Abstract
Abstract A method and apparatus is disclosed for vapor depositing a thin film of material on image retention surface substrate bodies comprising the steps of positioning a plurality of substrate bodies on a plurality of elongated, horizontally extending support mandrels, rotating each of said mandrels about an associated longitudinal axis thereof while simultaneously transporting said plurality of mandrels in an annular path about a horizontal axis, establishing an evacuated atmosphere about said assembly of mandrels, and vaporizing a material which is positioned in a planar array of crucibles located within a path defined by the annular travel of said mandrels.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
175 words
Apparatus for the vapor deposition of a layer of material on substrate bodies comprising: a generally vertically oriented support table adapted for rotation about a horizontal axis; means for rotating said support table; a plurality of elongated horizontally oriented mandrels rotatably supported in an annular array on said support table; means for rotating each of said mandrels about a longitudinal axis thereof; each of said mandrels adapted for receiving, supporting, and rotating therewith a plurality of substrate bodies; means for vaporizing a predetermined quantity of material which is to be deposited upon said substrate bodies; heating means including an electrode mounted and adjustably positioned adjacent the annular path of travel of said mandrels and extending substantially coextensively with the elongated mandrels, means for applying an electric potential between said electrode and said subStrate support bodies for establishing a glow discharge between said electrode and said substrate support bodies for forming an interface barrier layer on said support bodies; and means providing an evacuated enclosure for said heating means, mandrels, and the substrate bodies supported thereon.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
24 words
The apparatus of claim 1 wherein said means for vaporizing said material is positioned substantially outside an annular path of travel of said mandrels.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein said means for vaporizing said material is positioned substantially within an annular path of travel of said mandrels.
