Abstract: A control unit mainly includes game condition judging means, moving period determining means for determining a moving period T0 of a ball object, first operation response period determining means for determining a first operation response period T1 of a bat object, which begins at a first operation response start opportunity St1 preceding a pitching end opportunity E0 of the moving period T0, second operation response period determining means for determining a second operation response period T2 of the bat object, which begins at a second operation response start opportunity St2 succeeding the first operation response start opportunity St1, operation input opportunity receiving means for receiving a operation input opportunity HP of a controller, and operation opportunity response judging means for judging whether the operation input opportunity HP is included in either the first operation response period T1 or the second operation response period T2.

Abstract: In this game program, a character and a moving object when the game space is viewed from a first direction is displayed on an image display unit in the position of the character and the position of the moving object recognized by a control unit. Then, whether or not the moving direction of the moving object has changed due to a movement of the character displayed on the image display unit is judged by the control unit. If the control unit judged that the moving direction of the moving object has changed due to a movement of the character, a character near the path of the moving object determined by the changed moving direction of the moving object is recognized by the control unit as the first object character. Then, information corresponding to the first object character is displayed on the image display unit.

Abstract: The video game character role giving section gives predetermined roles to avoid overlapping the roles. The team member determining section determines a team, as “Team A” to which a “manager character”, a “catcher character” and a “pitcher character” that are operated by first, second and third players respectively. The video game character operating section allows the first, second and third players to operate the “manager character”, the “catcher character” and the “pitcher character” so that “Team A” to which the “manager character”, the “catcher character” and the “pitcher character” belong can play a game against “Team B” that is operated and controlled by a CPU.

Abstract: The present invention is for easily drawing a polygon model having borderlines at high-speed. The video game machine comprises a recording medium 200 for enlarging the 3-D model where a normal vector of each polygon faces the outside at a predetermined enlargement ratio, overlaying a back model, where a normal vector of each polygon faces the inside, onto the above model and storing the integrated model as a framed model in advance, and a drawing processor 10 for drawing only polygons facing the direction of the view point position of the virtual camera in a virtual game space on the monitor 22 based on the drawing instructions of the framed model.

Abstract: There is here provided a method for manufacturing silane by subjecting a raw material, trialkoxysilane, to a disproportionation reaction in the gaseous phase in the presence of a catalyst which is an oxide of a metal in the third period of the periodic table. According to the present invention, silane can be obtained effectively without any by-products, and the reaction can be easily controlled and stopped promptly in an emergency.
