Patent number: 8691619Abstract: This invention aims to provide a laminated structure and an integrated structure of a high production efficiency for a CIS based thin-film solar cell, which can produce a high-resistance buffer layer of the CIS based thin-film solar cell efficiently on a series of production lines and which needs no treatment of wastes or the like, and a manufacturing method for the structures. The CIS based thin-film solar cell includes a back electrode, a p-type CIS based light absorbing layer, a high-resistance buffer layer and an n-type transparent conductive film laminated in this order. The high-resistance buffer layer and the n-type transparent conductive film are formed of thin films of a zinc oxide group. The buffer layer contacts the p-type CIS based light absorbing layer directly, and has a resistivity of 500?·cm or higher.Type: GrantFiled: November 25, 2008Date of Patent: April 8, 2014Assignee: Showa Shell Sekiyu, K.K.Inventors: Hideki Hakuma, Katsuya Tabuchi, Yosuke Fujiwara, Katsumi Kushiya

Patent number: 8109578Abstract: Bolt holes 23 are provided for press fitting and securing bolts 5 for mounting a brake rotor 4 to a flange 22 of a hub wheel. Each bolt hole 23 includes widening portions 28a, 28b, which are tapered to widen from the center portion of the bolt hole 23 toward a brake rotor mounting surface 25 of the flange 22. The widening portions 28a, 28b are formed by two tapered surfaces having different taper angles with respect to the axis of the bolt hole 23 from an opening rim of the bolt hole toward the inside. The taper angle of an outer tapered surface connected to the opening rim is greater than the taper angle of an inner tapered surface connected to the outer tapered surface. In machining the hub wheel 2 configured as described above, the brake rotor mounting surface 25 is finished after machining the bolt holes 23.Type: GrantFiled: July 23, 2007Date of Patent: February 7, 2012Assignee: JTEKT CorporationInventors: Yosuke Fujiwara, Kouichi Shimizu
