    • An X-ray generator with current measuring device has an X-ray tube, a power supply unit for feeding high voltage to the X-ray tube, a high voltage cable for connecting the X-ray tube and power supply unit. The high voltage cable is comprised of a core conductor, an insulating layer surrounding the core conductor and a covered shield surrounding the insulating layer and the covered shield is disconnected near one end of the cable connected to the X-ray tube so as to be divided into a major shield portion adjacent to the power supply unit and a minor shield portion adjacent to the X-ray tube. An insulating member is provided for electrically insulating the major and minor shield portions, and a magnetic sensor sensitive to a magnetic field generated by a current flowing through the high voltage cable is positioned around the minor shield portion. The X-ray generator can measure the X-ray tube current accurately and readily under electrical insulation.

    • A waveguide filter for use in a microwave oven having a plurality of metallic plates disposed in a waveguide in substantially parallel to side walls of the waveguide. The metallic plates are provided in the upper and lower edges thereof with a series of openings at a constant interval so as to provide a corrugated configuration. First members are disposed for providing a certain spacing between adjacent ones of the metallic plates and holding the metallic plates substantially in parallel to one another; and second members including metal members are disposed between the side walls of said waveguide and the ones of the metallic plates adjacent the waveguide side walls for creating a substantially uniform clearance between the upper and lower edges of the metallic plates and the upper and lower walls of the waveguide and for holding the metallic plates substantially in parallel to the waveguide side walls.
