Abstract: A noncontact seal for a donor roll in an electrophotographic printing machine. The seal is fixed in the developer housing and envelopes each end of the donor roll but does not contact the donor roll. The small space does not allow a positive airflow sufficient to cause toner particles to be emited from the developer housing so as to contaminate the other portions of the printing machine. The seal is made of a low friction material such as DELRIN.RTM. so that toner particles do not stick to the seal and cause a buildup that would be detrimental to the photoreceptive member.

Abstract: A pixelized scintillation layer is taught in which high aspect ratio columns of scintillation material are formed. The columns may be sized and spaced to correspond to the sizing and spacing of an underlying sensor array, or they may be sized such that there is plurality of columns for each pixel. A method for forming the pixelized scintillation layer includes the step of forming openings such as wells, vias, or channels in a body, for example by etching a thick photoresist, ion beam etching, anodic etching, etc., and the step of filling the openings with scintillation material. A completed image sensing apparatus is also taught.

Abstract: Disclosed is a multimedia database for use in distributed network environments. A query processing module transforms user queries into search transformations that can be used for indexing; an attentional selection module records salient information represented in images by a hierarchy of feature maps, saliency maps and combined saliency maps; a declarative memory comprises active modules that update the representations acquired over time for the same images, as well as across images, to cluster, categorize and organize information extracted from different images by the attentional selection module; and an indexing mechanism utilizes the search transformations from the query processing module to search the declarative memory for an answer to a user query.

Abstract: A multiple-wavelength laser diode array is described. A wavelength span of several tens of nanometers is achieved through band-filling of a quantum well active region. A multiple-wavelength array is formed by selectively introducing different amounts of optical loss into the array elements, to affect the threshold current density. With minimum losses, the laser oscillates at a long wavelength, while an element with high loss will undergo more bandfilling and be forced to emit at a shorter wavelength. To illustrate the structures which incorporate these additional, selective losses, a 2-red-wavelength AlGaInP laser array is described. In preferred embodiments, increased optical loss is achieved in an SBR type laser by narrowing the ridge region, or by reducing its thickness. In another type of laser, increased optical loss is achieved by a very thin upper cladding layer causing increased optical absorption in a close overlying cap or metal layer.

Abstract: Controlled cilia are provided to move an object. Each of the cilia, which are made of an elastic material, are fixed over a substrate and moved between a relaxed position away from the substrate and a retracted position near the substrate to move an object relative to the substrate. The cilia are moved between the relaxed and retracted positions by an electrostatic force or heating of the cilia. The cilia are formed from a material that is initially fixed to a substrate and has an inherent stress gradient. A portion of the material is released from the substrate and the inherent stress gradient forces a free portion of the cilia away from the substrate.

Abstract: In a digital printing apparatus in which primary colorants are selected by an error-diffusion process, a method takes into account situations in which a colorant is selectable from within the gamut defined by certain other primary colorants. In the case of a printer in which, in addition to CMYK colorants, a mid-gray colorant is also selectable, the method avoids the problem in which an error-diffusion algorithm mandates the simulation of colors outside the gamut.

Abstract: A file management system includes a file link control section for relating earlier and later version files to files and a version group information getting section for getting a version group consisting of files having specific relationship with a specified file based on relation information. The file link control section relates the files to each other only with the file identifiers of the earlier and later version files and enables highly flexible registration and deletion in version relationships, and linking and separating of version groups associated with the registration or deletion. The version group information getting section traces the relation information for getting file information.

Abstract: Simulated photographic prints are created using xerographic imaging. A transparent carrier having a xerographically formed mirror image fused thereto is bonded to a plastic substrate through the use of heat and pressure. The transparent carrier and the plastic substrate passed through a heat pressure fuser to form the finished print.

Abstract: A method of making a substrate in which sets of optically anisotropic spheroidal balls are disposed, as for use in an electrical twisting ball display. First and second sets of spheroidal balls, are deposited on a receiving surface composed of an elastomer substrate material in an adhesive state, the spheroidal balls thus deposited adhering to the receiving surface. Balls of the first and second sets are physically distinguishable from one another. Balls of the first set can be deposited in a first arrangement, and balls of the second set, in a second arrangement. Each ball of each set has an optical anisotropy and an anisotropy for providing an electrical dipole moment, the electrical dipole moment rendering the ball electrically responsive such that when the ball is rotatably disposed in an electric field while the electrical dipole moment of the ball is provided, the ball tends to rotate to an orientation in which the electrical dipole moment aligns with the field.

Abstract: A color image forming method of the present invention includes at least an image forming step in which a color image formed by a transparent toner with at least one kind of fine particles of 5 to 30% by volume being contained in a binding resin and a color toner is formed on a transfer material and a heat-fixing step for heating and fixing the color image onto the transfer material. As a result, graininess, color reproducibility, smoothness, and fixing strength are synchronously fulfilled sufficiently without being deteriorated and an arbitrary glossiness can be uniformly reproduced on the transfer material without depending on image density.

Abstract: A thermal ink jet printhead is improved by providing a heater resistor which is mechanically isolated from overlying nitride and tantalum layers by growing a thin buffer oxide layer on the surface of the resistor heater layer. The introduction of the buffer oxide layer permits a thinner nitride layer which, in turn, reduces electrical resistance changes which would otherwise be introduced into the resistor arrays by mechanical stress after the nitride layer is deposited.

Abstract: The present invention describes a method for automatic cropping of images containing regions where intensity levels are uniform and other regions where intensity levels vary considerably. An image to be automatically cropped is scaled down to a grid and divided into non-overlapping blocks. The mean and variance of intensity levels are calculated for each block. Based on the distribution of variances in the blocks, a threshold is selected for the variance. All blocks with a variance higher than this threshold variance are selected as regions of interest. The regions of interest are then cropped to a bounding rectangle.

Through application of an electrolysis voltage between the work piece and the electrode with the electrolyte interposed between them, a passive state film is formed on the surface of a to-be-cut part of the work piece. Then, the passive state film on the surface of the to-be-cut part of the work piece is cut.

Abstract: A distributed printing system that more optimally distributes job requests within a distributed printing system based on more detailed information about the particular attributes of each output device. In particular, additional printer attributes are used that allow greater utilization of a plurality of attached printers having differing capabilities. These attributes include "max-concurrent-jobs-processing" (MCJP), "number-of-jobs-on-device" (NJOD) and "number-of-cascaded-jobs" (NCJ), and a attribute value "saturated" for the attribute "printer-state". The attribute MCJP is an integer value that is based on the capabilities of the printer. NJOB and NCJ attributes allow monitoring of jobs sent to each printer for supported and unsupported printers. If NJOB or NCJ are greater than MCJP, then the attribute "printer-state" is set to "saturated", prohibiting further spooling of print jobs to that particular printer.
