Patent EP-0563523-A2 (EP)
Inventor: PAPETTI RICHARD R
IPC: B04C11/00
Filed: 1993-01-27
Abstract: Hydrocyclone separators of the type used to separate contaminants from pulp suspensions in paper mills are connected to feed, accept, and reject conduits using a conduit apparatus in which both feed and accept portions can be made from smooth material. The feed and accept portions include surfaces through which apertures are provided for making connections to the feed and accept nozzles of the hydrocyclones. The smooth material eliminates the tendency of pulp to build up on the conduit walls and in the nozzles, thereby avoiding the problems that can occur when such build ups break loose. The nozzles of the hydrocyclones are preferably attached by placing a resilient sealing member around the circumference of the nozzle, and inserting the nozzle into an aperture formed in the wall of the conduit until the sealing member engages the inside wall of the aperture. The wall of the conduit can include a generally flat portion made from a metal plate material so that the sealing member seals only against the narrow, generally-cylindrical inside surface of the aperture. The wall can also be molded of a plastic material and can have an aperture dimensioned so that a length between the exterior and interior walls changes around the aperture. A manifold is also provided which is useable between the main feed and main accept conduits so that it can either be parallel therewith or transverse thereto.

Abstract: A method and apparatus are provided for specifying layout processing of structured documents in computer-based document handling systems. The method and apparatus allow the specification of the generic logical structure of the structured document in terms of relational attribute grammars. According to the invention, these relational attributes have a binary relationship. The generic layout structure for a class of structural documents is also represented in terms of relational attribute grammars. Coordination grammars, also represented in terms of relational attribute grammars, link the elements of the generic logical structure to the generic layout structure. By coordinating the layout and logical structures, many solutions are available. Preferential specifications are developed to resolve any potential ambiguities between the many solutions, and to select a preferred solution. The logical structure is then converted to a layout structure using the preferential specifications to resolve any ambiguities occurring as a result of the coordination.

Abstract: An image forming method, comprising the steps of forming an electrostatic image on a electrostatic image-bearing member, developing the electrostatic image with toner particles having a first shape factor (SF-1) of 100 - 150 and containing a low-softening point substance to form a toner image on the electrostatic image-bearing member, transferring the toner image on the electrostatic image-bearing member to an intermediate transfer member which has been voltage-applied, transferring the toner image on the intermediate transfer member to a transfer-receiving material by a transfer means which has been voltage-applied, and heat-fixing the toner image on the transfer-receiving material. The toner particles may preferably have a second shape factor (SF-2) of 100-140. The total of SF-1 and SF-2 may preferably at most 275, particularly at most 240, for improving transfer efficiency of the toner particles. The low-softening point substance may preferably be an ester wax having a long-chain (e.g., ≧ C₁₀) alkyl group. The image forming method is effective in providing a high-quality (full-color) toner image with high transfer efficiency and free from toner sticking.

Abstract: The method involves initially involves circulation of an empty data token (T) in a ring-multicast (R-MC) system. A first subscriber (T1) adds a message (N1) to be transmitted and forwards the result to the next subscriber (T2). This subscriber copies the content of the token into a local reception buffer, adds another message (N2) and forwards the result to a third subscriber (T3) who follows a similar procedure. After a complete circuit the original message (N1) is erased by the first subscriber and replaced with fresh data (N1'). Any subscriber holding the token can add any number of messages of any length.

Abstract: An electrostatic chuck (11), which includes a plurality of ejector pins (16), means of moving up and down the ejector pins and means of grounding the ejector pins, is provided with an ejector buffer mechanism disposed between the ejector pins and the ejector pin moving means for exerting a buffer action for the tip positions of individual ejector pins. The electrostatic chuck facilitates the positioning control of the ejector pins and enables the ejector pins to come in tight contact with the wafer rear surface, and consequently the wafer can be clamped and released quickly and reliably. At the plasma processing of wafer, the ejector pins are brought to tight contact with the wafer rear surface, or a clearance within a prescribed range is created for the ejector pins from the wafer rear surface, thereby suppressing the occurrence of discharge in the gap between an ejector pin and the wafer rear surface, and consequently problems associated with the discharge can be dissolved.
