Title: Disk record reproducing device
Inventor: NAKAMURA SHINICHI
IPC: G11B21/08
Filed: 1982-11-08
Abstract: PURPOSE:To enable exact retrieval of desired address by providing a device that makes a tracking control system off and makes track jumping by a kick pulse having pulse of positive negative polarity and determining the pulse width of positive negative polarity by number of jumped tracks. CONSTITUTION:Number of tracks jumped by a light beam is made twice the maximum countable value N of the first and second counting circuits 33, 34. If corresponding address of a light beam before starting the high speed moving of a pick up is known, the address of a disk 11 to which the light beam corresponds after rapid feeding can be obtained by calculating from the number of jumped tracks. When detecting desired address by FF or REV action, the number of tracks to be jumped by the light beam can be obtained from address before starting searching action and address for which retrieval is desired. Consequently, accurate searching action can be performed by a simple constitution.

Abstract: PURPOSE:To convert a leading-in speed at the time of an automatic focus control lead-in to a high speed in an optical disk device, by changing stepwise a moving speed of a focal position by a relative position of a recording film and a luminous flux. CONSTITUTION:When an automatic focus start is instructed from a control logical circuit 17, a leading-in control circuit 16 keeps a focus at a distance from the surface of an optical disk for a prescribed time, and thereafter, makes the focus approach the disk 1 at an automatic focus leading-in possible speed being the first speed. When the focus approaches the disk, an output signal 20 is obtained in a photodetector 9, but when the focus approaches a recording film 2 to a prescribed distance, a comparator 14 detects a level by an output signal V1 corresponding to this distance, and outputs a detecting signal 21. By this signal 21, the approach speed of the focus is switched to the second speed by the circuit 16, and also it is made to approach the surface of the film 2. When the cross reaches the crossing to the surface of the film 2, a comparing circuit 15 detects it, and outputs a crossing signal 24. When this signal 24 is inputted to the circuit 17, a start signal 25 of an automatic focus control is outputted.

Title: Curable wear-resistant composition
Inventor: KATSUNO NOBUHIRO
IPC: C09D5/00
Filed: 1985-09-04
Abstract: PURPOSE:To obtain a curable compsn. which gives a coating agent having high wear resistance, by incorporating leaf-from ceramic pieces in a binder for coating agent. CONSTITUTION:A curable compsn. comprises a wear-resistant coating agent obtd. by incorporating leaf-form ceramics pieces in a binder for said agent. Said binder may be an org. binder. However, when heat resistance is required, an inorg. binder is preferred. Since said coating agent contains the binder contg. leaf-form ceramics pieces, it can be applied with a trowel or a spatula as in conventional coating agent, and the ceramic pieces are applied one upon another nearly in parallel on the surface of a material to be coated. Thus, the space between the ceramics pieces is so small that there is left no part where no ceramic piece is interposed between the surface of the coated layer and the surface of the material to be coated. As the org. binder, epoxy resins are preferred from the viewpoints of wear resistance, workability, toughness, flexibility and cost. As the inorg. binder, silicate binders are preferred from the viewpoints of heat resistance, adhesion and workability.
