Abstract: In a method of forming a silicon oxide film, a target substrate that has a silicon layer on a surface is loaded into a process area within a reaction container, while setting the process area to have a loading temperature of 400° C. or less. Then, the process area that accommodates the target substrate is heated, from the loading temperature to a process temperature of 650° C. or more. Water vapor is supplied into the reaction container during said heating the process area, while setting the water vapor to have a first concentration in an atmosphere of the process area, and setting the process area to have a first reduced pressure. After said heating the process area to the process temperature, an oxidation gas is supplied into the reaction container, thereby oxidizing the silicon layer to form a silicon oxide film.

Abstract: An image sensing apparatus capable of separately performing image processing on odd-numbered fields and even-numbered fields for each of the image data from the left lens and right lens when a 3-D (stereoscopic) compatible lens is mounted, and when a normal lens is mounted, recording image data while correlating fields and reducing redundant data. When 3-D compatible lens 1 is mounted to image sensing apparatus main body 12, the mounting of the lens is informed to the image sensing apparatus main body 12. In response, the image sensing apparatus main body 12 performs image processing separately on the left and right images for each field. For instance, the image compression mode is switched from an every-field structure to an alternate-field structure.

Abstract: Disclosed is a keyword extraction apparatus and method capable of overcoming a problem in the conventional automatic keyword extraction wherein character strings in a sentence to be processed are employed, as they are, to assign a document with an index in terms of keywords; hence words having the similar meaning but different expressions in written language cannot be retrieved. The keyword extraction apparatus comprises technical term storage means for storing technical terms with proper expressions and different expressions thereof, and basic word storage means for storing general basic words of high frequency. Technical-term segmentation point setting means cuts out a range of any of the technical terms stored in technical term storage means from an input sentence. When the cut-out technical term is written in a different expression, the different expression is replaced by a corresponding proper expression in proper expression replacing means.

Abstract: The database information retrieval system includes a parser for parsing a natural language input query into constituent phrases with a analysis of the syntax of the phrase. The parser may make use of tables and or dictionaries to aid in terminology identification and grammatical syntax analysis. The system also includes virtual tables for converting phrases from the natural language query into retrieval keys that are possessed by the database. The virtual tables account for particles or terms that modify the phrases in the natural language query. A collating unit is provided in the system for preparing a query or retrieval formula executable in the database from the retrieval keys provided by a virtual table the collating unit selects. Lastly, the system contains a retrieval execution unit for retrieving data from the database on the basis of the database retrieval formula produced by the collating unit.
