Title: Ultrasonic motor
IPC: H02N2/00
Filed: 1992-03-24
Abstract: PURPOSE:To reduce consumption current at the time of step drive of a moving body by temporarily stopping drive pulse oscillation only during a period when the moving body can be moved by means of inertial force even if the drive pulse oscillation is stopped. CONSTITUTION:Ultrasonic oscillation generation circuits 2007, 2008, 2009 serve to generate standing wave respectively, an oscillation body 2012 is excited and a moving body 2013 is step-driven. A drive pulse storing circuit 2001 serves to store a drive pulse for generating supersonic oscillation. A quiescent time storing circuit 501 serves to store a period when the moving body can be moved by means of inertial force even if drive pulse oscillation is stopped on the way where the moving body is being driven by means of drive pulse oscillation. A stop period oscillation circuit 502 serves to oscillate a quiescent pulse stored within the quiescent pulse period storing circuit 501 and temporarily stop the drive pulse oscillation. At a time point when the moving body cannot be driven by means of self-inertia, the drive pulse oscillation is reopened to repeat step drive. Thereby consumption current is reduced.

Title: Motor
IPC: H02K7/06
Filed: 1991-03-29
Abstract: PURPOSE:To bring a valve mounted on a shaft into a required switching state surely, by enabling the shaft to move easily even though the energizing force of a spring is small when one coil of a motor is disconnected. CONSTITUTION:In a motor, the rotation of a rotor 25 is converted into the linear motion of a shaft 27 by screw parts 30, 31 provided respectively on the rotor 25 and the shaft 27. In the motor, when a disconnection is generated in the coil of one phase among the four phases of the motor, the coil of another phase opposed to the disconnected phase is disconnected forcedly, and the four- phase motor is switched to a two-phase motor. Then, by applying pulses to the coils of the residual two phases, the position of the shaft 27 is prevented from being fixed. Thereby, even though the force of a spring, by which the shaft 27 is energized in a required direction, is small, the shaft 27 can be moved easily.
