  • Publication number: 20070281791
    Abstract: To continue, in a communication game system configured of three or more terminal devices, a game with remaining terminal devices when a communication of a portion of the terminal devices has been cut off, without preparing a surplus terminal device. Four game machines implement a game by alternating one turn each. Each game machine, on its own turn, as well as implementing the game on the relevant turn based on an input thereof, transmits game progress information based on the relevant input, and turn determination information indicating a determination of the relevant turn, to other game machines. The game is implemented in accordance with the game progress information and turn determination information received from the other game machines.

  • Patent number: 6149860
    Abstract: A carburization and quenching apparatus includes: a plurality of carburizing chambers for carburizing thin plate parts; a gas cooling chamber for cooling the thin plate parts carburized in the carburizing chambers; and a reservoir tank 3 connected to the gas cooling chamber for delivering a cooling gas into the gas cooling chamber. The plurality of carburizing chambers are positioned at an approximately equal distance from the gas cooling chamber to surround the gas cooling chamber.In a continuous furnace, thin plate parts can be transported successively at least between a carburizing chamber and a pressurized cooling chamber. The thin plate parts are carburized in the carburizing chamber and then rapidly quenched in the pressurized cooling chamber by cooling the thin plate parts with a pressurized gas which can be e.g. inert gas.

  • Patent number: 5667603
    Abstract: A process for hardening a plurality of holed flat parts. The holed flat parts are heated by inserting a cantilever hanger into the holes of the holed flat parts to support them in vertical positions within a furnace. The holed flat parts are then removed from the hanger by inserting a moving fork into the holes of the holed flat parts and moved to a cooling section while being supported in the vertical positions on the moving fork. Then, the holed flat parts in the vertical positions are quenched in the cooling section by blowing a gas downward to them. Also disclosed is an apparatus for practicing the holed flat part hardening process.

  • Patent number: 5581410
    Abstract: A resin-coupled lens has a resin layer on at least one surface of the lens and has a light-shielding membrane, wherein the edge surface of the outermost perimeter of the resin layer is covered by the light shielding membrane. A production method for the resin-coupled lens includes a resin layer formation process that forms a resin layer on at least one surface of the base material of the lens, a light-shielding membrane formation process that forms a light-shielding membrane on the edge surface of the outermost perimeter of the resin layer by applying a light-shielding coating, and a reflection-preventing membrane formation processes that forms a reflection-preventing membrane at least on the surface of the resin layer.

  • Patent number: 4318603
    Abstract: A film rewind device in a camera in which a rewind coupling is automatically engaged with a cassette shaft in response to rewind operation has a rotatable member having a spiral groove on its peripheral wall portion and said rewind coupling at the end of the shaft thereof, the rotatable member being slidable in axial direction and rotatable by rewind operation, and a meshing member meshing with the spiral groove at the initial stage of the rewind operation to thereby slide the rotatable member in axial direction to cause the coupling to engage the cassette shaft. The mesh engagement between the meshing member and the spiral groove is released in axial direction when the coupling engages the cassette shaft, so that the meshing member comes to support the rotatable member so as to block the return of the rotatable member in axial direction.
