To keep rotation direction is as usual, new function which revolving direction is changeable either clockwise or anti-clockwise for revolution.
Under vacuum pressure, it may change material property, however it enables to achieve high precision degassing even atmospheric pressure condition.
Drastically increased revolving speed of rotation!
To keep centrifugal force of revolution, it enables to achieve setting which revolving speed pf rotation can be surpassed to revolving speed of revolution.
Mixing force is drastically enhanced, thus it can correspond to various materials case.
