摘要： Provided is a piston ring with a sprayed coating which exhibits excellent wear resistance and scuff resistance and makes little attack against a mating member. Specifically provided is a piston ring which has, on the sliding surface, a sprayed coating formed by thermally spraying a mixed powder comprising an Mo powder, an Ni-base self-fluxing alloy powder, and a Cu or Cu-alloy powder as the essential components. The sprayed coating comprises, as the essential components, 50 to 80mass% of Mo, 1 to 12mass% of Cu or a Cu alloy, with the balance being an Ni-base self-fluxing alloy, and the area fraction of the Cu or Cu-alloy phase appearing on the sliding surface of the sprayed coating falls with the range of 0.5 to 15%.

摘要： A component (14) of a material which is different from that of a shaft (12) is firmly attached to one end of the shaft (12). The component (14) is provided with an axial projection (15) corresponding to a recess (13) formed in the outer peripheral surface of the shaft (12), and a hold (16) is formed in the projection (15) to receive a retainer member (17). The retainer member (17) enables the retention of a component (20) such as a pulley or the like, so that the component (20) does not rotate about the shaft (12).

摘要： A fluid-support apparatus supports a rotational sleeve (30) of a vaned rotary compressor which is provided with the rotational sleeve (30) which rotates together with vanes (16), making use of the air-bearing effect of an air-bearing chamber (40) formed between the inner peripheral surface of a center housing (22) and the outer peripheral surface of the rotational sleeve (30). The air-bearing chamber is supplied with discharge-pressure air from a discharge chamber (41) or maximum-pressure air from a maximum-pressure operating chamber (43). Guide grooves (74) are cut either partially or completely around both end portions of either or both of the inner peripheral surface of the center housing and the outer peripheral surface of the rotational sleeve. Accordingly, the air supplied to the air-bearing chamber flows into the guide grooves and increases the load-bearing capacity of the bearing, so that the portions of the air-bearing chamber at either axial end thereof have a uniformly increased load-bearing capacity.

摘要： A cam shaft (10) is composed of components such as a hollow shaft (11) and a cam lobe (12) or other component made of a sintered alloy. The hollow part of the shaft (11) defines a lubricating oil passage, and lubricating oils is supplied to the peripheral surface of the cam lobe (12) through radial oil holes (13), (14) provided in the shaft (11) and the cam lobe (12), respectively. Either the oil hole (13) in the shaft (11) or the oil hole (14) in the cam lobe (12) is formed so that it is larger than the other hole, to ensure that the oil holes (13), (14) will not be blocked even if there is a slight positioning error when the cam lobe (12), or other component, is secured directly to the shaft (11) by liquid-phase sintering.

摘要： The present invention addresses the problem of providing a piston ring having a hard carbon film exhibiting exceptional wear resistance and initial conformability, and a manufacturing method therefor. This problem is solved by a piston ring (10) having a hard carbon film (4) formed on at least an external peripheral sliding surface (11) of a piston ring base material (1), the hard carbon film (4) having a sp2 component ratio within a range of 40% to 80% inclusive as measured by a TEM-EELS spectrum which combines electron energy loss spectroscopy (EELS) with a transmission electron microscope (TEM), the hydrogen content being in a range of 0.1 at.% to 5 at.% inclusive, and the amount of macroparticles appearing on the surface being in a range of 0.1% to 10% inclusive by area ratio. The hard carbon film (4) is formed on a hard carbon foundation film (3) formed under low-speed film-forming conditions on the side of the piston ring base material (1), and the hard carbon foundation film (3) is formed with an arc current value 80% or less of the arc current value during the formation of the hard carbon film (4).

摘要： A cam shaft is formed by molding thereonto a green compact which will form an assembly component (20) made of a sintered alloy when subjected to liquid-phase sintering. Since notches (22) are formed in both side surface portions of the green compact which have a higher density than the central portion thereof, bending of the outer peripheral surface of the green compact caused by the liquid-phase sintering is evened out to ensure that the outer peripheral surface remains smooth.

摘要： A rotary compressor is provided with a rotary sleeve (30) and vanes (16). The sleeve is supported by a pneumatic thin bearing chamber (40) formed between the outer peripheral surface of the sleeve and the inner peripheral surface of a central housing (22). The air in a discharge chamber or a discharge-side working chamber (43) is introduced into the pneumatic bearing chamber through an inlet (71). Since a pocket (73) is cut in the inner peripheral surface of the central housing, the pneumatic bearing chamber has a high load-bearing capacity, and it is also possible to prevent scuffing between the sleeve and the central housing.
