Abstract: In a metal housing of the "Flameproof Enclosure" ignition protection type, one part of the housing is provided at the parting plane with a rib and the other housing part is provided with a groove complementary thereto. The cross-sectional dimensions of the groove are larger than the cross-sectional dimensions of the rib. The gap-like space obtained thereby is filled with a coating which adheres integrally either to the rib or to the walls of the groove. This gives rise, between the coating and the other part to which it does not adhere integrally, to a gap which meets the requirement placed on an "ex-gap" of a flameproof housing.

Abstract: A liquid cooling module for semiconductor chips is disclosed. The module includes a plurality of substrates, each containing at least one chip. The substrates are arranged in the module so that when coolant flows through the module, the coolant is exposed to the top and bottom surfaces of the chips. A gasket is used between each substrate. The gasket is made if a Z-axis elastromeric material that is impervious to liquid and therefore directs the flow of the coolant in the module and makes the module liquid tight. The material also is conductive in the Z direction, but not the X or Y direction, thereby making electrical communication between the chips on different substrate levels possible. The module is intended to be attached to a circuit board, thus simplifying the layout of liquid cooled chips on the board.

Abstract: With an accelerator for accelerating an electron beam by a voltage of about 400 KV having a stability of 10.sup.-6, it is difficult to use a flexible, insulated cable to feed the output from a power supply to an electron beam and an accelerating tube. Accordingly, the present invention employs a rodlike connector instead of such an insulated cable. A guide means is provided to permit the movement of a power supply column in the direction of the axis of the connector. This facilitates cleaning or otherwise maintaining the power supply column, the electron gun, and the accelerating tube.
