IPC: H02N2/00
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and simplify a circuit by eliminating an external clock source, that becomes the reference frequency of the speed control of an ultrasonic motor, and to perform the stale speed control of the ultrasonic motor. SOLUTION: A self-exciting oscillation circuit is used for the drive circuit of an ultrasonic motor, and a self-exciting oscillation signal being generated from an oscillation circuit is used as the reference frequency of the speed control of the ultrasonic motor. A comparison command means compares the frequency of a reference signal, based on an oscillation signal being generated by the oscillation circuit with the rotary information of a traveling body being driven by the oscillation signal, and outputs an output signal to a start/stop signal generation circuit according to the result. The start/stop signal generating circuit starts or stops the oscillation circuit, so that the rotary information becomes equal to the frequency of the reference signal, based on the oscillation signal according to the output signal of the comparison command means, thus keeping the speed constant.

Abstract: PURPOSE:To enable a remained water to be detected even if its volume is low and to enable an efficient hot water feeding operation to be carried out by a method wherein a releasing bath water sensing circuit is formed at the bottom part of a bath tub and a bath water sensing means is arranged in the sensing circuit. CONSTITUTION:Since a passage 21 is communicated and connected to the bottom wall of a bath tub 2, a remain water in the bath tub 2 if a little bit of water remains there is sucked by a circulation pump P and circulated in an additional firing circuit 3. A water flow switch 31 is turned ON and the presence of remained water can be judged. In the event that the remained water is present, the circulation pump P is stopped, a changing-over valve 25 is changed over to cause the additional firing circuit 3 to be shielded. In addition, a hot water feeding valve 11 is opened to supply hot water to the hot water feeding valve 11, a passage 22 and the bath tub 2 so as to start a hot water feeding operation. The hot water feeding operation is promoted while a water level in the bath tub 2 is being checked by a water level meter 34 arranged in the passage 21. When the water level in the bath tub 2 reaches a target water level and a hot water feeding completion signal is outputted from the water level meter 34, the hot water feeding level 11 is closed with a signal and then the hot water feeding operation is stopped.
