  • Patent number: 7254269
    Abstract: In the prior art, in character recognition of a language having many characters, such as Japanese, a feature vector is extracted from an input pattern, distances between the feature vector and reference vectors are calculated, and a character corresponding to a reference vector having the smallest distance value is selected as a recognized character. However, in the character recognition of a language having many characters, since the number of the reference vectors to be compared is large, there is a limit in improvement of processing speed of the character recognition. In the present invention, reference vectors corresponding to target characters are classified into plurality of classes based on occurrence frequencies of characters. When distances between the feature vector and the reference vectors are calculated, a comparison is sequentially made from the reference vectors of a class having a high character occurrence frequency, so that the processing speed of the character recognition is improved.

  • Publication number: 20070106767
    Abstract: There is provided a database server capable of easily adding various kinds of associated data without modifying the structure of the database. A heading node (T node) is correlated with an associated node (A node) and an association role R is defined between the T node and the A node associated with it. Furthermore, each of the T node and the A node is added with an identifier (ID), its attribute (node type), and a name (node name). The data having such a structure is stored in an association/role table (AR table) composed of an entry containing ID of the A node and T node associated with each other and the association role R defined between them and in an identifier table (ID table) containing the ID, attribute, and name of the A node and the T node, so that the data can be searched.

  • Patent number: 7113897
    Abstract: The invention provides a text segmentation apparatus comprising means for analyzing an electronic text to determine likelihood of segmentation point for each of sentence ends in the text based on a coherent unit and means for segmenting the text into text segments based on the likelihood of segmentation point. The apparatus is programmed to segment the text segment at the position having the best likelihood of segmentation point within the text segment when the size of any of the segmented text segments exceeds a threshold value to be determined based on the specified text segmentation size. Particularly, the apparatus determines the similarity between the text parts contained in a pair of windows to be set up on the left and right sides of each sentence end position in the text so as to obtain similarity curves. Then, the apparatus determines the likelihood of segmentation point for each sentence end point based on the obtained similarity curves.

  • Publication number: 20060131983
    Abstract: In a commutator of a rotary electric machine, each of commutator segments has a low-resistive layer made of a low-resistive material and a high-resistive layer made of a high-resistive material having a specific resistance higher than that of the low-resistive material. The low-resistive material contains a carbonic material and a binder. The high-resistive material contains a carbonic material, a binder and an inorganic substance such as boron nitride. A mixing ratio of the inorganic material to the high-resistive material is more than 20 wt %. Alternatively, a brush, which makes contact with the commutator segments, can have the high-resistive layer and the low-resistive layer.

  • Publication number: 20050149846
    Abstract: A document is classified by document style on the basis of textual analysis without depending upon morphological analysis. A style-specific frozen pattern is prepared as a reference dictionary for each document style. A frozen pattern list is extracted for an input document based on the basis of a state of appearance of a style-specific frozen pattern present in the document. Confidence for each document style is calculated based on the frozen pattern list and the detected style of the input document.

  • Patent number: 5923429
    Abstract: A film deposition apparatus and a method thereof for accurately forming a film of a given thickness on the surface of a wafer is described. The film deposition apparatus includes a laser beam to perform a precise in-situ monitoring of a change in thickness of the film being deposited on the surface of the wafer. An optical guide is provided in an attachment coupled to the quartz furnace of a chemical vapor deposition apparatus. A laser beam is introduced into the quartz furnace through the optical guide, and is projected onto the wafer. The laser beam reflected by the wafer is channeled through the same optical guide to be discharged to the outside of the quartz furnace. A change in thickness of the film is monitored based on the strength of the reflected laser beam.
