  • Patent number: 10756354
    Abstract: A membrane catalyst layer assembly production method is provided for producing a membrane catalyst layer assembly by discharging catalyst ink having a solvent and a solid component onto an electrolyte membrane. The membrane catalyst layer assembly production method includes forming a first catalyst ink layer having a first porosity on the electrolyte membrane by controlling a porosity of a catalyst ink layer that is formed by the catalyst ink making impact with the electrolyte membrane by adjusting an amount of solvent in the catalyst ink in drop form prior to impact with the electrolyte membrane, and forming a second catalyst ink layer having a second porosity, which is different from the first porosity, on the first catalyst ink layer, by adjusting the amount of solvent in the catalyst ink in drop form prior to impact with the first catalyst ink layer.

  • Patent number: 6688974
    Abstract: Erroneous input is prevented on the event of input of instructions by a game player, which instructions are likely to change according to the state of a game character's abilities, while providing the player with a firm grasp of the state of abilities of the character. In a competitive action game which mimics baseball, among the players operating two connected portable game devices, the player engaged in defense is prompted to select a pitch type for pitching from a pitcher character 450 to a batter character 460. Here pitching ability data is set such that the pitcher character 450 can pitch, as breaking pitches, a sinker, curveball, or slider, with a curve width of 3, 1 and 5, respectively; based on this pitching ability data, the icons 403, 404, 405 are displayed in the vicinity of the strike zone display 410.

  • Patent number: 6679774
    Abstract: A character is trained to have abilities and characteristics desired by the player, on a probability basis, without significantly reflecting the level of game playing skill of the player. A main character and game images are displayed on a monitor, and a main character is caused to move to various battle fronts by commands from an operating section. Training for increasing various ability values is performed by executing prescribed tasks. A ROM cassette stores scene images, actions for each scene, and abilities, in accordance with the success or failure of action results. The character can implement actions with a prescribed success probability, according to one specified scene. Plus or minus points are applied to the corresponding ability values in accordance with the success or failure of the action result, and actions are implemented at each one of successively selected scenes until a game time period has been cleared.

  • Patent number: 6527637
    Abstract: A game image representing an infield as a specific game image in a game space of a baseball game is displayed on a display surface of a monitor 5 as a reference game image. According to the position of a game medium character, for example, representing a baseball which serves as a game situation, the display of the reference game is switched to that of a combined game image. For example, if the ball flies in a direction toward an outfield (outfield direction), the outfield neighboring a partial game image displayed in the half of the display surface in the outfield direction within the reference game image is displayed as an adjacent game image instead of the partial game image. Accordingly, a game situation and a game progress can be easily grasped and a game operation can be more smoothly performed.
