Abstract:
An apparatus including: (a) a substrate including a deposition region and an optional uncoated region, wherein the deposition region includes a level intermediate region disposed between a first end region and a second end region, wherein the first end region includes a first raised surface portion extending above the level intermediate region and extending circumferentially around the first end region in a continuous manner; and (b) a dip coated layer over the entire deposition region.
Abstract:
An apparatus, to be used when an open end of a hollow substrate contacts a coating solution to define a solution free interior portion of the substrate, for controlling the level of the coating solution relative to the substrate interior, the apparatus including: a gas container capable of changing in volume; a channel connecting the gas container to the solution free interior portion of the substrate to allow gas flow in either direction between the gas container and the solution free interior portion; and pressure means for exerting a changeable, continuous pressure on the gas container that automatically exerts an increasingly greater pressure on the gas container as the gas container expands in volume and that automatically exerts a decreasingly lesser pressure on the gas container as the gas container decreases in
Abstract:
It is desired to remove matter on a fluid surface of a tank. The tank defines a circular tank orifice comprising a tank orifice rim, the tank orifice rim containing a fluid surface of a fluid, the fluid overflowing the tank orifice rim to form a fluid overflow, the fluid surface defining a fluid surface center. The matter is removed by discharging from near the tank orifice rim a plurality (n) of jets of the fluid towards the fluid surface center. Any matter on the fluid surface is thereby urged toward the tank orifice rim and eventually removed from the fluid surface by the fluid overflow. In one application, the tank comprises a dip tank and the fluid comprises photoreceptor coating solution or components thereof such as solvents, additives, or both.
Abstract:
A member including for example, a substrate, a charge generating layer, a charge transport layer comprising a poly(phenylsilsesquioxane), molecule, and a film forming binder.
Abstract:
A coating method for a substrate defining a deposition region and an optional uncoated region, wherein the deposition region includes an intermediate region disposed between a first end region and a second end region, the method composed of: (a) dip coating a first layer of a coating solution including a liquid medium and a coating material only over the first end region; and (b) dip coating a second layer of the coating solution over the first layer, the intermediate region, and the second end region in the recited sequence.
Abstract:
An apparatus comprising: (a) a substrate including a level intermediate region disposed between a first end region and a second end region; (b) a first external member disposed circumferentially around the first end region in a continuous manner and protruding above the level intermediate region, thereby resulting in a deposition region including the surface of the first external member covering the first end region, an optional exposed first end region portion, and the intermediate region; and (c) a dip coated layer over the entire deposition region, wherein the portion of the dip coated layer over the first external member and the optional exposed first end region portion is formed prior to the portion of the dip coated layer over the intermediate layer.
