    摘要: The present invention provides a refrigeration or heating system which includes a high pressure gaseous refrigerant bypass which introduces high pressure gaseous refrigerant to the compressor through a hole therein. This reintroduction of high pressure gaseous refrigerant increases the work capacity of the compressor, which is particularly valuable in the heating mode where the ambient temperature is low, and also hastens the pressure rising characteristics of the compressor. A low pressure gaseous refrigerant bypass to the compressor may also be provided for permitting a portion of the compressed refrigerant in the compressor to be discharged, thereby reducing the danger of overheating of the compressor. A further feature of the invention is the introduction of low enthalpy refrigerant into the compressor which will also cool an overheated compressor. Appropriate control means are provided for controlling the flow of refrigerant through the bypasses.

    摘要: A semiconductor device comprises a semiconductor substrate and at least one supporting electrode soldered to one surface of the semiconductor substrate. The supporting electrode is constituted by a composite body having fibers embedded in a matrix of an electrically conductive metal. The coefficient of the thermal expansion of the fibers is substantially equal to or smaller than that of the semiconductor substrate. The fiber is arrayed in an annular, circular, spiral or the like pattern at least in the surface portion of the composite body on which the composite body is bonded to the substrate.

    摘要: To provide a gas compressor in which saving of power as well as improved compression performance and durability are attained by enabling reduction of vane back pressure without degrading the projectability of the vanes upon starting operation of the compressor. Scoop grooves and a high pressure supply hole are arranged so as to be spaced apart from each other, and the interval therebetween is set to an interval sufficient to ensure that a vane groove is communicated with neither the scoop grooves nor the high pressure supply hole while the vane groove moves apart from the scoop grooves toward the high pressure supply hole. Further, if there has occurred a reversed pressure relationship between a suction chamber (low-pressure chamber) and a discharge chamber (high-pressure chamber), a pressure control valve is actuated upon starting operation of the compressor to interconnect the scoop groove with the suction chamber side.
