摘要:
An apparatus and method for controlling the position of the tongs of a crane depending on bending of a slab are disclosed. Side surface detection units are installed at both ends of the tongs of a crane for gripping the side surfaces of one or more slabs, and are configured to detect one or more gaps generated due to bending of one of the slabs. A distance detection unit is configured to detect the distance between an uppermost slab and the crane. A control unit is configured to adjust the final grip position of the tongs using information about the gaps generated due to the bending of the slab. The information about the gaps is detected by the side surface detection units and the distance detection unit.

A method of manufacturing a ceramic primary crown including mixing a source material including zirconia or alumina that configures a frame of a primary crown, a polymer for reducing viscosity and applying ductility upon injection molding, and a toner for providing the same or similar color as baby teeth, heating the polymer contained in the mixed source material to have ductility, injection molding the heated source material, extracting the polymer to reduce brittleness and increase ductility with respect to the injection-molded matter, removing fat to completely eliminate the polymer element from the injection-molded matter, from which the polymer is partially extracted through the polymer extraction, sintering the fat-removed body, from which the polymer is removed, to improve mechanical properties, and polishing an outer surface of the sintered body to provide gloss, and performing barrel-finishing to remove a burr.
摘要:
Disclosed is a thermoplastic polyolefin (TPO) nanocomposite composition, more particularly a TPO nanocomposite composition including a polypropylene resin, a polyethylene resin, a rubber resin, a nanoclay master batch and a glass bubble master batch. Since the disclosed TPO nanocomposite composition has low specific gravity and superior gloss reducing effect and scratch resistance, it may be usefully applied to light automobile parts, uncoated automobile exterior parts, or the like.

摘要:
The present invention relates to a process for removing methionine (Met) residue at N-terminus of proteins specifically. Particularly, the present invention relates to an aminopeptidase which is purified from Bacillus licheniformis removes a methionine residue from N-terminus of peptide and proteins. And the present invention relates to a process for preparing a natural type protein from proteins produced in microorganisms by recombinant DNA technology. Various kinds of natural type proteins such as human growth hormone (HGH) can be prepared massively and easily by the process of the present invention.
