Abstract: A main liquid chamber communicates with a first auxiliary liquid chamber and a second auxiliary liquid chamber via a first limiting passage and a second limiting passage, respectively. The first and second auxiliary liquid chambers are located adjacent first and second air chambers via first and second diaphragms, respectively. As a solenoid valve is changed over, the second air chamber is made to communicate with the negative pressure of an engine or the with atmospheric pressure. The second liquid chamber is disposed in a hollow cylindrical member. When frequencies of vibrations are below a predetermined frequency, the negative pressure of the engine is transmitted to the second air chamber, causing the second diaphragm to be brought into close contact with and fixed to an inner wall of the second air chamber. As a result, a liquid passing through the first limiting passage absorbs the vibrations.

Abstract: A damper device has a fixed member and a movable member, one being inside of the other. An electroviscous fluid is sealed between these two members, and opposed electrodes are arranged at respective positions of the two members to allow relative flow of the electroviscous fluid. The portions of the movable and fixed members that are in sliding contact are shielded against the electroviscous fluid by a flexible member between these two members. In an apparatus for manufacturing semiconductors according to the invention, an arm is provided on the movable member to move along the axial direction of the guide bar when the movable member moves. A flexible member is provided between respective ends of the fixed guide bar and respective ends of the arm to maintain the internal space liquid-tight, and an electroviscous fluid is sealed inside the flexible member and between the arm and the guide bar.

Abstract: A vibration damping apparatus which is particularly applicable to an automotive engine mount and capable of fully absorbing vibration from vibration generating sources. A sleeve is secured to the automotive engine unit, and a housing is secured to the vehicle body. Once the vibration generated by the automotive engine is transmitted to the sleeve, liquid loaded in a main liquid chamber flows to a sub liquid chamber via a plurality of restricting passages. Vibration is effectively absorbed by the transit resistance against liquid flowing through those restricting passages. Independent of these restricting passages, a cylindrical member is provided which penetrates through the housing and a partition wall block. The cylindrical member is disposed in the path of the restricting passages providing connection between the main and sub liquid chambers. A hollow rotor is rotatably provided, inside of and on the same axial line as the cylindrical member, for opening and closing the restricting passages.

Abstract: A vibration isolation apparatus comprises a first auxiliary fluid chamber communicating through a first restricted path with a main fluid chamber and a second auxiliary fluid chamber communicating through a second restricted path with the main fluid chamber. The second restricted path has electrode plates whose power supply condition is controlled by a control unit. Further, an electric viscous fluid is filled in the main fluid chamber, the first and second auxiliary fluid chambers, and the first and second restricted paths. When shake vibration is generated, the electrode plates are energized by the control unit so that none of the electric viscous fluid flows through the second restricted path. The electric viscous fluid causes a resonance of the fluid, and has flow resistance in the first restricted path to absorb the shake vibration. Idle vibration sets the first restricted path in the loading condition to prevent the electric viscous fluid from flowing through the restricted path.

Abstract: A vibration isolating apparatus interposed between a vibration-occurring portion and a vibration-receiving portion includes a liquid chamber partitioned into a plurality of small liquid chambers, an orifice allowing the small chambers to communicate with each other, and an electroviscous fluid filled in the liquid chamber and the orifice. Disposed in the liquid chamber are a movable plate for partitioning the liquid chamber, a groove portion for accomodating a peripheral edge of the movable plate in such a manner as to be movable in a thicknesswise direction of the movable plate by a predetermined amount, and a pair of electrodes for imparting an electric field to the electroviscous fluid in the groove portion. Hence, when the vibration isolating apparatus receives low-frequency vibrations, the pair of electrodes are energized to increase the viscosity of the electroviscous fluid between the electrodes, allowing the movable plate to be secured in the groove.
