Abstract: PURPOSE:To measure an accurate moving distance by detecting the diffracted light caused by laser light projected on the scale through a lens, a plurality of  light receiving elements, and the optical scale which are arranged so as to  satisfy a specified relationship. CONSTITUTION:The luminous flux from a laser diode 1 is converged by a lens L1 and further converged by a lens L2 and projected on the scale 2 having a scale grid with an equal interval.

Its outputs are inputted to a control circuit 4. A moving distance signal PA and a moving direction signal PB are sent to a display 5. With the center of the lens L2 as an original point, the equation H=fYd/(f-Yd) is satisfied, where (f) is the focal length of the lens L2, Yd is the Y coordinate of a light receiving surface, H is the image position of the projected light, and (h) is the Y coordinate of the reflecting surface of the scale 2. Since the pitch of interference fringes is not related to an operating distance (h), the accurate moving distance is measured.

IPC: G11B7/30
Filed: 1988-03-31
Abstract: PURPOSE:To perform a crystallizing recording wide to a groove width and to obtain a high-quality signal by offsetting the operating point of a focus from a position in focus and changing a crystallizing laser beam profile and an amorphous laser beam profile. CONSTITUTION:The sigmoidal characteristic of focus control is a normal focus range 14, a normal operating point or a position in focus 15 and an offset position 16 in the case of this crystallizing recording. At the time of the normal crystallizing recording is a profile 6 and a B point is the critical temperature of crystallization. When the operating point of the focus is selected at the point shown by the 16, the laser beam becomes wider than the case in focus, the highest value of laser power lowers and it becomes a profile shown by a code 17. That is to say, a range in which the crystallization occurs widens from a conventional range shown by a code 8 to a range shown by a code 18. Thus, the crystallizing recording wide to the groove width can be performed and the high-quality signal can be obtained.

Title: Bottom plate immobilizing device for semiplastic material cutting bed
Inventor: MIYAUCHI MASAMICHI
IPC: B28B11/14
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent a bottom plate form being shifted out of plate and also cracks from developing in a semiplastic material after cutting by fixing striplike bottom plates, in a freely attachable/detachable manner, which are aligned side by side in the longitudinal direction of a semiplastic material cutting machine and are disposed on the upper faces of individually ascendable/descendable cutting beds. SOLUTION: Electromagnets 12 are perpendicularly mounted at positions opposed to each other from the center, on the body of a cutting bed 2, the magnetic poles being protruded from the upper faces of cutting beds 2 upward. In addition, springs are arranged below the electromagnets 12 so that the electromagnets 12 are always urged upward. When moving a molding frame for holding bottom plates to a position above the cutting beds 2 and making the frame descend, the back faces of the bottom plates come into contact with the magnetic poles and supporting bolts 8 whose height is previously adjusted bear the bottom plates so that the back faces of the bottom plates are brought into contact closely with the magnetic poles.  Under this state, the electromagnets 12 are energized to magnetically attract the bottom plates to the magnetic poles strongly and firmly hold the bottom plates to the upper faces of the cutting beds 2 without being deviated out of place. In addition, the bottom face of the semiplastic material is uniformly retained when the semiplastic material to be placed on each of the bottom plates is cut. Thus it is possible to prevent the bottom plates from being deviated out of place, thereby cracks from developing in the semiplastic material after cutting.
