Title: Commutator unit
Inventor: ONUMA HIDEO
IPC: H02K13/00
Filed: 1988-11-09
Abstract: PURPOSE:To improve the reliability of a commutator, by arranging an insulation protective member for sealing the endface of the commutator and the sideface at the step section of a tubular insulator hermetically. CONSTITUTION:A space is provided between the endface 6 of a commutator and the endface 8 at the step section of a tubular insulator 3 then a raw fluoro- rubber 10 is mounted thereon, thereafter it is heated and pressed to form the elastic insulator for an insulation protective member 9. Variation at the step section due to differential thermal expansion between a commutator chip 1 and the tubular insulator 3 caused by temperature variation produced through operation/stoppage of an electric rotary machine is absorbed through elastic deformation of the insulation protective member 9. Since raw rubber 10 is vulcanized to the endface 6 of commutator and the endface 8 at the step section, the hermetically sealed state is held continuously thus preventing accumulation of dust. Furthermore, since anti-adhesion performance of dust is improved through tetraethylene fluoride resin coating applied onto the outer surface of the elastic rubber body, dust-proof effect can be improved furthermore.

Filed: 1994-10-24
Abstract: PURPOSE: To prevent the influence of the variation of the cross-sectional shapes of conductor layers and resistor layers having prescribed shapes on the electrical characteristics of a thin film circuit in which the conductor layers and resistor layers are formed at the time of forming films. CONSTITUTION: After a metallic base film 12 is formed on a substrate 10, resist layers 11 are formed on the film 12 in a prescribed pattern. Then conductor layers La-Ld and Lp1 are formed by plating between each resist layer 11. A thin film coil body is formed of the conductor layers La, Lb, and Lc. Part of the cross section of the outermost conductor layer Ld tends to become thicker due to an internal stress in the plating process. Therefore, the outermost layer Ld is not used as a conductive layer, but as a dummy line. Accordingly, the cross-sectional shapes of the conductor layers La, Lb, and Lc constituting the thin film circuit are stabilized and the inductance fluctuation of the circuit can be reduced.

Title: Speed control device
Inventor: KAWADA SHOJI
IPC: F02D29/00
Filed: 1986-11-29
Abstract: PURPOSE:To improve the responsiveness to speed changes by correcting speed change timer means in response to a change of the car speed deviation during the operation of multiple timer means prohibiting the speed change of an automatic speed change control means corresponding to the car speed deviation. CONSTITUTION:If a mode switch MS is set to the position A for the automatic speed change/constant-speed travel control mode, a microcomputer CPU drives a release valve RV and a control valve CV in response to the deviation between the car speed from a speed sensor SP1 and the constant-speed travel preset speed set by a set switch SP and a resume switch RS to perform the constant- speed travel control. In this case, the speed change operation is prohibited and delayed in the period of multiple built-in speed timers. During this prohibition, if the car speed deviation is changed to the extent that the lock-up state can not be maintained, the set period of the speed change timers is corrected. Accordingly, the number of speed changes due to the overshoot of the throttle control during the constant-speed travel is decreased, and the responsiveness to speed changes can be improved.
