Title: Magnetic head
Inventor: SAKAI KUNIHIDE
IPC: G11B5/133
Filed: 1988-09-26
Abstract: PURPOSE:To prevent the generation of cracking and chipping at the point of the nonmagnetic spacing of cores by implanting nonmagnetization ions to the tape traveling surface of a core body, thereby forming the nonmagnetic spacing. CONSTITUTION:N ions are implanted between a hole 4 for winding of the core body 2 and the tape traveling surface A to form the nonmagnetic spacing 8. The core 2 consists of a ferromagnetic oxide of an approximately rectangular parallelepiped shaped, for example, MnZn ferrite single crystal. The hole 4 for winding is formed transversely through the core body 2 in parallel with the tape traveling surface A to approximately the center of the width W of the core body 2 and of the distance l0 downward from the tape traveling surface A. Since a spacing, more particularly a mechanical spacing is not formed to the rear part side of the core block in this way, the strength of the core block is improved and the generation of the cracking and chipping is prevented. Since the spacing is not formed both physically and mechanically to the rear part side of the core block, the magnetic resistance of the core block lowers and the recording and reproducing characteristics of the magnetic head are improved.

Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To simplify the circuit structure to reduce the manufacturing cost, and enhance the assembling property by generating a control signal pressure within a shuttle block and outputting it to operating equipment. SOLUTION: Shuttle valves 61-75 are built in a shuttle block 50, and the low pressure system of the shuttle valves is perfectly separated from the high pressure system of flow control valves 5-13 in order to generate and output a control signal pressure within the shuttle block 50.

Abstract: PURPOSE:To handle information for each sector by providing the header information in the form of a convex/concave pit and using independently the detection means for header and data areas respectively. CONSTITUTION:The header information is provided in the form of a pit 3 to a guide groove 2.

Title: Power supply device
Inventor: YOKOZEKI ICHIRO
IPC: H05B41/282
Filed: 1991-09-21
Abstract: PURPOSE:To provide a power supply device which can reduce distortion of a current waveform even if a load fluctuates. CONSTITUTION:A chopper means 2 varies a voltage by chopping. An error amplifier 3 compares a voltage at a connection point of a resistor R1 and a resistor R2 with a reference voltage at a reference voltage source E1 and then outputs an error signal corresponding to a voltage difference. A PWM controller 4 varies an ON-duty of a switching element Q1 according to the error signal. A ripple component superposition circuit 5 takes out only a ripple component which is virtually two times larger than a commercial AC power supply E from a pulsating current output of an all-wave rectifier 1. The ripple component is superposed on the error signal in a same phase as that of the pulsating current voltage. A ripple component control circuit 6 detects a load current which flows to a resistor R5 and then increases resistance of a variable resistor R4 when the load current is increased. On the other hand, when the load current is reduced, the resistance of the variable resistor R4 is reduced, thus enabling distortion to be reduced.
