, a collar part 5a is integrally formed in the shaft 5 to energize the rotor 9 via vibroisolating rubber 12 by a disc spring 11 and to pressure-fit said rotor to the elastic body 10. Thus, because of its high torque and slow rotation, the motor 4 can be driven directly by no way of any gear reduction mechanism.

Abstract: PURPOSE:To attain the acceleration of operating speed and a low cost due to the simplification of circuit constitution by providing plural phase locked loops by using variable frequency oscillators with the same characteristic, and using the output signal of a loop filter generated by the phase locked loop on one side in control for the phase locked loop on the other side.
