  • Patent number: 10377851
    Abstract: A resin does not need to incorporate a fluorescent substance and exhibits fluorescence itself. Also, a liquid crystal polymer is provided which does not contain a bleeding out substance such as hydrophobic silica and barium sulfate and which has an effect of suppressing fibrillation in the resin itself. A liquid crystal polymer includes a copolymer of a polymerizable monomer (A) selected from the group consisting of pyromellitic acid or anhydride thereof and a reactive derivative thereof and a polymerizable monomer (B).

  • Patent number: 8979656
    Abstract: A game system includes multiple game machines which implement a game by alternating turns. Each game machine implements the game on its turn, and transmits game progress information to the other game machines. The game is implemented in accordance with the transmitted game progress information. A host game machine of the game machines transmits turn determination information to the other game machines, and receives turn completion information from each of the other game machines. When the turn confirmation information is not returned from one of the other game machines, the host game machine recognizes that communication has been cut off. When the communication has been cut off, the host game machine functions as a substitute for the cut off game machine.

  • Patent number: 7607801
    Abstract: A reflection-type light emitting apparatus has an excellent heat radiation property and allows the use of a high-power light emitting element, the minimization of a reduction in radiation efficiency of reflected light, and the focused radiation of high-output light at high efficiency. The apparatus has: a case 10 of metallic material and with an excellent heat radiation property; a reflection mirror section 11 formed fitted to the lower portion of case 10; a transparent plate 12 to cover the upper surface of case 10; heat radiation plates 13, 14 of metallic material with excellent heat conductivity and inserted inside the case 10; an LED element 2 mounted on the heat radiation plate 13; lead sections 15A, 15B fixed through an insulating layer 15a to the heat radiation plate 13 to serve as a power supply member to supply power to the LED element 2; and a spacer 16 of an insulating material to insulate the lead sections 15A, 15B from the case 10.

  • 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.
