Abstract
A process for surface-treating a plurality of works which includes the step of surface-treating the works in a treating chamber, while rotating the works about their axes in spaced apart states, wherein the surface treatment is a vapor deposition on a sintered article and the support member includes plate-like elements openably and closably foldable in a lengthwise direction, the plate-like elements defining a plurality of narrow sections each having a length in opened states corresponding to an inside diameter of a work. The support member may also include an upper cage and a lower cage which are openable and closable in a lengthwise direction.

A process for surface-treating a plurality of works comprising the step of surface-treating the works in a treating chamber, while rotating the works about their axes in spaced apart states, wherein the surface treatment is a vapor deposition on a sintered article, said support member comprises plate-like elements openably and closably foldable in a lengthwise direction, and said plate-like elements define a plurality of narrow sections each having a length in opened states corresponding to an inside diameter of each of said plurality of works.
A process for surface-treating a plurality of works comprising the step of surface-treating the works, while rotating the works about a rotational axis in spaced-apart states, wherein said rotation of the works is carried out with the works supported by a support member rotated about a rotational axis, said support member comprises plate-like elements openably and closably foldable in a lengthwise direction, and said plate-like elements define a plurality of narrow sections each having a length in opened states corresponding to an inside diameter of each of the plurality of works in opened states.
A process for surface-treating a plurality of works comprising the step of surface-treating the works, while rotating the works about their axes and a rotational axis in spaced-apart states, wherein said rotation of the works about the rotational axis is carried out with the works supported by a support member, said support ember comprises plate-like elements openably and closably foldable in a lengthwise direction, and said plate-like elements define a plurality of narrow sections each having a length in opened states corresponding to an inside diameter of each of the plurality of works in opened states.
