20090308307 | CRUCIBLE PROTECTION SHEET AND CRUCIBLE APPARATUS USING THE CRUCIBLE PROTECTION SHEET - A crucible protection sheet is provided that can prevent damages to an inner crucible, hinder an outer crucible from silicon-carbidization, and transmit heat from the outer crucible to the inner crucible uniformly. | 12-17-2009 |
20100048073 | EXPANDED GRAPHITE SHEET, METHOD OF PROTECTING CARBONACEOUS CRUCIBLE USING THE EXPANDED GRAPHITE SHEET, AND SINGLE-CRYSTAL PULLING APPARATUS - An expanded graphite sheet with improved tensile strength is provided. By using an expanded graphite sheet with improved tensile strength as a lining for a carbonaceous crucible, a method of protecting a carbonaceous crucible is provided that reduces work hours remarkably, makes it possible to cover the inner surface of the crucible without breaking the sheet or producing gaps, and is suitable for increasing the size of the crucible, and a single-crystal pulling apparatus is also provided. An expanded graphite sheet ( | 02-25-2010 |
20100116198 | METHOD OF PROTECTING CARBONACEOUS CRUCIBLE AND SINGLE-CRYSTAL PULLING APPARATUS - A method is provided of protecting a carbonaceous crucible that is easy to handle, reduces work hour, and can cover the inner surface of a crucible without breaking the sheet and without gaps. A single-crystal pulling apparatus is also provided. The method of protecting a carbonaceous crucible by interposing a protective sheet made of an expanded graphite material between a quartz crucible and a carbonaceous crucible on which the quartz crucible is placed, including: laying two or more protective sheet pieces on an inner surface of the carbonaceous crucible, each of the protective sheet pieces having such a shape that the protective sheet pieces are combined integrally to form the protective sheet in laying the protective sheet between the crucibles. | 05-13-2010 |
20100157612 | HEAT RADIATING MEMBER, CIRCUIT BOARD USING THE HEAT RADIATING MEMBER, ELECTRONIC COMPONENT MODULE, AND METHOD OF MANUFACTURING THE ELECTRONIC COMPONENT MODULE - A circuit board using a heat radiating member that can cool an electronic component sufficiently without causing a substrate to break, increasing the total weight of the substrate, lowering the productivity, or increasing cost and device size. A circuit board has a substrate main body ( | 06-24-2010 |
20100209755 | SOLAR BATTERY UNIT - A solar battery unit is provided that can release the heat of the solar battery module sufficiently and suppress the temperature increase of a solar battery module by inhibiting the presence of an air layer with a low thermal conductivity in a heat transfer passage, whereby the energy conversion efficiency can be improved remarkably. A solar battery unit has: a solar battery module; and a heat dissipating member, provided on a back surface of the solar battery module, for releasing heat from the solar battery module. A heat transfer sheet including expanded graphite is interposed between the solar battery module and the heat dissipating member, and the heat transfer sheet is attached in a compressed state to the solar battery module and the heat dissipating member. | 08-19-2010 |
20120107222 | EXPANDED GRAPHITE SHEET - An object is to provide an expanded graphite sheet at the use stage that can prevent can prevent degradation in product quality and deterioration in product yield by inhibiting the expanded graphite sheet from containing impurities even when the expanded graphite sheet is actually used. | 05-03-2012 |
20130160703 | CARBON CRUCIBLE - A carbon crucible prevents leakage of SiO gas from a boundary portion between a straight trunk portion and a tray portion and prevents SiC formation from quickly developing. A carbon crucible ( | 06-27-2013 |
20130202872 | EXPANDED GRAPHITE SHEET AND METHOD OF MANUFACTURING SAME - An expanded graphite sheet is provided that can remarkably improve the quality and yield rate by preventing chipping and cracks in the surface in molding the sheet into a desired shape by inhibiting degradation in the flexibility while reducing the ash content to a certain degree. An expanded graphite sheet ( | 08-08-2013 |
