    • 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.
    • 通过加热含有钠盐的盐混合物制成熔体。 将熔体设定为高于盐混合物的液相线温度的温度,并倒入用于消耗性芯成型的模具中。 将熔体完全倒入模具中的温度设定在不超过盐混合液的液相线温度30℃的范围内。通过使模具内部的熔体固化来模制用于铸造的消耗性盐芯。 这使得可以更稳定地获得由通过熔融和模制钠等盐形成的盐浇铸产品的水溶性消耗性盐芯的强度。

    • 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.
