20100264743 | STATIC TRANSFER SWITCH DEVICE, POWER SUPPLY APPARATUS USING THE SWITCH DEVICE AND SWITCHING METHOD THEREOF - Disclosed is a static transfer switch with a modified structure that can selectively supply power from power sources to a load stably and continuously, a power supplying apparatus employing the same, and a switching method thereof. The present invention includes mechanical/electrical contact point switches in parallel to semiconductor switches, and minimizes operation time of the semiconductor switches by turning on/off the mechanical or electrical contact point switches together when the semiconductor switches are turned on/off to reduce a failure rate of the semiconductor switch. Also, the static transfer switch makes a switching unit electrically/mechanically separable from a power source with failure to switch a power supply path and thereby prevent superposition caused by the switching unit. This prevents a problem caused when electrical or mechanical contact point switches simply in parallel, that is, a problem that power sources are turned on simultaneously when the power supply paths are switched. | 10-21-2010 |
20100299783 | FUSION POLYNUCLEOTIDE FOR BIOSYNTHESIS OF BETA-CAROTENE USING BICISTRONIC GENE EXPRESSION AND METHOD FOR PRODUCING BETA-CAROTENE USING THE SAME - The present invention relates to fusion polynucleotides for biosynthesis of beta-carotene and a method for producing beta-carotene using the same. More particularly, it relates to fusion polynucleotides encoding phytoene synthase, connective sequences of FMDV-derived 2A sequence or internal ribosome entry site (IRES) and carotene desaturase, and a method for producing beta-carotenes using the same. Fusion polynucleotides and the recombinant vector using the same of the present invention have the effect of expression both phytoene synthase gene and carotene desaturase gene stably within cell transformants. Accordingly, fusion polynucleotides of the present invention can be used to regulate the biosynthetic metabolism of plant producing beta-carotene. Furthermore, it can be applied to effectively increase the content of beta-carotene, a useful metabolite. | 11-25-2010 |

20140377453 | Insulating Adhesive Composition for Metal-Based Copper Clad Laminate (MCCL), Coated Metal Plate Using Same, and Method for Manufacturing Same - The present invention relates to an insulating adhesive composition for metal printed circuit board, an adhesive-coated metal plate using the same, and a method for manufacturing the adhesive-coated metal plate. The adhesive composition according to the present invention forms an adhesive layer that is excellent in terms of adhesion to a copper foil, electrical insulating properties, and thermal resistance. The composition contains a specific epoxy resin, a curing agent and alumina. According to the present invention, in coating the metal plate with the solvent type adhesive, a roll coating method is used to perform a continuous coating process on the metal plate, thereby improving productivity when compared to the general method using a sheet type adhesive film. | 12-25-2014 |
