| 20110133627 | Color electronic paper display device and method for manufacturing the same - The present invention provides a color electronic paper display device, which includes: a base; a first colorant disposed on the base; a second colorant disposed on the base, the second colorant having lower reflectance and size lower than those of the first colorant; and an electrode part for applying voltages to the first and second colorants. | 06-09-2011 |
| 20110065229 | Method of manufacturing back-surface electrode type solar cell - There is provided a method of manufacturing a back-surface electrode type solar cell. The method may include: forming a conductive metal thin film on a crystalline silicon wafer; forming plate-resistant partition walls on a top surface of the conductive metal thin film; forming a metal layer in a space between the plate-resistant partition walls and then removing the plate-resistant partition walls; and removing the conductive metal thin film that is exposed by removing the plate-resistant partition walls so as to expose the crystalline silicon wafer. | 03-17-2011 |
| 20090114434 | METHOD OF MANUFACTURING NON-SHRINKAGE CERAMIC SUBSTRATE AND NON-SHRINKAGE CERAMIC SUBSTRATE USING THE SAME - There is provided a method of manufacturing a non-shrinkage ceramic substrate, and a non-shrinkage ceramic substrate using the same. A method of manufacturing a non-shrinkage ceramic substrate by firing a ceramic laminate including an internal electrode circuit pattern according to an aspect of the invention may include: laminating at least one constraining ceramic sheet on each of the upper and lower surfaces of the ceramic laminate to form constraining layers; performing a primary firing process on the ceramic laminate having the constraining layers thereon; polishing the surface of the ceramic laminate from which the constraining layers are removed; forming ceramic paste on the polished surface of the ceramic laminate while exposing connection terminals of the internal electrode circuit pattern to the outside environment through openings in the ceramic paste; forming a surface electrode on the surface of the ceramic paste by patterning so that the surface electrode is electrically connected to the connection terminals; and performing a secondary firing process so that the surface electrode adheres to the ceramic paste. | 05-07-2009 |
| 20090066425 | FREQUENCY SYNTHESIZER HAVING MULTI-BAND VOLTAGE CONTROLLED OSCILLATOR - There is provided a frequency synthesizer including a multi-band voltage controlled oscillator having a plurality of voltage controlled oscillating cores outputting oscillation frequencies having different bands according to an input control voltage. Each of the voltage controlled oscillating cores outputs a frequency band divided into a plurality of bands, and the voltage controlled oscillating core operates by each of the divided bands, and one of the voltage controlled oscillating cores operates in one of the bands according to the control voltage. The frequency synthesizer further includes a comparator unit and an oscillation band-determining unit. The comparator unit compares the control voltage with a pre-set reference voltage range. The oscillation band-determining unit changes the band where the voltage controlled oscillating core operates into another one of the bands when the control voltage is out of the pre-set reference voltage range. | 03-12-2009 |
