20090260774	SACRIFICIAL SLEEVES FOR DIE CASTING ALUMINUM ALLOYS - Some die cast aluminum alloy articles have internal cylindrical surfaces such as the round internal cylinder surfaces of a cylinder block for an internal combustion engine. During casting solidification molten aluminum alloys shrink against the metallic permanent mold tools used to mold and define such internal surfaces, and tend to stick to the tool surfaces making it difficult to remove the casting. The tendency of some aluminum casting alloys to solder to the tool can further intensify sticking. In this invention, an aluminum alloy sleeve is placed on and over the tool surface before casting and the sleeve isolates the tool from the molten aluminum. The sleeve becomes bonded to the casting and facilitates removal of the casting from the tool. The sleeve may be (and preferably is) fully machined from the internal casting surface. The sleeve may be of the same composition as the casting, in which case handling and recycling of machining chips would be facilitated. The practice of the invention is also applicable to die casting of magnesium alloys using magnesium sacrificial sleeves.	10-22-2009

20080210597	High Quality Asphalt Containing Pitch and Method of Preparing the Same - A high quality asphalt containing pitch is generated as a by-product in a solvent deasphalting process and a method of preparing the same. The pitch is obtained by subjecting a mixture comprising a first vacuum residue and a first petroleum distillate, which is lighter than the vacuum residue and has high amounts of aromatic and resin, to solvent deasphalting. The operation conditions of the solvent deasphalting process are appropriately controlled, such that aromatic and resin components contained in the atmospheric residue and vacuum residue can be distributed to the pitch, and as well, a saturate can be removed.	09-04-2008

20090030671	Machine translation method for PDF file - Disclosed is a machine translation method for a PDF file. A machine translation device extracts source language text and non-text from the input source language PDF file through image transformation, corrects the extracted source language text by using the source language text extracted from text information, restores a part that is contextually separated by the non-text from among the extracted source language text, generates a source language XML/HTML file by rearranging the extracted text and non-text so as to satisfy the contextual flow of the source language PDF file, separates source language text from a tag of the source language XML/HTML file, generates target language text by using translation knowledge and a transformation engine specified for the technical field corresponding to the source language PDF file, inserts the translated target language text other than source language text into XML/HTML file, and transforms the generated target language XML/HTML file into a target language PDF file to be output.	01-29-2009
20090043564	Method and apparatus for constructing translation knowledge - The present invention relates to a method and apparatus for constructing translation knowledge to be used in a translator. According to the invention, a source-language sentence and a target-language sentence are converted by receiving the source-language sentence and the target-language sentence corresponding to the source-language sentence and attaching a prototype, a part-of-speech, relative position information, and syntactic information in a base phrase to each morpheme of the source-language sentence and the target-language sentence. Then, word alignment and syntactic alignment are performed in the converted source-language sentence and target-language sentence, thereby extracting translation knowledge on words and syntaxes, translation knowledge on a subcategory of a bilingual inflected-word, and translation knowledge on a bilingual sentence pattern based on the results of the word and syntactic alignment.	02-12-2009
20090063128	DEVICE AND METHOD FOR INTERACTIVE MACHINE TRANSLATION - Provided are a device and method for interactive machine translation. The device includes a machine translation engine having a morphological/syntactic analyzer for analyzing morphemes and sentences of an original text and generating original text analysis information, and a translation generator for generating a translation and translation generation information on the basis of the original text analysis information, and a user interface module for displaying sentence structures of the original text and the translation, and a relationship between the original text and the translation to a user on the basis of the original text analysis information and the translation generation information, and for receiving corrections to the original text or the translation from the user. The device and method provide a user interface whereby the user can effectively recognize and correct a mistranslated part and a cause of the mistranslation, and rapidly provides a re-translated result according to the correction. Thus, it is possible to perform high-quality translation which satisfies the user.	03-05-2009
20090157380	METHOD AND APPARATUS FOR PROVIDING HYBRID AUTOMATIC TRANSLATION - The present invention provides a Korean-English hybrid automatic translation method for providing translation from Korean to English, includes: performing a morpheme analysis and a syntactic analysis on a Korean input source text; segmenting the Korean input source text into at least two source text segments, based on the results of the morpheme analysis and the syntactic analysis; and generating a PBMT (pattern-based machine translation) translated text segment and a SMT (statistical machine translation) translated text segment with respect to each of the source text segments. Further, the method includes determining, as final translation result, one of the PBMT translated text segment and the SMT translated text segment with respect to each source text segment, based on predetermined weight information; and composing the translated text segments with respect to the source text segments of the Korean input source text into one English translated text by using the determined final translation results.	06-18-2009
