  • Patent number: 7618744
    Abstract: A thin film lithium battery is provided which can realize a high yield by solving various problems caused by a pin hole formed in a solid electrolyte layer. A thin film lithium battery according to the present invention is a thin film lithium battery in which a positive electrode layer 20, a negative electrode layer 50, a solid electrolyte layer 40 provided therebetween, and a collector 10 electrically connected to at least one of the positive electrode layer 20 and the negative electrode layer 50 are laminated to each other. When this battery is viewed in plan along the lamination direction of the above individual layers, the positive electrode layer 20 and the negative electrode layer 50 are disposed at positions so as not to be overlapped with each other. By the structure as described above, even if a pin hole is formed in the solid electrolyte layer 40, short-circuiting between the two electrode layers 20 and 50, which is caused by this pin hole, can be prevented.

  • Patent number: 6422602
    Abstract: An air bag wherein a peripheral wall portion on one side opposite to an opening for introducing an inflation gas is put on the side of a peripheral wall portion having the opening and flattened. The peripheral edges around the opening are folded together closer to the opening side at the first stage. Peripheral edges on the end portion side thus folded around the opening are folded at the second stage in such a manner as to set the peripheral edges closer to the opening side whereby to house the air bag in a casing. The region of an air bag cover which is positioned above and substantially closer to a center of the air bag thus folded up is thick-walled so that the region thereof may protrude downward from the periphery of the air bag.
