摘要： PROBLEM TO BE SOLVED: To provide a copper alloy which has excellent thermal conductivity equal to that of conventionally used materials and also has thermal expansion coefficient lower than that of copper and can be manufactured at a low cost.
SOLUTION: A base material, such as oxygen-free copper and Cu-B alloy, is melted in vacuum by a high-frequency melting method. Then, B, Mg, Ni, Co, Al, Si, Fe, Zr and/or Mn is added, in the form of a simple substance or an alloy of Ni-B, Fe-B, Cu-Mg, etc., to the resultant molten metal so that prescribed contents are attained. The molten metal is cast into an ingot in the shape of a square 12 mm on a side, heated at 600 to 900°C for 1 h and then rolled to 3 mm by hot rolling. Subsequently, heat treatment is performed at 600 to 900°C and then working is applied into prescribed shape.

摘要： PURPOSE:To provide a valve hole closing plug for an aluminum road wheel remarkably improved in the durability of the plug with only one time being sufficient in the cleaning process, and also provide the leakage detecting method thereof. CONSTITUTION:A valve closing plug for an aluminum road wheel has a plug body 1 with at least an one-end closed expansion part 2 formed of rubber; a cylindrical metal stem 5 with one end part inserted into the open end side of the plug body 1 and with the inside thereof made into an air passage; a sleeve 8 fitted to the outer periphery of the exposed part of the stem 5; and a spindle 13 fitted into the stem 5. The spindle 13 is inserted through a supporting member 10 fixed being thrustd into the stem 5, and moved in the axial direction. When this spindle 13 moves onto the expansion part 2 side, a collar part 14 fixed to the spindle 13 also moves along the inner surface of the stem 5 onto the air chamber 3 side. Air in the stem 5 is thereby pressed into the air chamber 3 so as to expand the expansion part 2. The plug is thereby fixed airtightly to a valve hole.

摘要： PROBLEM TO BE SOLVED: To suppress generation of material losses and reduce costs of manufacturing of a sensor rotor by fixing at the inside of a press-in ring a magnetized ring alternately magnetized with different poles in a circumferential direction of a ring body obtained by molding a band-shaped plate of a predetermined length of magnetic material into a ring. SOLUTION: A long band-shaped plate 1 formed of magnetic material is wound in a coil so that side edges are faced inside and outside, thereby forming a coil body A. Divided rings 2 are turned flat so that cut end faces perfectly butt and match with each other. The cut end faces are bonded by welding or the like manner, thereby forming a ring body. Thereafter, magnetic poles N, S, N, S,... are alternately magnetized in a circumferential direction of a front and a rear faces of the ring body, whereby a magnetized ring 3 is obtained. The magnetized ring 3 is fixed to an inner face of an inward flange of a press-in ring by welding, etc., thereby forming a sensor rotor R. When the ring body is formed, the divided rings 2 may be flattened in a state that end faces are separated from each other.
