Publication number: 20240110897Abstract: A second polymer is prepared through derivatization of a first polymer. Kendrick Mass Defect (KMD) analysis is applied on a mass spectrum of the second polymer, to thereby produce a plot. Meanwhile, a plurality of mass candidates for a non-primary-chain segment are calculated based on a mass spectrum of the first polymer. The KMD analysis is applied on the plurality of mass candidates, to thereby produce reference images. A mass of the non-primary-chain segment is identified through matching of two KMD analysis results.Type: ApplicationFiled: September 28, 2023Publication date: April 4, 2024Inventors: Takaya Satoh, Masahiro Hashimoto, Haruo Iwabuchi

Patent number: 6699592Abstract: The invention provides a galvannealed steel sheet which has an oxide layer having 10 nm or larger thickness on the plateau of the coating layer flattened by temper rolling. With the use of the galvannealed steel sheet, no powdering occurs during press-forming, and stable and excellent sliding performance is attained. By selecting the area percentage of the plateau of the flattened coating layer to a range from 20 to 80%, making the coating layer single layer of &dgr;1 phase, and letting &zgr; phase exist in the &dgr;1 phase, further improved sliding performance and anti-powdering property are obtained.Type: GrantFiled: October 21, 2002Date of Patent: March 2, 2004Assignee: NKK CorporationInventors: Shoichiro Taira, Yoshiharu Sugimoto, Junichi Inagaki, Toru Imokawa, Shuji Nomura, Michitaka Sakurai, Masaaki Yamashita, Kaoru Sato, Masayasu Nagoshi, Akira Gamou, Yoichi Miyakawa, Shunsaku Node, Masahiro Iwabuchi
