    摘要: A method of milling cerium compound by means of a ball mill using a milling medium, characterized in that ratio Hb/r of radius r of a cylindrical ball mill container and depth Hb of the milling medium in the ball mill container disposed horizontally ranges from 1.2 to 1.9, and the ball mill container is rotated at a rotational speed which is 50% or less of critical rotational speed Nc=299/r1/2 of the ball mill container converted from the radius r expressed in centimeter. The milling method can be carried out in a wet or dry process, and the cerium compound is preferably cerium oxide. The method can be also applied for producing a cerium compound slurry.

    摘要: A gas floating-transporting apparatus transports a material to be treated along a predetermined direction in a thermal space so as to thermally treat the material to be treated. The apparatus includes a gas floating mechanism and a transporting mechanism. The gas floating mechanism includes a gas ejection device which expels the gas toward a portion of the material to be treated on which a floating force is acted so as to float the material to be treated, and a gas supply device which supplies the gas to the gas ejection means. The transporting mechanism includes an abutting member which abuts a trailing end of the floated material to be treated and moves along the predetermined direction, and which pushes the material to be treated by the movement thereof, whereby the floated material to be treated is moved along the predetermined direction.

    摘要: Cooling operation is performed so as to keep a freezer at a selected temperature. Moreover, if the cooling operation enters a phase where the freezer temperature is higher than the selected temperature by a predetermined deviation or more, not only the deviation temperature but also an accumulated time obtained by accumulating the time periods during which the cooling operation is performed at the deviation temperature or higher are stored. In addition, when an instruction signal to indicate an accumulation is input, the stored accumulated time and deviation temperature are read out and indicated on a segment indicating section (7S).
