摘要： In an engine idle speed control system associated with an air conditioner provided with an evaporator for evaporating a refrigerant compressed by a compressor actuated or deactuated by an engine near an evaporator freeze limit temperature, the engine idle speed is increased under consideration of thermal load applied to the compressor whenever the compressor is being actuated. The compressor 21 is deactuated when the temperature of air having passed through the evaporator 22 drops below a predetermined value, and actuated when the same temperature rises beyond another higher predetermined value. Whenever the compressor 21 has been deactuated, the time interval between the deactuation and the actuation of the compressor is measured. If the measured time interval is relatively short, since this indicates a relatively high thermal load applied to the compressor, the engine idle speed is increased. However, if the measured time interval is relatively long, since this indicates a relatively low thermal load, the engine idle speed is not increased, thus improving the fuel consumption rate and the compressor durability without frequently actuating and deactuating the compressor.

摘要： This disclosure relates to an improved method for driving a hand-piece of the air drive type to improve its cutting performance, and to increase its cutting load in a low range of rotational speed in particular, and also relates to a device for practicing the method. The disclosed method employs compressed high-velocity fluid exhausted to one side of an annular space in which blades rotate after having once been jetted at said blade guided along the rotating direction of said blades and then causing it to reenter the annular space in a diagonal direction with respect to the rotational direction of the blades for further driving the running blades in the same sense. The device includes a simply machined ring-shaped adapter.

摘要： A volumetric fluid compressor or a so-called scroll type compressor is provided in which a rotary shaft is placed centrally in the front side of a housing, a helical portion of a movable scroll member is contacted eccentrically with a helical portion of a fixed scroll member, the helical portion of the movable scroll member is rotated about the axis of the rotary shaft to which the movable scroll member is mounted with an offset, in such a manner that a closed space defined between the two helical portions may be contracted towards the center for compressing the refrigerant gas which may thus be discharged towards rear from the center of the fixed scroll member. A stationary member for preventing the rotation of movable scroll member is secured in the housing about centrally of the longitudinal axis of the housing for defining a suction chamber towards the front side of the housing and a working chamber on the rear side of the housing, the fixed and movable scroll members being provided within the working chamber. A suction port is formed in the housing directly above the rotary shaft for introducing the fluid to be compressed into the suction chamber whereas a plurality of suction passageways are formed in the stationary ring for introducing the fluid to be compressed from the forward side suction chamber into the rear side working chamber.

摘要： A air-driven cutting device for medical treatment (a handpiece (10)) comprises a housing (18) for a head portion (14). The housing (18) accommodates a rotary cylinder (60) for holding a cylindrical cutting tool (46) inserted through the tool inlet (42) of the housing, and a turbine blade (62) mounted around and secured on the rotary cylinder. With this arrangement, a compressed air is blown onto the turbine blade to rotate the turbine blade, the rotor and the cutting tool. Particularly, a part or a whole of the end portion of the rotary cylinder in the vicinity of the tool inlet is covered with the cover section (42) of the housing. Therefore, the rotary cylinder does not contact the teeth or the tissues of the buccal cavity.
