  • Patent number: 6283861
    Abstract: In a scene of a role-playing game in which the player character, whose actions are controlled by a player, fights with an enemy with one of a variety of items such as weapons, a video game device selects one item in accordance with a player's operation. The video game device obtains an effective range such as a shooting range which has been predetermined for the selected item, and displays this effective range as a hemispherical wire frame model or the like, positioning the center of the effective range at the position of the player character. The player judges the effectiveness of an attack from the displayed wire frame model. A hitting probability, the effect attained when the player attacks the enemy, such as a damage imparted on the enemy, differs depending on whether the enemy is located within the wire frame or not.

  • Patent number: 6247521
    Abstract: A melt filling pressure difference control method controls a pressure difference used to supply melt from a holding furnace to a cavity of a casting machine by generating a pressure difference between an interior space of holding furnace and the cavity formed inside the mold. The method includes the steps of setting up a program pattern comprising time-varying characteristics of pressure difference target values, controlling the pressure difference so as to follow the program pattern that was set up, detecting whether the melt surface has risen to a predetermined level inside the cavity, compensating the program pattern based on the melt surface level when the melt surface has risen to a predetermined level inside cavity, and controlling the pressure difference between space inside the holding furnace and the cavity so as to follow the compensated program pattern.

  • Patent number: 5393653
    Abstract: A method for preparing a silver halide emulsion. The method comprises supplying bromine and/or bromine ion at a plurality of processing stages to silver halide host grains to form a phase rich in silver bromide in the vicinity of the apexes of the grains. The host grains are substantially of a cube or octahedron and have a silver chloride content of about 95 mole % or more, and a silver bromide content of about 0 to about 5 mole %. The bromine and/or bromine ion is supplied at the plurality of stages by adding and mixing in a reaction vessel at least one of (i) a water soluble bromine compound, (ii) silver halide grains having a smaller average grain size and a larger silver bromide content than the silver halide host grains, and (iii) a bromine or bromine ion precursor represented by a certain formula (S). In at least one stage of the plurality of processing stages the bromine and/or bromine ion is supplied when the formation of the silver bromide-rich phase is at least 80% complete in the previous stage.
