A lamination shaping apparatus has a powder layer preparing means and an optical unit which irradiates a light beam to an intended portion of a powder layer so as to sinter or melt for solidifying the portion into a cured layer. Preparation of the powder layer and curing of the cured layer are repeated to fabricate a three-dimensional object in which a plurality of the cured layers are laminated and integrated. The apparatus includes a fixed base carrying thereon the powder layer and the cured layer, an elevator frame surrounding a periphery of the fixed base, and driving means for driving the elevator frame to move vertically. The powder layer is formed within a space above the base and surrounded by an interior surface of the elevator fame such that the powder layer (cured layer) can be stacked on the base with the base being kept at a fixed position, thereby facilitating to fabricate a precisely shaped object.

In a magnet-exciting rotating electric machine system, a rotor surface has magnetic salient poles and island-shaped magnetic poles alternately in circumferential direction, and the island-shaped magnetic poles are constituted so that magnetic flux coming from an external source does not flow through. A magnetic excitation part magnetizes the island-shaped magnetic poles and the magnetic salient poles collectively in the same direction, and then control a flux amount flowing through an armature. The armature has armature coils that face the magnetic salient pole and the island-shaped magnetic pole simultaneously so that driving torque fluctuation or power generation voltage waveform distortion is controlled. The magnetic excitation part changes magnetization state of a field magnet irreversibly, or changes an excitation current to an excitation coil to control a flux crossing the armature.

The present disclosure provides a manufacturing method for a touch panel comprising: disposing an electrode layer extending from touch area of a substrate to periphery area of the substrate, wherein the periphery area surrounds the periphery of the touch area. The method further includes disposing an insulation layer in the periphery area of the substrate to form a shielding layer, making the shielding layer cover the overlapping electrode in the periphery area and making the electrode layer of the touch area and the overlapping electrode locate on the same layer of the substrate so as to avoid fluctuation of resistance value in the electrode layer due to height difference. Meanwhile, adopting the disposition method also maintains insulating performance of the shielding layer. The present disclosure also provides a touch panel made by the manufacturing method.

A groove is formed in a ring shape and a ring-shaped convexity is formed on the periphery of a through-hole of a positive electrode terminal plate. An upper end side of a crimping part of a positive electrode exterior terminal is inserted through the through-hole of the positive electrode terminal plate and crimped, and welded spots are formed by irradiation with high-energy beams between a distal end side of the crimping part and the convexity. The mechanical and electrical connection of an exterior terminal and a terminal plate to the crimping part through welding with high-energy beams makes it possible to provide a prismatic secondary battery of enhanced reliability in which cracking is less likely to occur in the welded spots, the coupling strength between the exterior terminal and the terminal plate is increased, and fluctuations in the internal resistance are curbed.
