A power supply device includes a power supply circuit, a casing, a mold resin and a grounding member. The casing is conductive. At least part of a circuit portion of the power supply circuit is stored in the casing. A resin injector is formed in the casing. A mold resin is injected from the resin injector to fill the casing and enclose the circuit portion. The grounding member is conductive. The grounding member is arranged in the casing to shield the resin injector from the circuit portion while being in contact with the mold resin.

An X-ray tube includes a housing, an electron gun that emits an electron beam inside the housing, a target that generates an X-ray upon an incidence of the electron beam inside the housing, and a window member that seals an opening of the housing and that transmits the X-ray. The window member is formed in a plate shape from a single crystal diamond. A [100] direction of the single crystal diamond is in an intersection relationship with a thickness direction of the window member at an angle of less than 45 degrees.

An ultra-high vacuum seal assembly includes a circuit board, a first ring, and a second ring. The first ring and the second ring include indium. The circuit board includes a first surface and a second surface that is opposite the first surface. The circuit board also includes a via array that is in electrical communication with the first surface and the second surface of the circuit board. The first ring is positioned directly on the first surface of the circuit board and the second ring is positioned directly on the second surface of the circuit board.

A fluoroelastomer is formed by polymerizing a reaction mixture that comprises vinyl-functionalized silica cages, tetrafluoroethylene, a perfluoroalkyl vinyl ether, a curative, and a polymerization initiator. The fluoroelastomer has excellent chemical resistance and thermal resistance, and is suitable for use in plasma treatment systems in sealing applications. The fluoroelastomer has reduced particle formation as erosion occurs over time.
