    • The present invention provides a method of producing composite oxide ceramics which is capable of efficiently producing single-phase multi-component metal oxide ceramics having less impurity phase and excellent dielectric characteristics, by a simple process comprising sintering at a low temperature. The method has the steps of mixing a metallic hydroxide or hydrous gel with a plurality of metallic oxide powders to prepare a raw material mixture powder, activating the raw material mixture powder by mechanochemical treatment for grinding the raw material mixture powder with a degree of impact, which provides a centrifugal effect of 15 or more, to form a precursor, and synthesizing composite oxide ceramics by heat treatment of the activated raw material mixture powder (precursor).

    • It is an object of the present invention to provide a particle crushing and sizing apparatus having a sufficiently wide particle crushing and sizing range, capable of being scaled down in size, and having high processing throughput. To achieve the object, a particle crushing and sizing apparatus has, in a casing 1a, a horizontally provided drive shaft 2, a plurality of circular plates 10 fixedly supported with intervals at the drive shaft 2, and stators 5 arranged so as to be opposed to plate faces 10a at lower peripheral edges of the circular plates 10 and each having inclined faces 5b that cause a gap between the plate faces 10a of the circular plates 10 to become narrower toward peripheral edges of the plate faces 10a. The plate faces 10a of the circular plates 10 and the inclined faces 5b of the stators 5 form gap portions A where particles are held, and particle crushing and sizing portions B are formed by the peripheral edges of the circular plates 10 and narrowest gap portions between the peripheral edges of the circular plates 10 and the inclined faces of the stators 5.
    • 本发明的目的是提供一种具有足够宽的颗粒破碎和上浆范围的颗粒破碎和定型装置,能够在尺寸上缩小并且具有高处理量。 为了实现该目的,颗粒破碎和定型装置在壳体1a中具有水平设置的驱动轴2,在驱动轴2上以间隔固定地支撑的多个圆形板10和布置成为 与圆板10的下周缘处的板面10a相对,并且每个具有倾斜面5b,使得圆板10的板面10a之间的间隙朝向板面10a的周边边缘变窄。 圆板10的板面10a和定子5的倾斜面5b形成保持颗粒的间隙部分A,并且颗粒破碎和上浆部分B由圆板10的周缘形成,最窄的间隙 圆板10的周边边缘和定子5的倾斜面之间的部分。

    • A tow feeding apparatus which requires no continuous observation, shortens the reset time when tow is wound around pinch rolls for feeding into a case, and operates safely, includes guide rolls for leading a tow to a winding roll or pinch rolls, a winding roll apparatus provided between the guide rolls and pinch rolls at a normal position for winding up a tow around a winding roll when wrapping trouble occurs at the pinch rolls. A pinch roll apparatus for feeding the tow from the guide rolls through the winding roll apparatus into a case, and a transport device for transporting the winding roll apparatus from the normal position to a reset position behind the pinch roll apparatus when wrapping trouble occurs. A cutter shears the tow along the tow route before the pinch roll apparatus. An exchanger for substituting the pinch roll apparatus with another set of pinch rolls, and a detector for detecting wrapping of a tow around the pinch rolls are further included. A controller receives a signal from said detector to actuate the cutter and the driving motor for driving the winding roll, stops the pinch roll apparatus, drives the exchanger, actuates the transport device for moving the winding roll apparatus from the normal position to the reset position, starts the pinch roll apparatus at the same time as the winding roll apparatus is stopped, and returns the winding roll to the normal position.
