Title: Earth structure of record reproducing device
Inventor: ISHIKAWA JUN
IPC: G11B33/14
Filed: 1995-02-28
Abstract: PURPOSE: To provide the earth structure of a tape recorder the cost of which is reduced by reducing the number of part items and the manhour of assembly. CONSTITUTION: A protrusion 11j with recessed back face, for example, 3mm thick and, for example, 6mm across is formed to be near the limit of plastic working at the left front corner of the bottom of a chassis 11 made of metal by deep drawing. A cylinder 71 made of synthetic resin is attached integrally to the section by outsert molding so that the depth H may be 7.1mm. A printed wiring board 72 is screwed with an earth screw 73. Hereby, the earth pattern of the printed wiring board 72 and the protrusion 11j of the chassis 11 are conductive through the earth screw 73, and static electricity, etc., are removed. This eliminates the necessity to separately attach another parts such as a metallic board mounting shaft, etc., to the chassis 11 by calking, or the like, and by that amount, the number of part items and the manhour of assembly are reduced, and the whole cost can be reduced.

Title: Motor output torque controller
Inventor: KANEKO RYOJI
IPC: H02P29/00
Filed: 1995-02-28
Abstract: PURPOSE: To provide a motor output torque controller in which the fluctuation in the auxiliary output torque can be suppressed regardless of the fluctuation factors of a motor or the like. CONSTITUTION: Imaginary r.p.m.-torque characteristics having a variation rate of r.p.m. higher than that of the inherent r.p.m.-torque characteristics of a motor 12 are stored in a voltage setting means 16 which calculates or reads out a voltage corresponding to a target value of auxiliary torque and r.p.m. from the imaginary r.p.m.-torque characteristics. Since the variation rate of r.p.m. is high in the r.p.m.-torque characteristics stored in the voltage setting means 16, the variation of torque is low with respect to the variation of r.p.m. Consequently, the fluctuation of auxiliary torque can be suppressed even if the relationship between the r.p.m. and the actual auxiliary torque is fluctuated owing to the fluctuation factors of the motor 12 or the like.
