Inventor: KAMINKOW JOSEPH E
IPC: G07F1/00
Filed: 2002-09-27
Abstract: A gaming device (10a) includes reel symbols (34) having a transformation probability. The game begins when a plurality of reels are activated (102). A plurality of symbols are randomly generated and displayed (104). Upon a game - triggering event, the processor determines the transformation probability of a symbol displayed on gaming device (106). The processor then randomly determines whether to transform a symbol based on the transformation probability associated with that symbol (108). The processor transforms the symbol if the symbol is determined to be transformed (110). The processor makes an evaluation to determine if there are any winning combinations displayed on the gaming device (112). Upon determining the transformation probability for each symbol, the game ends (114).

Patent CA-2504126-A1 (CA)
Inventor: FUKUI NOBUYUKI
IPC: C12G3/02
Filed: 2003-11-07
Abstract: It is a common problem in producing fermented drinks to prevent or regulate off-flavor (unpleasant smell) generated in the course of fermentation using yeasts. Thus, it is intended to provide a process for producing a fermented drink having a favorable taste with lessened off-flavor wherein a low alcoholic drink is produced by the fermentation stopping method. By controlling the L-methionine concentration and the free amino nitrogen (FAN) level of a sugar solution, it becomes possible to produce a fermented drink having a lowered hydrogen sulfide concentration and T-VDK concentration and showing relieved off-flavor, i.e., sulfur smell and diacetyl smell.
