  • Publication number: 20140295937
    Abstract: A game device includes a first setting unit, a lottery unit, a decision unit, and a determination unit. The first setting unit sets a first character for a first player and a second character different from the first character, both belonging to a first group. The lottery unit decides stop positions of spinning slot reels of a reel group displayed on a display. The decision unit decides a battle action of the first group. The determination unit decreases hit points of an enemy character in response to the battle action and decreases hit points of at least one of the first and second characters in response to another battle action by the enemy character, so as to determine a winner based on respective remaining amounts of the hit points.

  • Publication number: 20130267364
    Abstract: A silent chain includes guide plates each of which has a cut-away portion on its inner side and a cut-away portion on its outer side for allowing elastic deformation of the guide plate in the longitudinal direction of the chain so that bowing of the connecting pins of the chain is reduced, and galling of the connecting pins and unbalance of the loads on the link plates of the chain are suppressed. The deepest parts of the respective cut-away portions are longitudinally offset from each other so that longitudinal elastic deformation can occur without impairing the tensile strength of the guide plate.

  • Patent number: 8418793
    Abstract: A motorcycle that can facilitate identification of and taking in and out of an article stored below a rear seat includes a storage box that is mounted to a body frame. The front portion of the storage box is covered by a front seat. The rear portion of the storage box is covered by the rear seat and the rear seat is surrounded by the rear spoiler. The rear spoiler has an opening portion that is almost-rectangular as viewed from above. When the rear seat is removed, an article can be put in and taken out from the storage box through the opening portion. A first seal member is attached to the bottom plate of the rear seat, and is pressed against the circumferential edge portion of the opening portion to thereby seal between the rear seat and the rear spoiler.

  • Patent number: 8412014
    Abstract: An optical fiber ribbon is capable of branching by means of any tool. The optical fiber ribbon is comprised of a plurality of optical fibers running in parallel, each of the optical fibers having an allowable radius of curvature; a blanket sheath totally covering the plurality of the optical fibers; one or more concavities formed at any one or more intermediates among the optical fibers; and slits respectively arranged in series at a regular interval along the concavities, the slits penetrating the blanket sheath and allowing the tool to be inserted and the blanket sheath to split by means of movement of the tool along the concavities. The length of each slit prior to insertion of the tool is so determined that flexures of the optical fibers induced by the tool widening the slits do not exceed the allowable radius of curvature.

  • Patent number: 8249781
    Abstract: In a vehicle seat control system (10), before a vehicle (60) turns a curve ahead of the vehicle (60), a control circuit (28) determines lateral acceleration that is expected to occur to the vehicle (60) while the vehicle (60) is turning the curve, and in addition, determines whether a braking operation is performed by a driver before the vehicle (60) turns the curve. When the control circuit (28) determines that an estimation value of the lateral acceleration is greater than a reference value, and that a braking operation has been performed by the driver before the vehicle (60) turns the curve, movable side support portions (26) in a vehicle seat (12) are pivoted in the closing or bending direction.
