  • Patent number: 5701011
    Abstract: A radiographic apparatus is provided which is capable of converting an X-ray directly into an electric signal, high in resolution and detection efficiency, and easy to manufacture. On at least one surface of a compound semiconductor substrate for generating an electric charge by X-ray irradiation, a plurality of split electrodes are disposed, and electrodes are disposed on picture elements formed on a CCD corresponding to these split electrodes, and are electrically connected to CdTe as compound semiconductor substrate and the CCD. An electric current issued from the split electrodes is divided, and is partly discharged through grounding wires.

  • Patent number: 4300032
    Abstract: In an output control apparatus for a microwave oven, it is known to insert a control switch in the primary side of a power transformer of a magnetron. In this invention, the control switch is provided in the secondary side of the power transformer either in a magnetron circuit or in a rectifier circuit. The actuation of the control switch is controlled by an on-off control signal such that the control switch is opened and closed respectively within zero-current time periods, of a half-wave current which flows through the rectifier or the magnetron. A transient rush current to the transformer is reduced and reliable intermittent operation of the magnetron is assured.
