Title: Speed controller for water turbine or pump turbine
Inventor: WAKABAYASHI SEI
IPC: H02P9/04
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To improve the stability and responsivity of a water turbine (pump turbine). SOLUTION: A speed controller 100 takes as control deviation input 6 the sum of the difference between the load target value of a load adjusting device 1 (65P) and the opening of a guide vane 2 and the difference between the frequency target value (50 Hz, etc.), of a frequency adjusting device 3 and water turbine rotational speed 4 (N), performs computation through a PID operation part 7 to actuate a mechanical actuator 12, operates the opening of the guide vane 2 to control the flow rate 13 of the water turbine, and adjusts a generator load 14. In ordinary constant load operation, the load target value is equal to the opening of the guide vane, and the frequency target value is equal to the rotational speed of the water turbine. Thus, operation is performed with the opening of the guide vane kept constant.  If the load is disconnected, the load target value (65P) is immediately zeroed and the guide vane is quickly closed to suppress sudden rise of the water turbine (pump turbine). Thus the stability and responsivity of the water turbine are improved.

Title: Method and apparatus for activating water
Inventor: HIDA SHUICHI
IPC: C02F1/48
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To produce activated water of sufficient activation level always industrially by retaining to-be-treated water in a zero magnetic field in which a highly waving substance is arranged for a prescribed length of time. SOLUTION: Zero magnetic field generation sources 2, 3 are arranged on both sides of a pipe 1 to be a to-be-treated water passage, and a zero magnetic field 4 is formed by the sources 2, 3. The pipe 1 is made to pass through the zero magnetic field 4, and a high wave motion substance (e.g. bamboo charcoal) 5 is disposed in the zero magnetic field between the source 3 and the pipe 1 to constitute a water activation apparatus. The passage length of the zero magnetic field 4 of the pipe 1 is regulated so that the time required for the passage of raw water is longer than that necessary for the activation of raw water.  In the activation apparatus, when to-be-treated water is passed through the pipe 1 at a prescribed flow velocity to retain the water in the zero magnetic field for a prescribed time (e.g. 20 sec or longer), the wave motion of the substance is transferred so that the waving of the water is intensified to activate the water.

Title: Screen stopping circuit of television receiver
Inventor: HON SAMU PIYO
IPC: H04N5/44
Filed: 1990-12-14
Abstract: PURPOSE: To easily grasp a final input state by displaying a video signal after final input processing as a stop screen on the television image receiver when it is determined that no input video signal is inputted from a video camera. CONSTITUTION: When a video signal VI is not inputted, a transistor(Tr) Q1 turns off and a Tr Q2 turns on, so that a low potential is outputted from the collector. Therefore, an FF 13 of an integrator 14 is reset and a high-potential signal is outputted from an inversion output terminal Q and applied to a RAM 5 through an OR gate 15. Further, the high-potential signal from the inversion output Q is inverted into a low-potential signal, which is applied to an AND gate 17. Therefore, the low-potential signal is applied to a write terminal of the RAM 5 regardless of a write signal of a controller 4. Therefore, the RAM 5 is held in a read state regardless of signals from a read terminal and the write terminal of the controller 4, and a stop display of only a luminance signal Y and color difference signals R-Y and B-Y which are recorded last is made on the television image receiver as a video signal.

Title: Switching power supply
Inventor: NAGASAWA YASUO
IPC: H02M3/28
Filed: 1990-12-20
Abstract: PURPOSE:To achieve an ideal constant current drooping characteristic even if DC output voltage reaches close to zero point in the overcurrent region of a switching power supply. CONSTITUTION:An output voltage detecting circuit 18 divides an output voltage Vo through resistors 19, 20 and outputs a current corresponding to the output detection voltage from an operational amplifier 21. An oscillator 25 outputs pulses having frequency variable according to the output level of the operational amplifier 21 and a reset synchronizing signal is fed through transistors 27, 28 to the timing capacity terminal CT of a control IC 17 in order to synchronize the oscillation frequency of an oscillation circuit with that of the oscillator 25. Consequently, even if the conduction pulse width is fixed at a minimum value due to latching lag of a flip-flop circuit 15 in the overcurrent region, duty for a switching element 3 can be reduced by lowering the frequency of the reset synchronizing signal.
