摘要： PROBLEM TO BE SOLVED: To provide a spatial drawing processing method capable of easily adopting a detail degree model, which is suitable when models are switched in LOD management of CAD and CG. SOLUTION: A space to be drawn is determined (S20). Information on the size of a unit solid such as an object included in the space is obtained (S21). The size distribution, therefore, unit solids are grouped and a model having a large detail degree is adopted even if a viewpoint distance becomes larger for a larger unit solid. A small unit solid is speedily switched to a model having a small detail degree as the viewpoint distance increases (S22).

摘要： PROBLEM TO BE SOLVED: To enables electrode exchange possible without destroying welding atmosphere at TIG welding, and the like. SOLUTION: The electrode exchange device comprises an electrode feeding mechanism 1, and electrode storage mechanism 2 and an electrode chucking mechanism 3 and, an electrode 17 is taken into the electrode storage hole 18 of a rotor 13 by cutting off the air by opening/closing the sealing valves 16 and 17. Then, the electrode 17 is dropped into the electrode hole 34 of the chucking sleeve 26 by rotating the rotor 13 intermittently, and furthermore, pushing the chucking sleeve 26 down by activating the air pressure on to the piston 28, so that a collet 25, which is equipped at the tip end of the sleeve 26, is pressed to the tapered face of the current carrying tip 24 to hold the electrode 17. Since the feeding, holding and discharging of the electrode can be made in an airtight condition, the electrode can be exchanged without destroying a welding atmosphere in a welding chamber.

摘要： PROBLEM TO BE SOLVED: To simplify the recovery step of transuraunium element and reduce waste solvent and wastes. SOLUTION: A spent nuclear fuel is dissolved in a nitrate acid (S100), the dissolved liquid is subject to electrolitic oxidation, and U, Np, Pu, and Am are oxidized at hexa valence by using Ce as an oxidizing catalyst, and further they are cooled to crystallize a hexavalent nitrate salt and separate it from a mother liquor (S104). The mother liquor is heated and condensed (S114). The separated mixed deposit is dissolved in a nitrate once (S106) and only an uranyl nitrate is deposited by cooling it (S108), and then it is separated from a mixing liquid of U, Np, Pu, and Am (S110). The uranyl nitrate is dissolved in a nitrate acid (S112). The nitrate solution is added with the heated and condensed mother liquor to prepare a mixing solution. The mixing solution is electrolytically oxidixed so as to oxidize the remaining U, Np, Pu, and Am at hexa valence and cool them, thereby precipitate the remaining U, Np, Pu, and Am together thanks to uranyl nitrate and separating them from high-level radiation waste.

摘要： PROBLEM TO BE SOLVED: To provide a method for facilitating the treatment of a spillage heavy oil or crude oil in the form of a viscous solid containing a treatment inhibiting substance such as seawater. SOLUTION: Titanium oxide particles in at least a ratio of 0.2 to 1 based on spillage heavy oil expressed in terms of weight ratio are added and mixed with the spillage heavy oil recovered in a metallic barrel, etc., and the heavy oil is specifically adsorbed from the spillage oil, containing seawater, etc., and converted into the form of a viscous solid on an adsorbent (S1). Water is then added to the metallic barrel to suspend the resultant mixture in water (S2). The formed suspension is filtered through a filter of a coarse mesh to remove treatment inhibiting substances of a larger size than that of the adsorbent containing the heavy oil sticking thereto, e.g. seaweed, sand or stone (S3). The resultant filtrate is recovered (S4). The recovered filtrate is then passed through a high-performance filter (a fine mesh so as to enable the recovery of the adsorbent) to recover the adsorbent containing the heavy oil sticking thereto. Thereby, the seawater, etc., together with the water for suspending, are removed (S5).

摘要： PROBLEM TO BE SOLVED: To rapidly decompose CMPO (octyl(phenyl)-N,N- diisocutylcarbamoilmethylphsophine oxide) safely, surely and by a mild condition. SOLUTION: The CMPO-containing matter is emulsified in an electrolyte containing an oxidation accelerating agent (silver ion) by an emulsifying machine of an emulsifying tank 6, and the electrolyte is fed to an anode chamber, and an electrolytic oxidation reaction is executed by energizing. An electrolysis is accelerated since a surface area of the CMPO containing with the electrolyte is enlarged by emulsifying the CMPO-containing matter. Since a sufficient CMPO decomposition is not attained by passing only once the electrolyte through an electrolytic cell, a batch type oxidizing method is adopted, and the anode liq. is circulated between the anode chamber, a thermostatic bath 7a and the emulsifying tank 6 by using a circulating pump 3a, and the electrolysis is continued in a state in which the CMPO-containing matter is always emulsified in the electrolyte. The cathode liq. is circuilaed between a cathode chamber and the thermostatic bath 7b by using the circulating pump 3b. And in the anode 4 and the cathode 5 is the electrical cell 1, a supplied current is controlled by a rectifier 8.

摘要： PROBLEM TO BE SOLVED: To provide a melt extractor which has excellent reliability and controllability, which is free not only from an electrical short of a metal furnace body and a metal flow-down nozzle but also from the noise interference between a high-frequency heating system for heating the furnace body and that for heating the flow-down nozzle when the flow-down nozzle of a high-frequency heating method is used as a melt extractor in a cold crucible induction melting furnace. SOLUTION: A flow-down nozzle 14 extending downward from the bottom in a cold crucible induction melting furnace 10 of a water cooling type is installed in the furnace 10 disposed in a high-frequency coil 11 for heating a furnace body so as to be electrically insulated from the furnace body. A high-frequency coil 15 for heating the flow-down nozzle 14 is disposed around it, and an electric circuit 17 to remove high-frequency noises from the high-frequency coil 11 for heating the furnace body is installed in the high-frequency coil 15 for heating the nozzle 14.

摘要： PROBLEM TO BE SOLVED: To reduce wobbling noises attributed to chattering and vibration of an eddy current flaw detection sensor unit by burying O-ring shaped rubber fins into grooves provided on the outer circumference of a casing of the eddy current flaw detection sensor unit. SOLUTION: Detection coils 7 concurrently which serves for the generation of a magnetic field and the detection of an eddy current is wound on a groove formed in the circumferential direction of a cylindrical eddy current flaw detection sensor unit and the two coils are wound in directions opposite to each other to be connected to a bridge circuit within the eddy current flaw detection sensor unit. Rubber fins 6 are built in before and after a casing 5 of the sensor unit. The rubber fins 6 are made like an O-ring using a silicon based rubber material and securely fitted into a grove part on the outer circumference of the easing 5. When the eddy current flaw detection sensor is inserted into a specimen, the outer most circumference of the rubber fins 6 contacts the internal wall of the specimen. At this point, contact impact between the eddy current flaw detection sensor unit and the internal wall of the specimen can be eased by the rubber fins 6.
