  • Patent number: 10101073
    Abstract: A drug refrigerator capable of temperature control with a small fluctuation range in interior temperature is provided. This is the drug refrigerator in which cold air in a cooling chamber partitioned by a vertical partition plate in the back of an interior is circulated into the interior by a fan. A cold air inlet is formed above the center of the vertical partition plate. At right and left positions lower than a cooler in the cooling chamber, forward-facing cold air outlets are provided. A downward-facing cold air outlet for blowing out cold air toward a bottom part of the interior is provided at a position lower than the forward-facing cold air outlets. The circulation amount of cold air blown out through the forward-facing cold air outlet is made larger than the circulation amount of cold air blown out through the downward-facing cold air outlet.

  • Publication number: 20180045434
    Abstract: A refrigeration device includes: a refrigerant circuit in which a compressor, a condenser, a decompressor, and an evaporator are connected circularly in the stated order; and a regenerative refrigerator including a heat dissipation portion that compresses a working fluid enclosed in a chamber and dissipates heat produced by compression, and a heat absorption portion in which the working fluid compressed in the heat dissipation portion is expanded. A refrigerant in the condenser is cooled by heat exchange between the condenser and the heat absorption portion.

  • Patent number: 5947766
    Abstract: A fitting structure for a connector housing can maintain a stable vibration absorbing function. A flange (14) of a connector housing (10) is provided on the periphery with an outer annular retaining wall (15). A rubber sheet (20) is contained in an interior of the connector housing (10). The connector housing (10) is attached to a body (E) of an engine by means of bolts (B) and nuts (N). When fattening bolts (B) and nuts (N), the rubber sheet (20) is compressed. In a conventional fitting structure, the compressed rubber sheet (20) expands laterally to bulge out of the flange (14). Since the outer annular retaining wall (15), however, serves to limit the lateral expansion of the rubber sheet (20) so that the rubber sheet (20) does not bulge out from the flange (14), it is possible to prevent the rubber sheet (20) from changing its physical and/or chemical nature and to effectively maintain its vibration absorbing function.
