摘要： In a low-pressure casting in which molten metal is introduced into a cavity of a casting mold under a pressure applied to the surface of the molten metal according to a preset reference pressurizing pattern, the reference pressurizing pattern is corrected when that the cavity has been filled with molten metal is detected and the pressure applied to the molten metal surface is controlled according to the reference pressurizing pattern after the correction. The pressure difference between a set pressure at a predetermined time in the reference pressurizing pattern after the correction and a set pressure at the corresponding time in the reference pressurizing pattern before the correction, is calculated and a set pressure for the period up to the time the cavity is filled with molten metal in the reference pressurizing pattern for the next casting cycle is corrected on the basis of the calculated pressure difference.

摘要： An object of the present invention is providing a method for producing formic acid under mild reaction conditions and by a simple procedure. As a means for achieving the object, the method for producing formic acid of the present invention is characterized by a reaction between carbon dioxide and hydrogen in the presence of an ionic liquid. According to the present invention, it is possible to generate formic acid effectively, because the method does not require that carbon dioxide be brought into a supercritical state and because no basic substances are required to be added to the reaction system.

摘要： A low-pressure casting apparatus includes a casting mold having upper and lower molds, a lower mold platen to which the lower mold is fixed, a molten metal holding furnace which holds molten metal to be supplied to a cavity in the casting mold and is disposed in a position offset from the casting mold, a cutaway portion which is formed in the lower mold platen to open toward the furnace and a molten metal supply pipe which extends obliquely upward through the cutaway portion from the furnace to the lower mold to connect the furnace to the cavity. The molten metal supply pipe is arranged to connect the casting mold and the furnace with the molten metal supply pipe supported on a support table and the support table is provided with a pressing mechanism which presses the pipe against the furnace to connect the furnace-side end of the pipe to the furnace.
