Abstract: An information processing apparatus performs electromagnetic field analysis over a plurality of stages. The information processing apparatus includes a hardware processor connected to a memory. The hardware processor sequentially selects an analysis target and determines one or more analysis regions in the analysis target. The one or more analysis regions are determined on the basis of a parameter relative to mutual influence between structures included in the analysis target. The hardware processor performs electromagnetic field analysis on the one or more analysis regions. The structures include a first structure and a second structure. At least one of the one or more analysis regions includes an entirety of the first structure and part of the second structure.

Abstract: Provided is a secondary battery in which corrosion of an exterior body is stably suppressed. A non-aqueous electrolyte secondary battery according to an embodiment of the present disclosure comprises: an exterior body having a bottomed cylindrical shape and having a grooving portion in an opening portion; an electrode body and a non-aqueous electrolyte housed in the exterior body; and a sealing body caulked and fixed between the grooving portion and an opening end in the opening, wherein in a portion from the grooving portion of the inner surface of the exterior body to the open end portion, a powder of at least one among compounds selected from the group consisting of hydroxides, oxides, and carbonates is present.

Abstract: A feed element is disposed over a surface of a first conductor. A second conductor is disposed at a distance from the feed element greater than a distance between the feed element and the surface. The second conductor has a second shape that is a sheet-like shape in plan view. The second conductor is disposed to overlap the surface of the feed element. At least a part of the third conductor is located closer to the first conductor than the second conductor is located, in a direction perpendicular to the surface of the second conductor. The at least part of the third conductor is located farther than a part of the second conductor with respect to the feed element. A second distance between the at least part of the third conductor and the first conductor is less than twice a first distance between the feed element and the first conductor.
