There is disclosed a dip coating apparatus including: (a) a single coating vessel capable of containing a batch of substrates vertically positioned in the vessel, wherein there is absent vessel walls defining a separate compartment for each of the substrates; (b) a coating solution disposed in the vessel, wherein the solution is comprised of materials employed in a photosensitive member and including a solvent that gives off a solvent vapor; and (c) a solvent vapor uniformity control apparatus which minimizes any difference in solvent vapor concentration encountered by the batch of the substrates in the air adjacent the solution surface, thereby improving coating uniformity of the substrates.

Dip coating apparatus having a single coating vessel

A system in which a contact cleaning cylinder is brought into moving synchronous contact with the surface of a cylindrical member to be cleaned to clean the surface.

Removal of particulates from cylindrical members

An apparatus is disclosed for internally holding an at least partially hollow substrate having at least one open end. The apparatus includes a member defining a fluid passageway, a normally inflated porous material mounted on the member in communication with the fluid passageway of the member, and a mechanism, in communication with the member, for deflating the porous material, the deflating mechanism being de-energized in response to the porous material being disposed into the opening in the substrate for enabling the porous material to return to being normally inflated to hold the substrate.
