  • Publication number: 20090325697
    Abstract: In the game program, playing teams in a competition game played by a CPU are determined by operation of a controller of the player through an playing team determining unit. An opening demonstration video of the competition game between the playing teams determined by the playing team determining unit is determined by the CPU, through an opening demonstration video determining unit. The opening demonstration video determined by the opening demonstration video determining unit is displayed or played back on a monitor by the CPU through an opening demonstration video display/playback unit prior to the start of a competition game. In this game program, after a virtual competition game is played by the CPU, a highlight scene in the virtual competition game that satisfies a predetermined highlight condition is determined from within the virtual competition game by a highlight scene determining unit.

  • Publication number: 20090221373
    Abstract: A player can be prevented from successively using an object that affects the outcome of a match in a network competition game executed among a plurality of clients via a network. An object is selected at the end of a match event of competition game by a client on the basis of action frequency of an object that has participated in a match event. Next, a notification about the object selected at this point is sent to a server and the object is managed in the server as an object that can not appear in a new match event. A notification about the object being managed in the server is sent to the client if a new match event is to be executed in the client. At this point, the client executes a process for selecting an object from among a plurality of objects excluding the notified object.

  • Publication number: 20090034477
    Abstract: Terminal devices F and G store statistical information related to interference from an external communication system, and notify the stored statistical information to a master station E. The master station E determines the terminal device G as a candidate station for a master station capability handover destination based on collected statistical information. The master station E requests to hand over a master station capability to the terminal device G. If it is determined that the terminal device G accepts handover of the master station capability, the terminal device G starts to act as the master station.

  • Patent number: 7460555
    Abstract: When operating as a control terminal and recognizing interference from another logical network, a terminal apparatus determines whether or not a logical network to be controlled is unified with the other logical network. When unification is determined, the terminal apparatus determines whether a control terminal of a logical network newly created by unification is the terminal apparatus or a control terminal of the other logical network.

  • Publication number: 20080213705
    Abstract: A pattern exposure method and a pattern exposure apparatus in which the throughput is improved with an inexpensive apparatus and without a low running cost. Output faces of a plurality of laser beams emitted from a plurality of semiconductor lasers respectively are arranged in two directions. One of the directions is the same direction as the scanning direction of a polygon mirror while the other is a direction crossing the scanning direction of the polygon mirror. In this event, the array pitch of the output faces arranged in the direction crossing the scanning direction of the polygon mirror is made equal to resolution of an exposure pattern. In this event, the wavelength of each laser may be made not longer than 410 nm.

  • Publication number: 20080123594
    Abstract: A communication band is divided into: a beacon period in which every master station transmits a beacon packet in competition with one another; a guaranteed-band period (e.g., a TDMA period or an FDMA period) in which only a specific permitted station is allowed access; and a CSMA period in which every station is allowed access in competition with one another. Plural master stations exchange information of a communication band used in the guaranteed-band period with each other, and based on the respective information, a communication band available to the master station's own communications system in the guaranteed-band period is calculated.

  • Publication number: 20080117882
    Abstract: A communication bandwidth is divided into a beacon period in which all master stations compete for transmission of a beacon packet, a first carrier sense multiple access (CSMA) period in which only authorized specific stations are allowed to compete for access, and a second CSMA period in which all stations are allowed to compete for access. The master stations exchange information with each other about a communication bandwidth being used in the first CSMA period, thereby calculating a communication bandwidth which can be used by each communication system in the first CSMA period, based on the information.
