Title: Torque sensor input circuit of motor-driven power steering
Inventor: ASHIZAKI YUKIHIRO
IPC: B62D5/04
Filed: 1989-02-14
Abstract: PURPOSE:To make compensation of a system by furnishing an OP amp. buffer at the output part of a torque sensor, lowering the output impedance, raising the anti-noise property, and by providing a reed lug filter of non-inversion type at the input part of a controller. CONSTITUTION:At the interface between a controller 17 and a torque sensor 12 in motor-driven power steering, a torque signal given by a torque signal generator part 1 is first converted into voltage source with low output impedance by an OP amp. buffer 2. Then the torque signal is fed to a reed lug filter 3 of non-inversion type with high input impedance through a harness, and then it is converted into digital signal by an A/D converter 4 to be fed to a microcomputer 5. This lowers the output impedance of torque sensor 1 and enhances the anti-noise property, and further the torque sensor circuit is simplified to accomplish constructing it in a small size and at low cost.

Title: Recursive reflective adhesive sheet
Inventor: TAKADA HIROTAKA
IPC: G02B5/13
Filed: 1989-02-14
Abstract: PURPOSE:To allow easy remote reading of optical information by providing an optical layer having a recursive reflective property on a transparent base film and sticking this layer to a reflector, thereby forming the recursive reflector. CONSTITUTION:This sheet has the transparent base film 13T, the many small recursive reflectors 11 layered and formed on one surface side of the base film and a transparent adhesive agent layer 12a laminated and disposed on the small recursive reflector side thereof and is stuck to a reflecting surface 1w to form the recursive reflector. Namely, the recurrent reflective adhesive sheet 10 is stuck by the outer adhesive agent layer 12a to a base material 1. If the base film 13T is irradiated with the reading light beam of a bar code reader from the other surface 13s side in this state, the projecting light beam arrives through the glass beads 11 at the surface 1w of the base material 1 by adequately selecting the refractive indices of the glass beads 11 and the transparent adhesive agent layers 12a, 12b. The light beam reflected by this surface 1w again passes the glass beads 11 and is nearly paralleled with the projecting light beam. The remote reading of the optical information is facilitated in this way.

Title: Recording and reproducing device
Inventor: FUJIMORI SHINYA
IPC: G11B5/53
Filed: 1994-03-04
Abstract: PURPOSE:To surely regulate reproducing times of provided information once by recording this recording medium with a different signal from a signal of this information simultaneously with reproduction of the information signal. CONSTITUTION:When a head 4 starts to scan, for instance, a track 11 from a position of H3 and the head 4 reaches a position H3'', a head 1 starts to scan a track 10 from a position of H2. At this time, the track 10 has been scanned by a head 5 to complete reproduction of its signal before scanning of the head 4 on the track 11. At the time of scanning the track 10 by the head 1, when such a magnetic field as to erase the signal of the track 10 is generated, the signal recorded on the track 10 is erased. Alternatively, at the time of scanning track 10 by the head 1, when a signal different from the signal of the track 10 is recorded while superposed on the track 10, the signal of the track 10 is turned into the different signal from the signal before being scanned by the head 1. This is repeated on the following tracks.

Title: Magnetic head
Inventor: ISOZAKI MAKOTO
IPC: G11B17/32
Filed: 1978-03-27
Abstract: PURPOSE: To reduce the sliding abrasion of recording media and perform good recording and reproducing by making the radius of curvature of slider contact face to values of a specified range and gently and continuously changing the radius of curvature toward the circumferential edge part.  
     CONSTITUTION: The radius of curvature R 1  of the contact of face of a slider 4 in the sliding direction of a medium 1 is 3 to 20m and the radius R 1  continuously changes so as to become a smooth curve toward the circumferetial edge part chamfered at a radius of curvature R 3 . The contact face rectangular to the sliding direction is 0.3 to 5m in radius of curvature R 2  and is formed with a similar smooth and continuous curved face. When this slider 4 makes pressure contact to the medium 1, the contact pressure is dispersed by the curved face of the circumferential edge part of the radius of curvature R 3  and even if a change in the posture of the slider 4 occurs, shaping away of the medium surface does not occur and the sliding abrasion decreases. In addition, even if the posture of the slider 4 changes owing to the spherical face formed by the specified radii of curvature R 2 , R 3  of the contact face, no clearances are produced between the recording-reproducing core and the medium, thus good recording and reproducing are accomplished.

Title: Information recording medium
Inventor: KOTAKA KAZUHIRO
IPC: G11B7/24097
Filed: 1987-02-20
Abstract: PURPOSE:To prevent generation of double refraction and to permit exact recording and reproduction by using substrates formed in such a manner that the residual tensile stresses as much as to offset the compressive stress of bonding are previously made to exist in the regions near the coupling part. CONSTITUTION:The substrates have undercut parts 4, 5 near the regions where the substrates contact a magnetic material. The tensile stresses PT generated when the substrates are stripped from metallic molds remain in said parts. Although the undercut parts 4, 5 may exist on either one or both of the front or rear faces of the substrates, said parts are provided to a continuous annular shape in order to obtain the uniform stresses. The compressive stresses Pc generated by tightening of screws and the tensile stresses PT remaining in the substrates offset each other to form a stressfree state. The degree and range of the residual tensile stresses can be set at desired values by adequately selecting the formation and position of the undercuts, the molding conditions of the substrates, etc., and are, therefore, adequately determined according to the tightening strength of the screws. The generation of the double refraction in the region near the coupling part of the substrates is thereby prevented.
