20090283238 | MANUFACTURING METHOD FOR OPTICAL ELEMENT - To obtain a positioning reference portion with good processing accuracy, which is formed of a newly-formed surface, a blank is press-molded by an upper mold, whereby a vertex portion abuts on an inner wall portion of a lower mold. In such a way, an oxide film that covers the vertex portion is broken by an internal pressure of the blank, and a raw material without oxide is moved by viscous flow from an inside thereof as illustrated by arrows. The raw material without oxide moved by viscous flow is thrust against the inner wall portion of the lower mold, whereby a newly-formed surface is formed, and this newly-formed surface serves as a positioning reference portion of an optical element. The newly-formed surface has surface roughness of the inner wall portion of the lower mold transferred thereto, and the positioning reference portion having good roughness is formed. | 11-19-2009 |
20090301682 | CASTING FURNACE METHOD AND APPARATUS - A system for casting comprising a mold for forming molten metal; a support for supporting the mold and transferring heat to and from the mold; and a furnace operable to substantially surround the mold through a preheat cycle, a heat cycle, and a cooling cycle. The furnace preferably moves vertically down to surround the mold for the preheat, heat, and cooling cycles and moves up and away from the mold after the cooling cycle is complete. In an alternative embodiment, the furnace may be replaced with a cooling can just before initiation of the cooling cycle. The support is preferably stationary and provides directional cooling for the mold during the cooling cycle. | 12-10-2009 |
20110042031 | Method, apparatus, computer readable storage medium and computer program for forming an object - A method for forming an object, including providing at least a first material having a melting point at a first temperature and a second material having a melting point at a second temperature; heating at least a portion of the first and second materials above the first and second temperatures to form a substantially molten alloy, the molten alloy having a solidifying point at a third temperature, the third temperature being less than the first temperature and the second temperature; and providing substantially solid further material to at least a portion of the molten alloy, the further material having a melting point at a temperature greater than the third temperature. | 02-24-2011 |
20110155341 | MOLD SET FOR MANUFACTURING CASE AND THE METHOD THEREOF - A mold set for manufacturing a case is provided. The mold set comprises an upper mold having a fluid channel; a lower mold facing the upper mold; and a drawing mold disposed between the upper mold and the lower mold, wherein the mold set has a case forming space formed among the upper mold, the lower mold and the drawing mold, and the mold set has a sharp-edge forming space communicating with the case forming space, and formed between the drawing mold and the lower mold. | 06-30-2011 |
20110180228 | CASTING METHOD AND CASTING APPARATUS - A casting apparatus has a long cooling jig inclined with respect to a vertical direction. A melt is supplied to and flowed on a bottom surface of the cooling jig, whereby a solid phase is generated in the melt to obtain a semi-solid slurry, and the semi-solid slurry is transferred into and solidified in a cavity of a mold to obtain a casting. The casting apparatus further has a release agent application unit, and a release agent is applied by the application unit to the bottom surface of the cooling jig in a direction toward a supply of the melt at an angle of less than 90° to the bottom surface before supplying the melt to the cooling jig. | 07-28-2011 |
20120227923 | Method, Apparatus, Computer Readable Storage Medium and Computer Program for Forming an Object - A method for forming an object, including providing at least a first material having a melting point at a first temperature and a second material having a melting point at a second temperature; heating at least a portion of the first and second materials above the first and second temperatures to form a substantially molten alloy, the molten alloy having a solidifying point at a third temperature, the third temperature being less than the first temperature and the second temperature; and providing substantially solid further material to at least a portion of the molten alloy, the further material having a melting point at a temperature greater than the third temperature. | 09-13-2012 |
