摘要： A joining alloy of the invention is based on Co, Ni, or their alloy, and contains 1.0 to 2.3% by mass of C and 15.5 to 34.7% by mass of W. Using HIP, the joining alloy in the form of a casting or powders is integrated with a WC--Co or WC--Ni type cemented carbide via diffusion joining. Using HIP, it is also possible to obtain a composite material having an integral structure in which a cemented carbide and the joining alloy, and the joining alloy and steel are joined together via diffusion joining. The joining alloy may additionally contain up to 30% by mass of Fe, up to 3% by mass of Si and up to 3% by mass of Mn as well as up to 10% by mass of at least one selected from Cr, Mo, V, Nb, Ti, Zr, and Ta. It is thus possible to obtain a joining alloy having an improved joining strength without producing a brittle phase therein even upon joined to the WC--Co or WC--Ni type cemented carbide, and its composite material.

摘要： A hollow steering shaft having a good quality can be manufactured at a low cost by passing a blank tube having a circular cross section through a preliminary shaping die and then through a finishing shaping die. The blank tube which has passed through the preliminary shaping die is formed with two kinds of convex curve surface portions having different radii of curvature and arranged continuously, circumferentially and alternately. When the blank tube passes through the finishing shaping die, the larger convex curve surface portions are deformed into flat portions. As a result, a steering shaft having an elliptical cross section is manufactured.

摘要： A variable displacement vane compressor for an air conditioning system used in an automobile has a cylinder assembly having a bore which receives a rotor to form at least one crescent or compressing chamber between the rotor and the bore. The crescent chamber receives a refrigerant which is returned from the air conditioning system. The rotor has vanes which are extendably fitted therein so that the free end of the vanes are in contact with the circumferential inner surface of the bore during the rotation of the rotor, whereby when the vane passes through the crescent chamber, the refrigerant received therein can be compressed. The amount of the refrigerant introduced into the crescent chamber is adjustable in response to a change of a cooling load at the air conditioning system.

摘要： A variable capacity type vane compressor comprising a cylinder having an oblong cylinder bore and a rotor with radial vanes rotatably inserted in the cylinder so that the radially outer ends of the vanes are in slidable contact with the cylinder bore surface to form compression chambers therebetween. A movable capacity control disk is arranged at an interface between one side plate and the rotor to control the quantity of introduced gas and/or returned compressed gas to vary a capacity of the compressor. The capacity control disk is moved by a spool actuator inserted in a spool cylinder having opposed working chambers. Gas under output pressure is introduced into the first working chamber, and oil under output pressure is introduced into the second working chamber, while a leak passage relieves the oil pressure to an intermediate pressure. A spring is also arranged in the second working chamber to urge the spool, and a valve is arranged in the oil passage close to the second working chamber to regulate the movement of the spool in response to a predetermined requirement.

摘要： A variable-delivery compressor having plural compression chambers whose volume is changed as a rotor is rotated in a housing to compress a gas sucked through a suction port and deliver the compressed gas through a discharge port, comprising: a by-pass passage for communication between a compressing and a sucking compression chamber of the plural compression chambers; a device for changing the position of the discharge-side extremity of an opening of the by-pass passage on the side of the compressing compression chamber, in the circumferential direction of the rotor, to retard the compression start timing of the compressing compression chamber; and at least one of a variable flow restrictor device associated with a suction passage communicating with the suction port to adjust a flow of the gas which is sucked through the suction passage, and a pressure relief device including a pressure relief passage and a switching device for closing and opening the pressure relief device. The pressure relief passage is normally closed by the switching device, but opened by the switching device to permit the compressing compression chamber to communicate with the suction chamber when the discharge-side extremity of the opening of the by-pass passage is shifted in the rotating direction of the rotor to a position nearest to the discharge port.
