摘要:
There is disclosed a chuck apparatus for holding and shaping a hollow, flexible, endless substrate during dip coating comprising: (a) a hollow, flexible bladder adapted to be disposed within the substrate; and (b) a first spindle and a second spindle which are partially disposed within the bladder, the second spindle being movable to press the bladder against the substrate and to shape the bladder and the substrate into an elongated shape.
摘要:
An electroforming process and apparatus for creating a nickel or like substrate encapsulated by another material to prevent wear to the nickel substrate. The encapsulation of the nickel substrate requires encapsulation of the inner and outer diameter of the nickel substrate. The encapsulating material must adhere to the nickel substrate. Encapsulation of the nickel substrate prevents exposure of the nickel and thus avoids the hazardous nickel dust particles that can occur when the nickel is exposed.
摘要:
There is disclosed an electrostatographic imaging member comprising: (a) a supporting substrate including an electrically conductive surface; (b) a nickel containing layer comprised of nickel, oxygen, and sulfur, wherein the nickel containing layer is the sole charge blocking layer; and (c) at least one electrostatographic imaging layer.
摘要:
A process is disclosed for fabricating a photoconductive member comprising: depositing a photoconductive material and a charge transport material on a substrate, sequentially in any order, or simultaneously, wherein the photoconductive material, the charge transport material, or both, are electrophoretically deposited onto the substrate from a liquid composition.
摘要:
There is disclosed an electrostatographic imaging member comprising: (a) a substrate; (b) a charge blocking layer comprised of nickel hydroxide and nickel oxide, wherein the nickel hydroxide content is at least about 10% based on the number of the nickel hydroxide and the nickel oxide molecules; and (c) a least one imaging layer.
摘要:
An electrophotographic photoreceptor is disclosed which is provided with an anti-corrosion layer on the interface between the substrate surface and hole blocking layer. The photoreceptor has high mechanical strength and minimizes defects in print for longer periods of time.
摘要:
There is disclosed a dip coating method comprising: (a) shaping the widths of a plurality of hollow, flexible, endless substrates into an elongated shape and arranging the plurality of the elongated substrates into a configuration for dipping into a coating solution of a single coating vessel prior to (c); (b) dipping the plurality of the substrates having the elongated shape into a coating solution disposed in the coating vessel; and (c) raising the plurality of the substrates having the elongated shape from the coating solution, thereby resulting in coated substrates.
摘要:
An electrostatographic imaging structure is provided having at least one distinct outer layer including a rotary drum having an outer peripheral surface, a retainer either separate from or a part of the drum or a hold down mechanism, and a photosensitive member held down to the peripheral surface of the drum by the retainer or hold down mechanism.
摘要:
The enclosed an electrostatographic printing apparatus including: (a) an imaging member capable of retaining a latent image, wherein the imaging member includes an imaging layer on a substrate comprised of a magnetic material with a magnetic permeability of at least 1.001; (b) charging apparatus for charging the surface of the imaging member, thereby resulting in a charged surface; (c) exposure apparatus for exposing a portion of the charged surface to radiation, thereby substantially discharging the exposed portion, wherein the substantially discharged, exposed portion corresponds to the image area of the latent image; and (d) a single component development apparatus for depositing toner particles on the substantially discharged, exposed portion of the imaging member.
摘要:
A corona generating device of the type having a conductive shield partially surrounding a corona discharge electrode is provided with heating element. The heating element raises the surface temperature of the conductive shield to reduce or eliminate the adsorption of corona effluents and thereby minimize or prevent copy quality defects.
