[Object] To regularize a potential distribution at a grid, prevent local corrosion, and lengthen product lifetime.[Solution Means] A storage battery grid includes: a frame bone 2 that includes a substantially rectangular shape; a lug portion 21 that is formed upward from an upper side 2a of the frame bone 2; one or more main vertical bone 3X that extend downward from the lug portion 21 in the frame bone 2; plural slanted bones 4 that extend obliquely from the upper side 2a toward a lower side 2b, at least the slanted bones branching from the main vertical bone 3X, which is a center, toward both sides. The slanted bones 4 are arranged at intervals in a direction in which the main vertical bone 3X extends, and at least part of plural spaces, which are defined by the main vertical bone 3X partially forming a side of the spaces, include a substantially quadrilateral shape.
摘要:
A circuit board including a base member, an interconnect layer formed on a part of the base member, an electrically-floating conductive layer formed on a substantially remaining part of the base member and having an edge adjacent to an edge of the interconnect layer, and a dielectric layer covering a part of the interconnect layer and an entire surface of the electrically-floating conductive layer and filling a gap between the edge of the interconnect layer and the edge of the electrically-floating conductive layer. In accordance with the present invention, almost all the surface of the base member is covered with the interconnect layer and the floating conductive layer disposed parallel to each other on a substantially single plane. In the circuit board, the moisture does not enter into the rear surface of the dielectric layer through the externally exposed portion to improve the packaging rank.

In a non-volatile semiconductor memory device making electrical writing and erasing possible, source diffusion layers arranged on a substrate and along at least control gate electrodes have, in one part thereof, inclined portions having an angle larger than an ion implantation angle. According to this, device isolation technique is used to lower the resistance of the source diffusion layer.
