  • Gaming machine, method and program for providing a game
    Patent number: 10121329
    Abstract: To provide a gaming machine that can provide a new type of game that maintains or improves the interest of a player, and a method and program for providing a game. In the gaming machine 1, by removing symbols of a particular type and moving a following symbol, the ratio of symbols of types other than the particular type becomes higher in the symbol array formed on the display unit 27, and it is easier for the symbol array to configure a winning combination. Because the chance of winning is higher after the particular type of symbol is removed in this manner, it is possible to provide a new type of game where the interest of the player can be maintained or improved after the symbols are removed.

  • Stepping motor control device, component mounting machine provided with stepping motor control device, and stepping motor control method
    Patent number: 10110148
    Abstract: A stepping motor control device is provided with a stopping position determination section and a drive control section. The stopping position determination section determines whether a mover stopping position during the holding state is a stabilized phase or a semistable phase. When it is determined that the mover stopping position is a semistable phase during the holding state by the stopping position determination section, and the control state of the stepping motor transitions from the holding state to the standby state in which the holding of the mover is released due to a trigger signal from a device or the holding state persisting for a fixed time, the drive control section changes the mover stopping position to one of the stabilized phases adjacent to the mover stopping position during the holding state.

  • COMMUNICATION GAME SYSTEM, GAME APPARATUS, SERVER, STORAGE MEDIUM STORING A PROGRAM, AND GAME CONTROL METHOD
    Publication number: 20180256983
    Abstract: A communication game system includes a plurality of game apparatuses which are able to wirelessly communicate with each other. Each of the game apparatus registers identifying information of an opponent obtained by a short-distance wireless communication or by user's manual input in a friend list. Thereafter, the game apparatus connects to the Internet, and inquires whether it is possible to communicate with an opponent in the friend list over the network. If it is possible to communicate, the game apparatus obtains an address of the opponent to make a network communication. Even if a user makes a short distance wireless communication with a friend to exchange and register the identifying information or registers the friend by hand and then is parted from the friend, the user can safely communicate with the friend across the network without being exposed to unknown players.
