IPC: G08G1/08
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To simply prepare plural traffic control patterns from one reference traffic control pattern. SOLUTION: When a walker sense signal is outputted from a walker pushbutton 3 and a vehicle sense signal is outputted from a vehicle sensor 4, a CPU 5 stores both the sense signals in a buffer memory 7, and when one or both of the sense signals have been stored or are stored in the memory 7, outputs a stepping command signal for stepping forward from a prescribed step to a succeeding step in the steps of a previously set reference traffic control pattern or a skip command signal for skipping operation to a specified step in accordance with the passage time of a main road side, a walker side, or an intersect road side which is stored in a program memory 6. Thereby a lamp control circuit 8 reads out a lamp display pattern corresponding to the step number specified by the stepping command signal or the skip command signal from a lamp display pattern storing part 1 and displays signal lamps 21 to 2e by lamp colors, flashing or the like corresponding to the lamp display pattern.

Title: Operation switch judging apparatus and operation switch
Inventor: ANDO ATSUSHI
IPC: G01R31/02
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To provide an operation switch with a less possibility of malfunctioning even when a foreign matter such as water infiltrates. SOLUTION: Two comparison voltages for judging changes in input voltage are prepared as criterion value 1 and criterion value 2 lower than the criterion value 1. In the state where the input voltage lowers with the depressing of an operation switch, the criterion value 2 is used as comparison voltage. At the time T1 when the input voltage lowers below the criterion value 2, an output signal changes from 'OFF' to 'ON'. On the other hand, in the state where the input voltage increases, the voltage of the criterion value 1 is adopted as comparison voltage. In other words, for the first time when the input voltage rises and exceeds a voltage level of the criterion value 1, the output signal changes to 'OFF' from 'ON'.  This prevents malfunction of the operation switch as caused by an intermediate input voltage generated between the criterion value 1 and the criterion value 2 attributed to the infiltration of water or the like.
