20100264743STATIC 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
20100299783FUSION 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
