Title: Recording medium player
Inventor: SHIBAZAKI MITSUAKI
IPC: G11B19/02
Filed: 1992-12-14
Abstract: PURPOSE:To simplify operation of random play by playing information recorded on all recording media contained in a plurality of play driving means randomly in series depending on commands delivered from a control means. CONSTITUTION:When a random play mode is set by means of a play mode key 6 on a main control body 1, a CPU9 selects any one of a plurality of play driving means 11a-11d automatically to designate random play of recording medium. Consequently, each means 11a-11d can play information recorded on all recording media contained therein randomly in series depending on commands delivered from the CPU9 thus allowing easy random play without requiring troublesome operation. Preferably, the CPU9 designates random play after execution of random calculation based on offset values determined every time when the play is ended for all means 11a-11d, all recording media, and all tracks.

IPC: H01L41/09
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of electromagnetic wave noise by electrically- insulating a stator from a housing. SOLUTION: This ultrasonic motor 1 is provided with an insulating plate 8 between a stator 10 and a base 3 of a housing 2, and the stator 10 is fixed on the base 3 of the housing 2 via an insulating washer 14. An insulating collar 17 is put between a rotor 16 and a rotational shaft 6. The stator 10 and the rotor 16 are in an electrically insulated condition from the base 3 of the housing 2, therefore the stator 10 is not grounded via a metal substrate 9 and the housing 2. The ground electrodes of respective piezoelectric elements 12a to 12c are grounded by an ECU 19 via a lead wire 20d, and a ground wire 22d. As a result, a ground current due to drive voltage for applying to the piezoelectric elements does not flow into the ground through the housing of the ultrasonic motor, thus it is possible to reduce the generation of electromagnetic wave noise.
