Patent ID: 8268080

Claim:
An apparatus for preparing composite particulates, comprising: a rotary body having a bottom surface, a side wall, and a flange provided at one end part of the side wall extending perpendicularly from the one end part to face the bottom surface, the flange being provided with an opening through which the rotary body is charged with particulates, the rotary body being operative to contain the particulates to which an adhering material is to be made to adhere, the rotary body including a vapor deposition device in which the adhering material is evaporated by heating to start vapor deposition of the adhering material on the particulates; a centrifugal machine configured to rotate said rotary body as to apply centrifugal forces to said particulates in said rotary body, the rotating speed of the rotary body is greater than 2G as exerted on the particulates; a film thickness monitor for measuring the film thickness of the adhering material having adhered to the particulates in response to the vapor deposition; and an inclination varying device for varying the inclination of said rotary body during coating to an arbitrary inclination angle in the range from an angle at which said bottom surface of said rotary body forms a horizontal surface perpendicular to the direction of gravity, or horizontal position, to an angle at which said bottom surface forms a vertical surface parallel to the direction of gravity, or vertical position, and supporting said rotary body at said arbitrary inclination angle, wherein, the vapor deposition device is configured to direct the adhering material toward a top portion of the rotary body once the inclination varying device rotates the rotary body to said inclination angle, the inclination varying device includes a support member which supports the rotary body, the support member having an axis about which the support member pivots, the rotary body has an axis of rotation that is variable ranging from a position where the axis of rotation is parallel to the direction of gravity to a position where the axis of rotation is perpendicular to the direction of gravity, and the axis about which the support member pivots and the axis of rotation of the rotary body are not parallel.
