Patent ID: 6872260

Claim:
A deposited-film forming apparatus comprising an evaporating section for at least one depositing material selection of the group consisting of aluminum, zinc, tin and magnesium and an alloy containing at least one of these metal components, and a plurality of tubular barrels formed of a mesh net for accomodation of rare earth metal-based permanent magnets, on each of the surfaces of which a depositing material is to be deposited, said evaporating section and said tubular barrels being mounted in a vacuum-treating chamber, wherein said tubular barrels are detachably supported by support shafts provided at each side of each tubular barrel circumferentially outside a horizontal rotational axis of a support member rotatable about said rotational axis, for rotation about said rotational axis, so that the distance between said tubular barrel rotated about said rotated about said rotational axis of said support member and said evaporating section is varied by rotating said support member, wherein said evaporating section receives electric current and heats the at least one depositing material by resistance heating, with the at least one depositing material being molten at said evaporating section.
