    摘要： A flying head slider has gas bearing rails formed on a surface thereof disposed in opposed relation to a recording medium. The flying head slider flies at a microscopic distance above the recording medium by a pressure produced by a stream of gas resulted from the rotation of the recording medium. Each of the gas bearing rails comprises an inflow portion disposed at an inflow side of the gas stream so as to produce a pressure, an outflow portion disposed at an outflow side of the gas stream so as to produce a pressure, and a connective portion interconnecting the inflow portion and the outflow portion in a common plane. The connective portion serves to suppress an excessive compression of the gas, and achieves good damping characteristics.

    摘要： In a thin-film magnetic head having a magnetic core (upper magnetic layer), in the electromagnetic conversion section, which are composed of an upper first magnetic film, inorganic insulating film, and an upper second magnetic film, the upper first magnetic film is used as a second wiring for electrical continuity between the coil and input/output terminal. The upper first magnetic film is connected to the center of a coil which is of a single-layer structure. The first upper magnetic film is made of a same material as the coil and is formed simultaneously with the latter. In the region in which an input/output terminal backing is formed, the upper first magnetic film of a second wiring is removed. Thus, the electrical continuity is established between the input/output terminal and the center of the coil.Also, the utilization of the upper first magnetic film as second wiring is applicable to a thin-film magnetic head having a coil of a multi-layer structure.

    摘要： A semiconductor-type pressure transducer is disclosed in which the pressure change is detected as a resistance change by use of a bridge circuit including at least a gauge resistor changing with an external force. Each gauge resistor is made of a PN junction of a semiconductor. The pressure transducer further comprises an amplification factor compensator for cancelling the effect of the temperature change of the gauge resistors making up the bridge circuit on the amplification factor of the amplification circuit for amplifying the output of the bridge circuit.

    摘要： A current source device controls a rate of change of current flowing through a load so that the change rate of the current is equal to a change rate of a fluctuating supply voltage. A first transistor is fed with the supply voltage via a first resistor connected to its collector and a second resistor connected to its emitter. A second transistor has a base connected to a base of the first transistor, an emitter connected to a third resistor and a collector connected to a load. A current to the load is fed from the supply voltage via the load, the collector and emitter of the second transistor and the third resistor. The collector and base of the first transistor are respectively connected to a base and an emitter of a third transistor having a collector fed with the supply voltage. The ratio between a voltage drop caused across the second resistor by a reference current flowing through the first resistor, the collector and emitter of the first transistor and the second resistor, and a voltage drop caused across the third resistor by an emitter current of the second transistor, which is substantially equal to a collector current of the second transistor flowing through the load, is set to a predetermined value. The emitter area of the second transistor is enlarged beyond that of the first transistor to obtain a sufficiently large output current.

    摘要： A pressure transducer is disclosed comprising a pressure sensor portion having gage resistors in bridge formed on a thin diaphragm of a semiconductor substrate, and a power supply connected to the pressure sensor portion for driving the pressure sensor. The power supply includes a first current source for supplying a temperature-dependent current equivalent to the sum of a current almost proportional to the absolute temperature and a current independent of temperature, and a second current source for sinking the current almost proportional to the temperature characteristic of the gage resistors from the current of the first current source. A temperature compensation circuit is additionally provided to drive the bridge circuit by the difference between the temperature-dependent current and the current proportional to the temperature characteristic in a constant-current driving mode, and by a voltage proportional to the current difference when the output of the bridge circuit is connected to an amplifier whose gain is dependent on temperature.

    摘要： A magnetoelectric conversion element comprises a magnetoresistive effect material having a closed domain structure, a pair of contacts for supply of current flowing through the magnetoresistive effect material, and a bias electrode disposed between the contacts for biasing the direction of the current flow. The bias electrode is disposed so that the respective angles of intersection between the directions of current flow through different magnetic domains of the magnetoresistive effect material biased by the bias electrode and the directions of spontaneous magnetization biased by an external magnetic field are both increased or decreased.
