Abstract: PURPOSE:To prevent the through-output of an input data caused in an FF circuit by adding a gate control circuit in which two gate control signals of a transfer gate inputted into the FF are always reverse to each other when a delay takes place between two clock signals to the flip-flop circuit. CONSTITUTION:Suppose that the level of a data IN at an in response to IN changes from L to H when a clock signal C2 and a clock signal C1d whose delay time is (d) are inputted to a gate control circuit 10. When the level of a clock signal C2 is changed from L to H at a point of time td thereafter, since a gate control signal SId is changed from L to H, the node signal S2 of a master FF 11 is changed to H. Since a gate control signal S4d goes to L at the point of time td, the input transfer gate TR 3 of a slave FF 12 is turned off, and the H level of an input data SIN is not propagated up to a master FF 11. Since an output node signal S5ad is at an L level as it is, no data through-output takes polace.

Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To realize control provided with the advantages of a one-day ticket and a conpon ticket in a gate controller using a card. SOLUTION: The accumulation of points subtracted at every gate passage is stored in a card 1 through a communication function part 4 as accumulated subtraction points.
