Title: Retreatment of used nuclear fuel
Inventor: YOKOI HIROTO
IPC: C25C3/34
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To enable the retreatment of used nuclear fuel even in the atm. air by dissolving the used fuel and using a mixture composed of a fluoride salt and chloride salt as a fused salt to recover uranium and plutonium by the electrolysis thereof. SOLUTION: The oxide fuel 2, liquid crystal metal cadmium 3 and the fused salt 4 contg. the fluoride salt and the chloride salt are charged into an electrolytic cell 1. At this time, the chloride of an eutectic compsn. of lithium chloride and potassium chloride is low in m.p. and is preferably used. A cathode 5 is, thereafter, immersed into the fused salt 4 and an anode 6 into the metal cadmium 3 and an electrolysis is effected by a DC power source 7. The metal ions of the uranium and plutonium in the fused salt are then reduced at the cathode and precipitate 8 is produced. At this time, only the uranium and plutonium which are relatively low in the tendency to form chloride is selectively precipitated by regulating the cathode potential.

IPC: G03G15/06
Filed: 1985-04-30
Abstract: PURPOSE:To prevent a toner image from being disordered, colors from mixing, and toner from scattering by providing an electrophotographic device with plural developing devices, releasing a developing device which is not used for image formation from being driven, and also removing toner from the sleeve of the developing device before an original image is exposed.

An electrostatic area is formed on a photosensitive drum 1 during the preliminary rotation and toner which sticks on and nearby a part of a sleeve 5a coming closest to the photosensitive drum 1 is attracted to the electrostatic area of the photosensitive drum 1 and sticks thereupon. The sleeve 5a does not rotate and the position of the sleeve 5a facing the photosensitive drum 1 is unchanged, so that no toner sticks on the photosensitive drum 8 when a copying process is entered. Consequently, a monochromatic sharp visual image is formed.
