Patent number: 6080358Abstract: There is disclosed a method for forming compacts having a hole extending along a direction crossing the compressing direction. In the method, a powder or a pre-compressed compact and a core for forming a hole are assembled in a cavity. The core and a die are set in a condition that the core can move in the compressing direction. The punch compresses the powder and forms a compact. The core does not engage with the die, whereby the core is not exerted with load. Therefore, the method does not need control of compressing for avoiding exertion of load on the core, and can prevent transformation or break of the core. The compact in which the core is inserted is drawn out from the die, so that damages such as break or crumble of the compact is prevented in drawing out.Type: GrantFiled: December 18, 1998Date of Patent: June 27, 2000Assignee: Hitachi Powdered Metals Co., Ltd.Inventors: Takeshi Oba, Yoshimi Sugaya

Patent number: 5430547Abstract: A non-contacting position detecting apparatus includes a laser unit having a light emitting portion and a light receiving portion for irradiating laser light upon a detection point of a subject for measurement and receiving laser light reflected from the detection point to recognize the distance to the detection point. An arm is capable of moving the laser unit in the direction of at least one axis of a rectangular coordinate system. A coordinate detecting member is provided for detecting coordinates of the arm. Coordinates of the detection point are recognized in accordance with the coordinates of the arm when the positional relationship between the detection point and the laser unit reaches a predetermined relationship.Type: GrantFiled: February 8, 1993Date of Patent: July 4, 1995Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kiyoshi Takagi, Toshio Kurihara, Shoichi Kuwahata, Kazuo Ohomori, Atsumi Toyama, Takeshi Oba

Patent number: 5405299Abstract: A toothed belt and belt-adapted pulley system provides a high-load capacity and increased durability by reducing stress concentrations on dedendum portions and further preventing localized bending of belt tensile cords. Smooth engagement of elastic teeth of a belt is possible due to minimization of interference between the elastic teeth upon engagement or disengagement with a pulley. Reduced vibration, low noise, and a reduction in skipping under high loads result from the inventive system. Each tooth of the belt has a peripheral length m.sub.0 and a dedendum portion with a length m.sub.1, where m.sub.1 /m.sub.0 is 0.1 or less. Each tooth of the pulley has a peripheral length n.sub.0 and a dedendum portion having a length n.sub.1, where n.sub.1 /n.sub.0 is 0.1 or less.Type: GrantFiled: December 17, 1993Date of Patent: April 11, 1995Assignee: Bridgestone CorporationInventors: Takaharu Kubo, Reiji Sato, Takeshi Oba, Akira Nakaegawa, Yoshihide Fukahori
