Abstract: Provided is a method of, in ladle refining treatment of a molten steel, accurately estimating the molten steel temperature after the ladle refining treatment. An operation method of ladle refining treatment by which ladle refining treatment of a molten steel is performed while continuously measuring a molten steel temperature during operation of the ladle refining treatment of the molten steel comprises setting a time earlier than a scheduled ending time of the ladle refining treatment in a continuous measurement period of the molten steel temperature as a determination timing, and estimating the molten steel temperature at the scheduled ending time on the basis of a change with time of the molten steel temperature in continuous measured data of the molten steel temperature from a start of continuous measurement of the molten steel temperature to the determination timing.

Abstract: A method for processing a fluorine-containing electrolyte solution including a gasification step of gasifying a volatile component of an electrolyte solution including a fluorine compound by heating the electrolyte solution under reduced pressure, a fluorine immobilization step of immobilizing the fluorine component included in the gasified gas as calcium fluoride by allowing the fluorine component to react with calcium, and an organic solvent component collection step of collecting an organic solvent component included in the gasification gas, in which, preferably, after a small amount of water, aqueous mineral acid solution, or the like is added to the electrolyte solution, the volatile component of the electrolyte solution is gasified by heating the electrolyte solution under reduced pressure.

Abstract: A shaft member having an engaging part at a lower part is formed to project from a front edge part of a plate-like fitting main body having a required thickness, and an engaging member having an engaging part at a lower part is mounted to a tip surface of the shaft member, the engaging parts communicating with each other, wherein the fitting main body has a gripping part formed of a through-hole at a central part and pin insertion parts which are formed collinearly in the vicinity of an upper edge part and a lower edge part at a rear side of the fitting main body, and wherein a shaft-member insertion part resisting shear stress is provided at a portion different from the pin insertion parts formed on the upper edge part and the lower edge part.

Abstract: A design method for a building which enables an efficient design or construction and is environment-friendly by suppressing the occurrence of damaged materials to a minimum, and a building which can be constructed at a low cost are provided in such a manner that when the building is designed, a boundary surface in the height direction of a substantially effective width (working width) in an exterior member, a so-called siding panel, which occupies relatively high cost is set to be an indicator for determining an arrangement position of a window, a balcony, a canopy, further a main entrance or the like. When a building 1 is constructed, a lower limit position or an upper limit position of the attachment position of a window 11, a canopy, a balcony, a main entrance and a parapet which are arranged at an outer wall thereof is determined by setting a working width of exterior members 13a to 131 which are used in constructing the outer wall of the building 1 and have a constant shape, as an indicator.
