Abstract: In a method for molding a resin piston by charging a preheated resin tablet into a cavity of a molding die, and by carrying out compression molding while heating, at a time point when an internal pressure of the cavity arrives at a determined pressure, by pressurizing a pressurizing margin in the molding die, resin which overflows from the molding die is discharged from a passage which is defined in an area except an outer circumferential surface of the piston, while the internal pressure of the cavity is maintained. After a thermosetting cycle has finished, the molding die 21 is opened.

Abstract: In conventional types of slot machines, the prize status is determined by random selection using random numbers for each game. In this type of conventional slot machine, for example, the current game prize status is determined by the random selection of the prize status when a token is put into the slot machine to operate the start lever. When the current game prize status is determined, the reels are rotated to begin the game. In the type of slot machine in which the prize status is determined by random selection using random numbers in the present invention, a demonstration is made by unusual lights or sounds or by unusual operations when the randomly selected prize status is a “big jackpot” or when a “big jackpot” is missed by one reel symbol among all the reels (this condition of two matching symbols is referred to as “one-shy”).

Abstract: In a game machine, game result conditions may be randomly selected for a predetermined number of games among a plurality of given game result conditions and a demonstration may be made to provide a player of the game with a feeling of higher probability of winning a prize in the game when the randomly selected game result conditions include a given specific game result condition. The demonstration may be made by a variety of possible techniques, including using a flashing light or changing the volume or tone of a sound. Random numbers may be sampled in advance for random selection of game result conditions for the current game and for one or more games that will follow the current game, i.e., ranging several games down from the current game. These random numbers may be used to determine whether or not a demonstration should be made in the current game.

Abstract: A gaming machine in which a game is controlled using virtual reels arranged to correspond to symbols of actual reels, increases the interest of a player in playing the game. A virtual symbol row arrangement is provided corresponding to a plurality of symbol rows to be displayed on a variable display, and is formed of the symbols that constitute each of the symbol rows. When a predetermined play condition is satisfied, a controller starts the operation of the variable display and samples random number values. In response to the sampled random number values, the controller determines stop symbols in the virtual symbol row arrangement for every symbol row. The controller controls the variable display to produce an image of the stop symbols when the variable display is stopped, and performs win determinations on a selected combination of the stop symbols. The virtual symbol row arrangement consists of at least two tables, with a plurality of virtual symbol rows disposed as one table.
