Abstract: A compression loaded semiconductor device package (40) in accordance with the invention includes a cylindrical semiconductor device (54) having a first region (66) on a first face, a control region (68) on the first face having a central portion (70) and a plurality of projections (72) extending radially from the central portion with the radial projections being symmetrically disposed around the periphery of the first face and a second region (74) on a second face with the second face being opposed to the first face; an electrically conductive contract (48) having an external control terminal (88), an annulus (84) electrically connected to the external control terminal, a plurality of projections (82) electrically connected to the annulus, projecting radially inward and a center (80) electrically connected to the radially inward projections and to the control region; and first and second annular insulators (112 and 114) each insulator having a plurality of faces, the upper cover being bonded to a first face (

Abstract: Apparatus and method for sterilizing articles includes a sealed first enclosure made at least partially of a gas-permeable plastic film and a sealed container releasably containing a gaseous sterilant under pressure, the container being enclosed within the first enclosure. An openable second enclosure made at least partially of a gas-permeable plastic film is also provided and the first enclosure and the articles to be sterilized are disposed in the second enclosure. The sterilant which is characterized by toxicity and flammability when released from its container diffuses from the first enclosure into the second enclosure at a rate capable of establishing sterilization conditions in the second enclosure during a sterilization cycle to thereby effect sterilization of the articles in the second enclosure. A third enclosure is also provided in which the second enclosure containing the articles to be sterilized is disposed.

Abstract: A fitting that is adapted for use between two adjacent frame members that are mechanically isolated from one another. The fitting has two flanged members one fixed to each frame member and a pressurized liquid coolant flow channel with a pair of bellows units on opposite sides of an intermediate ring that is loosely mounted on the outer surface of a spool attached to one member.
