Abstract: Provided is an aluminum-resin bonded body that expresses excellent bonding strength and does not show a reduction in the strength after a durability test, thus being able to keep the excellent bonding strength over a long period of time. The aluminum-resin bonded body includes: an aluminum substrate formed of aluminum or an aluminum alloy; an oxygen-containing film containing oxygen, which is formed on a surface of the aluminum substrate; and a molded resin formed of a thermoplastic resin, which is bonded onto the oxygen-containing film. The thermoplastic resin is a thermoplastic resin containing an element having an unshared electron pair in a repeat unit and/or at an end.

Abstract: This invention provides an aluminum electrode plate for an electrolytic capacitor, which, even when the thickness of an etching layer is large, can realize a high level of impregnation of a solid electrolyte and can reduce ESR of a capacitor. An aluminum plate having an aluminum purity of not less than 99.98% by mass is etched to form an etching layer having a depth of 70 ?m or above. When a plane cross section of a position deeper than 20 ?m from the surface in the etching layer is measured with an image analyzer, for each measured face, not less than 70% of the total number of pits within the measured face is accounted for by pits having a diameter of 0.01 to 1 ?m ?; in terms of equivalent circle diameter. The aluminum plate has an aluminum purity of not less than 99.98% by mass and comprises 5 to 50 ppm of Fe and 5 to 40 ppm of Cu with the balance consisting of inevitable impurities.

Abstract: An aluminum plate having an aluminum purity of not less than 99.98% by mass and an Fe content of 5 to 50 ppm with the balance consisting of unavoidable impurities is used to realize increased capacitance of an aluminum electrolytic capacitor, reduced height, and improved high frequency characteristics. In this aluminum plate, the total content of Fe in crystal/precipitate is 1 to 50% based on the original content, and the thickness of the aluminum plate 0.2 to 1 mm. In the formation of a capacitor anode, the aluminum plate is subjected to alternate current etching so as to leave a core part having an average thickness of 50 to 150 ?m in the center part in the thickness-wise direction to increase the surface area, followed by anodic oxidation.

Abstract: Disclosed is a shoe sole comprising an outer sole 1F, 1B, a midsole 2 and a reinforcement device 4 made of a resin plate. The reinforcement device 4 is firmly secured to the underside of an arch portion 2M of the midsole 2. At a medial side 11 and a lateral side 10 of the foot, the reinforcement device 4 is shaped like an arch between separated outer sole parts 1F and 1B. A medial foot portion 43 of the reinforcement device 4 is formed to have a higher hardness than a lateral foot portion 40 of the reinforcement device 4. This allows the reinforcement device 4 to have a greater flexural rigidity in its medial foot portion 43 than in its lateral foot portion 40.
