Abstract: PURPOSE: To cool the fluorescent face thus to increase the output light, by inclining the fluorescent face and projecting screen of cathode ray tube where the fluorescent face is inclined against the tube axis against the optical axis of projecting lens.  
     CONSTITUTION: The electron beam 16 from the electron beam 16 in the glass valve 11 is scanned by means of deflecting coil 15 and irradiates the fluor scenteface 12 inclined against the electron beam 16. The fluorescent face 12 is provided on one face of ground metal 17. The picture image is taken out from the window 18 made in the side wall of cathode ray tube and projected by means of projecting lenz 19 on the screen 21.

IPC: G21C19/46
Filed: 1997-04-04
Abstract: 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).

Abstract: PURPOSE: To obtain an excellent calorimeter by controlling the stepping speed of a motor by calculating the compensation variation of a control frequency by means of a computer.  
     CONSTITUTION: Coal is fed by means of a main coal feeder 1. The coal continuously flows to a coal pulverizer 3 which pulverizes the coal.
