Title: Copied image retouching solution
Inventor: KUZUWATA MASAYUKI
IPC: B41C1/10
Filed: 1983-07-22
Abstract: PURPOSE:To enable retouching of a copied image usable as an offset master and an intermediate original by using a soln. composed essentially of alkyl acetoacetate and polyol deriv. CONSTITUTION:A retouching soln. is composed essentially of alkyl acetoacetate (ACACA) and polyol deriv. As said ACACA, e.g. ethyl acetoacetate is used and it alone is low in power of dissolving a toner image, and it takes too long time to retouch the image. As the polyol deriv., e.g., diethylene glycol diethylether alone is too strong in dissolving power, and has a danger of dissolving a coating on the nonimage part, but a mixture of this and said ACACA gives a proper dissolving power for a resin, and the toner image has no danger of being finely dispersed and decomposed. It can retouch even a toner image formed on an impregnated type semitransparent paper like plain paper among various of transparent papers usable as the intermediate original of the plain paper copying machine (PPC). It is also usable for retouching a diazo image.

Title: Operating method for molten carbonate fuel cell
Inventor: NAKANISHI TSUNEO
IPC: H01M8/04
Filed: 1987-05-28
Abstract: PURPOSE:To prevent the deterioration of an anode by supplying a protection gas prepared by mixing a small quantity of hydrogen gas to inactive gas to the anode only when a cell is started or stopped except for noral operation. CONSTITUTION:When a cell is started, a valve 12 is closed and valves 13, 14 are opened to supply a protection gas prepared by mixing hydrogen gas with nitrogen gas to a fuel gas chamber 6 after heating. A small amount of oxygen in a commercial inactive gas or oxygen in the air penetrated from the outside of the cell is reduced by hydrogen in the protection gas to prevent the oxidation of an anode 2. When the temperature of the cell is increased to a specified temperature, the valves 13, 14 are closed and the valve 12 is opened and fuel gas is supplied to the gas chamber 6 to perform power generation. When the cell is stopped, valves are switched in the same way as starting, and the protection gas is supplied. The oxidation of the anode is prevented and the performance and life of the cell are increased.

Abstract: PROBLEM TO BE SOLVED: To provide a method for recovering terbium of high purity. SOLUTION: A terbium-containing material (terbium target scrap for magneto- optical disk, for example) is dissolved in hydrochloric acid and electrolysis is executed by using an obtained soln. as an electrolytic soln. in a closed vessel while blowing an inert gas therein to reduce dissolved oxygen and dissolved chlorine in the soln. respectively to <=10 ppm. After removing impurities, an electrolytic filtrate is treated by charging HF to obtain terbium fluoride. Otherwise, the electrolytic filtrate is treated by charging oxalic acid to obtain terbium oxalate and terbium oxalate is calcined to obtain terbium oxide. Then terbium fluoride or terbium oxide is subjected to reduction.
