An active antivibration device which includes a main body, a mobile element which is elastically supported inside the main body and movable in an axial direction of the main body, and a coil which is disposed inside the main body and fixed to the main body. The mobile element includes a mobile axis body supported in the axial direction of the main body, and a first yoke, a permanent magnet and a second yoke which are held by the mobile axis body and disposed successively along an axial direction of the mobile axis body. The permanent magnet is magnetized in the axial direction of the mobile axis body and disposed between the first yoke and the second yoke.
摘要:
A semiconductor integrated circuit is a synchronous semiconductor integrated circuit which operates in synchronism with a clock signal, and includes memory cells, bit lines, a pre-charge circuit and a pre-charge controlling circuit. The memory cells store information, and are connected to the bit lines. The pre-charge circuit performs a pre-charge operation for pre-charging a bit line. The pre-charge controlling circuit controls the pre-charge operation of the pre-charge circuit. The pre-charge controlling circuit synchronizes starting of the pre-charge operation with the edge of the clock signal.

A fluid-filled type active vibration damping device including a vibration damping device main unit, an oscillation member, and an actuator. The actuator is constituted by an electromagnetic actuator having a stator that includes a coil fixed to a second mounting member while having a movable member linearly displaceable relative to the stator when the coil is energized. A shaft member is provided for connecting the movable member and the oscillation member with each other. A connecting portion is provided for attaching the shaft member to the movable member while permitting the shaft member to tilt as well as to undergo displacement in an axis-perpendicular direction with respect to the movable member. A displacement preventing portion is provided for fastening the movable member and the shaft member to each other by preventing tilt as well as displacement in the axis-perpendicular direction due to the connecting portion.
