Abstract: A tape cassette has a tape extending from one tape reel around a tape engagement area of the periphery of a guide member and to another tape reel when the tape is in a normal operating position when the cassette is in a tape drive. The cassette includes a tape lift off mechanism which is mounted for rotatable movement around the periphery of the guide member from the normal tape operating position, where the tape lift off mechanism is out of contact with said tape, to a tape storage position where the tape lift off mechanism engages the tape and disengages the tape from at least a portion of the tape engagement area of the guide member when the cassette is removed from the tape drive. In addition to the tape lift off mechanism, a brake mechanism is provided that engages flanges of both tape reels when the cassette is removed from the tape drive to prevent the reels from rotating during storage of the cassette.

Abstract: A system for concurrently imaging the first and second sides of different sequential duplex documents in alternating image lines alternating between the first and second imaging stations. This system is shown in a system for imaging both of the first and second opposing sides of duplex documents with higher productivity, with a generally "V" shaped low profile document sheet feeding path with first and second arms merging at a base position having a document reversing system, for sequentially feeding documents from an input tray through the first arm to the base position, and then back through the second arm to an output tray. A first imaging station is in the first arm for imaging the first sides of the documents, and a second imaging station is in the second arm for imaging the second sides. Both imaging stations have a simple, partially shared fixed elements optical system mounted entirely inside the document path, which can share a single electro-optical digital imager.

Abstract: A method and apparatus for drying liquid ink deposited, in response to image data, on a recording medium moving along a path at a predetermined rate. A recording medium having liquid ink deposited thereon is moved past a dryer in multiple passes to dry areas of high ink coverage. Ink characteristics are optimized for minimum print defects by determining the time between printing and drying. In the case of text only images only one pass through the dryer is required. For areas of high ink coverage, however, multiple passes through the dryer are required and completed either by reciprocation or recirculation at the same predetermined rate.

Abstract: An apparatus for developing a latent image recorded on a surface is disclosed. The apparatus includes a housing defining a chamber storing a supply of developer material comprising toner. The toner donor member spaced from the surface and being adapted to transport toner to a region opposed from the surface. A magnetic brush conveys the developer material in the chamber of said housing onto said donor member. An electrode member near the surface of a donor roll is electrically biased to detach toner from said donor member as to form a toner cloud for developing the latent image. A vibration system, operatively coupled to said donor member vibrates toner on the surface of the donor member, said vibration system coacting with said electrode member to detach toner from said donor member.

Abstract: A system for logically segmenting document elements from a document includes an input port for inputting a signal representing the document image, a computer having a document structural model, a document white region extraction system that extracts major white regions separating document elements in the input document image, and a string translation device that generates matching one-dimensional data string that corresponds to the extracted major white regions in a document image, a comparison device that selects the optimum path through a finite state machine representing acceptable column layouts for the source document, and a columnar layout identification device that identifies the column layout defined by the optimum path. Then, the identified column of document elements may be processed to logically tag or extract document elements.

Abstract: A method of correcting out-of-range 8-bit pixel values, which should range from 0 to 255 by successively finding an out-of-range pixel, correcting it by adding (subtracting) an amount to restore that value to 0 (255), and then subtracting (adding) an equal amount to an adjacent pixel or pixels. An alternative, most useful for text, is to find an out-of-range pixel, and then replace it, and all adjacent pixels that are within a predetermined limit of 0 (255), with 0 (255).

Abstract: Hydroxygallium phthalocyanine crystals having intense diffraction peaks at Bragg angles (2.theta..+-.0.2.degree.) of 7.5.degree., 9.9.degree., 12.5.degree., 16.3.degree., 18.6.degree., 25.1.degree. and 28.3.degree. in Cuk.alpha. characteristic X-ray diffractometry, a process for producing the same, and an electrophotographic photoreceptor containing the same are disclosed. The hydroxygallium phthalocyanine crystals are obtained by once preparing impurity-free hydroxygallium phthalocyanine having intense X-ray diffraction peaks at specific Bragg angles, followed by a solvent treatment for crystal transformation, in which the impurity-free crystals are prepared by using excess phthalocyanine ring-forming compound in the synthesis of starting gallium phthalocyanine or by removing insoluble matter from the acid paste of starting gallium phthalocyanine.

Abstract: An encoder for encoding four bits of uncompressed data in one clock cycle generates one code or in parallel a plurality of codes if the bits can be represented by a code or by a plurality of codes and keeps the bits that can not be represented by a code unaltered. On the following clock cycle, the unaltered bits from the previous clock cycle will be combined with a new set of four bits of data and the cumulative bits will be converted to a code if they can be represented by a code and if they can not be represented by a code, they will be stored until the next clock cycle. The process of storing the cumulative number of bits will be continued until the cumulative number of bits can be represented by a code.

Abstract: An electrocapillary color display sheet is disclosed which utilizes a plurality of sets of different color droplets between two sheets in which each set of droplets will create a pixel of an image. Each set of droplets has at least two droplets in which each droplet has a different color. Each droplet of each set is immiscible with the rest of the droplets of the set. There is an electrode on each sheet which corresponds to each set of droplets. There is also an addressable electrical connection to each droplet. By selectively activating droplets of each set of droplets and its corresponding electrodes on the two sheets, at least one of the droplets of the set will expand in a space commonly shared by the droplets of each set to create a colored pixel.

Abstract: A large array or pagewidth printhead fabricated from printhead elements or subunits. The printhead subunits are butted together at either adjacent channel elements or adjacent heater elements to form a pagewidth printhead. The butting element, either heater or channel element, is slightly wider than the non-butting element thereby providing gaps between the non-butting elements of a printhead element array. Where channel elements are used as the butting element, gaps between the heater elements provide for reduction or elimination of potentially damaging thermal compressive forces between adjacent heater elements. Where heater elements are used as the butting element, structural strength is increased since the heater wafer is stronger than the channel wafer. In addition, the width of the polyimide wall at the edges of the heater wafer is increased providing greater protection for thermal transducers located at the edges of individual heater elements.
