摘要:
A bonding apparatus such as a die bonding apparatus in which a bonding tool at one end of an ultrasonic horn is given a vibration, the bonding apparatus being equipped with a Y-direction driver which has a Y-direction piezo-electric element that causes the bonding tool to vibrate in a Y-direction which is parallel to an axis of the ultrasonic horn, and an X-direction driver which has an X-direction piezo-electric element that causes the bonding tool to vibrate in an X direction which is on a plane perpendicular to the Y-direction, so that the piezo-electric elements are driven during bonding so that the bonding tool vibrates in the X- and Y-directions on the bonding plane.

A liquid crystal device used for electro-optical devices, in which each parameter of the liquid crystal having layer structures is specified to provide a liquid crystal high in stress resistance and capable of gray scale display. The liquid crystal held between a pair of parallel substrates is either ferroelectric or antiferroelectric and represents layer structures. A plurality of substrate interface tilt angles can be set for the layer structures. The layer structures can be configured asymmetric or symmetric about a plane intermediate between the parallel substrates. With this configuration, a liquid crystal device is constructed having a plurality of layer structures including at least one layer structure, which has (1) a substrate interface layer tilt angle of 0.degree. to 3.degree. and the c director pretilt of 3.degree. to 5.degree., or (2) a substrate interface layer tilt angle of 4.degree. to 7.degree. and the c director pretilt of 0.degree. to 3.degree., or (3) a substrate interface layer tilt angle of 8.degree. to 20 .degree. and the c director pretilt of 9.degree. to 90.degree. or less.

An automotive radiator cooling system has a radiator cooling fan driven by a hydraulic motor actuated by a pressurized fluid fed through a hydraulic circuit from an engine-driven hydraulic pump. A bypass line extends in bypassing relationship to the hydraulic motor and has ends connected to the circuit upstream and downstream of the hydraulic motor, respectively. A check valve is provided in the bypass line and is operative to allow a flow of the fluid from a reservoir through the bypass line back into a part of the circuit upstream of the motor only when a pressure drop takes place in that part of the circuit due to free rotation of the cooling fan, and thus of the motor, independently of the drive by the hydraulic pump. The backward flow of the fluid is operative to compensate for the pressure drop to prevent the occurrence of cavitation in the circuit upstream of the motor. Desirably, the bypass line is incorporated into the housing of the hydraulic motor.

A compressor has suction reed valves each of which includes a fixation portion fixed to the valve base plate, a basal portion that extends from the fixation portion and is separable from the plate, and a valve flap extending from the basal portion toward the distal end to selectively open and close the suction port. Each suction port has a shape elongated in the width direction, which is orthogonal to the longitudinal direction. The width of the basal portion is greater than that of the suction port. Each valve flap includes an opening-closing portion facing the corresponding suction port and stoppers, which project from the ends in the width direction. The side edges in the width direction are continuous from the stoppers to the basal portion to gradually approach the suction port. The cylinder block has pairs of recessed retainers. The stoppers contact the retainers.

A device for generating a sterilizing gas includes a methanol gas generation device (11) for vaporizing methanol to generate a methanol gas, a tubular part (12) and a catalyst section (13). The tubular section (12) is arranged on top of the methanol gas generation device (11) to provide a flow path for upwardly directing the methanol gas generated by the methanol gas generation device by natural convection. The tubular section also operates to mix the methanol gas with a predetermined proportion of air. The catalyst section (13) is arranged on top of the tubular section (12) for turning the methanol gas mixed with the air at the predetermined proportion in the tubular section (12) into radicals by a catalyzed reaction. The catalyst section (13) is formed by a turn-into-radical reaction catalyst layer (30) obtained on forming a thin metal sheet (35a) to a honeycomb structure.

The present invention provides a production process for obtaining a pad base for endermism capable of administering a drug in the skin without vibration. One side end of a thin metal wire is immersed in a solution containing a synthetic resin raw material in a lengthwise direction, the synthetic resin raw material solution adheres to a periphery of the thin metal wire, the synthetic resin raw material solution is hardened and then the thin metal wire is pulled out. The resulting minute needle is a hollow tubular body and the outer wall thereof is thickened toward the bottom. The minute needle is installed upright on the skin side of a patch base, and a drug in the hollow portion of the minute needle is injected in the skin and can be provided for endermism.

According to a conventional MicroPatch method, a drug is administrated by stinging the skin with a solid-core needle, and broadening a gap between the needle and the skin by vibration with a vibrator. Consequently, the object of the present invention is to provide a pad base for endermism capable of administrating a drug in the skin without vibration, and to provide a production process capable of easily obtaining the pad base. One side end of the thin metal wire is immersed in a solution containing a synthetic resin raw material in a lengthwise direction, the synthetic resin raw material solution adheres to a periphery of the thin metal wire, the synthetic resin raw material solution is hardened and then the thin metal wire is pulled out. There is obtained the minute needle 1 which is installed upright on the skin side of a patch base 2, wherein the minute needle is a hollow tubular body and the outer wall thereof is thickened toward the bottom. A drug in the hollow portion 3 of the minute needle 1 is injected in the skin and can be provided for endermism. Further, since the minute needle 1 spreads and is thickened toward the bottom, it hardly fractures.

A low-cost vehicle air-conditioning apparatus for idle stopping vehicles is capable of performing both cooling and heating operations throughout the year. The air-conditioning apparatus includes an engine-driven compressor and engine-driven pump for a heating unit. The air-conditioning apparatus includes a motor-driven compressor and pump. A control unit drives the motor such that the motor-driven compressor is operated when there is a need for cooling and the motor-driven pump is operated when there is a need for heating when the engine is stopped. Battery power is conserved through various methods.
