Title: Treating apparatus for waste water
Inventor: KIJIMA JIRO
IPC: C02F9/00
Filed: 1988-07-21
Abstract: PURPOSE:To reduce running cost for the treatment of waste water by constituting a treating apparatus of a wet oxidation tower, an insolubilizing tank for insolubilizing P by adding an insolubilizing agent for P to the treated water of the wet oxidation tower, and a membrane separator for separating the reaction liquid from the insolubilizing tank for P through a precision filtration membrane or ultrafiltration membrane. CONSTITUTION:Waste water contg. materials to be oxidized and P from a feed liquid feeding line a is fed to a wet oxidation tower 1, where it is heated and pressurized to oxidize the material to be oxidized in the waste water, and the materials to be oxidized are decomposed to gaseous CO2, N2, and water. The gas/liquid mixture is transported to a gas/liquid separation tower 3, and treated water decomposed by the oxidation in the tower 3 is transported to an insolubilizing tank 10 for P, where it is mixed and stirred with slaked lime and a pH adjusting agent in a mixing and stirring zone 12. Thus, the P in the treated water is insolubilized. The treated water contg. the insolubilized P overflows a top of a separating wall 11 and is introduced into a pump pit 13, then fed to a membrane separation device 20 hosing an ultrafiltration membrane therein through a line 19. Permeated water of the membrane separation device is discharge out of the system. Thus, the frequency of washing in the membrane separation device 20 is reduced.

Title: Gas laser device
Inventor: OGURA YASUHIRO
IPC: H01S3/097
Filed: 1989-07-17
Abstract: PURPOSE:To rapidly vary laser output according to a processing purpose while using power supply of constant output and to miniaturize the size of the device, by using power supply of constant output as the power supply of a current to be applied to a discharge part while turning ON-OFF the output within a relaxation time. CONSTITUTION:A discharge part 2 for pumping laser gas and load 3 are connected to an AC power supply 1 for outputting a constant current of constant frequency through a switching circuit 4. And, the switching circuit 4 performs switching of the discharge part 2 and load 3 at a speed, for instance, more than ten times the laser relaxation time after laser gas is pumped by discharge. Thereby, keeping an output current from AC power supply constant and only by switching at quicker speed than the laser relaxation time by the switching device 4, laser output can be changed in multistages. Further, since the ON-OFF switching speed by the switching device 4 is a remarkably higher speed than that of changing the output of an AC power supply itself, laser output can be changed more rapidly than conventional ones.

IPC: C21B7/24
Filed: 1982-10-19
Abstract: PURPOSE:To instantaneously detect the generation of a leak accident with respect to the time and the place thereof, by detecting the leak place of a cooling medium from the relation of the speed difference in both sound receiving times of two A.E wave measuring apparatuses each receiving a sound caused by the leak of the cooling medium flowing through a shaft furnace cooling equipment.

The distance between the position where the sensor 1 is attached and a central small orifice 15o is made equal to the distance between the position where the sensor 1' is attached and the small orifice 15. That is, the small orifice 15o is present at the center between the positions where the sensors 1, 1' are attached. Preamplifiers 1a, 1a' are usually mounted in the sensors 1, 1' while main amplifiers 2a, 2b, filters 2b, 2b', average value detectors 2c, 2c' and signal discriminators 2d, 2d' are mounted in the A.E main bodies 2, 2'. Now when a stop cock 16p is loosen and the small orifice 15p near to the sensor 1 amoung small orifices 15o, 15p, 15g each held under a closed state is opened, a time (t) is necessary before the leak sound generated in the small orifice 15p reaches the sensor 1 while a time (t') is necessary before reaches the sensor 1'. It is understood that speed difference is generated in the leak sound receiving times of the A.E main bodies 2, 2' due to the distance from a leak place.

CONSTITUTION:Compressed air from an air source 50 is sent to a hollow part of an oil tank 64 through a secondary air pipe 62. A lubricating oil in the tank 64 is compressed by the air and supplied to a nozzle head 60. The inside of the oil tank 64 is compressed to, e.g., 0.2atg, and the lubricating oil is supplied to an inner tube 86 through an oil feeding pipe 68. An oil chamber 100 is always filled up with the new lubricating oil. Meanwhile, the compressed air from the air source 50 is supplied to a hollow part 102 of an outer tube 80 through an air feeding pipe 52. When voltage pulses, which are generated in a pulse generator 72, are applied to an electric distorting element 88, the electric distorting element 88 and a metal plate 90 are deformed in the direction of the plate thickness (right and left directions). As a result, the volume of the lubricating oil in the oil chamber 100 is changed (decreased), pulse shaped pressure change is generated in the oil chamber 100, and the lubricating oil is jetted out of an orifice 92 as oil droplets 104.

Filed: 1982-10-21
Abstract: PURPOSE:To prevent jumping up of a tape and to transfer a wide and thin tape easily, by applying a prescribed tension to a belt supporting the tape in transferring the tape from a pay-off reel to a tape winding reel. CONSTITUTION:A movable idler 20 is shifted left as shown in Figure and the belt idler 20 is moved and supported with a spring 25 applying a prescribed tension to the belt 8.

Title: Fuse break detector
Inventor: UMEDA KAZUNORI
IPC: H01H85/30
Filed: 1990-07-13
Abstract: PURPOSE:To detect the breaking of a fuse accurately and easily by using a low-cost circuit device by providing a means for outputting a signal to inform the fuse breaking from a photo-coupler. CONSTITUTION:A photocoupler 2 is provided in parallel with a fuse 1, and when current is run in a load 7 from a power source 8 through the fuse 1 and a switch 6, the emission diode of the photocoupler 2 is in a short-circuited state by a diode 4, and no current is run thereby. When the fuse 1 is broken, the current to be run in the diode 4 is cut, and current is run in the emission diode of the photocoupler 2, and the emission diode is lighted, which is detected by a photo-transistor as the breaking of the fuse. The breaking of the fuse can thus be detected easily and accurately, while the detector can be assembled out of low-cost circuit devices commercially available, and manufacturing cost is thus reduced.

Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the imbalance in three-phase relations which is caused by the variation of devices used in the current detection circuits of respective phases when a PWM type 3-phase inverter is provided and motor currents of at least two phases are detected for feedback control and realize the securer feedback control of motor currents. SOLUTION: If motor currents are so controlled as to have currents which have amplitudes equal to each other and polarities opposite to each other applied to two phases and have no current applied to remaining one phase, for instance, a current flowing out from the U-phase is totally made to flow into the V-phase and no current is applied to the W-phase. In this state, the current values of the U-phase and the V-phase are detected and outputted by current detection circuits 6a and 6b from the potential drops in the current detction resistors 2a and 2b of the U-phase and the V-phase. After the average values 11 and 12 of the respective phase currents are obtained by average value calculation units 10a and 10b, a gain ratio calculation unit 11 calculates a gain ratio K=I1/(-I2) by using the respective average values.  A predetrermined feedback gain G is employed as it is as the feedback gain G1 of the U-phase and G ×K is set as the feedback gain G2 of the V-phase.
