摘要： A variable displacement compressor having a rotary shaft and a swash plate is described. The swash plate is mounted on the shaft and rotates integrally with the shaft. The swash plate tilts between a maximum inclined angle and a minimum inclined angle and is connected to a plurality of pistons. The inclined angle of the swash plate is altered by the difference between the pressure in a crank chamber and the pressure in a suction chamber. Each piston reciprocates inside a cylinder bore with a stroke determined by the inclined angle of the swash plate and compresses refrigerant gas, which includes oil mist. A spool is arranged adjacent to the swash plate on the shaft. On the shaft, a thrust bearing is provided between the swash plate and the spool, and a radial bearing is provided in the spool. The spool has an opening opposed to the swash plate. Grooves that allow the flow of refrigerant gas into the spool are formed at the opening in the walls of the spool.

摘要： A variable displacement compressor includes a swash plate, which is rotatably supported on a drive shaft in a crank chamber. The crank chamber is connected to a discharge chamber through a pressurizing passage. An electromagnetic control valve is located in the pressurizing passage. When the control valve opens the pressurizing passage, pressure in the crank chamber increases and inclination of the swash plate decreases. When the control valve closes the pressurizing passage, the pressure in the crank chamber decreases and inclination of the swash plate increases. A fixed restrictor is located in the pressurizing passage. When the control valve suddenly opens the pressurizing passage, the fixed restrictor limits the flow rate of gas in the pressurizing passage so that the pressure in the crank chamber gradually increases. Accordingly, the inclination of the swash plate gradually decreases, thus reducing vibration and noise.

摘要： A compressor comprises a plurality of compression chambers used for compressing gas. A gas chamber includes one of a suction chamber for supplying the gas to the compression chambers and a discharge chamber for receiving the compressed gas from the compression chambers. A plate member is located between the compression chambers and the gas chamber. The plate member has a plurality of ports respectively arranged in association with the compression chambers for connecting each compression chamber with the gas chamber. A plurality of valve flaps are respectively arranged in association with the ports. Each of the valve flaps faces the plate member to selectively open and close the associated port. Each valve flap has a proximal end supported on the plate member. The plate member has at least one groove formed thereon and facing the proximal end of each valve flap. Foreign matter enters between the proximal end of each valve flap and the plate member and is collected by the groove. The groove extends over at least two valve flaps.

摘要： A housing of a compressor has a shutter chamber for accommodating a shutter. The shutter moves between a closed position, where the shutter stops flow of gas from an external circuit into a suction chamber, and an open position, where the shutter permits the gas flow in response to the tilting motion of a swash plate. A coil spring, which has a conical shape, is located in the shutter chamber to bias the shutter in a direction toward the open position from the closed position. The spring is arranged to prevent the spring from sliding against the inner wall of the shutter chamber when the spring is expanded or contracted by movement of the shutter member.

摘要： A refrigerant compressor having a drive shaft rotatable to cause compression of a refrigerant gas, and a drive power transmission unit for transmitting a drive power from an external drive power source to the drive shaft, the drive power transmission unit having a pulley freely rotatably mounted around the drive shaft, a power transmitting element fixed to the drive shaft, and a shock absorbent rubber element arranged between the pulley and the power transmitting element for providing a positive engagement between the rubber element and the pulley, and between the rubber element and the power transmitting element. The shock absorbent rubber element absorbs a change in a load torque applied to the compressor before the torque change is transmitted to the external drive power source via the pulley, and disengages from at least one of the pulley and the power transmitting element when an excessive load torque is applied to the compressor to interrupt transmission of the excessive load torque from the compressor to the external drive power source.

摘要： A housing includes a crank chamber and cylinder bores. Pistons are accommodated in the cylinder bores. A drive shaft is supported by the housing to pass through the crank chamber. A lug plate is fixed to the drive shaft. The pistons are coupled to the lug plate, which converts rotation of the drive shaft into reciprocation of the pistons and compresses gas in the cylinder bores. A thrust bearing is located between the housing and the lug plate and transmits a thrust load applied to the lug plate. The thrust bearing includes a front race located next to the housing, a rear race located next to the lug plate, and rollers located between the front and rear races. A front seat for supporting the front race is formed on the housing. A rear seat for supporting the rear race is formed on the lug plate. The diameters of the front and rear seats are different, which causes elastic deformation of the races when a thrust load is applied.

摘要： In the manufacturing process of a Bi-CMOS semiconductor device, which includes a CMOSFET and a bipolar transistor, the steps for forming a well region, source regions, and drain regions of the CMOSFET are also used for forming the bipolar transistor. One of the steps is used for introducing impurities of the same conductivity type in a surface of a base region of the bipolar transistor in order to form a high impurity concentration region in the surface. The high impurity concentration region is formed such that the distance between an emitter region of the bipolar transistor and the high impurity concentration region becomes 1 to 2 &mgr;m. The shift in device characteristics of the bipolar transistor is improved by the high impurity concentration region even if the impurity concentration is relatively low at the surface of the base region of the bipolar transistor.

摘要： One or more capacitors are formed using thermally oxidized films formed on a silicon layer of an SOI substrate. The capacitors may be formed alone or together with other semiconductor elements on a single SOI substrate. A diffuse layer having an impurity in a high density is first formed on the silicon layer, and then an oxidized film is formed on the diffused layer by thermal oxidation. Then, contaminants in the oxidized film are driven-out under a high temperature heat treatment, thereby to improve quality of the oxidized film, such as durability against a high voltage. Plural capacitors may be formed using oxidized films having a respectively different thickness, by repeating thermal oxidation and removal of the oxidized film.
