Title: Lens cleaning device for optical disk device
Inventor: ASAKA KOICHI
IPC: G11B7/12
Filed: 1995-03-10
Abstract: PURPOSE: To blow off the dust of a lens with a simple structure by moving an objective lens to an air emitting position and emitting air to the lens in the contraction of an air damper. CONSTITUTION: An optical head 12 is moved by a traverse mechanism 10 in the state that an optical disk is discharged, and an objective lens 11 is positioned in the air emitting port 4d of a lens cleaning air damper 4. The position of the head 12 is then detected by an optical head position detecting part 8 to control the mechanism 10. When a vehicle travels, the irregularities of a road surface and the vibrations of an engine are applied to an external housing 2 and are absorbed by dampers 3, 4. Whenever the damper 4 absorbs the vibrations, it repeats contraction and expansion, and air is blown toward the lens 11 at the time of contraction. Therefore, dust on the lens 11 is blown off, so that the lens 11 may be cleaned.

Title: Manufacture of composite girder material
Inventor: YAMAMOTO SHIRO
IPC: B29C70/06
Filed: 1987-03-09
Abstract: PURPOSE:To make it effective in manufacturing girder materials having various cross sections, exellent in productivity and profitable in cost by a method wherein a resin-impregnated fiber is wound round a mandrel and, after being semi- hardened, removed from the mandrel, deformed in an intended shape and finally the resin is hardened under the state that said intended shape is maintained. CONSTITUTION:Resin and fiber are selected and the winding angle is selected to be 5-30 deg. or 60-88 deg.. A resin-impregnated fiber is wound round a mandrel, to which Teflon coating is applied. When the predetermined winding is finished, the fiber is semi-hardened as wound up. When the predetermined viscosity or 10<3>-10<7> P is attained by the resin of the fiber, the fiber is removed from the mandrel. Firstly, the central parts of the fiber are joined by pressure to each other and, after that, the remaining loop-shaped parts are also joined by pressure for hardening. For industrial production, an intermediate stock 1, which is produced by FW (filament winding) method is joined by pressure with pressure-joining rollers 5 and bonded with pressure-joining heaters 6. If necessary, the fiber is finally hardened in a curing oven under the state that the shape of the fiber is kept with an auxiliary shape retaining tool.

Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the use efficiency of a polishing member so as to remarkably reduce the polishing cost by shifting the relative positions of a fixing jig board and a polishing member. SOLUTION: A polishing board 25 is revolved by designated amount of eccentricity by a revolving motor 17, and rotated by a rotation motor 11. Each rod- like member W has an end face pressed to a polishing member through a fixing jig board 27. Thus, the polishing locus of the center position of plural rod-like members W in the polishing work is formed annularly on a part of the polishing member on the polishing board 25. Subsequently, the position of the fixing jig board 27 to the polishing board 25 is changed little by little to perform polishing, thereby forming plural polishing loci. Thus, the substantially whole surface of the polishing member is used on the average.

Title: Portable radio communication set
Inventor: SUGANO HIROYUKI
IPC: H04W88/02
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To suppress the useless power consumption by cutting the supply of power to a liquid crystal display means in order to discontinue the display of information when a portable radio communication unit is stored in a bag, etc., and the display of information is not required to the display means. SOLUTION: When the call data are received, a reception notification means 7 is operated to notify the owner of a portable radio communication unit of reception of the call data. At the same time, the brightness is detected by an optical sensor 4 in an environment where the portable communication unit is used. Then the voltage is outputted based on the detected brightness. A comparison means 6a compares the output voltage value with the threshold value, i.e., the reference of brightness of the unit working environment that is stored in a memory 11. In a dark state where the brightness is lower than a prescribed level (i.e., when the portable communication unit is stored in a bag, etc.) and not used, a power control means 6b cuts the power to be supplied to a liquid crystal display means 8 from a power supply 5. Thus the useless power consumption can be suppressed.
