20130124152 | APPARATUS AND METHOD FOR EXPRESSING CHEMICAL COMPOUND WITH LINE NOTATION FOR DISTINGUISHING ISOMERS, AND APPARATUS AND METHOD FOR SEARCHING FOR COMPOUND USING THE SAME - Expressing a line notation for distinguishing isomers for searching a compound includes, inter alia, input unit, an atom analysis unit, an atom alignment unit, and a string production unit. An input unit receives an input file regarding three-dimensional coordinate information of each target compound atom. An atom analysis unit analyzes bond relations between the atoms based on the three-dimensional coordinate information. Bond relations corresponding to isomers are defined separately. An atom alignment unit sequentially aligns the atoms based on the preset bond relations priority, producing an array of atoms. A string production unit produces a one-dimensional string corresponding to the target compound using predefined layers to express bond relations between the atoms and the array of atoms. Stereoisomers of compounds having peptide bonds, consecutive double bonds or metals can be more distinctly distinguished, and the double bonds of the compound can be expressed using four kinds of notation. | 05-16-2013 |

20090108984 | CERAMIC COMPONENT AND METHOD OF MANUFACTURING THE SAME - Provided are a ceramic component and a method of manufacturing the ceramic component. The ceramic component includes a previously fired insulation ceramic base, a functional ceramic sheet bonded to the insulation ceramic base by a diffusion bonding layer having an anchoring structure, internal electrodes embedded into the functional ceramic sheet, and external electrodes connected to the internal electrodes. A functional ceramic paste corresponding to the functional ceramic sheet is applied to the insulation ceramic base and is dried to form a functional ceramic film. The functional ceramic film is pressed against the insulation ceramic base to anchor functional ceramic film into the insulation ceramic base for sure attachment. The functional ceramic film is fired to allow functional oxide materials included in the functional ceramic film to permeate the insulation ceramic base by solid diffusion to form the diffusion bonding layer and to change the functional ceramic film into the functional ceramic sheet. | 04-30-2009 |

20090096569 | Ceramic Component Element And Ceramic Component And Method For The Same - A ceramic component element is provided. The ceramic component element includes: an insulating ceramic base with pores formed on its surface and previously fired; and a functional ceramic sheet bonded to the insulating ceramic base and having electrical characteristics. The functional ceramic sheet is physically bonded to the insulating ceramic base by forming pressing a green sheet for the functional ceramic sheet on the insulating ceramic base at constant temperature and pressure so that parts of the green sheet are forced to put into the pores and anchored, and the functional ceramic sheet is chemically bonded to the insulating ceramic base by firing the anchored green sheet in such a manner that functional oxides of the green sheet penetrate the insulating ceramic base by solid diffusion to form a diffusion bonding layer. | 04-16-2009 |
