Abstract: The present invention relates to a fuel rod of a nuclear fuel assembly having a vase-like compression spring adapted to increase the internal volume thereof wherein when the vase-like compression spring is inserted into a cladding tube, it has a relatively smaller volume occupied inside the fuel rod when compared with the existing coil type compression spring, such that the vase-like compression spring can ensure a sufficient space portion receiving the fission gases generated during the operation of the fuel rod, thereby increasing the burn-up performance of the fuel rod and the mechanical integrity thereof.

Abstract: Disclosed is a method for the mass production of a monomeric or dimeric immunoglobulin Fc region, free of initial methionine residues, using a recombinant expression vector comprising a nucleotide sequence coding for a recombinant immunoglobulin Fc region comprising an immunoglobulin Fc region linked at the N-terminus thereof to an immunoglobulin Fc region via a peptide bond.

Abstract: The present invention relates to a non-contact type battery pack charging apparatus using a magnetic field. In the non-contact type battery pack charging apparatus of the present invention, a main control unit (120) receives input data from a voltage comparison unit (140), a current comparison unit (150), a voltage detection unit (170) and a current detection unit (180), determines whether required conditions are fulfilled, such as whether an object is installed, whether the installed object is a battery pack (200), what the charge capacity of the battery pack (200) is, and whether the charging of the battery pack (200) has been completed, and controls a variable-voltage frequency generation unit (130) to be operated so as to correspond to the required conditions. Accordingly, the charging of the battery pack (200) is performed to correspond to the charging capacity of the battery pack (200) only when the battery pack (200) is installed.

Abstract: A method for transporting semiconductor wafers in semiconductor factory automation system, includes the steps of: a) processing a lot of semiconductor wafers to be contained in a semiconductor wafer cassette in a process equipment; b) sending a cassette transportation request from the process equipment to a cell management server when the process equipment has processed the lot of semiconductor wafers; c) generating a transportation instruction in response to the cassette transportation request; and d) if the semiconductor wafer cassette is transported from the process equipment to a stocker by an automatic guide vehicle (AGV), simultaneously activating the AGV and the stocker by simultaneously sending the transportation instruction to the AGV and the stocker. The method in accordance with the present invention can reduce a time taken to transport the semiconductor wafers.
