In a structure for oil recovery in a compressor for separating oil from refrigerant and supplying the separated oil into the compressor through an oil supply passage, the compressor includes a rotary shaft, a cylinder block having a plural cylinder bores, a cam member rotated integrally with the rotary shaft, a piston received in each cylinder bore being operable in conjunction with the rotation of the rotary shaft through the cam member, a suction port for allowing the refrigerant to be drawn from a suction-pressure region of the compressor to the corresponding cylinder bore, a discharge port for allowing the refrigerant to be discharged from the corresponding cylinder bore to a discharge-pressure region of the compressor, and a flexible reed valve for opening and closing one of the suction port and the discharge port. The oil supply passage is opened and closed in accordance with motion of the reed valve.

After the power supply of a disk drive that uses a head to write data at any position on a disk or read data written at any position is turned on, the first initial conditions for the disk drive that are needed to receive a command from outside and execute the command are determined. The disk drive is then brought to a state in which it can receive the command but the spindle motor is not started. After the disk drive is brought to the state in which it can receive the command, the spindle motor is started and the second initial conditions including all initial conditions other than the first initial conditions are determined. Moreover, a control method for a disk drive that is implemented in the above disk drive is disclosed.

Air conducting connector with simplified wiring layout and water-proofing. Connector 2 has air conduction path 3, having a first opening 3a and a second opening 3b. A heater wire 5, air conducting wire and terminal 6 of ECU side are inserted into the first opening 3a, while an air-conducting heater wire 7 and terminal 8 of sensor side are inserted into second opening 3b. Within the air conduction path 3, the ECU side terminal 6 and the sensor side terminal 8 are electrically interconnected. First opening 3a is sealed with resin. The rear part of the air conduction path 3 is sealed with a sealing material 8b. The sensor side terminal 8 and the ECU side terminal 6 are electrically interconnected on insertion to communicate an air conducting part of the sensor side heater wire 7 with an air conducting part of the ECU side heater wire 5 through air conduction path 3.

A prober which tests an object to be tested under temperature control is provided. This prober includes a stage base, Z stage, X-Y stage having a frame structure, substrate fixing mechanism arranged on the X-Y stage, a probe card arranged to oppose the substrate fixing mechanism, and a probing stage fixed on the Z stage and arranged in the frame structure of the X-Y stage such that its axis coincides with an extension line vertically extending from the probe center of the probe card. The probing stage includes a probing elevating mechanism, and a temperature controller to heat and cool the object to be tested. The probing stage supports the substrate of the object to be tested from the bottom surface, and controls the temperature of the object to be tested.

Compressor are taught that may include a suction port to draw refrigerant and a discharge port to discharge compressed refrigerant. A driving shaft is disposed within a compressor driving chamber. A swash plate is inclinably and slidably coupled to the driving shaft. The swash plate rotates together with the driving shaft at an inclination angle with respect to a plane perpendicular to the rotational axis of the driving shaft. A cylinder bore is disposed adjacent to the compressor driving chamber. A piston is disposed within the cylinder bore and an end portion of the piston is connected to a peripheral edge of the swash plate by a shoe. Preferably, the piston reciprocates within the cylinder bore to compress the refrigerant in response to rotation of the inclined swash plate. A rotor is connected to the driving shaft. A hinge mechanism connects the swash plate with the rotor and transmits torque from the driving shaft to the swash plate regardless of the inclination angle of the swash plate. The hinge mechanism includes a projection disposed on one of the rotor or the swash plate and at least one arm disposed on the other of the rotor or the swash plate. The projection has a recessed structure and at least one arm is coupled to the projection to transmit torque from the driving shaft.

In DRAM divided into plurality of blocks and operating on a block basis, each equalizing circuit is controlled such that release of equalization of an IO line pair is carried out only in a block having a memory cell from which data is to be read for data reading. Since a MOS transistor 40 provided between two IO lines constituting each IO line pair 2 for equalization of these lines and its release is not switched from on to off wastefully, current consumed for charge/discharge of a gate of the MOS transistor is considerably reduced compared to a conventional case.

A semiconductor memory device comprises eight memory arrays (b 10a, 10b) arranged in one column. A peripheral circuit (60) is arranged in the central portion of the eight memory arrays (10a, 10b), two column decoders (51, 52) being arranged with the peripheral circuit (60) interposed therebetween. Each of the eight memory arrays (10a, 10b) is provided with a row decoder (20). A plurality of first column selecting lines (CL1) are provided so as to cross the three memory arrays (10a, 10b) arranged on one side of the peripheral circuit (60) from the column decoder (51). In addition, a plurality of second column selecting lines (CL2) are provided so as to intersect with the three memory arrays (10a, 10b) arranged on the other side of the peripheral circuit (60) from the column decoder (52).
摘要:
In a relaying apparatus, a label information controller generates and transmits label information including at least one of communication medium information on communication media for use in communication with other apparatuses and communication cost information on communication costs that are generated when communication is performed via the relaying apparatus. In a communication apparatus, a route controller receives the label information, creates a list of routes for use in communication with a communication counterpart, and detects a communication route through which communication is to be performed from the list. The route controller creates a list of all routes including, out of relaying apparatuses, relaying apparatuses which enable communication with a counterpart apparatus using a communication medium which the communication apparatus has, and based on the communication cost information included in the label information, detects a communication route which is lowest in communication costs from the list.
摘要:
Three-dimensional microstereolithographic objects fabricated by microstereolithography are exposed to UV light for one hour to accelerate hardening. The structures are then heated at 175° C. or above for at least 6 hours. The heating temperature may exceed the glass transition temperature, which is the index of thermal softening temperature of materials. The present invention relates to three-dimensional microstructures formed by microstereolithography. Deformation due to a structure's own weight, which generally poses a problem in heat treatment, is reduced with microstructures due to the size effect. As a result, the dimensions of the three-dimensional structure fabricated by the present invention remain almost unchanged before and after the heat treatment.
