Abstract: A lightweight air bag apparatus which facilitates the positioning between an instrument panel and a lid, and to provide an air bag apparatus in which the lid is not attached to a retainer in substance. The air bag apparatus includes a retainer, an air bag which is folded and stored in the retainer, a lid which covers the open surface of the retainer, and an inflator (gas generator) for expanding the air bag. The external surfaces of the retainer are surrounded by belts, and both ends of the belts are fixed to the leg portions and with rivets, bolts, or other fittings. The peripheral portion around an opening formed in the instrument panel is clamped between the edge portion of the lid and the extending portions. The belts are not connected to the retainer.

Abstract: A protection bag for an automobile includes an introducing chamber extending along an upper side of the bag, and a plurality of small chambers disposed parallel to each other at a lower side of the introducing chamber. Some of the small chambers have a spiral shape. Gas inlet of the spiral small chamber faces a pass through port. The length of a gas flowing path of the small chamber is greater than the width of the small chamber. The protection bag can avoid outflow of gas from the small chambers and sufficiently absorb the impact on the passenger's head.

Abstract: A cover for an air bag device that enables an emblem to be secured to the cover in an extremely simple manner. The cover (module cover) has a recess for receiving the emblem. An extension of the emblem is extended through a hole in the cover. A distal end of the extension is bent along a rear side of the cover. A rib is pressed and welded by a thermal or ultrasonic welding element to form a welding body. The welding body covers the distal end of the extension.

Abstract: A passenger protecting apparatus that prevents a submarine phenomenon of the passenger by the use of an air belt, or that can protect the passenger by applying a pretension to the webbing. The apparatus includes a seat cushion that includes a seat pad, and an air belt disposed under the seat pad. The air belt includes a buckle and a lap anchor. The rear end on the right and the left of the air belt are connected to the buckle and the lap anchor via a wire respectively. Upon collision, the air belt is inflated and the front portion of the seat pad is pushed up so that a submarine phenomenon is prevented and the buckle and the lap anchor are pulled down.

Abstract: A method is presented for cleaning of metallic surface contaminants from the surfaces of semiconductor substrate in semiconductor device manufacturing. The method is a dry method and avoids many of the problems introduced by the conventional wet method of cleaning while achieving a level of cleanliness better than the wet method. The method involves halogenizing the contaminants by exposing the wafers to a gas containing a halogen gas to form halogenized compounds of the contaminants. This is followed by a process of exposing the halogenized compounds to a gas containing .beta.-diketone so as to convert the halogenized compounds to .beta.-diketone complexes to enable highly efficient removal of the metallic surface contaminants by vaporization.
