    • A magnetic field intruding into an electron lens area from outside an X-ray image tube is detected by a magnetic field sensor. A magnetic field for offsetting the magnetic field is generated by a coil arranged in an input surface area of the X-ray image tube, so that the distortion is corrected by removing the effects of the magnetic field. The magnetic field sensor is arranged in an area surrounded by a magnetic shield of the X-ray image tube and constituting an outer peripheral area on the electron lens area side distant from the input surface area of the X-ray image tube. The magnetic field sensor is such that the effects of the magnetic field generated by the coil are reduced and the magnetic field intruding into the electron lens area is accurately detected.
    • 通过磁场传感器检测从X射线图像管外部侵入电子透镜区域的磁场。 通过设置在X射线图像管的输入表面区域中的线圈产生用于抵消磁场的磁场,从而通过去除磁场的影响来校正失真。 磁场传感器配置在由X射线图像管的磁屏蔽围绕的区域中,并且构成远离X射线图像管的输入面的电子透镜区域侧的外周区域。 磁场传感器使得由线圈产生的磁场的影响减小,并且能够精确地检测侵入电子透镜区域的磁场。

    • For a control circuit of a three-phase alternating current motor-generator, which serves as a three-phase rectifier circuit for charging a battery with power generated by driving the motor-generator as a generator and which also serves as a three-phase inverter circuit for driving the motor-generator as a motor by using a battery and uses MOSFETs as control elements for each of three phases, a control device is provided, which, in case of driving the motor-generator as the three-phase ac generator, uses means for making synchronous rectification by using MOSFETs only on the negative potential side of respective phases and means for delaying and advancing an electric angle of the current carrying control timing by gate control of MOSFETs on negative potential side. When operating the motor-generator to charge the battery, this control device can easily perform the current carrying control for three-phase rectification and effectively generate a constant charging voltage without affection of variations in rotation speed and load.
