Publication number: 20220254169Abstract: A road surface inspection apparatus (10) includes an image acquisition unit (110), a damage detection unit (120), and an output unit (130). The image acquisition unit (110) acquires an input image in which a road is captured. The damage detection unit (120) detects a damaged part of the road in the input image by using a damage determiner (122) being built by machine learning and determining a damaged part of a road. The output unit (130) outputs, to a display apparatus (30), a determination result with a certainty factor equal to or less than a reference value in a state of being distinguishable from another determination result out of one or more determination results of a damaged part of a road by the damage determiner (122).Type: ApplicationFiled: June 28, 2019Publication date: August 11, 2022Applicant: NEC CorporationInventors: Kenichi YAMASAKI, Gaku NAKANO, Shinichiro SUMI

Patent number: 8740042Abstract: The invention provides a friction-welded part featuring easy design as well as a method of producing said part. The friction-welded part 1 is produced by friction-welding a first member 10 and a second member 20 together. The first member 10 is made of an aluminum alloy material, having a uniform cross-section portion 11 whose cross-sectional shape and size are not changed. The second member 20 is made of an aluminum alloy material, having a uniform cross-section portion 21 whose cross-sectional shape and size are not changed. According to the invention, the uniform cross-section portions 11 and 21 are friction-welded together to form the part 1. A heat affected zone “H” caused by friction welding is formed only in the uniform cross-section portions 11 and 21. The uniform cross-section portion 11 of the first member 10, and the uniform cross-section portion 21 of the second member 20, respectively, have a cylindrical shape, preferably having the same sectional dimension.Type: GrantFiled: July 19, 2006Date of Patent: June 3, 2014Assignees: Nippon Light Metal Company, Ltd., Nikkeikin Aluminium Core Technology Company Ltd.Inventors: Shinichiro Sumi, Kou Mizuguchi, Hiroyuki Mochizuki, Kazuhiro Nakakura

Patent number: 4760023Abstract: [21-Leucine] human urogastrone, hUG, comprising a polypeptide represented by the specified amino acid sequence has been found to be equivalent to the known hUG which has 21-Met and is disclosed together with its syntheses. Double-stranded polydeoxyribonucleotides comprising a structural gene for expressing the hUG, a recombinant plasmid comprising a structural gene for expressing the hUG, and E. coli transformed by the recombinant plasmid are also disclosed. Thanks to the substitution of Met in the known hUG by Leu, the peptide of hUG can now be produced by a conventional or typical method in which a genetically engineered precursor fused polypeptide is cleaved by cyanogen bromide at Met in the fused polypeptide.Type: GrantFiled: July 3, 1984Date of Patent: July 26, 1988Assignee: Wakunaga Seiyaku Kabushiki KaishaInventors: Kenichi Miyoshi, Shinichiro Sumi, Akira Hasegawa, Masanori Suzuki
