    Abstract: The variable displacement swash plate compressor includes a housing, a drive shaft, a swash plate, a piston, a bleed passage, a supply passage and a low-melting member. The housing has a cylinder bore, a suction chamber, a discharge chamber and a crank chamber. The swash plate is supported in the crank chamber by the drive shaft and inclination angle of the swash plate is adjustable. The piston is reciprocally movably received in the cylinder bore. The bleed passage is formed in the housing in communication with the crank chamber and the suction chamber. The supply passage is formed in the housing in communication with the discharge chamber and the crank chamber. The low-melting member is disposed in the bleed passage so as to restrict fluid flow therethrough and has a lower melting point than the housing. When the low-melting member is melted, an opening of the bleed passage is increased.

  • Patent number: 7841840
    Abstract: A mechanism for drawing in refrigerant to front compression chambers (28a) of a double-headed piston type compressor differs from a mechanism for drawing in refrigerant to rear compression chambers (29a). More specifically, the mechanism for drawing in refrigerant to the front compression chambers (28a) include suction valves (18a) configured by flap valves. The mechanism for drawing in refrigerant to the rear compression chambers (29a) is configured by a rotary valve (35). Thus, pulsation of the compressor is reduced, so that the generation of noise is suppressed. As a result, a quiet compressor is achieved.

    Abstract: A system used to detect and assay genes by using a nucleic-acid probe substrate is disclosed, which can be used in highly general-purpose genetic chips usable for various purposes, and has a temperature control means enabling control of temperature of the whole genetic chip in a high reproducibility and uniformity, and further even satisfies low-cost performance. A method for detecting and assaying gene nucleic acids by using such a system is also disclosed. A heat-conductive material made up using a material having good thermal conductivity, having a shape having general-purpose properties, is used as the temperature control means, and is disposed in such a form that it covers substantially the whole substrate face or stands in contact therewith, on the back of the substrate, or on the side facing the surface to which the detecting single-stranded nucleic acid fragments have been immobilized. This makes it possible to improve the diffusion of heat in the in-plane direction of the whole substrate face.
