Title: Hydrostatic power transmission joint
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1989-04-06
Abstract: PURPOSE:To enable stable operation on an antilock brake system by installing an opening means, pressing a projection of an inlet valve and opening an inlet passage, on the circumference of a rotor at time of sudden slowdown of more than the specified angular acceleration. CONSTITUTION:At time of sudden slowdown of more than the specified angular acceleration and during a discharge process, since high pressure in a plunger chamber 4 is added to an inlet valve 20, a queue spring 36 of a flywheel 35 (opening means) is bent, and rotation of this flywheel 35 is smoothly performed. Even at time of the sudden slowdown, as the queue spring 36 presses a projection 20A of the inlet valve 20 at a suction stroke, the inlet valve 20 will not close an inlet passage 19 in leaving it opened intact. In consequence, since the inlet valve 20 is in a state of being released even if it comes to the next discharge stroke, pressure in the plunger chamber 4 will not go up at all, thus a joint comes to freedom. Therefore both front and rear wheels are isolated from each other just like in a 2WD vehicle so that normal operation on an antilock brake system is performed in this way.

Title: Control device for motor
Inventor: ISHIKAWA JIYUNICHI
IPC: H02P7/292
Filed: 1979-07-12
Abstract: PURPOSE:To smoothly switch a current control to speed control in a motor by smoothly switching only the speed control and the minor current control. CONSTITUTION:When a change-over command A such as a command of starting coating step or the like is applied to a control system switching circuit 12, a control system switching signal B becomes on to switch the contact to produce a current value memory command C so as to store the current feedback amount I at that time in a current value memory circuit 9. Accordingly, a speed control loop such as a speed control amplifier SC or the like is isolated to become a current control mode with the output of the circuit 9 as a current reference. Accordingly, since it is locked to the current value (torque value, tension value) before starting the coating step, tension can be retained constantly. When the speed of the motor M is altered after starting the coating step, a speed set value correcting circuit 16 operates to automatically operate a fine pseed control regulating resistor DRH so that the speed of the motor M and the speed setting potentiometer may become constant. In this manner it can smoothly switch the current control to speed control in the motor.

Title: Separate type optical head and adjusting method for the same
Inventor: TOKIOKA MASAKI
IPC: G11B7/08
Filed: 1990-04-02
Abstract: PURPOSE:To highly precisely and easily adjust the axis of movement by forming reference luminous flux by separating a part of luminous flux at a fixed part, and providing a reflecting plane perpendicular to the axis of movement at the incident part of the reference luminous flux of a translational moving part. CONSTITUTION:The fixed part 3 is provided with a separating and deflecting means 11 which forms the reference luminous flux by separating a part of the luminous flux, and sends the reference luminous flux to the translational moving part 5 in parallel with the direction of an optical path to be inspected between the fixed part 3 and the translational moving part 5, and simultaneously, sends the reference luminous flux coming back from the translational moving part 5 to a light detecting means 21. On the other hand, the translational moving part 5 is provided with the reflecting plane 14 perpendicular to the axis of movement at the incident part of the reference luminous flux. Here, since the reference luminous flux coming back to the light detecting means 21 reflects only the deviation of the axis of movement to the optical path to be inspected, the axis of movement is adjusted by referring to the locus of the reference luminous flux. Thus, the alignment of the axis can be executed highly precisely and in addition, easily.

Title: Linear pulse motor
Inventor: NAKAGAWA HIROSHI
IPC: H02K41/03
Filed: 1983-05-18
Abstract: PURPOSE:To alleviate the influence to the thermal expansion of a core and to reduce noise of a linear pulse motor by applying magnetically attracting forces of steps of a slider of the motor symmetrically to the center line of advancing direction. CONSTITUTION:A linear pulse motor is driven and controlled by a magnetic flux based on a permanent magnet 18 and a magnetic flux based on the excitation of coils 20, 21 provided on a toothed pole for a slider 12. The motor is incremented by the excitation of the poles 13a-13d, 14a-14d, 15a-15d disposed substantially at the equal distance to the center in the advancing direction of the slider 12, and the magnetic fluxes are generated independently at the respective poles. With such a structure, since the magnetically attracting forces of the steps of the motor are applied to the substantially symmetrical positions from the center of the slider 12 in the longitudinal direction of the slider 12, the balance at the front and rear can be always maintained, thereby eliminating the longitudinal movement. In this manner the influence to the thermal expansion of the core can be alleviated, and noise can be reduced.
