Title: Biological denitrification of waste water
Inventor: SUZUKI TAKAYUKI
IPC: C02F3/08
Filed: 1984-05-18
Abstract: PURPOSE:To simply and economically hold the amount of denitrification bacteria as the whole of a waste water treatment process to a predetermined one, by reducing denitrification bacteria propagated upon the digestion of BOD substances in a denitrification process by internal respiration in the other denitrification process. CONSTITUTION:Waste water 1 containing NH3 and BOD is introduced into a denitrification process A along with recycled nitrated water 2 to perform the denitrification of NOx in the recycled water 2 by the BOD component of the waste water 1 and the treated solution is introduced into a nitration process under an aerobic condition not only to nitrate NH3 in the solution but also to perform the oxidative decomposition of the remaining BOD while a part of the nitrated solution is recycled to the denitrification process. The remainder is denitrified by the internal respiration of denitrification bacteria in a denitrification process and taken out as treated water 4. At this time, denitrification bacteria are propagated upon the digestion of BOD substances in the denitrification process A and denitrification bacteria adhered consuming the org. substance in denitrification bacteria cells are gradually reduced by the internal respiration in the denitrification process B. Therefore, if the amounts of denitrification bacteria in the processes A, B are same, about 80-90% of NOx-N formed in the nitration process 3 is recycled to the process A and the remainder may be removed in the process B.

Abstract: PURPOSE:To prevent the shift of a formed film cylinder, film detachment and film cutting, by detecting a discrimination mark such as a seamed part or a terminal end part having difference in light perviousness by photoelectric tube detection apparatuses different in sensitivity arranged in a film running process. CONSTITUTION:When a film 2a runs to the position of photoelectric tube detection apparatuses from a wound roll 1a while the adhesive place of the tape 9a or 9b of the film 2a is withdrawn, a detection signal is outputted from the high sensitivity photoelectric tube detection apparatus 3a in the case of the tape 9a high in light perviousness but the low sensitivity photoelectric tube detection apparatus 3b can not detect the tape 9a and the detection signal is not issued from said apparatus 3b. In the tape 9b low in light perviousness, detection signals are issued from both photoelectric tube detection apparatuses 3a, 3b. Therefore, when one of the tapes 9a, 9b is set to the discrimination mark of a seamed part while the other is set to that of a terminal end part, the seamed part and the terminal end part can be certainly and separately detected.

IPC: G01N29/24
Filed: 1981-06-30
Abstract: PURPOSE:To reduce a minor lobe to improve a directional pattern, by changing the distribution of the magnetic field density between the center and the peripheral part. CONSTITUTION:An iron core 6 around which a magnetic field generating coil 2 is wound consists of the mixture of narrow ferromagnetic wire rods W and nonmagnetic wire rods W', and the density of ferromagnetic wire rods is high in the center and is low in the peripheral part. When a current (i) is flowed to a coil 4 to flow a DC to the coil 2, a magnetic field B which is strong in the center and is weak in the peripheral part is generated near the surface of a material 5 to be examined. The density of the eddy current which is generated by flowing the current (i) to the eddy current generating coil 4 wound spirally at regular intervals is uniform. consequently, a force f generated on the surface of the material 5 to be examined is larger in an inside FI of the iron core 6 than in an outside Fphi, and a minor lobe becomes smaller than conventional lobes.

Title: Gathering fetch processing system
Inventor: MOGI KEIJI
IPC: G06F12/00
Filed: 1986-05-06
Abstract: PURPOSE:To decrease the total time needed for the retrieval of a data base by transferring the data on plural records to a user program just with a single cell when the data base is retrieved out of the user program. CONSTITUTION:A data base management system DBMS is controlled and performs the analysis of the call parameter via a cell analyzing part 3. Thus a data base access processing part 4 is called out in a fetch call mode. The part 4 retrieves records and stores the data needed for a user program 6 in a transfer buffer 11 via a data base 10 by an amount equivalent to the number of designated records. Then a data transfer processing part 2 transfers data to a data receiving area 13 at the user program side via a common service area 12. In such a way, the data equivalent to plural records are transferred to the program 6 just with a single call. As a result, the DBMS calling frequency of the program 6 is decreased and therefore the total time needed for the retrieval of the data base 10 is shortened.

Abstract: PROBLEM TO BE SOLVED: To stabilize stepping motor drive which achieves sewing action, even if the pulse period of encoder signals outputted from an encoder signal generator fluctuates because of fluctuation in load working on the main spindle of a sewing machine. SOLUTION: Even if the rotation of the main spindle of a sewing machine becomes uneven because of fluctuation in load working on the main spindle of the sewing machine in each sewing cycle during the execution of sewing and the pulse period of encoder signals outputted from an encoder signal generator fluctuates, the next one corrected encoder signal is generated from a plurality of the previous newest encoder signals every moment by corrected encoder signal generation control, so that abrupt changes in pulse period of the encoder signals are smoothened in the manner of annealing and ideal corrected encoder signals can be generated every moment.  By driving a shuttle driving motor in synchronization with the averaged corrected encoder signals, the shuttle driving motor can be driven at a stable rotating speed, so that all of rotating shuttles can be rotated smoothly and seam formation can be stabilized.

Title: Radio wave propagating line delay measuring device
IPC: H04B17/364
Filed: 1992-03-30
Abstract: PURPOSE:To measure a delay profile with high accuracy by converting transmitting coded signals to plural narrow band signals, transmitting them, converting these signals to the signal spectrum of the source coded data signals on the reception side and afterwards correlating it. CONSTITUTION:A coded signal generating circuit 1 generates a code pattern synchronously with a synchronizing signal from a frame synchronizing signal generating circuit 6. This pattern is divided into N pieces of band signals by an N stagger narrow band pass filter 2 and afterwards, those signals are converted to N pieces of fundamental signals at a fundamental frequency converting circuit 3 by shifting those central frequencies to one prescribed common frequency. These signals are successively switched according to the synchronizing signal of the signal generating circuit 6 and transmitted after modulating carriers by an RF band modulation circuit 5. On the reception side, those signals are demodulated after being converted to an intermediate frequency band and correlated each other with the transmission side pattern at a mutual correlation circuit not shown in the figure while removing noise. Thus, the delay profile of a radio wave propagating line is decided.

Abstract: PURPOSE:To prevent pressure feed from being set in a hard state, and reduce the burden of an operator by driving a feed water pump to feed water into a hopper, when the driving hydraulic pressure of a hydraulic pressure detector exceeds the set pressure of a hydraulic pressure setting device. CONSTITUTION:When the moisture content rate of earth and sludge in a hopper 2 is extremely lowered or the moisture content rate of sand is suddenly increased, then pressure feed resistance in a pressure feed pipe is made higher, and pressure feeder driving hydraulic pressure is made higher, and the output signal level of a hydraulic pressure detector 9 is made higher. When it exceeds the set current value of a hydraulic pressure setting device 11, then operation signal is generated from a controller 10, and a feed water pump 5 starts operation, and water is fed into the hopper 2. Accordingly, the fluidity of earth and sludge in the hopper 2 is made higher, and pressure feed resistance in the pressure feed pipe is lowered, and the pressure feeder driving hydraulic pressure is lowered. Besides, when the output signal level of the hydraulic pressure detector 9 is made tower than the set value of the hydraulic pressure setting device 11, then the operation signal of the controller 10 is stopped, and the feed water pump 5 is stopped.
