Abstract: A bag for an air bag apparatus activated when a vehicle rapidly decelerates is disclosed. The bag includes a plurality of straps and vent holes used for discharging gas. The vent holes are normally blocked by strap valves each of which are sewn to the bag to form a low strength stitch. Each of the strap valves and each of the straps are sewn together to form a high strength stitch. When a separating force produced between each of the straps and the bag reaches a given value upon the rapid deceleration of the vehicle, the low strength stitch is broken to unblock the vent holes. Hence the bag rapidly expands toward the occupant.

Abstract: In an air bag apparatus, a bag body has a bag body opening portion. The bag body opening portion communicates with a gas generating apparatus for generating gas when a vehicle rapidly decelerates. Further, the bag body is expanded by gas generated from the gas generating apparatus. A base plate holds a peripheral edge of the bag body opening portion. A plurality of reinforcing materials is superposed in layered fashion on the peripheral edge of the bag body opening portion to reinforce the bag body. One portion is held by a base member. The plurality of reinforcing materials are respectively sewn to the reinforcing materials contacting the bag body.

Abstract: A method for forming a superconducting circuit is disclosed, comprising the steps of forming a mask pattern on a superconducting layer, forming a covering layer, containing a modifying element for superconductor, on the resultant structure, diffusing the modifying element for a superconductor, which is contained in the covering layer, into the superconducting layer to modify a corresponding location to a nonsuperconducting layer. A method for forming a multi-layer superconducting circuit is also disclosed, comprising sequentially repeating the same steps as set forth above over a substrate.

Abstract: A method for manufacturing a superconductive multilayer circuit has a first thin film forming step for forming a thin film, which is composed of superconductive material or a similar material thereto, on a substrate, a first circuit layer forming step for forming a superconductive circuit by discharging a specific component from a predetermined part of the thin film or implanting the component in the thin film, a second thin film forming step for forming a thin film, which is composed of a superconducting material or the simulant thereto, on the first circuit layer, and a second circuit layer forming step for forming a superconductive circuit by removing a specific component from a predetermined part of the thin film or implanting the component in the thin film.

Abstract: A gas bag interposed between an occupant and a vehicle while inflating the gas bag. Longitudinally opposite end portions of at least one strap are retained on a body of the gas bag and an intermediate portion of the strap is threaded through a plurality of through-holes formed in the bag body so as to maintain a predetermined configuration of the bag body during inflation thereof. Accordingly, the installation of the strap on the bag body is facilitated.

Abstract: A seat belt system provided with a take-up apparatus for taking up a webbing to be placed around an occupant in layers around a take-up shaft comprises high-friction portions which are provided in a portion remaining wound around the take-up shaft when the webbing is placed around the occupant and which each have a larger coefficient of friction than that of the webbing. It is therefore possible to reduce tightening of the portion remaining wound around the take-up shaft when the webbing is placed around the occupant.

Abstract: An occupant restraining webbing employed in a seatbelt system for a vehicle includes warp which has a dry tenacity of 8.8 gr/De or more, a thickness of 1,700 De or less and a twist multiplier of 3,100 to 5,500. Thus, it is possible to reduce the extra amount by which the webbing is undesirably wound off after the rotation of a takeup shaft for winding off the webbing from a webbing retractor has ceased.
