Title: Reduction method for generation of radioactive waste from nuclear fuel reprocessing process
Inventor: IWAMOTO FUMIO
IPC: G21F9/06
Filed: 1990-08-31
Abstract: PURPOSE:To reduce the generation of wastes by electrolyzing liquid waste of nitric acid, reacting generated NOx with NH3 using catalysts to reduce it to N2 and H2O, and discharging them. CONSTITUTION:Liquid waste of nitric acid containing radioactive substances generated from the nuclear fuel reprocessing process is led to an electrolytic cell to be electrolyzed to generate NOx, HNO3 is decomposed with the radioactive substances remained on the liquid side, and the generated NOx is reacted with NH3 using catalysts to be reduced to N2 and H2O and to be discharged. Remaining electrolyte of reduced HNO3 concentration is concentrated by distillation, a part of the concentrated electrolyte is circulated to the electrolytic cell to be electrolyzed together with the liquid waste of nitric acid, the remaining part of the concentrated electrolyte is sent to the radioactive waste processing process to be processed, and distillated water is necessarily neutralized to be discharged. Thus, since most of the waste can be converted into harmless N2 gas to be discharged into atmosphere, and dilute nitric acid generated by electrolysis can be distillated and concentrated to be electrolytically processed again, the quantity of liquid waste sent to the liquid waste processing process can be reduced below a fraction of the original liquid waste.

IPC: B04C3/00
Filed: 1985-10-16
Abstract: PURPOSE:To obtain a swirl vane of a gas/water separator having high separation efficiency by forming an oblique wall inclining obliquely downward to an external peripheral wall of a cylindrical partition wall member and extending the oblique wall gradually from an upper end toward a lower end of the oblique wall to form stepwise spiral wall at the lower end of the oblique wall to an end wall directing to radial direction. CONSTITUTION:Five swirl vanes 10 are formed in an annular space and consist of vertical walls 11 formed to protrude from an upper end of an inside cylinder 4 of a partition wall member 4 diametrally to the upper end of an outside cylinder, oblique walls 12 formed obliquely from the lower end of the vertical wall 11 obliquely downward, and spiral walls 13 formed on the upper surface of the oblique wall 12 spirally toward the periphery of the outside cylinder. The end of the spiral wall 13 connects stepwise to the end wall in the diametral direction. By this constitution, water drops are collected positively on the edge line bonding the spiral wall to the end wall. Since the water drops are blown off from the edge line part to the inside wall of outside casing, extremely high gas/water separation efficiency is attained.

IPC: G06F9/46
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To effectively utilize the computer resources without using a backup computer by processing the transactions of both computers with each other and reflecting and holding these processing results of transactions. SOLUTION: A terminal 10 sends an execution request and a transaction processing request telegraphic message (a) including the destination information on computers to a system information management computer 100. A backup constitution management part 110 of the computer 100 manages the operation states of computers 200A, 200B and 200C and also the information on the backup destination computers against the occurrence of the failure of every computer. If a computer is unable to operate, the message (a) is sent to the relevant backup destination computer. When the faulty computer is recovered and its transaction processing is currently executed, the message (a) to be executed by the backup computer is distributed for the execution of the relevant transaction. Thus, a backup destination computer can process plural transactions among plural computers.

Inventor: TODA TAKESHI
IPC: G11B7/12
Filed: 1988-09-19
Abstract: PURPOSE:To execute one axis of a light axis and to miniaturize a device by detecting a focus error signal by an astigmatism method, detecting an error signal for tracking control by a push pull method, forming always a light spot on a recording medium and controlling the light spot in the direction to record and reproduce the information.

Since a focus error and a tracking error signal are detected by using the reflecting light reflected from the recording medium 5, an effective light flux diameter 7 of an image forming lens 4 is larger than the effective light flux diameter 6 of the converging lens 2, and the number of actual effective apertures of the image forming lens 4 determined by the effective light flux diameter 6 of the converging lens 2 becomes smaller than the number of aperture determined by the effective light flux diameter 7 of the image forming lens 4. Thus, one axis of the light axis and the miniaturization of a device can be executed.
