Abstract: A game performing method for executing a given sports game which is proceeded by performing match-ups by a plurality of teams arranged for every game owning a plurality of player characters a plurality of times during a virtual competition period, involves varying a value of a team parameter provided for each of the teams according to how a game is proceeding; determining a change-intended team, of which configuration of owned player characters is to be changed by addition and/or release of player characters, among the plurality of teams; judging approval or disapproval of a change of a configuration of owned player characters of the change-intended team based on the current value of the team parameter of the change-intended team; and changing the configuration of the owned player characters of the change-intended team, when it is judged that the change is approved.

Abstract: A game performing method for executing a given sports game which is proceeded by performing match-ups by a plurality of teams arranged for every game by each of a plurality of groups owning a plurality of player characters a plurality of times during a virtual competition period, has: varying a value of a group parameter provided for each of the groups according to a proceeding of the game; determining a change-intended group, of which configuration of owned player characters is to be changed by addition and/or release thereof, among the plurality of groups; judging approval or disapproval of a change of a configuration of owned player characters of the change-intended group based on the value of the group parameter of the change-intended group at the moment; and changing the configuration of owned player characters of the change-intended group, when it is judged that the change is approval.

Abstract: A game performing method for executing a game in which a pitcher and a batter play a match-up, has: generating a match-up image of the pitcher and the batter; generating a graph representing preset pitching sequence data; controlling a display of the match-up image provided with the generated graph on its given area; and controlling a pitch of the pitcher automatically, based on the pitching sequence data, wherein the graph representing the pitching sequence data of the pitcher is controlled and displayed on the match-up image of the pitcher and the batter.

Abstract: An apparatus for producing a single crystal grown by Czochralski method includes a winding drum disposed in a case for winding up and down a flexible pull wire, a power transmission mechanism for driving the winding drum, and a bearing unit for rotatably supporting the winding drum. The power transmission mechanism and the bearing unit are disposed outside the case and isolated from the furnace atmosphere surrounding the winding drum and the pull wire in the case. With this construction, metallic dust produced by abrasion from the power transmission mechanism and the bearing unit has no influence on the condition of the furnace atmosphere and hence the quality of a single crystal being pulled upwardly by the pull wire.
