Filed: 2006-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a game becomes monotonous and a player gets bored due to the lack of variation of a game wherein a replay winning probability is increased after the end of a special game in the conventional pachinko slot machine.  <P>SOLUTION: A sub CPU 82 discriminates whether or not a mini game during a general game for completing a calculation formula for deriving a prescribed value is a success (S453), and in the case of the success, subtracts a compensation value from an internal point counter and adds the compensation value to a navigation point counter (S454). In failure, an internal point counter subtraction value is subtracted from the internal point counter (S455). On the basis of the game result of a failure or a success in the mini game during the general game and navigation points imparted to the player for the success in the mini game during the general game, it is reported that a specified symbol combination such as the small prize pattern of red cherries or the small prize pattern of blue cherries is determined as a winning symbol combination in the state under an RT1 operation after the end of a bonus game.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: A seat, especially an airplane or vehicle seat, has a seat part placed on the stand-type seat structure (12) in relation to a base and provided with a bearing part (18) on its front side. The bearing part (18) is embodied in a flexible manner and can move in the direction of the seat structure (12) when a predefined seating load is exerted on it. When the load is discharged, it can move back into its initial position in the opposite direction from the seat structure (12). This arrangement creates a seat whose front part is maintained in a flexible manner such that the front area of the seat part yields according to the seating load exerted by the seat user. The pressure forces are limited to the lower side of the upper thighs of the seat user. As a result, the cross-sections of the veins in that region are not reduced, but are maintained such that the circulation of the blood is not impeded, significantly reducing the risk of thrombosis.
