Title: Optical digital disc player
Inventor: NABESHIMA DAIKI
IPC: G11B7/00
Filed: 1982-04-30
Abstract: PURPOSE:To obtain an excellent disc player which compensates dropout sufficiently, by predicting the position of a disc having dropout in advance, and decreasing the open loop gain of a tracking control system. CONSTITUTION:When the 1st dropout is detected, a level comparator 26 inverts the level of an output terminal. Since the output signal of the level comparator 26 is delayed at a delay circuit 41 for a period required for about one revolution of the disc 11, switching circuit 35 and 40 are driven when the next dropout is produced, allowing to produce a signal applied to a terminal (b) respectively. As a result, the time when the next dropout is produced is predicted to bring each open loop gain of the focus and the tracking control system into a low level for a prescribed period for the dropout compensation.

Title: Groove former for broadside splitting of slab
Inventor: NAKAMURA KATSUMI
IPC: B22D11/126
Filed: 1980-06-03
Abstract: PURPOSE: To miniaturize a titled device and form deep grooves without being restricted structurally by pressing an oscillatable bladelike body having a convex  curved blade edge part onto th surface of a slab thereby forming a groove.  
     CONSTITUTION: When a driving shaft 17a is moved forward and backward by operating a driving device 16, a lever 15 oscillates around a shaft 19 while its long hole 15 a is slipping with the shaft 19, in accordance with which a bladelike body 8 oscillates around a fulcrum shaft 10, thereby shearing the surface of a slab 5 longitudinally. Here, the distance L from the fulcrum shaft 18 at the lever 15 up to a fulcrum (shaft 19) is set considerably larger than the distance from the fulcrum up to the fulcrum shaft 16. Hence, the force exerted upon the body 8 is made exceedingly larger by the lever action of the lever 15 than the force exerted upon the driving device 17, and this permits the use of the device 17 of a relatively small size.
