Title: Disk device
Inventor: YAMAGUCHI AKIHIRO
IPC: G11B21/12
Filed: 1986-09-24
Abstract: PURPOSE:To prevent damage to a head and a disk and to reduce the access time by energizing a reaction force in following to the relative movement of a forced contact/disconnect means of the head and the disk so as to decelerate the moving speed exponentially in response to the moving distance. CONSTITUTION:An energizing member 4 is engaged between a reflector unit 3 and a carriage body 1. Since the carriage 1 is driven counter clockwise, the unit 3 and the carriage 1 are moved in the parting direction, one engaging end 42 of the member 4 is tensed, and the reaction force is energized which is composed of compressing force by a piston 45 and a viscous oil 43 caused by the elastic force of a compression spring 49 and of sliding face resistance between the piston 45 and a cylinder 41. The compressing force is acted as a negative acceleration and when a motor 12 drives the carriage 1 at a constant torque, the drive speed of the carriage 1 is decelerated exponentially. Thus, the damage of the head and the disk 10 is prevented and the access time is reduced.

Filed: 1993-08-16
Abstract: PURPOSE:To secure safety and reliability of a tire and turning travelling at the time when air pressure is lowered by controlling an engine so that an output characteristic against an operating amount of an accelerator pedal becomes a specified basic characteristic and at the time when tire air pressure is lowered, it becomes a correction characteristic on the output restraining side. CONSTITUTION:A tire air pressure judging device, in accordance with each of output signals from each of front, rear, left and right wheel speed sensors 51-54 in an automobile and an initializing switch 55 on an instrument panel and others, drives and controls a warning lamp 56 of the inner panel and others by a control unit 50. That is, at the time of detecting lowering of tire air pressure, warning is output. In this case, an operating amount of an accelerator pedal 17 is detected by an acceleration sensor 19. Additionally by an engine control device 20, an engine 5 is controlled so that an output characteristic against the operating amount of the accelerator pedal 17 becomes a specified basic characteristic. In the meantime, at the time when the tire air pressure is lowered, the engine 5 is controlled so that it becomes a correction characteristic on the output restraining side rather than the basic characteristic.

IPC: H04N5/376
Filed: 1990-08-24
Abstract: PURPOSE:To extract a picture signal of an image sensor from which a reference picture signal is outputted later timewise than a picture signal by using a clamp circuit so as to clamp the picture signal being an output signal of the image sensor whose DC component is eliminated to a reference voltage based on a clamp pulse. CONSTITUTION:A DC component of a signal S1 from an image sensor 3 is eliminated by an AC coupling circuit 11. On the other hand, a clamp pulse set for a prescribed period synchronously with reset of a picture signal l1 is outputted from a clamp pulse generating circuit 12. Then the picture signal l1 is clamped to a reference voltage outputted from a reference voltage generating circuit 14 by operating a clamp circuit 15 based on the clamp pulse and a reference O1 of the picture signal l1 is outputted as a picture signal level relatively. Thus, a signal S2 representing a level of the picture signal is extracted from the output signal S1 of the image sensor 3.

Filed: 1989-08-31
Abstract: PURPOSE:To improve frequency characteristics by adding the signal at the transmission end of a delay line to the signal at the reception end, amplifying the result with a specific factor, and finding the difference between the signal appearing at an intermediate tap of the delay line and the output signal of a summing amplifier and outputting a cosine equalized signal.

The summing amplifier 23 adds those two signals and amplifies the sum with the specific factor (K/2) to obtain (K/2)X(f(t+tau)+f(t-tau)). A differential amplifier 24 subtracts the output of the summing amplifier from f(t) to obtain the cosine equalized signal f(t)-(K /2)X(f(t+tau)+f(t-tau)), which is outputted from an output terminal. Therefore, the cosine equalizer with excellent frequency characteristics is easily formed.

Filed: 1990-08-29
Abstract: PURPOSE:To reduce the wear of a magnetic disk by providing a mechanism to make the yawing angle of a magnetic head slider large at the time of contact start/stop (CSS). CONSTITUTION:When the rotation of the magnetic disk 1 reaches a rated number of revolution, an actuator 7 moves, and the yaw angle 5 attached to an inner periphery side slider 4 is made small so as to fix the motion of the actuator 7 in a lateral direction at the time of the operation of a magnetic disk device, and after that, it acts as the actuator of a usual rotary type. At the time of the operation of the magnetic disk device, a slider moves in a range from the inner periphery side slider 4 at the time of the operation of the magnetic disk device to an outer periphery side slider 6 at the time of the operation of the magnetic disk device. Accordingly, at the time of the CSS, the slider yawing angle is large, and the floating characteristic of the magnetic head slider is never impaired. Thus, the wear of the magnetic disk can be reduced.
