Abstract: The method of forming a Te-containing chalcogenide layer includes radicalizing a first source that contains Te to form a radicalized Te source, and forming a Te-containing chalcogenide layer by supplying the radicalized Te source into a reaction chamber. A method fabricating a phase change memory device includes loading a substrate on which a lower electrode is formed into a reaction chamber, radicalizing a first source that contains Te to form a radicalized Te source, forming a phase change material film containing Te on the lower electrode by supplying the radicalized Te source into the reaction chamber, and forming an upper electrode on the phase change material film.

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 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 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 horn switch integrated with an airbag module, which is capable of utilizing the inside of a steering wheel more effectively by changing the mounting structure of a horn switch unit installed in the steering wheel, includes a fixed plate fixed in the steering wheel, a moving plate supported vertically movable by a plurality of coil springs mounted at an upper portion of the fixed plate and contacted with a lower portion of the airbag module, and a horn switch unit formed at an upper surface of the fixed plate and generating a horn when the moving plate is moved near or in contact with the fixed plate.
