Abstract: PURPOSE:To derive a position of an optical head by non-contact, without causing a change with the lapse of time, and with a high accuracy and a good responsiveness by providing a light source which has been placed on a moving body, the first - the third optical systems, and a photoelectric detector which is placed at a fixed position, and detects an irradiated position of a parallel luminous flux which has been emitted from the moving body. CONSTITUTION:A light which has transmitted through a beam splitter 10 is curved by an optical system for curving it so that its advance direction makes a prescribed angle against the moving direction of an optical head 3, namely, a prism 11, and made incident on the lower end of a photoelectric detector 4. When the optical head 3 moves to the inside peripheral part of an optical disk 1, the parallel luminous flux which has been curved by the prism 11 moves from a position 23 to a position 24, and the incident position is varied on the photoelectric detector 4. Accordingly, by detecting the incident position of the parallel luminous flux 23 or 24 on the photoelectric detector 4, a position of the optical head 3 can be detected. As for the photoelectric detector 4, a semiconductor position detecting element of a non-split type by which a photocurrent obtained from both ends of the element is varied by the incident position of a light, or a photodetector of a split type can be used.

Title: Manufacture of wide metallic clad plate
Inventor: TAKEHARA SHIROSHI
IPC: B23K20/08
Filed: 1978-05-19
Abstract: PURPOSE: To restrict the generation of the defective alloy layer, and to inexpensively manufacture  the explosively clad plate, by initiating the explosion from the point, offset from the weld line, at  approximate middle of the clad metal, so as to make the weld line of the clad metal to be approximately parallel to the direction of the explosive cladding of the clad metal onto the parent  metal.  
     CONSTITUTION: The explosion initiating point 3, in case of use of the clad metal 1 including the  weld line 2 longer than 1500mm, is 5W20mm offset from the middle point of the weld line 2  toward the wider area side of the unwelded portion; and the explosion is initiated from this point  3. Even if the explosion is initiated from the point other than above stated explosion initiating  point 3, the explosive cladding is possible, however, the point 3 is favorable, and the initiation of  explosion at a point on the weld line 2 ought to be avoided. In the method of this invention, the  weld line longer than 1500mm in the clad metal is approximately parallel to the direction of  detonation of explosives, and the explosion must be initiated from the unwelded zone, a little offsetting from the weld line; hereupon, about 5W20mm offset is favorable. When the string type  explosives is not used, the distance between weld lines longer than 1500mm is limited under  approximate 500mm, preferably under 300mm.
