Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To allow a amount of water supply to be visually confirmed with a position of a dial during water supply by providing the dial set up the amount of water supply, a sensor detecting rotation of a turbine provided in a flow path to convert into an electrical signal, a motor recovering a cam and the dial according to the electrical signal, and an electronic control part driving a motor. SOLUTION: When a dial 5 is rotated to set up an amount of water supply, a switch 40 is tuned on. Then, an electronic control part 21 is switched on and a cam 27 opens a valve 29 to start the water supply. And a turbine 11 begins to rotate and an electrical signal of a sensor is inputted into the electronic control part 21. The electronic control part 21 drives a motor 23 according to the electric signal, that is to the amount of water supply, to recover the cam 27 and the dial 5 gradually. When the dial 5 is completely recovered, the cam 27 closes the valve 29 resulting in finishing of the water supply. Thus, the dial returns continuously according to the amount of water supply, so that the amount of water supply can be visually confirmed by the position of the dial during water supply.

Title: Controller for synchronous rotary phase modifier
Inventor: WADA YOSHIHARU
IPC: H02J3/18
Filed: 1992-07-21
Abstract: PURPOSE:To prevent the operation of a limiter and to effectively display a constant voltage control function by changing the voltage of an output terminal in accordance with the deviation of the float set value being the reference operation value. CONSTITUTION:A controller 5 detects the current and the voltage of a system by the detectors 10 and 13 by use of the detection signals of a current transformer 12 and a transformer 6 connected to a system. Then the controller 5 calculates the wattless power Q generated by a rotary phase modifier RC and compares this value with the set value Qref of the wattless power Q to obtain the deviation DELTAQ. The deviation DELTAQ given from a subtractor 15 is integrated by an integrator 16, and the integrated value Vf being the integration output is subtracted from a target voltage setter 11. Then the target voltage value is changed based on the deviation of the wattless power generated by the RC. Thus it is possible to cope with the up-down change of a stable point and to control to avoid the operation of a limiter.
