| 20100051172 | METHOD FOR MANUFACTURING CERAMIC GREEN SHEET AND METHOD FOR MANUFACTURING MULTILAYER CERAMIC CIRCUIT BOARD - A method for manufacturing a ceramic green sheet includes providing a stamp having an imprinting surface on which a raised structure corresponding to a circuit pattern is formed, imprinting the stamp on the ceramic green sheet to form a depressed pattern in the ceramic green sheet, the depressed pattern being transferred from the raised structure, curing the ceramic green sheet with the stamp imprinted on the ceramic green sheet, separating the stamp from the ceramic green sheet, and providing the depressed pattern of the ceramic green sheet with the conductive material. | 03-04-2010 |
| 20100051173 | MANUFACTURING METHOD OF MULTI-LAYER CERAMIC SUBSTRATE - There is provided a method of manufacturing a multilayer ceramic substrate, the method including: providing a non-sintered multilayer ceramic substrate having a plurality of low temperature sintering green sheets laminated therein; disposing a hard-to-sinter constraining green sheet on at least one of top and bottom surfaces of the non-sintered multilayer ceramic substrate; sintering the non-sintered multilayer ceramic substrate having the hard-to-sinter constraining layer disposed thereon; immersing the sintered multilayer ceramic substrate into an acidic solution; and activating a contact between the hard-to-sinter constraining layer and the acidic solution such that the hard-to-sinter constraining layer is removed. | 03-04-2010 |
| 20100059266 | CERAMIC MULTI-LAYER CIRCUIT SUBSTRATE AND MANUFACTURING METHOD THEREOF - Provided is a method of manufacturing a ceramic multi-layer circuit substrate. A plurality of ceramic blocks, in each of which one or more ceramic green sheets having via-electrodes are layered one atop the other, are formed and are then fired. The fired ceramic blocks are aligned with each other. One or more bonding green sheets each having bonding electrodes in positions corresponding to the via-electrodes of the ceramic blocks are prepared. Each of the bonding green sheets is interposed between a pair of the ceramic blocks opposing each other. The ceramic blocks and the bonding green sheets are bonded and are then fired. | 03-11-2010 |

| 20100098294 | METHOD AND APPARATUS FOR DETECTING LANE - A method and an apparatus for detecting a lane are disclosed. The lane detecting apparatus includes: a region of ID setup setting a region of ID including a road region of a current lane in an acquired image; a road sign verifier verifying existence of a road sign within the set region of ID; an ROI setup calculating a difference value between a lane prediction result and previous lane information when there exists a road sign and setting an ROI based on the calculated difference value; and a lane detector detecting a lane by extracting lane markings based on the set ROI. Accordingly, a lane can be more accurately detected even in a road environment including a road sign by removing the road sign to extract only necessary lane markings. | 04-22-2010 |
