Title: Ultrasonic motor
Inventor: UMEDA MIKIO
IPC: H02N2/00
Filed: 1991-08-14
Abstract: PURPOSE:To make it possible for a minor rotor to utilize only the rotational force of the oval motion which is generated by a ultrasonic motor by providing the minor rotor capable of obtaining the rotational force from a stator through a spring member in addition to the main rotor which directly moves slidingly together with the stator. CONSTITUTION:When a stator head 18 and a main rotor (ML) 32 are caused by a spring member 36 to be in contact under pressure and a voltage is impressed to an torsional oscillator 11, both of them generate displacements by the torsional vibration in its circumferential direction. Hence, the ML 32 rotates at a fine angle. When the pressure is reduced by use of a vertical oscillator 16 after the rotation, the torsional amount is offset and eliminated. Here, the voltage is again impressed to the torsional oscillator 11. Then, the ML 32 again rotates at the fine angle. Further, the spring member 36 is mounted on the ML 32, and a minor rotor 38 is fixed through an upper washer 42, that is, driving a ultrasonic motor causes the minor rotor 38 to generate a rotational motion. Particularly, the vertical vibration generated by the ML 32 is absorbed by the spring member 36. Therefore, any unwanted vibration is not transmitted to the minor rotor 38.

Title: Video disc player
Inventor: SHIMIZU KEIZOU
IPC: G11B21/08
Filed: 1982-11-24
Abstract: PURPOSE:To reduce noises transiently appearing on a regenerative screen at its minimum as possible by discriminating whether the picture No. of a track to be driven and fixed is correctly decoded or not by a discriminating means and adjusting the driving timing in accordance with the probability to be correctly decoded. CONSTITUTION:If a signal detecting part 2 generates a locked group phenomenon reproducing the same track repeatedly due to the defect of the disc during the reproducing of the disc, a picture No. discriminating part 5 can excite a driving part 7 and discharge a signal detecting part 2 forcedly from a disc defect part (release of the locked group) because the update of the No. is not permitted. Thus, the discriminating part 5 discriminates whether the picture No. of the track to be moved is correctly decoded or not by a decoding part 4 after driving without setting up the driving part of the signal detecting part 2 fixedly and the discriminating part 5 controls a driving position determining part 6 so that the correctly decoded probability is maximized, so that the driving position of the signal detecting part 2 is variably controlled.
