    摘要： A variable-damping-force shock absorber includes a piezoelectric actuator for producing a displacement, a hydraulic pressure chamber filled with a working oil and having a volume variable in response to the displacement produced by said piezoelectric actuator, and a plunger slidably disposed in a sleeve and reciprocally movable in response to a change in the volume of said hydraulic pressure chamber. The sleeve and said plunger define therebetween a gap communicating with said hydraulic pressure chamber. A supply passage for supplying a working oil from an external working oil source into said hydraulic pressure chamber extends through the gap. A leakage of the working oil from the hydraulic pressure chamber through the gap can automatically be compensated for by working oil supplied through the supply passage. Since the working oil leaks from and is supplied into the hydraulic pressure chamber through the gap, the leakage and supply of the working oil are kept in equilibrium.

    摘要： An auxiliary steering control system in connection with an anti-skid control system for use in a motor vehicle with two parts of left and right wheels, the anti-skid control system being adapted to independently control braking pressures for at least one pair of left and right wheels and including a braking actuator for adjusting braking pressures to be applied to the pair of left and right wheels. The braking actuator is controlled so that the braking pressures therefor approach the target braking forces determined on the basis of the rotational speeds of the wheels. The steering control device includes a steering actuator for adjusting steering angles of the pair of left and right wheels in response to steering control signals from a steering angle control unit. The steering control unit determines the steering angles of the pair of left and right wheels on the basis of the difference between the braking pressures therefor and outputs the steering control signals thereto so that the pair of left and right wheels assume the determined steering angles.

The non-magnetized part has crystal grain sizes of not more than 30 &mgr;m. The metallic member is subjected to magnetization and successive local non-magnetization of part or parts of the ferromagnetized member, and the thus obtained composite magnetic member is employed as a support member such as a sleeve in electromagnetic valves.
