  • Patent number: 10668811
    Abstract: A power supply system (120) according to an embodiment of the present invention includes a first power supply device (121), a second power supply device (122), and an addition circuit (123). The first power supply device (121) includes a first driving circuit that outputs a first direct current from a first power supply input and a first control circuit that controls the first driving circuit. The second power supply device (122) includes a second driving circuit that outputs a second direct current from a second power supply input and a second control circuit that monitors the first driving circuit and controls the second driving circuit. The addition circuit (123) is connected to an output terminal of each of the first and second power supply devices (121, 122) and outputs a third direct current that is a value obtained by adding the first and second direct currents to a load device (on-board illumination device (110)).

  • Patent number: 7934992
    Abstract: A game machine which uses play items such as cards and which enables the player to play a game seriously and to concentrate in the game so as to win over the opponent is provided according to the present invention. The game machine controls the progress of a game based on data read out from the play items, and issues a new play item for each game played. The game machine includes means for setting a game fee at a discount rate in accordance with the number of previous consecutive wins for the player to try a next post-victory bonus game after winning one game, and means for determining the number of games played based on the outcome (win or loss) of the player's previous games and for issuing new play items collectively to the player by the number corresponding to the determined number of games played.

  • Publication number: 20060157526
    Abstract: A motor is driven according to a total feeding amount of a recording paper calculated based on the number of prints. When a gear is rotated in a counterclockwise direction, an end of a coil spring is moved upward and a retaining arm is rotated. A tip of a separation plate fixed to the retaining arm is moved to a contact position in which the tip contacts an outer peripheral surface of a paper roll. The separation plate presses the outer peripheral surface with a constant pressing force by a coil spring. When the paper roll is rotated, the separation plate separates a paper end. Thereafter, the gear is rotated in a clockwise direction to move the end of the coil spring downward so that the separation plate moves to a retracting position away from the outer peripheral surface. During printing, the separation plate is in the retracting position.
