Abstract: An agitation apparatus (100) has a substantially cylindrically shaped agitation vessel (102); a rotation shaft (150) provided along the central axis of the agitation vessel (102); a substantially cylindrically shaped agitation member (104) having an outer diameter smaller than the inner diameter of the agitation vessel (102) and being fitted to the rotation shaft (150) so as to rotate concentrically with an inner circumferential surface of the agitation vessel (102); and a plurality of through holes (162, 164) formed through the agitation member (104) in radial directions of the agitation member. In the agitation apparatus (100), a gap between the inner circumferential surface of the agitation vessel (102) and the outer circumferential surface of the agitation member (104) is partially varied along a vertical direction of the agitation member (104).

To the rotation shaft (150), a substantially cylindrically shaped agitation member (104) is attached. The agitation member (104) has an outer diameter smaller than the inner diameter of the agitation vessel (102), and rotates concentrically with the inner circumferential surface of the agitation vessel (102). The agitation member (104) has a plurality of through holes (162, 164) formed in radial directions therethrough. The through holes (164) formed in an upper portion of the agitation member (104) are larger than the through holes (162) formed in a lower portion of the agitation member (104).

Abstract: A video game is played on a video game system by moving objects successively introduced into a game field in one direction on a display screen, determining whether a leading object or a leading cluster of objects introduced into the game field reach a predetermined position in the display screen or a memory, and ending the video game if the leading object or the leading cluster of objects introduced into the game field reaches the predetermined position. It is determined whether objects of one type are successively connected in the game field or not. The objects of one type are removed from the game field if they are successively connected in the game field. An object present ahead of the removed objects in the direction is moved in a direction opposite to the direction. An object indicated by a cursor is exchanged for an object present in the game field.
