    摘要： A clock signal generating apparatus and method in which data recorded in a plurality of tracks and clock marks recorded at equal angular spaces at different radial distances on a rotating disk are reproduced by a reproducing head from the disk and a clock signal is generated in synchronism with the clock marks reproduced by the reproducing head by means of a discriminating circuit for detecting a synchronous state between the generated clock signal and the reproduced clock marks, a circuit for causing oscillation of the reproducing head in a radial direction of the disk over a plurality of tracks when the synchronous state discriminating circuit determines that the clock signal is not synchronous with the clock marks, and a phase-locked loop circuit for generating the clock signal in synchronism with the clock marks reproduced from the disk while the reproducing head is oscillated over the plurality of tracks by synchronizing on the clock marks reproduced at a variety of different radial positions on the disk as the disk is rotated.

    摘要： A method of manufacturing a low power dissipation semiconductor power device is provided which is easy to perform and suitable for mass production. When a first and second conductivity-type regions are formed on a semiconductor substrate which is selectively irradiated by impurity ions, an excellent super junction is formed by controlling the ion acceleration energy and the width of each irradiated region so that the first and second conductivity-type regions may have a uniform impurity distribution and a uniform width along the direction of irradiation. Another method of manufacturing a low power dissipation semiconductor power device having an excellent super junction is provided which selectively irradiates a collimated neutron beam onto a P+ silicon ingot and forms an N+ region that has a uniform impurity distribution and a uniform width along the direction of irradiation in the P+ silicon ingot.

    摘要： A magnetic detection element is employed. An output voltage from the magnetic detection element is amplified by an amplifying circuit. A switch circuit is connected between the magnetic detection element and the amplifying circuit. The switch circuit reverses the polarity of the output voltage from the magnetic detection element selectively and inputs an output signal to the amplifying circuit. A comparator compares the output signal from the amplifying circuit and a reference value to output a comparison result. First and second storage circuits are provided to receive output signal from the comparator. An electric power control unit controls at least the electric power to be provided to the magnetic detection element. First and second gated signals are provided to the first and second storage circuits respectively. A signal based on the first and second gated signals is supplied to the electric power control unit.

    摘要： A driving amount controller for reducing a response delay or erroneous deviation in control of a driving amount of a controlled system. The driving amount controller includes an ECU that increases an add-in amount to a duty ratio DUT of a control signal according to an increase in the speed variation ΔDTHR of a target opening DTRH of the throttle valve 16 when the speed variation ΔDTHR is positive. In addition, the ECU increases the add-in amount to the duty ratio DUT of the control signal according to a decrease in the speed variation ΔDTHR when the speed variation ΔDTHR is negative. A throttle valve on a vehicle is an example of the controlled system.
