Title: Formation of holographic stereogram
Inventor: TANIGUCHI YUKIO
IPC: G03H1/26
Filed: 1986-11-06
Abstract: PURPOSE:To obtain a reproduced image having invariably uniform brightness even when a view point is shifted in position by varying an exposure time for each division area and uniforming the quantity of exposure of each division area. CONSTITUTION:The formation of a holographic stereogram consists of a 1st stage wherein plural negative films having projection images of a three-dimensional object 1 in plural directions are formed and a 2nd stage wherein the photosensitive surface of a hologram photosensitive plate 6 is divided into plural division areas and hologram diffraction images are formed by exposure in the division areas corresponding to the projection directions of the 1st stage by utilizing the interference between light from the negative films and reference light as to the plural negative films. When the hologram diffraction images are formed by exposure in the 2nd stage, the respective division areas are made different in exposure time to uniform the quantities of exposure of the respective division areas. The relation of exposure quantity=light intensityXexposure time is utilized to uniform the exposure quantity distribution of the respective division area by adjusting the exposure time even when the light intensity distribution is irregular. Consequently, a reproduced image having invariably uniform brightness even when viewed from any view point is obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a washer and a fulcrum assembly structure incorporating the washer, which can hold a torque of a screw through engagement with threads so as to prevent the screw itself from being loosened. SOLUTION: In a washer 30, a plurality of engaging pieces which are projected inward of a through-hole having a diameter which is slightly larger than the outer diameter of threads of a screw, are formed in the interior of the through-hole at equal intervals, the degree of projection of the front end parts of these engaging pieces being set to be in a range between the outer diameter of the threads 42, and the root diameter thereof. Further, either one of surfaces at the peripheral edge of the through-hole is formed therein with a plurality of penetration guides 32 which are upright to this surface and which are laid along the through-hole, and the penetration guides 32 are formed with protrusions 33 whose size is slightly increased outward.  When the members are coupled with each other by means of the screw, axial force is held through the screw for a long time, and accordingly, the screw is not loosened even though the members are rotated, relative to each other, so as to obtain a stable slide resistance. Further, a washer can be precisely set in a guide hole. Thus, the washer can be easily attached and removed without the washer coming off.

Title: Optical disk device
Inventor: FUKUDA MISAO
IPC: G11B7/09
Filed: 1988-10-21
Abstract: PURPOSE:To highly accurately detect the position of a half mirror without increasing the area of a position detector by using a photoreceptor element as the position detector for a half mirror which leads an optical beam in the direction perpendicular to an optical disk. CONSTITUTION:A parallel optical beam (a) irradiates an optical disk medium 1 after its direction is changed by a half mirror 2. When the beam (a) is made incident on the mirror 2, part of the beam (a) passes through the mirror 2 and expanded by means of a concave lens 3. A photodiode 4 is provided on the extended line of the expanded optical beam (b). Since the radius of the optical beam (b) passed through the lens 3 expands at a fixed angle, a 1:1 relation exists between the light quantity (c) detectable by the diode 4 and the position R of the mirror 2. Accordingly, when the relation between the position R of the mirror 2 and light quantity (c) of the diode 4 is checked, the position R can be found by detecting the light quantity (c). Therefore, highly accurate position detection can be performed without increasing the area of the position detector.
