Abstract: A heat and pressure fuser and a Release Agent Management (RAM) system therefor. A dual function RAM system is provided. The dual function RAM system supplies functional release agent material having a relatively high concentration of functional chains (in the order of 0.05 to 0.4 mol %) to an elastomeric fuser member as well as release agent material having low funtionality or no functionality. The elastomeric fuser member may contain metal oxide particles. The low functionality release agent is relatively non-reactive. Depending on whether the elastomeric member contains the metal oxide particles, the functional chains of the high concentration release agent material which are periodically supplied to the fuser roll surface either attach to the metal particles exposed at the surface of the fuser roll by chemical bonds or to the elastomeric material itself. The non-reactive chains adhere to the functional chains by much weaker physical (such as van der Waals) chains.

Abstract: An electrophotographic photosensitive element having S-type photo-induced potential decay characteristics and an electrophotographic apparatus using the photosensitive member are provided.The photosensitive member comprises a charge generation layer and a charge transport layer on an electroconductive substrate. The charge transport layer contains a polymer in a phase separated state with a modulated structure, comprising an electrically inactive phase and a charge transporting phase. The amount of exposure required for 50% potential decay is less than 5 times the exposure amount required for 10% potential decay. The modulated structure includes, for example, a mixture of insulating polymer and charge transporting polymer and the like. The modulated structure can be formed by the method of separating a homogeneous phase of these polymers into two phases.

Abstract: Parts of documents are retrieved using the entire context of selected documents. Classification unit designation section performs the designation of a classification unit. A logical structure analysis section analyzes the logical structure of the documents read-in from a document storing section where the documents are stored. A fundamental vector generation section partitions the logical structure of the documents by means of the classification unit, extracts keywords, and generates fundamental vectors. A heading vector generation section extracts key words from the headings of the structural elements that are arranged in higher level of structure than the structural element of the classification unit that was the target of fundamental vector generation, and generates heading vectors. A vector synthesis section synthesizes fundamental vectors and heading vectors, and generates composite vectors.

Abstract: A photoreceptor includes a supporting substrate and an outer layer on the photoreceptor, the outer layer including silicone oil uniformly dispersed as vesicles in a continuous film forming polymer matrix. This photoreceptor is used in a xerographic copier/printer machine and contributes to a longer operating life of the machine by providing continuous lubrication, decreased friction and decreased wear of the interaction of the photoreceptor and other machine parts. This photoreceptor is prepared by incorporating silicone oil and at least one film forming polymer in at least one solvent, removing the solvent and forming a dried outer layer in which the silicone oil is phase separated from the other components of the top layer forming small vesicles which are uniformly dispersed in the continuous film forming polymer matrix.

Abstract: The nucleation efficiency of a thermal ink jet printhead is improved by forming a heater element with a planar surface. A heater resistor, polysilicon in a preferred embodiment, has an irregular surface which can trap gas or vapors in the cracks or crevices. When the heater resistor is pulsed, the nucleation temperature is reduced by these trapped vapors requiring an increase in electrical input to the resistors, thereby reducing efficiency. The invention recognizes that a heater resistor with a planar surface in contact with an ink layer results in a higher nucleation temperature and increased efficiency. In one embodiment, a phosphosilicate glass (PSG) is flowed directly onto the resistor surface forming a planarization layer. Subsequent deposition of tantalum substantially replicates the underlying topography creating a heater resistor with a smooth surface adjacent the ink.

In one embodiment, the semiconductor chips are thermal ink jet printhead subunits.

Abstract: An apparatus and method for slowing down the ejection velocity of the print media into an output tray, without the use of active velocity control of the exit nip or interface, utilizing a non-circular drive roll running against a leaf spring. The regions of contact of the non-circular drive roll are driven at a velocity slower than the incoming sheet velocity, and the spaces between the regions of contact are used to enable relaxation of buckling generated in the print media (e.g. print sheets). The print media travels at the velocity of the upstream nips until they are entirely under the control of the non-circular drive roll exit nip, thus enabling the sheets to be ejected from the exit nip, at a slower velocity, improving stacking registration.

Abstract: The present invention is an apparatus that develops a latent image recorded on a surface with toner. An electrically biased electrode member in the development zone between the photoconductive member and the donor roll detaches toners from the donor roll so as to form a toner powder cloud in the development zone. The electrical bias applied on the donor member is an asymmetrical wave. Toner from the toner powder cloud develops the latent image.

Abstract: In the UNIX Operating System, modifying the kernel routine Physio, to enable a single system call to set up a number of concurrent direct memory access (DMA) channels between memory and the data buffers of a device. Many character device drivers use the UNIX Physio facility for I/O. The traditional implementation of Physio handles I/O in a serial manner by performing gather-write or scatter-read operations. This invention is an enhancement to Physio to support parallel I/O operations.

Abstract: Embedded data blocks, such as block formatted glyph code patterns, are dimensionally characterized by address codes. The address codes may be spatially encoded as sync glyphs embedded in a glyph pattern including data glyphs. The encoded glyph pattern is read to recover the distributed dimensional labeling information for the embedded data blocks from the embedded sync glyphs. The encoded glyph pattern may be represented by slash-like symbols that appear gray under normal viewing.

The first tray is overlying the second and is pivotally cantilever mounted about a first pivot axis so that when a sheet feeding jam occurs the first tray readily manually pivots upwardly about the first pivot axis to expose sheets in the second tray, and also a camming surface on the tray, which may be provided by edge guides adjacent the first pivot axis, engages and automatically unlatches, with high leverage, a top cover of the enclosed sheet feeding path unit, which top cover pivots open about a second pivot axis spaced from the first. The top cover may be spring loaded to automatically pop further open for full exposure and removal of sheets inside the unit upon said automatic unlatching.
