    • A control section outputs a reference signal which corresponding to a frequency and an amplitude of signals sent from a vibration generation source. The pulse width modulation section generates a drive control signal to, an electromagnetic valve, connection of an air chamber and is alternately switched between the side of an inlet port and the side of the atmosphere. The drive control signal corresponds to an amplitude of the reference signal and is composed of at least the same number of pulses corresponding to a duty ratio-changed frequency as that of each one period of the standard signal. The drive control signal is synchronized with the standard signal. The number of pulses of the drive control signal for each period of the reference signal is changed corresponding to a control frequency of the standard signal so that the number of pulses and the control frequency is not larger than a responding frequency of the electromagnetic valve.

    • A fluid-filled elastic mount wherein an elastic body elastically connecting first and second supports partially defines a fluid chamber filled with a non-compressible fluid. The elastic mount includes an oscillating plate which partially defines the fluid chamber and which is displaceable to change a pressure of the fluid in the fluid chamber, and a permanent magnet disposed on one of opposite sides of the oscillating plate remote from the fluid chamber. The permanent magnet is made of a plastic magnetic material including a magnetic material and a plastic material as a binder for the magnetic material. First and second yoke members are held in contact with opposite magnetic pole faces of the magnet, and cooperate with the magnet to define a close magnetic circuit. The yoke members define therebetween an annular gap in the magnetic circuit, in which an annular moving coil is received. The coil is fixed to the oscillating plate, to oscillate the oscillating plate upon energization of the coil. Also disclosed is a method of manufacturing the elastic mount, in which a spacing between the yoke members is filled with the plastic magnetic material in a plasticized state, which is then solidified to provide the permanent magnet.

    • A mounting device such as an engine mount for automobiles, which receives various types of vibrations over a wide frequency range, is required to exhibit a low dynamic spring constant with respect to the input vibrations in a middle- to high-frequency range, while assuring high damping characteristics with respect to the input vibrations in a low frequency range. The present invention provides a fluid-filled mounting device wherein a pressure-receiving chamber (38) which receives vibrations and a variable-volume equilibrium chamber (40) are disposed between a first and a second support member (10, 14) which are elastically connected to each other by an elastic rubber body (26), such that the pressure-receiving and equilibrium chambers are filled with a predetermined non-compressible fluid, and are held in communication with each other via an orifice passage (46), and wherein a movable member (54) is movably accommodated in the pressure-receiving chamber (38) while a support member is provided for preventing the movable member (54) from contacting the inner wall of the pressure-receiving chamber (38) whereby a resonance portion having a predetermined space is formed around the movable member (54), so that the fluid is caused to flow through the resonance portion upon application of the vibrations. The mounting device according to the present invention can exhibit a high damping effect against the input vibrations in a low frequency range, due to a resonance of the fluid flowing through the orifice passage (46), and can also provide a low dynamic spring constant against the input vibrations in a middle- to high-frequency range, due to a resonance of the fluid flowing through the resonance portion formed around the movable member (54).
