  • Publication number: 20160284431
    Abstract: To provide a containment cask for storage or transport of radioactive material, without employing a homogenization treatment. Pouring a molten lead between an inner shell 2 and an intermediate shell 3 to serve as a gamma ray shielding material, allowing the lead to cool, and subsequently, filling either one or both of a first void layer 9a formed at a boundary between the inner shell 2 and the poured lead 5a or a second void layer 9b formed at a boundary between the intermediate shell 3 and the poured lead 5a, using a low melting point metal 10 in a closely adhering state. To provide the cask 1 with a good heat-dissipating effect, by filling the void layers 9a, 9b that prevent the cask 1 from dissipating heat, with the low melting point metal 10 that has a superb thermal conductivity.

  • Publication number: 20160100321
    Abstract: A use management apparatus includes a calculation unit that calculates an input level to an amplifier that amplifies a first signal transmitted from a transmitter station of a primary system, the input level being calculated by adding second field intensity of a second signal to first field intensity of the first signal, the second signal being transmitted from a transmitter station of a secondary system with use of a white space of the primary system, and a use propriety determination unit that authorizes the secondary system to use the white space when the input level is less than a saturation input level of the amplifier.

  • Publication number: 20150300535
    Abstract: A pipe with a pipe main body made from fiber reinforced plastic and a connection portion made from resin and having substantially tubular shape, into which an end portion of the pipe main body is inserted, thereby being fixed to the end portion. The connection portion includes an annular cover portion that covers an end face of the pipe main body, and an external tapered male screw portion. When the pipe main body is connected to another pipe main body, the male screw portion is screwed with a substantially tubular tapered female screw portion of a coupling. The pipe has a tubular-shaped front-end protrusion located beyond a front-end portion of the male screw portion. The front-end protrusion includes a region of the pipe main body. The entire circumferential region of the pipe in the vicinity of the front-end portion is reinforced by the front-end protrusion.

  • Publication number: 20150075663
    Abstract: A pipe includes a tubular reinforced fiber structure, and a tubular matrix resin pipe main body centered on the central axis, together with a reinforced fiber structure, covering an internal side of the reinforced fiber structure on the central axis side, and an external side. An external end surface of the pipe main body has an inclined surface whose diameter is gradually reduced toward the end face, which connects the pipe main body to another pipe main body, with the main body inclined surface coupled to a substantially tubular-shaped coupling. A portion of the reinforced fiber structure near the main body inclined surface has a plurality of fiber bundles extending in parallel to the central axis. This prevents a shear failure of the fiber bundles of the reinforced fiber structure of the main body inclined surface.

  • Patent number: 8946889
    Abstract: A semiconductor module is provided which includes a semiconductor unit which is made by a resin mold. The resin mold has formed therein a coolant path through which a coolant flows to cool a semiconductor chip embedded in the resin mold. The resin mold also includes heat spreaders, and electric terminals embedded therein. Each of the heat spreaders has a fin heat sink exposed to the flow of the coolant. The fin heat sink is welded to a surface of each of the heat spreaders through an insulator, thus minimizing an electrical leakage from the heat spreader to the coolant.

  • Publication number: 20140193202
    Abstract: To make it possible to raise a door body even if it is damaged by an impact of vehicle traffic or falling objects when it is in a lowered state, and to keep the door body in a raised state even if it is damaged by a water pressure of a tsunami or a high tide when it is in a raised state. A door body 2 of a floating flap gate 1 is disposed at an opening or at an access way. When water flows in, a forward end 2b of which swings upwards, in a direction in which the water flows in and within a plane in a height direction, around a base end 2a thereof which serves as a center of rotation, to block the opening or the access way. The door body 2 is formed from a hard polyurethane foam 4 in the form of a sheet.

  • Patent number: 8555695
    Abstract: A battery unit is housed in a metallic battery case. In the battery unit, current collectors having bent portions on both sides are fixed to face surfaces of an electrode plate group of a prismatic battery. The portions of the battery case, which correspond to the bent portions, are pressed in a thickness direction. Under the pressure, a short circuit inspection for a short circuit between the battery case and the current collectors of the battery unit is executed. When a projected object exists on the bent portion, a short circuit is generated between the battery case and the current collector by pressing so that a short circuit failure caused by a shape of the current collector can be detected.

  • Patent number: 8217658
    Abstract: An object of the present invention is to easily detect a short circuit failure in a current collector of a prismatic battery and prevent a short circuit caused by an existence of a burr generated while cutting or a spatter generated while welding the current collector to an electrode plate. A battery unit is housed in a metallic battery case. In the battery unit, current collectors having bent portions on both sides are fixed to face surfaces of an electrode plate group of a prismatic battery. The portions of the battery case, which correspond to the bent portions, are pressed in a thickness direction.
