Title: Denitrifying method for water treatment
Inventor: KUNIMORI ICHIROU
IPC: C02F3/34
Filed: 1980-08-22
Abstract: PURPOSE: To economically perform sewage stirring and malodorous gas treatment in a storage tank by supplying the gas produced in activated sludge treatment for night-soil-contg. sewage into the night-soil-contg. sewage in the storage tank for the purpose of stirring said sewage.  
     CONSTITUTION: The crude night soil from a storage tank 1 is supplied into an aerobic digesting tank 3, where gas contg. oxygen such as air is blown into the crude night soil through a gas supply line 4 and the crude night soil is circulatively flowed by a pump flow passage 5 so that BOD is lowered by the effect of aerobic activated sludge. The gaseous N 2  produced in the nitrifying treatment is removed. The malodorous gas produced in the tank 3 is supplied through a pipeline 7a into the crude night soil in the tank 1 for the purpose of stirring the same and the malodorous gas produced in the tank 1 is supplied through a pipeline 7b into the tank 3 for the purpose of stirring the water to be treated in said tank. Thereby, the ammonia and the like in the malodorous gas are absorbed in the crude night soil and the water to be treated and H 2 S is decomposed by desulfurizing germs.

Title: Plane indication device and storing method therefor
Inventor: MINOHARA KIYOMI
IPC: G01S7/04
Filed: 1979-09-11
Abstract: PURPOSE:To enable indication on CRT and the like without any trouble in actual employment even when a memory of small capacity is used by a method wherein the amplitude compression is performed only for signals required for indication after they are passed through a clutter level, by the use of a nonlinear amplifier. CONSTITUTION:A pulsation signal transduced from a reflection signal by a detector 4 is given to a clutter-level adjuster 6 and only a required constituent of signal exceeding a clutter level set beforehand is added to a nonlinear amplifier 7. In the nonlinear amplifier 7, the signal is amplified in such a manner that the degree of amplification of a signal of large amplitude is restricted, and, since a signal of low level is cut beforehand, a signal of middle level is to be stored in a memory 9  through an A/D transducer 8. Thus, the capacity of the memory 9 can be made small. In addition, if a nonlinear D/A transducer formed through unification of a D/A transducer 10 and a nonlinear amplifier 11 is employed, correction of linearity of an indicator such as CRT and processing for an image thereby indicated are also turned to be possible.

Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To reduce through current flowing between power sources during a sampling operation by setting the respective drain terminals of a PMOS transistor and a NMOS transistor, which are adjacent to a power terminal-side, to be the output terminals of a holding signal and providing switch element couples which are adjacent to an output terminal-side and which are complementarily on/off-controlled. SOLUTION: Switch elements 61-64 and 71-74 are connected to control input terminals 41 and 51 inputting a clock signal ϕ and a clock signal *ϕ. Thus, the switch elements 61-64 and 71-74 complementarily operate. In a transient process where the NMOS transistor 82 and the PMOS transistor 83 shift to ON states and the PMOS transistor 81 and the NMOS transistor 84 in OFF states, the switch elements 71-74 are already and completely in the OFF state. Thus, through current between a high potential power terminal 91 and a low potential power terminal 92 is eliminated and wasteful power consumption can be prevented.
