20110027604 | EXPANDABLE METAL MEMBRANE WITH ORTHOGONALLY ISOTROPIC BEHAVIOR - In a metal membrane for a low-temperature-fluid storage tank wherein longitudinal and transverse corrugations are formed and both corrugations intersect each other, a bidirectional expandable member connected to each corrugation is formed in the intersection of the corrugations so that the bidirectional expandable member is longitudinally and transversely expandable. The bidirectional expandable member is protruded and is shaped like a pyramid, a dome or a cross. Each metal membrane is welded into a unit panel and the edge of each metal membrane is welded with the common edge of another adjacent metal membrane. | 02-03-2011 |
20120118615 | METAL CLAD LAMINATE, METHOD OF MANUFACTURING THE SAME, AND HEAT-RADIATING SUBSTRATE - Disclosed herein is a metal clad laminate, a method of manufacturing the same and a heat-radiating substrate using the same. The metal clad laminate has increased adhesion because a layer of carbon nanoparticles is formed between bonding surfaces of upper and lower metal foils to a prepreg, and has improved heat conductive properties and mechanical properties because the prepreg has carbon fibers incorporated therein. Also, resin members having carbon nanofibers incorporated therein may be alternately stacked with metal layers, and metal layers may be inserted in the prepreg thus improving heat conductive properties, and the number of stacked layers may vary depending on the end use thereby controlling heat conductive properties and mechanical properties of the metal clad laminate. | 05-17-2012 |
20120121361 | LOOSE PREVENTING ASSEMBLY - Disclosed herein is a loose preventing assembly including a bolt, a fastening member, and a pin-spring washer coupled between the bolt and the fastening member. The pin-spring washer includes a spring washer portion, a curved portion of which one end is connected to the spring washer portion to be curved upward and the other end is positioned in an inward direction of the spring washer portion, and a pin portion which extends in one direction from the other end of the curved portion tightens the bolt to couple the pin portion to an insertion groove formed in the bolt, thereby preventing the bolt and the fastening member from being loosened from each other. | 05-17-2012 |
20120122278 | Method Of Manufacturing Semiconductor Package Board - Disclosed herein is a method of method of manufacturing a semiconductor package board, including: providing a substrate including a connection part formed on one side thereof, the connection part being provided thereon with a solder layer; disposing a conductive heat generator equipped with current wiring on the solder layer; applying current to the current wiring and thus heating the solder layer to attach a semiconductor chip to the connection part; and removing the current wiring from the conductive heat generator. The method is advantageous in that the semiconductor chip is attached to the substrate by applying current to the current wiring of the conductive heat generator to locally heat only the solder layer, thus reducing thermal stress and preventing the deformation of the substrate. | 05-17-2012 |
20120127681 | SOLDERING CONNECTING PIN, SEMICONDUCTOR PACKAGE SUBSTRATE AND METHOD OF MOUNTING SEMICONDUCTOR CHIP USING THE SAME - Disclosed herein are a soldering connecting pin, a semiconductor package substrate and a method of mounting a semiconductor chip using the same. A semiconductor chip is mounted on the printed circuit board using the soldering connecting pin inserted into a through-hole of the printed circuit board, thereby preventing deformation of the semiconductor package substrate and fatigue failure due to external shocks. | 05-24-2012 |
20120139098 | POWER PACKAGE MODULE - Disclosed herein is a power package module, including: a power package mounted with a plurality of semiconductor chips; a heat radiation module coming into contact with the power package and including a first heat radiation member for discharging heat generated from the power package; and a second heat radiation member, one side of which is connected to the first heat radiation member and the other side of which is connected to the power package. | 06-07-2012 |
20150114970 | REINFORCING MEMBER FOR CORRUGATED MEMBRANE OF LNG CARGO TANK, MEMBRANE ASSEMBLY HAVING THE REINFORCING MEMBER AND METHOD FOR CONTRUCTING THE SAME - The present invention is related to a reinforcing member for a membrane for improving the pressure-withstanding property of the membrane having corrugations, and a membrane assembly having the reinforcing member and a method of constructing the membrane assembly. By providing a reinforcing member for a membrane having corrugations and installed in an insulating structural member of an LNG cargo, the present invention can prevent the collapse of the corrugation and attenuate shocks against a same load without increasing the facial rigidity of the corrugation, and improve the insulating property by forming an additional insulating layer. | 04-30-2015 |
