    摘要: In a novel approach for retrieving information a set of sub-documents first is established based upon a set of documents. A query is processed which operates on the set of sub-documents, causing a score to be generated for each sub-document. The score for each sub-document is indicative of the relevance of the corresponding sub-document to the query. The scores are reviewed and the best sub-document is retrieved. According to one aspect of the invention, the best sub-document has a score that indicates the highest relevance between the sub-document and the query. According to another aspect of the invention, in response to a user selection, the next best sub-document is identified and retrieved. The sub-documents are also presented to the user in an order based upon the scores. According to another aspect of the invention, the document containing the sub-document having the best score is displayed and automatically scrolled to the location of the sub-document having the best score. Based upon user input, the document is automatically scrolled to the location containing the next best sub-document. If the next best sub-document is contained in another document, that document is automatically loaded.

    摘要: An electrochemical capacitor is disclosed that features two, separated, high surface area carbon cloth electrodes sandwiched between two current collectors fabricated of a conductive polymer having a flow temperature greater than 130.degree. C., the perimeter of the electrochemical capacitor being sealed with a high temperature gasket to form a single cell device. The gasket material is a thermoplastic stable at temperatures greater than 100.degree. C., preferably a polyester or a polyurethane, and having a reflow temperature above 130.degree. C. but below the softening temperature of the current collector material. The capacitor packaging has good mechanical integrity over a wide temperature range, contributes little to the device equivalent series resistance (ESR), and is stable at high potentials. In addition, the packaging is designed to be easily manufacturable by assembly line methods. The individual cells can be stacked in parallel or series configuration to reach the desired device voltage and capacitance.

    摘要: The present invention is a method and apparatus for retrieving information from a database. Initially, the documents within the database are divided into mutually exclusive subdocuments that generally correspond to paragraphs of text. The present invention further creates a second set of subdocuments that overlap adjacent paragraphs of text. In particular, the location of the overlapping subdocuments depends on the size of the initial paragraphs. This second set of overlapping subdocuments are scored just as the mutually exclusive subdocuments are scored. The scores from both the mutually exclusive and overlapping subdocuments are used in ranking the relevance of documents to a query. The use of both sets of subdocument scores improves the effectiveness of the scoring algorithm.

    摘要: A method of making an electrical contact to a metal on which an electrically insulating native oxide is formed includes applying atoms or ions to the native oxide, heating the metal and oxide to a temperature and for a time effective to make the oxide, where the atoms and/or ions have been applied, electrically conducting and in electrical communication with the metal. The invention may be employed to establish electrical contacts with native oxides on aluminum, molybdenum, niobium, tantalum, titanium, tungsten, and zirconium. The atoms and ions include aluminum, antimony, arsenic, boron, gallium, indium, phosphorus, and silicon. An aqueous solution of boric acid and trisodium phosphate may be applied to establish electrically conductive regions in an oxide on niobium, tantalum, titanium, and stainless steel after heat treatment. Brushing with palladium wires mechanically applies palladium atoms to tantalum oxide to establish electrical contact to the tantalum after heat treatment. The invention is useful in forming containers for electrolytic tantalum capacitors and making direct metal-to-metal electrical connections for capacitors and contacts for switches and relays.

    摘要: A package for an electrical component that generates a gas during operation includes a selectively permeable body that allows the gas generated within the package to escape while preventing the escape of desired fluids from the package and the entrance of undesired fluids into the package. In a double layer capacitor according to the invention, the body may be a polymeric material, such as silicone rubber or polypropylene, through which carbon dioxide permeates relatively rapidly but through which water vapor permeates relatively slowly. A package including a container and an attached cover includes a resilient member disposed adjacent the periphery of the cover for dissipating forces that might be applied to an electrically insulating seal in the cover through which an electrical terminal passes.

    摘要: A tippling installation for the discharge of bulk goods from large barges comprises a dry basin in which a trough-shaped cradle can have its ends sealed against opposite end walls of the basin in which there are lock gates. The cradle provides a holding vessel into which the barges are floated through the lock gates. After closing the gates and draining the cradle, the barge is tipped by rolling the cradle sideways along guide and support tracks which provide positive location while the barge is held clamped in the cradle. The contents of the barge are discharged into a receiving space from which any liquid is drained to separate it from the discharged solids that are then collected. The arrangement is able to prevent pollution of the waterway by the escape of any of the barge contents during discharge. Because they roll on fixed supports relatively little lifting efforts needs to be expanded and very large barges can be handled.
