    摘要: A melt is made by heating a salt mixture containing a salt of sodium. The melt is set at a temperature higher than the liquidus temperature of the salt mixture, and poured into a mold for expendable core molding. The temperature when the melt is completely poured into the mold is set within a range not exceeding the liquidus temperature of the salt mixture by 30° C. An expendable salt core for casting is molded by solidifying the melt inside the mold. This makes it possible to more stably obtain the strength of a water-soluble expendable salt core for casting made of a salt cast product obtained by melting and molding salts of sodium and the like.

    摘要: An electronic device includes a housing; a touch surface exposed to the surface of the housing; a displacement detector; a rotational movement detector; a linear movement detector; a signal generator; and a control unit. The displacement detector detects a displacement of an object touching the touch surface. The rotational movement detector detects a rotational movement of the object based on the displacement. The linear movement detector detects a linear movement of the object based on the displacement. The signal generator generates an operation signal corresponding to the rotational movement and the linear movement. The control unit controls an operation to be performed based on the operation signal.

    摘要: An expendable salt core has the shape of a water jacket by, e.g., die casting using a salt of bromine and at least one of sodium and potassium, and a salt of carbonic acid and at least one of sodium and potassium. The expendable salt core is formed to contain at least one of potassium and sodium as a cation, and bromine and carbonic acid as anions. For example, the expendable salt core is formed by casting using a melt obtained by melting a salt mixture of sodium bromide and sodium carbonate.

    摘要: A salt core (2) is formed by casting a mixed material of a salt material and a ceramic material. Any one of a chloride, bromide, carbonate, and sulfate of potassium or sodium is used as the salt material. As the ceramic material, granular one having a density falling within a range of 2.2 g/cm3 (exclusive) to 4 g/cm3 (inclusive) is used.

    摘要: In a method for producing a salt core for casting formed by a molten salt made of a salt mixture containing sodium salt, first, a melt is formed by heating a salt mixture. Next, a mold for core molding is heated to a temperature higher than about 0.52×Tm and lower than about 0.7×Tm. Note that Tm represents the liquidus temperature of the salt mixture as an absolute temperature (K). Then, the melt is poured under pressure into the mold heated as described above. A salt core for casting is molded by solidifying the melt inside the mold.
