IPC: A63F7/02
Filed: 2001-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent mistakes resulting from a difference in condition between different kinds of symbols used in displaying jackpot symbols. SOLUTION: Plural kinds of jackpot symbols are displayed in such a way that the portions needed to distinguish the symbols from one another (the figure itself of each figure symbol FG constituting each jackpot symbol) can be distinguished from one another, while the other portions (the bordering color C1 of each figure, inside color C2, the shape of a rectangular portion SQ, and the color C3 of the rectangular portion SQ) are the same. Thus, there is no difference between one jackpot symbol, say, 777, and another jackpot symbol, say, 666 (or other jackpot symbols) (that is, one symbol does not appear to have advantages over another symbol). Even if a jackpot symbol such as 333 or 777 is displayed, there is no fear that the player mistakes it as indicating a bonus game.

Title: Traveling control system for vehicle
Inventor: KISHI YASUHISA
IPC: B60W30/00
Filed: 2001-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a traveling control system for a vehicle, by which a driven can perform an appropriate traveling control in response to a cut-in onto driver' s lane or lane change by a vehicle traveling on the lane adjacent to the lane on which driver's own vehicle is traveling. SOLUTION: While the traveling control system controls the traveling of driver's own vehicle so that the vehicle-to-vehicle distance between driver's own vehicle and other preceding vehicle traveling on the same lane is properly maintained, other vehicle traveling on the lane adjacent to driver's lane may intrude into driver's own lane in avoiding another vehicle or object on the same lane, or cuts in onto driver's own lane in trying to change the lane. The traveling control system estimate the possibility and location of the above behaviors to occur, and, according to a result of the estimation, controls the driver's own vehicle speed and the vehicle-to-vehicle distance to the preceding vehicle.  Thus the driver's own vehicle can respond quickly and appropriately to the sudden cut-in onto driver's own lane or lane change by the other vehicle traveling on the adjacent lane, preventing an uneasy feeling from occurring in the driver or other occupants.
