摘要:
A document storage stores a plurality of documents belonging to a certain field. The administrator of a host device uses a classification attribute selector to select the types of attributes suitable for classifying the documents stored in the document storage, from the types of attributes which are stored in a candidate storage and can be used as classification keys, and stores the selected types of attributes in a classification attribute storage. An attribute analyzer analyzes each of documents retrieved by a document retriever to determine which one of the types of attributes stored in the classification attribute storage an attribute element contained in the document belongs to. An attribute classifier classifies each of the retrieved documents into a category according to the type of the attribute element contained in the document based on the determined type of an attribute from the attribute analyzer.
摘要:
The present invention discloses a semiconductor device and its manufacture by which damages, such as cracks, generated by the heat of melting of a fuse that is employed for isolating a circuit from the other circuits, can be blocked from propagating into other parts of the semiconductor device. A lower protective film formed on an oxide film provided on a substrate, has a width larger than that of the fuse, and blocks the propagation of damages generated at melting of the fuse. A first insulating film formed on the oxide film so as to cover the lower protective film, has two grooves reaching the lower protective film that is formed so as to surround the fuse. The fuse is formed in the region between the two grooves formed in the first insulating film. A second insulating film is formed on the first insulating film so as to cover the fuse, and has grooves connected to the grooves formed in the first insulating film. A side-face protective film is formed within the grooves formed in the first and second insulating films and blocks the propagation of damages generated at melting of the fuse.
摘要:
A heat-laminatable composite film obtained by providing, in sequence, a layer of a mixture of (B) a reactive polyurethane containing isocyanate groups therein and (C) a vinyl chloride-vinyl acetate copolymer on one surface of a film of (A) a saponified product of ethylene-vinyl acetate copolymer, or, Layer (B) and further Layer (C) on one surface of the film of (A). A laminated material obtained by heat-laminating the composite film onto at least one surface of a plasticized polyvinyl chloride layer.The heat-laminatable composite film of the present invention is excellent in blocking resistance and adhesive strength. Further by heat-laminating the composite film onto the plasticized polyvinyl chloride layer, bleeding of the plasticizer in the polyvinyl chloride layer can be prevented.
摘要:
A magnetic recording/reproducing apparatus for sequentially recording each of four pilot signals of different frequencies on each video track to be multiplexed with a video signal and reproducing the video signal and the pilot signals at which time the pilot signals are separated from the video signal and used as a tracking signal to control the transport speed of the magnetic tape, wherein upon reproduction the levels of the pilot signals reproduced from the right and left adjacent video tracks are detected and one of the reproduced pilot signals from the right and left adjacent tracks is controlled in its level so that the tape travelling speed is controlled to make the center of the video head scan the same position on the track as upon recording.

The invention provides a method of continuously copolymerizing ethylene and vinyl acetate in a solvent in the presence of a radical initiator without causing gel formation.
摘要:
A saponified ethylene-vinyl acetate copolymer composition, improved in behavior in the molten state, which comprises: a saponified ethylene-vinyl acetate copolymer, with an ethylene content of 20-80 mole percent and a saponification degree of at least 85 percent, and 0.00005 to 0.005 percent by weight, based on said copolymer, of manganese, copper or mixtures thereof; said composition, when extracted with pure water, giving an acidic extract, is disclosed, along with a method of making the same.
摘要:
A high frequency energy apparatus is provided in which high frequency energy is supplied into a heating chamber containing an object to be heated for heating the same. A temperature sensor unit senses either the temperature of air within the heating chamber or the temperature of air flowing out of the heating chamber and a memory unit memorizes a sensed air temperature. When a difference between the air temperature sensed and the memorized temperature reaches a preset value, the amount of supply of the high frequency energy is varied. The preset value is varied with the heating time for heating the object more properly.
摘要:
A high frequency energy apparatus for heating an object contained in a heating chamber by high frequency energy which is supplied to the chamber. The temperature of the air in the heating chamber or flowing out thereof is detected. When the temperature of the air reaches a predetermined level, the high frequency energy is controlled. The predetermined level is also changed with the heating time.
