Title: Auxiliary inverting circuit for inverter
Inventor: HOSHI TOSHIHIKO
IPC: H02M7/515
Filed: 1979-02-02
Abstract: PURPOSE: To enable omission of an inverting capacitor and a reactor for an inverter by connecting one end of a switch having self-turn-off capacity to the intermediate tap of the primary winding of an output transformer in parallel with a thyristor connected to an outside terminal.  
     CONSTITUTION: The primary winding of an output transformer 2 in which a load 3 is connected to its secondary winding is connected between thyristors 11 and 12 having no self-turn-off capacity as main controllable electric valves and the intermediate tap M of a DC power supply 1. Transistors 21, 22 and flywheel diodes 31, 32 are connected as a turn-off controllable electric valve through the winding portion 5 of the intermediate tap A and outside terminal to the intermediate tap A of the primary winding of the transformer 2 in parallel with the respective thyristors 11, 12. Since the induced voltage at the winding portion 5 is applied as a reverse bias to the thyristor 11 when the transistor 21 is conducted at its inverting time, the thyristor 11 is turned off. The transistor 22 may be conducted for short time to turn off  the thyristor 12.

Title: Method and device for treating waste water by electric discharge electrolytic heating
Inventor: OBA KAZUO
IPC: C02F1/463
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To momentarily flocculate and solidify pollution in waste water and to treat a large amount of the waste water at low cost by executing an electric discharge electrolytic heating to the waste water and flocculating the pollutant incorporated in the waste water. SOLUTION: In this electric discharge electrolytic heating device of an immersing method by which the substance S to be heated is immersed in an electrolyte L, an anode E, the substance S, a pump P, the electrolyte L and a direct-current power supply DC are provided. When a voltage between both electrodes immersed in the electrolyte L is gradually raised, a current proportional to the voltage is made to flow from zero to a prescribed value A, and bubbles of hydrogen are generated on the surface of the substance S (cathode) to be heated by electrolysis. Then, when the voltage is raised to more than the prescribed value A, a contact between the substance S and the electrolyte L becomes intermittently with a generated hydrogen and steam and a spark discharge is generated.  When the voltage is raised moreover, the whole surface of the substance S is covered with a gaseous film, and a fine arc discharge is generated through the gaseous film and the surface of the substance S is heated, and in this way, the pollutant in a waster water is flocculated and solidified.

Title: Dc/dc converter
Inventor: UEKI YOUICHI
IPC: H02M3/28
Filed: 1984-01-25
Abstract: PURPOSE:To prevent the output voltage from rising by reducing a voltage applied to a choke coil at a light load time, thereby preventing the choke current from intermittently interrupting. CONSTITUTION:If an output voltage is higher than the prescribed value, a comparator CMP2 turns OFF transistors Tr1, Tr2 and alternately turns ON and OFF FETs Q1, Q2 in accordance with the voltages generated in windings N4, N5. If the output voltage is lower than the prescribed value, the comparator CMP2 applies the voltage in response to the difference to between the bases and the emitters of transistors Tr1, Tr2, thereby operating the transistors in an analog manner. As a result, the FETs Q1, Q2 are operated in the analog manner. Since the resistance value when the FETs Q1, Q2 are ON becomes higher than that at the switching time, the voltage applied to a choke coil L decreases.

Abstract: PURPOSE:To make equal the average driving factors of respective fans and to reduce fault generating ratio of fans by controlling to allot fans in a number required for heat exchange in a predetermined procedure, among a plurality of fans attached with numbers circulated and repeated in a predetermined sequence. CONSTITUTION:An air-cooled type heat exchanger 5 comprises a main body 51 of a cooling-finned heat exchanger and cooling fins 520, 521-52n.

Further, the number of the end is continuous to the number of the top. Thus, the circulation and repetition of numbers are carried out. When the ability of the heat exchanger is varied, fans in numbers succeeding to the number of the end of fans now in operation are successively selected and started upon increasing the number of fans to be driven. Upon decreasing the number of fans to be driven, fans in numbers succeeding to the number of the top of fans now in operation are successively selected and stopped. Thus, the ability of the heat exchanger can be controlled to a desired value.

When the case 14 is placed in an area on a desk where eraser dust is scattered, the eraser dust is floated by the air current, hits against the filter 18 and adheres on it. When the motor stops, the eraser dust falls off from the filter 18 and is stored in a dust container 21. Thus, the eraser dust, etc., can be easily removed.

Filed: 1990-01-24
Abstract: PURPOSE:To suppress the fluctuation of a resonance point even if an L value is varied, and to always measure the signal with high quality by executing the control so that a tuning voltage applied in order to take tuning is varied in accordance with a respiratory motion, with respect to a fluctuation of the resonance point which follows a fluctuation of the L value caused by a shape variation of a flexible type receiving coil. CONSTITUTION:A tuning voltage generating part is contained in a sequencer 12, and its tuning voltage generating part 1 generates a prescribed voltage as usual. A respiration sensor 3 generates a waveform corresponding to a motion executed by respiration of a body 6 to be examined. An obtained respiratory waveform 5 is amplified by an amplifier 4 and added to a voltage from the tuning voltage generating part 1 by an adder 2, and applied to a receiving coil 20b. As for a relation of an applied voltage of a variable capacity element of a tuning part in the receiving coil 20b and the capacity, the higher the voltage is, the smaller the capacity becomes. As a result, when an L value becomes large by inspiration and the voltage rises, the capacity decreases, and on the contrary, in the case of exhalation, the L value becomes small, the capacity increases, and a variation of a tuning point can be suppressed, comparing with the time when the tuning voltage is constant.
