Title:
METHOD FOR FORMING FILM ON SPHERICAL BODY
Document Type and Number:
WIPO Patent Application WO/2014/010434
Kind Code:
A1
Abstract:
[Problem] To provide a method or the like for forming a spherical body such as a golf ball or the like in which the film thickness of an outer cover layer for emitting iridescent light can be formed as thin as possible when the outermost cover layer is to be formed on the surface. [Solution] An electron beam is emitted onto silicon dioxide to form a first film having a low refractive index on the lower surface of a golf ball (7) mounted on a rail (3). The golf ball (7) is moved to a contact member (6) and made to rotate, and an electron beam is emitted again onto a different surface to form the first film on the entire surface. Next, an electron beam is emitted into a crucible (52) containing titanium oxide, and a second film having a high refractive index is similarly formed on the lower surface. The golf ball (7) is moved to the contact member (6) and made to rotate, and an electron beam is emitted again onto a different surface to form the second film on the entire surface.
