  • Patent number: 7481635
    Abstract: A compressor having a compression element with a cylinder in which a compression space is constituted, a suction port and a discharge port which communicate with the compression space in the cylinder, a support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber.

  • Patent number: 6893237
    Abstract: There is provided a horizontal rotary compressor capable of improving performance thereof while an oil supply means smoothly supplies oil. A part of a hermetic shell case at the upper side is partitioned by a baffle into an electric element side and an oil pump side, a refrigerant which is drawn from an outside of the hermetic shell case is compressed by a first rotary compression element and a second rotary compression element and discharged toward the electric element side of the baffle, then it is further discharged from oil pump side toward the outside of the hermetic shell case. The baffle closes a flow path area of the refrigerant over an oil level inside the hermetic shell case at a ratio ranging from not less than 50% to not more than 80% during the stoppage of the horizontal rotary compressor.

  • Patent number: 6722486
    Abstract: The bill input/output part has a movable pusher plate and a front plate and a partition plate movable between the pusher plate and the front plate to store bills, which are to be returned or paid, between the pusher plate and the partition plate, and also includes a controller to vary the distance between the pusher plate and the partition plate according to the number of bills to be stored. Bills can be arranged upright. After the bills stored between the pusher plate and the partition plate are extracted, the distance between the partition plate and the front plate is widened. This operation makes it easy to re-enter bills in the space. When a remaining bill, such as a folded bill is detected, the space between the pusher plate and the partition plate is widened so that the user can easily be notified of a failure to extract.

  • Patent number: 6435850
    Abstract: A rotary compressor uses a freon without containing chlorine ions and uses polyol ester as a lubricant or plyvinyl ether as a base oil for providing a highly reliable rotary compressor, and for preventing abnormal abrasion. The rotary compressor has a roller and a vane sliding contact with an outer cirumference of the roller. A sliding contact portion between the vane and the roller is formed with a radius of curvature Rv, and satisfies T<Rv<Rr, wherein T is the thickness of the vane and Rr is the radius of curvature of the outer circumference of the roller.
