Patent application numberDescriptionPublished
20090126174METHOD OF MANUFACTURING MULTI-LAYER CERAMIC CONDENSER - There is provided a method of manufacturing a multi-layer ceramic condenser. A method of manufacturing a multi-layer ceramic condenser may include: laminating a plurality of dielectric green sheets having internal electrodes formed thereon to form a laminate; forming through holes in a region of the laminate where an external electrode is to be formed; filling the through holes with conductive paste to form the external electrode; cutting the laminate having the external electrode formed thereon; and firing the cut laminate to form at least one multi-layer ceramic condenser.05-21-2009
20100053908Electric device module - There is provided an electric device module including: a housing; a board member fixed to one inner side of the housing and including a plurality of connecting terminals; at least one board adhered to another inner side of the housing by a predetermined adhesive and including a plurality of terminals electrically connected to the plurality of connecting terminals; and a guider guiding a mounting position of the board. In the electric device module, a circuit board is prevented from changing in adhering position due to fluidity of an adhesive but can be adhered at a precise position. Also, an extra amount of the adhesive is prevented from flowing outside the circuit board to thereby enhance accuracy and reliability in terms of terminal connection.03-04-2010
20110149530PRINTED CIRCUIT BOARD ASSEMBLY - There is provided a printed circuit board assembly including a printed circuit board having a plurality of circuit elements mounted on an upper surface thereof, and a power line mounted on a lower surface of the printed circuit board and supplying power to the circuit elements.06-23-2011
20110156740PROBE CARD - There is provided a probe card. A probe card according to an aspect of the invention may include: a printed circuit board; a horizontal regulator passing through the printed circuit board and having an insertion portion having a horizontal regulation bolt and an insertion portion having a curved portion provided on an end portion of the horizontal regulation bolt; a probe substrate electrically connected to the printed circuit board; and a connection member mounted on the probe circuit, engaged with the horizontal regulation portion, and having an insertion recess therein so that the insertion portion is rotated within the insertion recess.06-30-2011

20110079403FIRE SAFETY APPARATUS OF HIGH-PRESSURE GAS FUEL TANK FOR VEHICLE - The present invention features a fire safety apparatus for a high-pressure gas fuel tank of a vehicle, comprising a pressure relief device that is disposed between a tank connection channel and an outside connection channel in a tank valve of a high-pressure fuel tank and that connects the tank connection channel with the outside connection channel when the tank valve increases in temperature over a predetermined level in a fire, and a suitable intumescent that is hydrate disposed with the high-pressure fuel tank to increase in volume and absorbs heat, with the water from evaporation in a fire, and delay the flames spreading over the high-pressure fuel tank by producing a heat insulation barrier after the water evaporates.04-07-2011
20110083756COMPRESSED GAS SAFETY DISCHARGE SYSTEM - The present invention provides a compressed gas safety discharge system preventing a pressure vessel from breaking and exploding by appropriately and timely operating a pressure relief device, conditions of a fire, such as when a fire occurs around the pressure vessel far from the pressure relief device as well as close to the pressure relief device.04-14-2011
20110127263FIRE SAFETY APPARATUS OF HIGH-PRESSURE GAS FUEL TANK FOR VEHICLE - The present invention relates to a fire safety apparatus for a high-pressure fuel tank of a vehicle, which can prevent a high-pressure fuel tank from exploding due to a fire and preferably preclude secondary damage due to high-pressure fuel tank, by forcibly discharging the high-pressure gas in high-pressure fuel tank, using a pressure operator, before high-pressure fuel tank is damaged and exploded by flame in a vehicle on fire.06-02-2011
