    • 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.
    • 采用磁性检测元件。 来自磁检测元件的输出电压由放大电路放大。 开关电路连接在磁检测元件和放大电路之间。 开关电路有选择地反转来自磁检测元件的输出电压的极性,并将输出信号输入到放大电路。 比较器比较来自放大电路的输出信号和参考值以输出比较结果。 提供第一和第二存储电路以接收来自比较器的输出信号。 电力控制单元至少控制要提供给磁检测元件的电力。 第一和第二门控信号分别提供给第一和第二存储电路。 基于第一和第二选通信号的信号被提供给电力控制单元。
