Abstract: An impedance matching film 10 includes a mixture containing indium oxide and tin oxide and being a main component of the impedance matching film, the mixture having an amorphous structure. The impedance matching film 10 for impedance matching has a Hall mobility of 5 cm2/(V·s) or more. The impedance matching film 10 has a thickness of 16 nm or more and less than 100 nm.

Abstract: A structured document search system comprises an index storage unit and a search unit. The index storage unit stores indexes caused to correspond to the nodes included in the structured documents stored in a database. The indexes include node information items about the nodes to which the indexes are caused to correspond and position information items about related nodes. The node information items include position information items about the nodes to which the indexes are caused to correspond. The search unit, when the search condition specified in the search request made by the client includes value search conditions covering the values of nodes and is a specific search condition specifying a search of a related node common to the nodes, searches the index storage unit for indexes complying with the value search conditions and acquires a position information item about a related node common to the indexes searched for.

Abstract: A structured document management system manages a structured document database. This system includes a parse processing unit which parsing a structured document to be stored in accordance with a structured document storage request made by a client, a structured document storing unit which stores parsed data obtained by parsing the structured document in the structured document database, a structured document acquiring unit which acquires parsed data corresponding to data of a structured document, which meets to a structured document acquisition request made by the client, from the structured document database, and a request processing unit which returns the parsed data acquired by the structured document acquiring unit to the client.
