摘要： A rod is inserted in a first cylinder. A first oil chamber is defined by the inner surface of the first cylinder. The rod can be reciprocated with a first stroke. A second cylinder is coupled to the first cylinder by a connecting member. A metal bellows is housed in the second cylinder. A gas chamber is defined by the inner surface of the bellows. A second oil chamber is defined by the outer surface of the bellows and the inner surface of the second cylinder. The bellows contracts with a second stroke corresponding to the first stroke of the rod. The first and second oil chambers communicate with each other via an oil path formed in the connecting member. A valve seat is arranged on an end wall of the second cylinder. A valve body is fixed to the bellows so as to oppose the valve seat. If the bellows expands farther than the second stroke when a gas is supplied into the gas chamber, the valve body is brought into contact with the valve seat. When the valve body and the valve seat are brought into contact with each other, the oil is entrapped in a gap between the inner surface of the second cylinder and the outer surface of the bellows body.

摘要： A suspension system according to the present invention comprises a cylinder piston mechanism and a sub-tank. A main gas chamber is defined inside the cylinder piston mechanism, while a sub-gas chamber is defined inside the sub-tank. An oil chamber, filled with oil, and an oil passage are arranged between the main and sub-gas chambers. The oil passage is opened and closed by means of a control valve, which has a rotating valve plug for controlling the oil flow. When the control valve is open, the main and sub-gas chambers change their respective capacities simultaneously as a rod reciprocates. When the valve is closed, only the main gas chamber changes its capacity as the rod reciprocates. The control valve is provided with a spring-constant changing orifice and a damping-force changing orifice, whereby the spring constant and damping force of the system are changed simultaneously, in accordance with the rotational position of the valve plug.

摘要： An apparatus for controlling the friction between the leaf springs of a laminated leaf spring assembly comprises a clamping mechanism, a hydraulic cylinder mechanism, a hydraulic control mechanism and a detecting mechanism. The clamping mechanism includes a guide member and a press member. The guide member and the press member hold and clamp the laminated leaf spring assembly. The detecting mechanism detects the values of the predetermined factors of a body supported by the laminated leaf spring assembly and supplied signals representative of the values to the pressure reducing valve. According to the signals from the detecting mechanism the pressure reducing valve controls the pressure of the liquid supplied to the cylinder of the hydraulic cylinder mechanism. The detecting mechanism includes a pressure sensor for sensing the pressure of the compressed oil acting on the power steering assembly and a comparator for comparing a signal from the pressure sensor with a predetermined value and for supplying a signal corresponding to the sensed pressure to the control valve when the sensed pressure exceeds the predetermined value.

摘要： Provided is an actuator for scanning detecting light, comprising an optical element for emitting detecting light, a moveable part supporting the optical element, a sheet spring having a fixed end and a moveable end supporting the moveable part; and drive means for driving the moveable part so as to scan the detecting light. Thus, a spring-mass system is formed in which the moveable part retaining the optical device acts as the mass, and the first order resonant frequency of the system may be selected so as to be higher than the operating frequency (scanning frequency). A bearing for a sliding part is not required, and the resistance loss can be thereby eliminated. These factors contribute to a favorable responsiveness. Also, by properly designing the sheet spring, a lighter and more compact design is enabled than would be possible with the conventional arrangement. A plurality of drive force generating units disposed on either side of the optical element in such a manner that the combined force of the drive force produced by the drive force generating units acts substantially onto the gravitational center of the moveable part. Thus, the drive efficiency can be improved while saving energy and achieving a high level of responsiveness.

摘要： A tire inflation pressure monitoring apparatus comprises a reference magnet fixed to a wheel, a movable magnet whose position shifts depending on the inflation pressure of a tire, and a magnetic sensor for detecting the magnetism of the magnets. The reference magnet can be moved in the axial direction of the wheel by means of a position adjusting mechanism. Thus, a relative distance from the reference magnet to the movable magnet can be adjusted to a fixed value (e.g., zero) at the time of calibration. An electric circuit section is stored with a computation formula or a map indicative of the relationships between outputs of the magnetic sensor and minimum distances from the magnets to the magnetic sensor. In detecting the inflation pressure of the tire, data associated with the minimum distances from the magnetic sensor to the magnets are obtained according to the computation formula or map on the basis of the outputs obtained by means of the magnetic sensor. Based on these data, the inflation pressure of the tire is obtained according to a pressure computation formula or a map indicative of the relationship between the tire inflation pressure and the distance between the magnets.
