Abstract: A charge transport layer composition for a photoreceptor includes at least a binder and a charge transport material of about 100% to about 40% by weight of a total of the charge transport layer N,N-dimethylphenyl)-4-biphenylamine and about 0% to about 60% N,N?-bis(3-methylphenyl)-(1,1?-biphenyl)-4,4?-diamine, and wherein the total charge transport material in the composition is 48% or less of the total solids of the composition. The charge transport layer forms a layer of a photoreceptor, which also includes an optional anti-curl layer, a substrate, an optional hole blocking layer, an optional adhesive layer, a charge generating layer, and optionally one or more overcoat or protective layers.

Abstract: An electrostatographic imaging member having a charge-retentive surface and a substrate, an imaging layer to receive an electrostatic latent image thereon, wherein the imaging layer is positioned on one side of the substrate, and an anti-curl backing layer positioned on the substrate on a side opposite to that of the imaging layer, wherein the anti-curl backing layer has a polymer binder and lignin sulfonic acid doped polyaniline, and an image forming apparatus having the above imaging member or photoreceptor to receive an electrostatic latent image on a charge-retentive surface of the photoreceptor or imaging member; a development component to apply toner to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface; a transfer member to transfer the developed image from the charge-retentive surface to a copy substrate; and a fixing component to fuse the developed image to the copy substrate.

Abstract: Process for producing a corrosion-resistant liquid level control plate for the printhead of an aqueous ink jet printing machine. A corrosion-resistant metal alloy base is used, having an undersurface and an upper surface and having closely-spaced ink jet nozzles therethrough. Each of the nozzles has a micro-orifice at the undersurface surrounded by a lip area at the bottom of upwardly and outwardly tapered walls opening at the upper surface. The present process comprises forming the lip areas of metallic gold, encapsulating the upper surface of the metal alloy base including the gold lip areas and the tapered walls with metallic gold to form a corrosion-resistant, hydrophobic surface layer thereover. Thereafter the undersurface is coated with metallic chromium to render it hydrophilic.

Abstract: A method and apparatus for managing effectively data and command buffers in an I/O subsystem utilizes a content addressable memory (CAM) array (36) having a plurality of CAM storage locations (SL1 . . . SLn). The CAM array is used to store a plurality of SCSI Nexus entries and generates a unique address pointer when there is a match between an incoming SCSI Nexus value and one of the plurality of SCSI Nexus entries. A command buffer (24) or user data buffer (26) is responsive to the unique address pointer for storing and retrieving the command/data section of a Command Control Block in a corresponding one of a plurality of buffer storage locations. As a result, the host CPU (12) or adapter (22) is relieved of much of the overhead associated with managing these buffers.

Abstract: The cleaning assembly of the present invention is provided with a precleaner. The precleaner precleans and directs the chaff rich mixture from the separating assembly to the chaffer downstream from where the grain rich mixture from the threshing assembly is introduced to the chaffer. The precleaner is mounted to the chaffer and is provided with a step pan section and a louvered cleaning section for precleaning the chaff rich mixture.
