The reciprocating compressor includes a latching unit by which a piston is reciprocated by two times a total eccentric amount obtained by adding an eccentric amount of an eccentric portion to an eccentric amount of an eccentric sleeve in a power mode, while the piston is reciprocated by two times the eccentric amount of the eccentric portion in a saving mode, accordingly the piston can have an upper dead point same in the power mode and the saving mode, thereby reducing a dead volume between the piston and a discharge valve and increasing a variable ratio of a cooling capacity of the compressor in the saving mode. | 12-23-2010 |

20120225150 | MOLDING APPARATUS FOR SEMICONDUCTOR PACKAGE - A molding apparatus for semiconductor package includes: a lower mold supporting a first semiconductor chip; a middle mold positioned over the lower mold and supporting a second semiconductor chip, and having a first cavity for molding the first semiconductor chip on a lower surface facing the lower mold; an upper mold positioned over the middle mold and having a second cavity for molding the second semiconductor chip on a lower surface facing the middle mold; a first supply port penetrating the lower mold and connected to the first cavity; a second supply port penetrating the lower and middle molds and connected to the second cavity; and a pressure unit positioned under the lower mold and including first and second transfer rams provided respectively in the first and second supply ports to pressure molding compound therein to supply the molding compound into the first and second cavities. | 09-06-2012 |
20140220774 | METHOD OF FORMING EXTERNAL TERMINALS OF A PACKAGE AND APPARATUS FOR PERFORMING THE SAME - A method of forming external terminals of a package is provided in which a package substrate may be fixed, an edge portion of the package substrate may be supported to prevent the edge portion of the package substrate from being upwardly bent, a mask having openings may be arranged on the package substrate, and the external terminals may be supplied to the package substrate through the openings of the mask. The supporting portion may downwardly press the edge portion of the package substrate so that the edge portion of the package substrate may not be upwardly bent. As a result, the external terminals on the package substrate may have a uniform thickness. | 08-07-2014 |
