    摘要: A proportioning valve assembly has a supply port through which a pressurized working fluid is supplied, a drain port through which a pressurized working fluid is drained, and a control port connected to a working chamber defined in a hydraulic cylinder disposed between a vehicular body and a suspension member rotatably supporting a vehicular wheel. The proportioning valve assembly further includes a valve member for adjusting working fluid pressure to be supplied to the working chamber via the control port. A flow restricting orifice is provided in the proportioning valve assembly. The flow restricting orifice employed is designed to provide variable flow restriction depending upon working fluid condition and/or the direction for achieving stabilization of pilot pressure or road shock absorption.

    摘要: An SR motor includes a stator having a plurality of salient poles and a rotor having another plurality of salient poles. Windings are wound around the plurality of salient poles and magnetic fields are generated in the plurality of salient poles. The number of salient poles of the rotor is determined depending upon a number of the salient poles of the stator. A supply mode for supplying power from a power supply to the windings, a reflux mode for setting both terminals of the windings to an identical potential, and a regenerative mode for recovering an electromotive force generated in the windings into the power supply are executed as the rotor rotates. The reflux mode and the regenerative mode are preferably repeated in a period during which the inductance of the windings is reduced as the rotor rotates.

    摘要: A brake pressure is controlled with the left and right front wheels of a vehicle as one group, and the left and right rear wheels as another group. Alternatively, the right front wheel and left rear wheel form one group, and the left front wheel and right rear wheel form another group. Brake pressure is supplied individually to these groups by a first actuator group comprising one or more actuators and a second actuator group comprising one or more actuators. When a fault occurs in an actuator in the first actuator group, the first actuator group is controlled so as not to generate brake pressure, and when a fault occurs in an actuator in the second actuator group, the second actuator group is controlled so as not to generate brake pressure. In this way, unbalance of braking force on the left and right wheels due to a fault in an actuator is prevented, and turning of the vehicle due to this unbalance is suppressed.

    摘要: A piezo-actuator's displacement magnifying mechanism includes a first cylinder and a second cylinder which is smaller in diameter than the first cylinder and communicates with the same. A plunger is slidably mounted in the first cylinder. The plunger is moved by a piezo-actuator in the first cylinder when a predetermined voltage is applied to the piezo-actuator to cause the same to expand and contract. A piston is slidably mounted in the second cylinder. A reservoir is communicating with the first cylinder. A hydraulic fluid is received in the first and the second cylinder and the reservoir. The hydraulic fluid is variable in viscosity in response to electric fields to which the fluid is subjected. A fluid passage is provided between the first cylinder and the reservoir for compensating for thermal expansion/contraction of the fluid. An electrode is provided for subjecting the hydraulic fluid to electric fields in the passage according to an instruction for applying the voltage to the piezo-actuator.

    摘要: An emergency locking retractor is constructed of a base having an engaged portion; a take-up spindle supported displaceably in a direction perpendicular to the longitudinal central axis thereof; a movable member supported rotatably about the spindle; a holder for normally holding the movable member unrotatably; a clutch mechanism for connecting the spindle and the movable member to each other when the spindle undergoes a rotational speed change; a ratchet member provided as a unitary member with the spindle, said ratchet member being engageable with the engaged portion to prevent any further rotation of the spindle when a tensile force is applied to the spindle and the spindle is displaced in the direction perpendicular to the longitudinal central axis thereof; and a clutch mechanism releasing device for causing the movable member to turn in a webbing-releasing direction when the ratchet member and engaged portion are in mutual engagement.
