Title: Antiskid control device for vehicle
Inventor: NUMATA KENICHI
IPC: B60T8/34
Filed: 1986-01-07
Abstract: PURPOSE:To prevent a proportional distributing valve from being frequently operated, by disposing the proportional distributing valve between a master cylinder and a solenoid selector valve for regulating the pressure in each wheel cylinder, by circulating brake fluid in a reservoir between the master cylinder and the proportional distributing valve. CONSTITUTION:During antiskid control a pump 48 is driven so that pressure oil in wheel cylinders 14, 16 relieved into a reservoir through three position selector valves 13, 34 and a return pipe 20, and therefore, the rotation of each wheel is recovered. Thereafter, when the rotational speed of the wheel exceeds a reference speed, the three position selector valves 18, 34 are changed over into their communicating positions so that pressure oil is fed into the wheel cylinders 14, 16 to restrain the rotation of the wheel. During this control, a constant pressure is fed from the pump 48 to the upstream side of proportional distribution valve 32, and therefore, the output of the proportional distribution valve 32 is made to be constant. Accordingly, the proportional valve 32 holds the one and the same operating position, irrespective of variations in pressure downstream of the three position selector valve 34.

Title: Overcurrent protective controller for servo motor
Inventor: UCHIDA HIROYUKI
IPC: H02P7/29
Filed: 1988-01-09
Abstract: PURPOSE:To prevent demagnetization of a magnet due to overheat, by monitoring actual drive current flowing through a servo motor and performing overcurrent protection thereby interrupting current in early stage. CONSTITUTION:Upon provision of a position command, a current command means 10 provides a current command corresponding to rotary information of a servo motor 22 to a current control means 12, which produces a PWM signal. The PWM signal is transmitted through a communication control means 14 to a current supply means 16, which then performs PWM control and feeds driving current to the servo motor 22. The driving current is detected through a current detecting means 18, and when the magnitude of the driving current exceeds over a specific value, a current monitoring means 20 interrupts the PWM signal and cuts off the driving current. Since the driving current can be cut off with response as high as several hundred muS, demagnetization of magnet can be prevented.

Abstract: PURPOSE:To eliminate adverse influence onto the mechanical accuracy of motor shaft or turn table by supplying power to the extension of stator winding and producing flux for attracting a press member in the axial direction of motor shaft thereby pressing a disc against a turn table. CONSTITUTION:A thrust bearing 9a contacting slidably with the end 5a of a motor shaft 5, in order to prevent fall off of a rotor 6 and to bear the thrust load of the rotor 6, is arranged in a housing 8. Extensions 4a of two or more phases of stator windings 4 are arranged on the motor 5 shaft side face of the housing 8, and power is fed to the extensions 4a to produce flux for attracting a press member 14 in the axial direction of the motor shaft 5 thus pressing a disc 12 against a turn table 13.
