  • Patent number: 6739508
    Abstract: A control section is used which executes the following steps. That is, a) making a plurality of voters respectively vote evaluation of voting-object information in accordance with an on-line voting system by using a plurality of clients, each client being set at a voters sides, b) calculating average evaluation in accordance with voting results, c) deciding a voter's rank of each of the voters in accordance with a deviation between average evaluation and evaluation by the voter concerned, and d) determining overall evaluation of voting-object information at least in accordance with a result of weighting a voting result correspondingly to the voter's rank.

  • Publication number: 20030211721
    Abstract: A plurality of metal wire layers consisting of a first metal wire layer and a second metal wire layer are formed on a semiconductor substrate. A fluorinated silicate glass film serving as an interlayer metal dielectric film is formed between the first and second metal wire layers. A silicon nitride film serving as a protective insulation film is formed on the fluorinated silicate glass film layer. An adhesive layer made of, for example, a P—SiO film, P—SiON film, or PE-SiO film, is formed between the fluorinated silicate glass film and the silicon nitride film.

  • Publication number: 20020138250
    Abstract: An interface unit issues input/output instructions regarding an input of a translation target sentence, an output of a translated sentence, and a translation control. A machine translating apparatus translates a document in a certain language into a document in another language. A translation memory device translates a sentence by searching an original/translation database in which sentences in a certain language and original/translation sentences in another language corresponding thereto have been accumulated. A data compatible processing unit makes original/translation information translated by the machine translating apparatus and original/translation information translated by the translation memory device common, thereby enabling them to be fetched mutually as original/translation information.

  • Publication number: 20020090809
    Abstract: An interconnection is formed on a semiconductor substrate having a semiconductor element formed thereon. Next, a passivation film is formed on the semiconductor substrate including the interconnection. Further, a polyimide film, which is served as a buffer coating film, is formed on the passivation film. Further, the polyimide film is patterned. Next, the passivation film is subject to etching while the patterned polyimide film is taken as a mask. Next, a hardened layer, which is formed on the surface of the polyimide film as a result of etching, is removed through ashing process. Next, the semiconductor substrate after ashing process is cured so as to transform the polyimide film into imide.

  • Patent number: 6226638
    Abstract: An information searching apparatus converts an input key-term into key-terms for searching the database by at least two times of expansions using a related-term dictionary and a translation dictionary, and stores the history of the expansions in the form of a tree structure. Then, a part or the whole of the thus-stored tree structure is displayed on a screen. A searcher designates appropriate terms among the thus-displayed information as key-terms for searching.
