20150143302 | METHOD OF PROVIDING VIRTUAL REALITY BASED THREE-DIMENSIONAL INTERFACE FOR WEB OBJECT SEARCHES AND REAL-TIME METADATA REPRESENTATIONS AND WEB SEARCH SYSTEM USING THE THREE-DIMENSIONAL INTERFACE - A method of providing a virtual reality-based three-dimensional interface for a web object search and a real time metadata representations and a web search system using the three-dimensional interface thereof are provided. In this method, a plurality of nodes each in which a node identification label string to which an information page is linked is together written and a plurality of links connecting the plurality of nodes, respectively, are displayed in a three-dimensional form that is either static or spinning. Thereafter, by performing an action of reduction, enlargement, movement, rotation, expanding, hiding, removal, and addition in a three-dimensional object that is formed with the node and the link that are displayed in the three-dimensional form according to a user input, the three-dimensional object is displayed or an information page that is linked to a node that is selected by the user is displayed. | 05-21-2015 |

20110159314 | QUENCHABLE STEEL SHEET HAVING HIGH HOT PRESS WORKABILITY AND METHOD OF MANUFACTURING THE SAME - The quenchable steel sheet has an alloy composition including carbon (C) in an amount of 0.15˜0.30 wt %, silicon (Si) in an amount of 0.05˜0.5 wt %, manganese (Mn) in an amount of 1.0˜2.0 wt %, boron (B) in an amount of 0.0005˜0.0040 wt %, sulfur (S) in an amount of 0.003 wt % or less, phosphorus (P) in an amount of 0.012 wt % or less, one or more selected from among calcium (Ca) in an amount of 0.0010˜0.0040 wt % and copper (Cu) in an amount of 0.05˜1.0 wt %, two or more selected from among cobalt (Co), zirconium (Zr) and antimony (Sb), and iron (Fe). Alloy elements are controlled to increasing hot ductility and enabling pressing at 600˜900° C. so that a tensile strength of 1400 MPa or more and an elongation of 8% or more are obtained after pressing. | 06-30-2011 |
20130014555 | QUENCHABLE STEEL SHEET HAVING HIGH HOT PRESS WORKABILITY AND METHOD OF MANUFACTURING THE SAME - The quenchable steel sheet has an alloy composition including carbon (C) in an amount of 0.15 to 0.30 wt %, silicon (Si) in an amount of 0.05 to 0.5 wt %, manganese (Mn) in an amount of 1.0 to 2.0 wt %, boron (B) in an amount of 0.0005 to 0.0040 wt %, sulfur (S) in an amount of 0.003 wt % or less, phosphorus (P) in an amount of 0.012 wt % or less, one or more selected from among calcium (Ca) in an amount of 0.0010 to 0.0040 wt % and copper (Cu) in an amount of 0.05 to 1.0 wt %, two or more selected from among cobalt (Co), zirconium (Zr) and antimony (Sb), and iron (Fe). Alloy elements are controlled to increasing hot ductility and enabling pressing at 600 to 900° C. so that a tensile strength of 1400 MPa or more and an elongation of 8% or more are obtained after pressing. | 01-17-2013 |
