20120097228 | SOLAR CELL - A solar cell of the present invention comprises a p-type semiconductor layer, an n-type semiconductor layer, and a superlattice semiconductor layer interposed between the p-type semiconductor layer and the n-type semiconductor layer, wherein the superlattice semiconductor layer has a superlattice structure in which barrier layers and quantum dot layers comprising quantum dots are stacked alternately and repeatedly, and is formed so that the bandgaps of the quantum dots are gradually widened with increasing distance from a side of the p-type semiconductor layer and decreasing distance to a side of the n-type semiconductor layer. | 04-26-2012 |
20120285537 | SOLAR CELL - A solar cell comprises a p-type semiconductor layer, an n-type semiconductor layer, and a superlattice semiconductor layer interposed between the p-type semiconductor layer and the n-type semiconductor layer, wherein the superlattice semiconductor layer has a stacked structure in which quantum layers and barrier layers are stacked alternately and repeatedly, wherein the stacked structure is formed whereby a miniband is formed by a quantum level of the quantum layers on the side of a conduction band, wherein an energy level at a bottom of the miniband is lower than an energy level at a bottom of the conduction band of the barrier layers, and an energy level at a top of the miniband is higher than an energy level, which is lower than the energy level at the bottom of the conduction band of the barrier layers by an amount twice as much as thermal energy at room temperature. | 11-15-2012 |

20090065507 | Package of freeze Storage Container and Process for Producing the Same - It is demanded that packages for cryopreservation containers which can prevent the conventional cryopreservation containers stored at very low temperatures, namely −80 to −196° C., from being damaged and are excellent in heat sealability be developed. The present invention provides a package for a cryopreservation container comprising at least an adhesive fluoropolymer film. The package for a cryopreservation container according to the invention makes it possible to store blood, rare cells and vital tissues in a very low temperature environment without any damage to the container. Further, the sealing strength resulting from heat sealing after placing a cryopreservation container in the packages is very good and, therefore, liquid nitrogen can be inhibited from entering the inside and thus contamination with bacteria, viruses or the like contained in liquid nitrogen can be avoided and the package can be prevented from being broken by expansion of intruder liquid nitrogen on the occasion of thawing. | 03-12-2009 |
20100054816 | TONER FEED UNIT AND IMAGE FORMING APPARATUS EQUIPPED WITH THE SAME - A toner feed unit includes: a first feed portion having a first feed pipe for forming a first toner feed passage having a rectangular section and a first shutter member constructed so as to be rotatable about an axis perpendicular to the feed direction of the first toner feed passage and open and close the toner output end of the first toner feed passage; and a second feed portion having a second feed pipe for forming a second toner feed passage having a rectangular section and a second shutter member constructed so as to be rotatable about an axis perpendicular to the feed direction of the second toner feed passage and open and close the toner input end of the second toner feed passage. | 03-04-2010 |
20110252748 | PACKAGE OF FREEZE STORAGE CONTAINER AND PROCESS FOR PRODUCING THE SAME - A package for a cryopreservation container including at least an adhesive fluoropolymer film. The package for a cryopreservation container makes it possible to store blood, rare cells and vital tissues in a very low temperature environment without any damage to the container. Further, the sealing strength resulting from heat sealing after placing a cryopreservation container in the packages is very good. Therefore, liquid nitrogen can be inhibited from entering the inside and thus contamination with bacteria, viruses or the like contained in liquid nitrogen can be avoided and the package can be prevented from being broken by expansion of intruder liquid nitrogen on the occasion of thawing. Also disclosed is a method for packaging a cryopreservation container and a method of producing a package for a cryopreservation container. | 10-20-2011 |
20130130382 | AUTOSERUM-CONTAINING BONE MARROW CELL CULTURE SYSTEM, AUTOSERUM-CONTAINING BONE MARROW CELL CULTURE METHOD, AND METHOD FOR PRODUCING MEDICINAL COMPOSITION COMPRISING AUTOSERUM-CONTAINING CULTURED BONE MARROW CELLS AS ACTIVE INGREDIENT - To provide an autoserum-containing bone marrow cell culture system, whereby bone marrow cells, which are collected from a subject without using an anticoagulant, are subjected to an anticoagulation treatment using a medium in a liquid-tight state, cultured and then further cultured using the serum of said subject which is prepared in a liquid-tight state; an autoserum-containing bone marrow cell culture method; and a method for producing a medicinal composition which comprises, as the active ingredient, autoserum-containing cultured bone marrow cells. [Solution] An autoserum-containing bone marrow cell culture system for culturing bone marrow cells, which are collected from a subject without using an anticoagulant, using the serum of said subject, said system comprising a bone marrow cell suspension-storing device, a collected blood-storing device, an autoserum-acquiring device, and a bone marrow cell-culturing device. | 05-23-2013 |
