Title: Power supplying method using converter
Inventor: AOKI YUKIO
IPC: H02M7/493
Filed: 1981-04-23
Abstract: PURPOSE:To limit the cross current of converters with the reactor of a filter at the time of parallel operation by maintaining the voltage of the filter at the previous stage constant with the converters and maintaining the voltage of the filter at the rear stage at a voltage determined by another AC power source. CONSTITUTION:A voltage detecting line 13, a current detecting line 14, and a commercial power source voltage detecting line 10 are connected to a control circuit 12, which applies a pulse which is controlled in its pulse width so that an output voltge becomes constant to the bases of switching elements S1-S4. When there is a difference between a voltage supplied to a load 2 from a commercial power source 1 and the output voltage of a converter 4 at the time of parallel operation, the voltage of the difference is applied to the reactor L of the filter 5, and a cross current determined by the voltage value of the difference from the impedance of the reactor L flows. Since the line voltage is detected by the previous stage of the filter 5, the constant voltage of the converter 4 can be controlled substantially irrespective of the commercial power source voltage, thereby limiting the increase in the cross current.

Title: Resistor for wiper switch
Inventor: HIRAI KOJI
IPC: H01C10/32
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a resistor for wiper switch from which it can be surely judged whether or not the wiping speed of a wiper is in a car speed corresponding mode. SOLUTION: As far as sliding contacts 31a and 31b bridge the space between silver thin film sections 24a and 24b, the resistance value of a resistance circuit is maintained at a slightly increased value. Whether or not the wiping speed of a wiper is in a car speed corresponding mode in which is wiping speed changes in accordance with the running speed of a vehicle is judged by detecting the resistance value of the resistance circuit when the constants 31a and 31b bridge the space between the thin film sections 24a and 24b. Since the resistance value of the resistance circuit is fixed at the slightly increased value even when the rotational angle of a control knob 5 varies more or less, whether or not the wiping speed is in the car speed corresponding mode can be judged surely.

IPC: H02M7/12
Filed: 1989-03-15
Abstract: PURPOSE:To prevent an input rectifying diode of the side having no open-phase state from damaging by providing an open-phase detector in a DC power source which inputs 3-phase AC. CONSTITUTION:If one of input three phases becomes open, an output of a rectifying diode side connected to an open-phase line of an open-phase detector 8 cannot maintain the output of a photocoupler 19 or 20 to be connected at 'L'. Accordingly, an AND circuit 23 is judged to be abnormal, a signal of abnormality is sent to a PWM controller 7 to stop the operation of an inverter 4. If the inverter is stopped, a current flowing to a rectifying diode in which no open-phase state exists becomes a very small value, thereby preventing it from damaging.

IPC: C02F1/50
Filed: 1994-03-31
Abstract: PURPOSE:To realize active water production which is not affected by makeup water even if the makeup water is added to a water storage tank by operating an ozone generating means for the time corresponding to the volume of the water supplied to the water storage tank by a control means. CONSTITUTION:The active water is produced by judging whether the water exists in the water storage tank 5 or not, judging whether the tank is full or not when the existing of water is judged, then cooling the water and mixing ozone with the water so as to dissolve more oxygen than usual into the water when the tank is full of the water. Whether the temp. is adequate or not is judged and control to cool the water is executed when the temp. is inadequate. The extended water discharge time is counted after the full water at the time of discharging the water. On the other hand, whether or not the water discharging time and the extended time of the open time of a water discharge solenoid valve 53 are zero is judged at the time of the full water when the water is not discharged. The case the water discharging time is not zero is indicative of the makeup water and, therefore, the time for producing the active water is regulated according to the water feed rate by the controller 68 and the ozone is generated for the prescribed period of time from an ozone generator 39. Thereafter, the water feed is stopped to stabilize the dissolved oxygen.

Title: Heat exchanging method
Inventor: MORI ISAKATA
IPC: F28C3/04
Filed: 1980-05-13
Abstract: PURPOSE: To improve the heat exchanging efficiency, the safety and the reliability of a heat exchanging method by contacting and circulating a temperature controlled liquid and another inert temperature controlling liquid having larger specific weight than that of the controlled liquid directly in a tank when controlling the temperature of an etchant or the like.  
     CONSTITUTION: Inert temperature controlling liquid 30 having larger specific weight than that of a temperature controlled liquid 11 is so filled in a tank 20 that pipes 21, 22 are submerged, and is circulated through a pump 5 and a heat exchanger 7. The liquid 11 is filled in a predetermounted amount on the liquid 30. Since the liquid 11 has smaller specific weight, it is isolated via a boundary surface B on the liquid 30. Since the liquid 30 flows in a direction of arrows, the liquid 11 contacting at the boundary surface B will also circulate and agitate in a direction of arrows and will heat exchange through the boundary surface B with the liquid 30. Thus, it can improve the heat exchanging efficiency, the safety and the reliability.
