Abstract: 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. The laser unit includes a needle-like indicating member for indicating the crossing point between extension lines of an optic axis of laser light radiated from the light emitting portion and an optic axis of laser light received by the light receiving portion when the detection point and the laser unit reach the predetermined positional relationship.

Abstract: 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.
