Title: Optical disk apparatus
Inventor: SANO HIDEO
IPC: G11B19/02
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To search for blank sectors, written sectors at high speed by recording written blank data to an area not used. SOLUTION: Written blank sector(WBS) information are written in a RAM 4 by a sector address information editing mechanism part(SAC) 5. A CPU 3 lets the SAC 5 edit addresses of sectors and write the result to the RAM 4 when the data are to be written in a userband and lets a WBS-writing mechanism part 7 write the addresses to unused areas from the RAM 4 when an optical disc is discharged. When the optical disk is inserted, the CPU 3 outputs a read instruction to a WBS-reading mechanism part 6 to let it write data to the RAM 4. When a using sector is searched from a host device 1, the data in the RAM 4 are transferred via a SCSI controller 2. Search for unused sectors is carried out by editing addresses of unused sectors in the RAM 4 and transferring the result via the SCSI controller.

Filed: 1985-09-02
Abstract: PURPOSE:To improve the response characteristic of a tracking servo by detecting the direction of eccentricity of a disc from an RF signal and a track ing error signal outputted from the disc and using the detection signal to drive a hammer thereby eliminating almost the eccentricity error of the disc. CONSTITUTION:The relative moving direction ID between the optical pickup and the optical disc is detected from the tracking signal TE and the reproduced RF signal. A pulse signal Pm is outputted from an eccentricity maximum detec tion section 27 at the maximum eccentricity and when the range of eccentricity is a stroke or over, an H level signal Pw is outputted. When these outputs go to H level, the hammer section 25 is driven via a drive circuit 24 and a hammer 25A of the hammer section 20 knocks an optical disc 20 to reduce the eccentricity.

Title: Casing for air bag device of vehicle and its cover member
Inventor: TANABE TAKATOSHI
IPC: B60R21/217
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent growing of cracks on both side parts of a projection of an inwall part of an engagement hole part by engaging a click extending out of a cylindrical wall of a casing member with the upper side of a head end part of the projection projected to the inside of the engagement hole part from an opening end side inwall part of a cylindrical fit-in wall of the engagement hole part by extending it to the inside of the engagement hole part to be formed on the cylindrical wall. SOLUTION: As a casing member H1 is fixed on a proper point of a vehicle, a projection 23 of each engagement hole part 21 tends to displace in the working direction of force F against each click 11. Accordingly, each of the clicks 11 works to pressurize each of the projections 23 downward at its central part. However, as the projection 23 is integrally projected toward the inside of each of the engagement hole parts 21 from an intermediate portion of an inwall part of each of the engagement hole parts 21, even when each of the clicks 11 pressurizes each of the projections 23 downward, each of the projections 23 is only crashed toward the side of an opening end of a cylindrical fit-in wall 20 but each of the clicks 11 never makes directly contact with the inwall part of the engagement hole part 21 on its lower surface.

Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To reduce the damage of a substrate, to stably divide even a substrate of fine standards and to eliminate the insertion mistake of a substrate sheet while preventing the breakage thereof. SOLUTION: The leading end of a fed substrate sheet is inserted in the nip between a pair of rollers 14, 15 and allowed to protrude by 1mm by driving the lower roller 14. At this time, a break roller is rotated in synchronous relation to the lower roller 14 to be brought into contact with the protruding end of the substrate sheet to downwardly press the same by predetermined force. As a result of the action of the downward pressing force on the protruding end part of the substrate sheet 11 centering around the pressure holding part by the rollers 14, 15, a bar-shaped substrate 12 having predetermined width is broken from the substrate sheet 11 to be divided. By this constitution, the substrate sheet can be divided by proper force to obtain the bar-shaped substrate.
