Title: Optical card
Inventor: TOYODA KIYOSHI
IPC: G11B7/24012
Filed: 1988-02-22
Abstract: PURPOSE:To enable a desired image to be displayed as a positive image with a metallic luster on the back side of a recording layer and with a high quality feeling, by protecting the recording layer on a transparent base with a transparent film, and printing a negative image of a predetermined pattern on the surface of the transparent film. CONSTITUTION:A negative image N of a predetermined pattern is printed on the surface of a protective film 23, consisting of a transparent synthetic resin film, of an optical card 20. Namely, an ink 24 forms, for example, a gray ground (opaque layer) over substantially the entire surface of the protective film 23, leaving uninked parts 24c, 24f in the area of the pattern so that the protective film 23 is exposed in the pattern area surrounded by the gray ground. The negative image pattern N is protected by a hard coat 25 of, for example, a UV-curable resin. The protective film 23 is adhered to a recording layer 12 on a base 11 by a transparent adhesive layer 16. As a result, the surface of the recording layer 12b is partly seen through the transparent adhesive layer 16, protective layer 23 and hard coat 25, in the pattern surrounded by the gray ground of the printing ink 24, and shows a high reflectance. Therefore, the pattern is displayed as a positive image with a metallic luster.

Title: Heating roll for fixing device
Inventor: UEHARA YASUHIRO
IPC: G03G15/20
Filed: 1981-03-20
Abstract: PURPOSE:To provide a roll which withstands bending load thoroughly despite the average decrease in thickness, is decreased of heat capacity and is reduced of warm-up time by forming the heating roll core to the wall thickness thicker in the central part of the roll and thinner gradually toward the end part. CONSTITUTION:A metallic heating roll 1 is hollow, and its core part 2 of a cylindrical shape in outside circumferential surface and both end shaft parts 3 are coupled to one body in disc parts 4. The inside circumferential surface 5 of the core part 2 is formed to a tapered shape of the inside diameter increasing gradually toward the center of the core part 2 from the parts adjacent to the parts 4. Despite the slight increase in the wall thickness at the center of the roll core width and the increase in the bending ridigity of the heating roll, the wall thickness of the roll core is smaller toward both ends of the roll core and therefore the heat capacity of the heating roll can be made smaller than that for the prior art and the fixing device of a short warm-up time is obtained with no increase in the capacity of an electric power source.

Title: Shading coil type single phase induction motor
Inventor: KAWAMOTO TETSUO
IPC: H02K17/10
Filed: 1986-02-25
Abstract: PURPOSE:To obtain a good rotating magnetic field and to make a well-balanced winding possibly by positioning one face of a shading coil of quadrilateral cylinder with each face evenly thick and thin to the centre of nearly circumferential direction of a magnetic pole piece and by abutting the other three faces to both end faces and flank in the axial direction of the magnetic pole piece. CONSTITUTION:At equal intervals in the circumferential direction at least two (2) poles of pole pieces 4 and 4 of a stator 3 are projected from an annular ring-shaped yoke 5 towards the centre. The tip of the pole piece 4 fully spreads so as to face the outside circumference of a rotor (not shown in figure) provided in the centre position. On the other hand, a shading coil 8 for generating a rotating magnetic field is of quadrilateral cylinder with each face evenly thick and thin. A face of the quadrilateral is positioned in the centre of nearly circumferential direction of a pole piece 4, while the other three faces are so installed as to abut both end faces in the axial direction of the pole piece 4 and the flank of a base 4a. By this constitution, no resistance of the shading coil 8 varies widely and a good rotating magnetic field is obtained, while a bilaterally symmetric winding space can be assured with respect to the central line in the radial direction of the base 4a, so that a well balanced winding can be obtained.

Abstract: PURPOSE:To reduce unbalance vibrations during rotation by providing an oil feed section feeding lubricating oil to portions needing it and a fluid balancer receiving the lubricating oil from this oil feed section, storing it, and utilizing it to obtain the rotary balance. CONSTITUTION:When a crank shaft 5 is rotated, oil is fed to each sliding surface through an oil feed pipe 18, and the excessive oil drips to a sump section 16 through a gap between a lower bearing 10 and the crank shaft 5, and a predetermined quantity is gradually accumulated. At this time, the sump section 16 is being rotated together with the crank shaft 5, thereby the oil is depressed outward by a centrifugal force and is rotated along the inner surface of a side section 16d. If the rotary unbalance occurs, the oil quantity in the anti-eccentric mass direction against the eccentric mass A is increased as shown in the type figure, and it works as a fluid balancer, thus reducing unbalance vibrations. In the figure, O is the rotating main axis, G is the center of gravity, and S is the rotating center.

IPC: G11B7/125
Filed: 1989-02-21
Abstract: PURPOSE:To obtain a recording signal of high quality and remove restrictions on head main body materials by fixing a semiconductor laser to a prescribed plate, and attaching this plate to a head main body so that its angle can be adjusted. CONSTITUTION:A semiconductor laser 6 is fixed to an attaching plate 16, which is made of aluminium or the like and has the heat radiation effect, by an attaching screw 17, and this plate 6 is temporarily fixed to a head main body 15 with a coiled spring 20 between them by an adjusting screw 21. At this time, the front end of a projection 18 is inserted into an aperture 19 of the main body 15 to engage an outside peripheral surface 18A with a front end 19A of the aperture 19. For the purpose of correcting the deviation of the center of the intensity of parallel rays due to the variance of the angle of spread of the laser 6, the attaching angle of the plate 16 is changed by loosening or tightening the screw 21 in the proper position to match the center of the intensity of parallel rays, which passes a collimator lens 7, to its optical axis. Since the laser beam passes the center of an objective lens 5 by this constitution, a recording/reproducing signal of high quality is obtained on a disk 1. Restrictions on head main body materials are unnecessary.
