Title: Optical information recording and reproducing device
Inventor: NAKAHARA TAKASHI
IPC: G11B19/00
Filed: 1988-07-06
Abstract: PURPOSE:To prevent unnecessary oscillation at the time of reciprocated movement by causing the driving means of a mobile stand to be a linear motor and using the center yoke of the linear motor as the guiding means of the mobile stand. CONSTITUTION:The linear motor is constituted together with a magnetic circuit to be composed of a center yoke 1, an upper yoke 4, a lower yoke 5 and permanent magnets 6 and 7 and driving forces F and F' are generated in the longitudinal direction of the center yoke 1. Further, since the power points of the driving forces F and F' are constituted so as to be almost positioned in a guiding plane which includes V pulleys 9a-9d, the center of gravity G is almost included in the guiding plane as well. Thus, since the power points of the driving forces F and F' and the center of gravity G of a moving part are almost coincident in the guiding plane, the moment of force to generate pinching in a vertical direction or yawing in a horizontal direction is not generated. Thus, the pinching in the vertical direction or the yawing in the horizontal direction to be generated at the time of the reciprocated invertion can be prevented.

Filed: 1989-06-28
Abstract: PURPOSE:To dispense with a redundant system for the data area of an optical disk and to improve the working efficiency of the data area by providing a defective position information register and an alternate data storage part in an optical disk device. CONSTITUTION:Before a host device processes read/write data, defective part position information and alternate part position information are read out of defective part and alternate part position information recording parts provided on the optical disk 22 via read and write heads 20 and 21, and are stored in a defective position information recording register 8. A position signal register 4 generates a selection position signal 5 based on a read/write head selection signal 1, a track position instruction signal 3, and a sector position instruction signal 28 from the host device. A position signal comparison part 7 compares and collates the signal 5 with all the defective part position information stored in the register 8, and selects the alternate data storage part 16 with a data signal selection part 13. Therefore, it is possible to dispense with the redundant system for the data area of the optical disk, and to improve the working efficiency of the data area.

Title: Detection of variations in flux filling rate
Inventor: SAKAI YOSHIYA
IPC: G01N27/72
Filed: 1984-08-13
Abstract: PURPOSE:To achieve a stable and highly accurate detection of variations in the flux filling rate along the length of a flux-filled wire in a non-destructive manner, by measuring the thickness of skin metal. CONSTITUTION:Two resonance circuits containing a coil and a capacitor are arranged in series along the direction of running a flux-filled wire and a wire 3 is passed through coils 1 and 2. If so, impedances Z1 and Z2 are generated in the coils 1 and 2 corresponding to the parts A and B of a skin metal due to electromagnetic induction. The level of the impedances Z1 and Z2 is determined by the thickness of the skin metal. The non-equilibrium state of the impedances Z1 and Z2 can serve for judgement as data indicating variations in the flux filling rate at the parts A and B of the skin metal. Thus, variations in the flux ratio can be detected continuously in a non-contact state from outside the wire 3.
