Title: Magnetic head
Inventor: HORIUCHI MASATO
IPC: G11B5/60
Filed: 1989-03-16
Abstract: PURPOSE:To substantially avert the superposition of external noises onto reading out waveforms by fixing a slider side face and a suspension by an electrically conductive adhesive. CONSTITUTION:The slider 1 is adhered to the jimbal part 3 of the suspension 2 by an electrically nonconductive adhesive 4, for example, an adhesive of an epoxy resin system. Further, a fillet is formed by the electrically conductive adhesive 5 to reinforce the adhesion. The slider 1 and the suspension 2 are, therefore, conducted therebetween by a resistance value of about max. 100OMEGA. The suspension 2 is usually fixed to an arm by screwing or caulking, etc., and the arm is conducted to the housing of a disk drive; therefore, the potential of the slider is eventually stabilized at the same potential as the potential of the housing of the magnetic disk drive. The superposition of the external noises on the reading out waveforms is substantially prevented in this way.

Abstract: PURPOSE: To perform the temperature compensation of the signal converter with a simple constitution by correcting one of the reference voltages to be applied to the leg mid-point of the semiconductor strain gauges forming a bridge with a resistance.  
     CONSTITUTION: A bridge circuit is formed by semiconductor strain gauges 1 thru 4. When the  reference voltages from a reference voltage circuit 13 are applied to the leg mid-points 38, 39 of  the gauges 1 and 2, 3 and 4, the potentials of the mid-points 38, 39 are made equal by the negative feedback current through an operation amplifier 30 and current source circuit 35 to which  the voltages of the mid-points 38, 39 are applied. This causes the amplitude output corresponding to the potential difference complying with the strains of the bridge output points 36, 37 being  driven at a constant current in the circuit 35 to be generated from the amplifier 30. In one of  these reference voltages applied to the mid-points 38, 39 is so adjusted by the variable resistor  44 provided to a zero point compensating circuit 42 that the potentials of the mid-points 38, 39  become equal at the time of a reference temperature according to the polarities of the gauges 1  and 2, 3 and 4, then the gauge rate temperature coefficient being approximately constant to  temperature is corrected and the temperature compensation of the strain quantity-electric signal  converter is well accomplished by the simple constitution using one set of resistance.

Abstract: PURPOSE: To measure the dynamic change of an oil film thickness, by causing a needle electrode to move vertically automatically in accordance with the vertical movement of the interface between oil and water to take out the change of the electric quantity of a capacity electrode.  
     CONSTITUTION: When a needle electrode 1 is brought into contact with the surface of water 18 in a minute depth, a corresponding electric resistance is generated between the electrode 1 and an underwater electrode 9. A rod mechanism 4 which moves the electrode 1 vertically and a driving servomotor 5 are operated as a loop while comparing this resistance value with the value of a reference resistance 8 so that the contact resistance value is always constant. Therefore, the rod part of the mechanism 4 follows the vertical displacement of the surface of water 18 while keeping always a constant depth for it. When a capacity electrode 2 is put in oil 19 floating on water, an electrostatic capacity corresponding to the thickness of oil 19 is generated in the electrode 2. The electrode 2 moves to follow the vertical displacement of the interface 20 between oil and water faithfully, and thus, the thickness of oil 19 is measured continuously with a high precision.
