Abstract: A method and apparatus for automatically accessing a WWW page is provided for realizing a function of automatically jumping to a desired page to automatically download desired data in spite of intervening pages which require a user to enter information, and a function of dealing with a change in configuration of an accessed page. In a web browser, a list structure is created for each displayed window, and all nodes under HTML displayed in a window corresponding to the list structure are copied and stored as node information. Further, when an event occurs with respect to an arbitrary node within a window, an address and event type of the node are recorded in the stored node information corresponding to the node. The record is comprised of a sequence of records of an event occurrence address and event type by using URL and window identifier as keys.

Abstract: A method and an apparatus for processing documents expressed in terms of the graph based on the graph theory. Grouped constituent description series as the contents of a predescribed document are stored in a constituent description series retaining section. A first identifier acquisition section acquires an identifier series corresponding to the constituent satisfying a designated first condition from the grouped constituent description series that are retained in the constituent description series retaining section. The acquired identifier series is stored in an identifier series retaining section. A second identifier acquisition section acquires the identifier series satisfying a designated second condition from the identifier series that are retained in the identifier series retaining section. The acquired identifier series is stored in the identifier series retaining section in a state that it can be distinguished from other constituent description series already retained therein.

Abstract: According to the present invention, a document structure generation system in which logical structure generation rules are established between a logical structure satisfying the restrictions of a generic logical structure which restricts the logical structure of an input document or documents and a logical structure satisfying the restrictions of a generic logical structure which restricts the logical structure of an output document or documents. A logical structure of an output document can be automatically generated from a logical structure of an input document according to the rules.

Abstract: A way and a system for invoking a method in an object-oriented language which is so arranged that when a predetermined method for a first whole object is invoked, two instance variables of the first whole object maintain an exclusive relationship while the exclusive relationship is also satisfied between first and second part objects. In such an arrangement, when a message is sent from a second whole object to the first part object and the exclusive relationship cannot be satisfied between the first and second part objects, a daemon method for the first whole object is invoked to send a message from the first whole object to the second part object, thereby maintaining the exclusive relationship between the first and second part objects.

Abstract: A tubular lining material and a method and apparatus for manufacturing same, the tubular lining material being suitable for reinforcing pipe lines and comprising a tubular textile jacket having on the external surface thereof a coating of plural synthetic resins in the form of laminated layers, characterized in that the outermost layer of the coating is composed exclusively or predominantly of a thermoplastic polyester elastic resin and the innermost layer of the coating is composed exclusively or predominantly of a thermoplastic polyurethane elastic resin, the coating having been bonded superificially onto the external surface of the tubular textile jacket. The tubular lining material is manufactured by simultaneously extruding plural synthetic resins in an annularly layered form superficially onto the external surface of the tubular textile jacket, using an apparatus provided with an annularly arranged multiple extruders.

Abstract: A lining material utilizable for a pipe-lining method, which comprises a tubular textile jacket woven or knitted with synthetic fiber yarns provided on the exterior surface thereof with a laminated two or three layer film of the following resinous materials:(1) in case of two layers:the outer layer: a synthetic resin of polyolefin series having a stress-crack resisting property of at least 1000 hours the inner layer: (1) a resin wherein an ethylenically unsaturated carboxylic acid has been grafted to an ethylene-vinyl acetate copolymer or (2) a resin comprised of 30-70% of a resin wherein an ethylenically unsaturated carboxylic acid has been grafted to a polymer of an .alpha.-olefin and 70-30% of a styrene-ethylene butylene-styrene resin composition.(2) in case of three layers:between the above described outer layer and inner layer is interposed an intermediate layer of the following resinous material: the intermediate layer: a styrene-ethylene butylene-styrene resin composition.

Abstract: A tubular lining material for city water pipe lines, which comprises a tubular textile jacket made of warps and a weft woven in a tubular form overlaid with a fluid-impervious coat of a flexible synthetic resin, at least one of the warps and the weft being comprised of threads manufactured by intertwisting filament yarns with spun yarns and/or spun-like textured yarns of synthetic fibers, and the flexible synthetic resin comprising a blend of 60-40% by weight of a polyethylene resin and 40-60% by weight of a styrene-ethylene-butylene-styrene resin, having a stress-crack resisting property of at least 1000 hours which penetrates the interstices of the fabric structure of the tubular textile jacket. The tubular lining material is remarkably improved in flexibility, heat-resistance, abrasion-resistance, stress-crack resistance and other mechanical strength properties and is harmless to drinking water.

Abstract: In the manufacture of hose, a tubular textile is passed through one or more coating liquids, such as rubber or synthetic resin. An expander means, having a plurality of panels disposed radially about a shaft element so as to form a generally annular surface, and adapted to be centrifugally or centripetally movable by means of a spring mechanism mounted on said shaft, is disposed seriatim with the coating baths and are located within the tubular textile whereby to expand the coated tube during passage through drier means. Annular doctor means are disposed in operative association with said expander means and externally of said coated tube.
