Title: Magnetiic recording medium
Inventor: EBINE YOSHIHITO
IPC: G11B5/74
Filed: 1992-05-27
Abstract: A magnetic recording medium comprises a nonmagnetic substrate (1), and a magnetic layer consisting of a first ferromagnetic metal thin film (2) of an orthorhombic, columnar structure formed on the nonmagnetic substrate (1), and a second ferromagnetic metal thin film (3) of an orthorhombic, columnar structure. The direction of growth of the orthorhombic, columnar structure of the first ferromagnetic metal thin film (2) and that of the second ferromagnetic metal thin film (3) are opposite to each other. The thickness of the first ferromagnetic metal thin film, the thickness of the second ferromagnetic metal thin film, the coercive force and remanent magnetic flux density of the magnetic layer, the longitudinal stiffness and surface roughness of the back surface of the magnetic recording medium are determined selectively so that the magnetic recording medium is able to function satisfactorily regardless of the direction of movement of the magnetic head relative to the magnetic recording medium in reproducing recoded data by a recording/reproducing apparatus of a nontracking data reproducing system and a nonloading tape drive system.

Abstract: An optical frequency division multiplexing transmission system for sending a large volume of information by a single optical fiber is disclosed. Each of an optical frequency division multiplexing transmitter equipment and an optical frequency division multiplexing receiver equipment has an optical filter (4, 8) having a periodic optical transmission characteristic therein. Each optical filter is stabilized with an absolutely-stabilized standard optical frequency. Each optical signal frequency is stabilized to a periodic transmission characteristic of the optical filter arranged in the optical frequency division multiplexing transmitter equipment, and each local frequency to a periodic transmission characteristic of the optical filter arranged in the optical frequency division multiplexing receiver equipment. Even in the case where no optical signal is applied to the optical frequency division multiplexing receiver equipment due to such causes as a fault of the transmission optical source or the breakage of an optical fiber, the local optical source frequency continues to be controlled in stable fashion.

Abstract: A low impedance ovevoltage protection circuit includes a first MOSFET having a drain connected to an input signal and a source connected to a drain of a second MOSFET, the source of the second MOSFET being coupled to the output. The gates of the first and second MOSFETs are connected to voltage supplies which float relative to the input signal values so as to maintain the gates of the respective MOSFETs biased to a conducting state. The maximum and minimum values to which the floating voltage supplies will float are defined by clamping diodes and clamp voltage sources. When the input signal value exceeds a desired positive maximum value, the first MOSFET is no longer biased to an on state whereby the MOSFET turns off, shunting the input signal through a high impedance for limiting input current and removing the input signal from the output. Negative going peak values are removed in a like manner by the second MOSFET. Bipolar transistors are coupled to each MOSFET to allow quick turn off in the event of rapid rise time transient input values.

Title: Disk drive unit
Inventor: TAJIMA FUMIO
IPC: H02K1/14
Filed: 1992-03-11
Abstract: A motor has a stator (4) and a rotor (3), the stator (4) having cores (9A) and drive coils (1) which generate magnetic fields for rotating the rotor (3). The stator (4) also has a yoke (9B,9C) surrounding the rotor (3) and the rotor (3) is positioned such that it is closer to one part (9B) of the outer periphery of the yoke than another part (9B) of the yoke. Such a motor is particularly suitable for use in a disk drive unit as a spindle motor (2) for rotating the disk (1). Then an actuator (12) for moving a head (11) may be located adjacent the part (9B) of the outer periphery of the yoke (9b,9C) which is closest to the rotor. This permits the head (11) to approach closely the axis of rotation of the disk (1) without the spindle motor (2) interfering with the movement of the head (11). The continuous yoke (9B,9C) prevents magnetic flux leakage from the spindle motor interfering with the actuator (12). The actuator (12) may itself have a yoke (9D) integral with the yoke (9B,9C) of the spindle motor (2), and/or other components in common.

Abstract: The present invention features an improve technique for slowing and stopping a vehicle having an electric service motor (12), a mechanical parking brake (35), and a deadman's switch (10) for engaging the mechanical brake. The method of the invention improves the efficiency of the braking procedure. The braking method initially determines if the deadman's switch is engaged. If it is, then the electric service motor is plugged at a predetermined minimum plug rate until the vehicle slows to a specified velocity. When the specified velocity is reached, the plugging operation is terminated. The mechanical brake is then engaged to slow the vehicle to a halt. When the vehicle comes to a halt, the parking brake remains engaged. The invention also improves safety by increasing the controlled rate of plugging to a maximum value in the event that the deadman's switch is off. Actual braking performance by plugging is compared with that of accepted rates of deceleration or plugging effort shown by armature current to verify operation of the service braking system. In the event of inadequate service braking, such braking is terminated and the mechanical brake is applied.
