20120153526 | METHOD AND DEVICE FOR MANUFACTURING ARTIFICIAL STONE - The present invention relates to a method and device for manufacturing artificial stone. More specifically, the method includes the steps of: (a) mixing two or more kinds of chips having different grain sizes with a raw material for artificial stone; (b) injecting the raw material for artificial stone mixed with the chips into a mold; (c) applying primary vibration using a vibration device such that the raw material is uniformly dispersed in the mold; (d) applying vacuum to eliminate bubbles in the raw material; and (e) molding artificial stone by applying a secondary vibration using the vibration device. According to the method and device for manufacturing artificial stone of the present invention, the deposition rate of chips exposed at a surface of artificial stone is maximized, and thus the external appearance of artificial stone can be more naturally expressed and resistance against abrasion and staining can be improved. | 06-21-2012 |
20140370225 | FLOORING MATERIAL USING POLY LACTIC ACID RESIN AND CONSTRUCTION METHODS OF THE SAME - Disclosed is a flooring material in which edge portions of a base layer and a surface layer of the flooring material are formed to be rounded when press forming the base layer and the surface layer, thereby providing its fine appearance, and which can provide construction joints between tiles through a dry construction method using an adhesive. The flooring material formed of a PLA resin, which is constructed on floor, includes a resin tile having a base layer and a surface layer which is stacked on the base layer and which consists of a dimensionally stabilizing layer, a balance layer, a printed layer, a transparent layer and a protective layer, the base layer and the surface layer being formed of the PLA resin and each four edge portion thereof being formed into a curved surface; and a construction joint which is formed at a gap formed between the tiles, wherein an adhesive is applied on the floor before the tile is attached, and the tiles are arranged to be spaced apart from each other with a desired gap therebetween, and the construction joint is formed at the gap. | 12-18-2014 |

20100041298 | ORGANIC ELECTROLUMINESCENT DEVICE AND METHOD OF MANUFACTURING THE SAME - An organic electroluminescent device and its method of manufacturing are provided. The organic electroluminescent device may include a rear substrate, an organic electroluminescent unit including a first electrode, an organic film, and a second electrode stacked on a surface of the rear substrate. It may also include a front substrate joined to the rear substrate to seal an internal space in which the organic electroluminescent unit is disposed. It may also include a porous oxide layer composed of a porous silica and a metal compound on a lower surface thereof. A device constructed according to the present invention may have excellent adsorption of moisture and oxygen, thereby increasing the life span of the device. | 02-18-2010 |
20100264815 | ORGANIC ELECTROLUMINESCENCE DEVICE AND MANUFACTURING METHOD THEREOF - An organic electroluminescence (EL) device which has a rear substrate, an organic EL element formed on the rear substrate and having a laminate structure in which a first electrode, an organic layer and a second electrode are sequentially laminated, a front substrate coupled to the rear substrate via sealant to seal an internal space in which the organic EL element is accommodated, and a transparent nanoporous oxide layer having nanoporous oxide particles disposed in the internal space formed by the rear substrate and the front substrate. Since the organic electroluminescence device includes the transparent nanoporous oxide layer having the nanoporous oxide particles and pores, it has an improved lifetime by increased moisture and oxygen absorbing properties. | 10-21-2010 |
