Title: Method for decontaminating the surface of a component
IPC: G21F9/28
Filed: 1999-11-02
Abstract: A method for decontaminating a surface includes the steps of bringing a surface of a component formed of an unalloyed steel or a low-alloy steel into contact with a solution containing an oxalic acid for dissolving a contaminated layer from the component. Ions of divalent iron in the solution instantly form a protective layer on exposed surfaces. Iron(III) oxalate is converted into iron(II) oxalate and carbon dioxide by irradiation with UV light in order to provide ions of divalent iron. Subsequent to dissolving the contaminated layer, the protective layer is dissolved by lowering the level of the ions of the divalent iron in the solution. The ions of the divalent iron and the substance having caused the contaminated layer are bound to an ion exchange resin.

Abstract: PURPOSE: A full charge controlling method of a battery for rapid charge is provided to fully charge and safely use the battery without over charging and life time reducing. CONSTITUTION: In a full charge controlling method of a battery for rapid charge, variation of a terminal voltage per a unit time is detected by a detector, e. g., 20-25 times per a second, while a current is supplied to charge the battery after the battery is turned on and a timer is started. When the variation of the terminal voltage per the unit time increases rapidly and then decreases steeply, a microprocessor determines that the battery is fully charged and controls the charging current to the battery to be blocked. When the detector can not detect the variation of the terminal voltage per the unit time, the microprocessor controls the charging current to the battery to be blocked if the timer reach a preset value.
