Title: Optical pickup device
Inventor: YOSHIHARA TORU
IPC: G11B7/135
Filed: 1985-09-10
Abstract: PURPOSE:To prevent the input of undesired stray beams by providing an aperture which limits the beam diameter of the laser light serving as the scattered beams and supplying only the desired light to a collimator lens. CONSTITUTION:The laser light delivered from a laser diode 6 serves as the scattered beams and therefore are made incident on diffraction grating 5 with spread as shown by the dotted lines. Then the laser light is separated into + or -n-degree light by the grating 5. The beam diameter of the light passed through the grating 5 is limited by an aperture 4 and made incident on a collimator lens 2 through a half prism 3. In this case, the laser light is made incident on the lens 2 to be turned in parallel beams as shown by the slid lines without hitting the inner wall of a holder 8. These parallel beams are condensed on a disk 9 by an objective lens 1. The reflected light given from the disk 9 traces an optical path reverse to that of the incident light and is reflected by the prism 3. This reflected light is made incident on a photodetector 7 and turned into electric signals. Thus the stray beams can be deleted and the spot quality is improved. This ensures the accurate measurement of the radiation power.

Title: Wiper device
Inventor: HONDA YUKIO
IPC: H02P1/22
Filed: 1982-11-16
Abstract: PURPOSE:To decrease the impact noise occurring at reversed time and improve the durability by equipping the switch circuit reducing the wiping speed of a wiper blade, while detecting the position of the wiper immediately before reversing. CONSTITUTION:When a wiper blade reaches the position immediately before reversing while passing the intermediate position of wiping, the sliding contact of the movable part 51 of a cam 5 with contactor 53, 54 is released. Then bias current flows through the base circuit of a transistor 7 which flows the current therethrough. By this flowing therethrough of the transistor 7, a diode 9 also flows the current therethrough, and the current for very low speed between the brush 15 and the brush 18 of a motor M flows, thereby shifting the motor M to very low revolution speed. Next, the wiper blade passes the reversing position, and the movable part 52 of the cam 5 is successively caused to be in contact with the contactors 53, 54 again, and simultaneously the transistor 7 becomes OFF, whereby the wiping operation of an original speed is restored.
