PURPOSE:To improve the control accuracy, by delaying the rise of a control signal and reducing the time of duration of the delay. CONSTITUTION:An operation input signal (a) is fed to a control part 2, by turning on or off an optional open command switch 1a or a close command switch 1b. Then the signal (a) is encoded at a transmitting part 3 and transmitted (b) to a part 4 to be controlled. The coded signal (a) is received and decoded at a receiving part 5 at the part 4 to obtain a control signal (c). A valve 6 is opened and closed by the signal (c). In this case, a timer circuit 7 is provided at the part 4. Then the rise of the decoded signal (c) is delayed by the timer circuit 7. The duration time d4 of the signal (c) is reduced down a time obtained with subtraction of a delay time d2. This system improves the control accuracy. |
