Title: Manufacture of aluminum parts
Inventor: YAMAMOTO YOSHIFUMI
IPC: C22F1/00
Filed: 1987-10-15
Abstract: PURPOSE:To easily remove a burr part without causing cracks, etc., on a burr- removed part by alkali-cleaning an Al-formed body forged into a prescribed shape and blackening the surface before cutting and removing the residual burr part by laser beams. CONSTITUTION:Al die stock is forged into a prescribed shape to form a forge- formed body 2 in the external circumferential part wherein burr parts 3 are expanded. Then, this forge-formed body 2 is dipped for about 5-10min. in aq. soln. 5 of sodium hydroxide having a liquid temperature of about 20 deg.C and a concentration of about 54g/l in a liquid vessel 4 to blacken the surface. Laser beams L are projected from a head for laser beam machining along the boundary between this blackened forge-formed body 2 and the burr part 3 to fuse and remove the burr part. Moreover, the forge-formed body 2 free from the burr part 3 is subjected to picking. Thereby, the burr part 3 can be quickly and surely removed without causing cracks, etc., at the places where the burrs have been removed.

Title: Control device for automatic start clutch
Inventor: HIRANO SADAYUKI
IPC: F16D48/02
Filed: 1989-10-05
Abstract: PURPOSE:To protect a take-off clutch from temperature rise due to high load for many hours by reducing a target engine speed, when a stall condition or a nearly stall condition is continued over a prescribed hours at high throttle opening. CONSTITUTION:At take-off, a target engine speed is instituted by a deciding means 103 corresponding to a throttle opening theta, PI computation 106 is performed with deviation from the actual engine speed Ne, a feed forward quantity from a deciding means 101 is adjusted, PID computation 109 is performed with deviation from clutch pressure Pc, and a take-off clutch is duty controlled. Further, the target line pressure is instituted by a setting means 111. When a stall condition (clutch loss   engine output) is continued at high throttle opening, the target engine speed decided by the target engine speed deciding means 103 is reduced to reduce clutch loss of the take-off clutch. Thus, the take-off clutch can be protected from damage at temperature rise due to high load for hours.

Title: Optical recording medium
Inventor: IKOMA KEIKO
IPC: G11B7/24012
Filed: 1986-11-04
Abstract: PURPOSE:To permit recording and reproduction with high sensitivity by laminating fine polymer particle as a recording layer. CONSTITUTION:This optical recording medium is formed by providing the recording layer 9 consisting of the fine polymer particle via a reflection layer 8 on a substrate 7 and providing a protective layer 11 as the outermost layer via an adhesive layer 10 on the recording layer 9. Since the recording layer 9 is formed by laminating the fine polymer particle in the above-mentioned manner, the fine polymer particle of a part 12 projected with laser light for writing is melted and softened by the projection of the heat-mode laser light although the surface is rugged. The rugged surface is then smoothed, by which pits are formed and information is written. While the part not projected with the writing light is low in reflectivity, the part 12 projected with the writing laser light where the pits are formed is smoothed and, therefore, the reflectivity is high. Reading is executed from the difference in the reflectivity of both parts by projecting a reading out ray 13 thereto. The pits are thereby formed with the high sensitivity.

IPC: G06F3/06
Filed: 1991-10-09
Abstract: PURPOSE:To obtain a method for improving fault resistance against the access fault of a drive in a large disk sub-system connecting multiple drives. CONSTITUTION:When statistical information on the occurrence of an access error which can be corrected on a present-use drive (track) is collected and it is judged that there is the omen of the fault of the present-use drive (track) based on said information, a disk controller 100 copies data from the present-use drive (track) to a standby drive (track) and switches the present-use drive (track) to the standby drive (track).
