The dielectric ceramic composition comprises a main component of (Ba1?xCax)mTiO3; and sub-components including MgCO3, RE2O3, MO, MnO, V2O5, Cr2O3 and a sintering additive of SiO2. RE2O3 is at least one selected from the rare earth oxide group consisting of Y2O3, Dy2O3 and Ho2O3, and MO is one of Ba and Ca. The dielectric ceramic composition is expressed by a following formula: a(Ba1?xCax)mTiO3-bMgCO3-cRE2O3-dMO-eMnO-fSiO2-gV2O5-hCr2O3. Here, a, b, c, d, e, f, g, and h satisfy following relationships: in mole fraction, a=100, 0.1?b?3.0, 0.1?c?3.0, 0.1?d?3.0, 0.05?e?1.0, 0.2?f?3.0, 0.01?g?1.0, and 0.01?h?1.0, and x and m satisfy following relationships: 0.005?x?0.15, and 0.995?m?1.03.

Abstract: A dual-stage air bag module for a passenger seat capable of easily controlling and changing gas pressures to be provided into an air cushion, and also implementing a miniaturization and a lightweight of the air bag module. The first and second inflators, which are controlled by a control unit, are arranged in a diagonal direction to each other within a housing. The first and second inflators are generally inflators for a driver seat air bag modules mounted in a steering wheel. The retainer is fixed in the state that a portion thereof is received in the upper portion of the housing in order to fix the cushion holder assembled with the air cushion within the housing. The retainer is coupled through a predetermined coupling member to the housing with the first and second inflators.

Abstract: A variable cover of a curtain airbag for a vehicle includes a plurality of bellows, which control the angle and the extending length of a circular or a polygonal shaved cover. The variable cover also includes a rupturing part, which guides the spreading direction of an airbag cushion via hooks or scoring. The combination of features provided by the variable cover is standardized to accommodate the roof side rail of different vehicles.

Abstract: A membrane horn switch structure of an airbag module does not include a back plate, which simplifies an inner configuration of a bag cover and ensures stable operation. The structure includes an outer support plate installed on a plurality of protrusions formed at an inner bottom of the bag cover, the outer support plate including a pair of films having edges which are sealed to form an inner space. A membrane horn switch unit includes a pair of inner support plates having an arc shape, which are installed in the outer support plate. The inner support plates are overlapped and spaced apart from each other. One end of each inner support plate is fixed to the outer support plates, and the other end of each inner support plate is free, so that the inner support plates are in contact with each other when the outer support plate is pressed.

Abstract: Disclosed is a variable cover of a curtain airbag for a vehicle, comprising a plurality of bellows, which can control the angle and length of the cover which has a circular or polygonal shape, and an exploding part, which guides the spreading direction by being exploded by an exploding pressure of an airbag cushion, by a hook or a scoring process. This can guide the standardization of a cover which can be applied to the roof side rail of different vehicles. Thereby, it contributes to reduce the manufacturing cost by preventing manufacturing the cover individually in accordance with the existing vehicles and enhance a worker's convenience by aiming at an uniformity of the working process.

Abstract: Disclosed is a membrane horn switch structure of an airbag module which does not use a back plate in order to simplify an inner configuration of a bag cover and ensures stable operation by changing configuration of the membrane horn switch.

Abstract: A heat sink is provided with a box-like body attached to heat dissipating surface of a heat-dissipating element. A separation board separates the box-like body into upper and lower parts. A number of side separation boards divide the lower part into several areas, and nozzle parts are inserted into the side separation boards parallel to the attaching surface. Pin-like fins are formed in the bottom face in the several areas divided by the side separation boards and an air carrying means is provided at an upper area formed by the separation board for supplying cooling air to fins through the nozzle parts.
