  • Patent number: 11298739
    Abstract: Provided is a method for manufacturing an iron core that enables reduction of variations in dimension of a plurality of metal plates that occur during pressing of the laminate of these metal plates. The method includes: a laminate preparation step of stacking a plurality of metal plates to prepare a laminate; a pressing step of giving a temperature gradient to the laminate and pressing the laminate with a pressing machine having a punch and a die; and a temperature-gradient removal step of removing the temperature gradient from the laminate. The pressing step gives the temperature gradient to the laminate so that the temperature rises from the punch-side to the die-side in the stacking direction of the laminate.

  • Patent number: 7672829
    Abstract: A method and system for translating text from a source language into a target language is described. A source word table and a source structure analysis table corresponding to the source language can be generated based on the text to be translated. A target word table and a target structure analysis table corresponding to the target language can be generated based on the source word table and the source structure analysis table. A translation of the text from the source language into the target language is then generated using the target word table and the target structure analysis table.

  • Patent number: 7475009
    Abstract: Methods and apparatus, including computer program products, featuring techniques for text input support that, among other capabilities, can automatically convert a string of characters lacking spaces into a sentence that includes spaces. The apparatus and methods may find applicability, for example, when an operator inputs characters sequentially for generating text composed of plural words separated from each other with spaces, like English or French text.

  • Patent number: 7466267
    Abstract: An antenna device includes a dielectric substrate, a ground plane, a pair of antenna elements, a feeding section, and a pair of transmission lines. The ground plane is formed on a surface of the dielectric substrate. The antenna elements are flat, have different resonant frequencies, are formed on another surface of the dielectric substrate, and respectively have ends electrically connected to the ground plane. The feeding section feeds power to each of the antenna elements. The transmission lines carry out impedance conversion such that parts of the transmission lines which are connected to the antenna elements have impedances matching input impedances of the antenna elements, respectively, and such that part of the feeding section which is fed with the power has an impedance matching an impedance of the feeding section.

  • Publication number: 20040268245
    Abstract: It provides the system which analyzes a language correctly. It divides a given sentence into the token and it fixes a part of speech. As for the token which can not be fixed as one part of speech, it decides by the part of speech of back and forth the token. As for the predicate, it analyzes an attribute using suffix and so on. Next, it corresponds in the role and the part of speech. Then, it does the analysis of the local structure and the decision of the role. After that, it analyzes the whole structure by the extraction of the subordinate sentence and the sentence pattern analysis and so on. By the analysis of the whole structure, it corrects if it is necessay to correct local structure.
