Publication number: 20240117218Abstract: Provided are a polishing method and a polishing composition that are applied to polishing of silicon carbide and allows reduction of rise in pH of the polishing composition and increase in pad temperature during polishing. Provided is a method of polishing an object to be polished having a surface formed of silicon carbide. The method includes steps of preparing a polishing composition, and supplying the polishing composition to the object to be polished and polishing the object to be polished. The polishing composition contains permanganate, a metal salt A, and water. The metal salt A is a salt of a metal cation having a pKa of less than 7.0 in form of a hydrated metal ion, and an anion.Type: ApplicationFiled: February 2, 2022Publication date: April 11, 2024Inventors: Yuichiro NAKAGAI, Hiroyuki ODA, Yasuki ITO, Shogaku IDE, Shinichiro TAKAMI

Publication number: 20230060781Abstract: Provided is a method of assisting the detection of nonalcoholic steatohepatitis (NASH), which is far less invasive than liver biopsy and is based on simple operations that do not require skilled technical personnel. The present invention is a method of assisting the detection of NASH, which includes: a) measuring the amount of LDL-TG contained in a test blood sample isolated from a living body; b) measuring the amount of at least one component selected from the group consisting of LDL-C, LDL subfraction-C, IIDL-C, HDL subfraction-C, ApoB, ApoE, total cholesterol, ALT, and AST contained in the test blood sample; and c) determining the possibility of developing and/or having NASH by using the amount of LDL-TG in combination with the amount of the at least one component.Type: ApplicationFiled: February 4, 2021Publication date: March 2, 2023Applicants: Denka Company Limited, NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITY, NATIONAL UNIVERSITY CORPORATION OKAYAMA UNIVERSITYInventors: Noriyuki SATOH, Yasuki ITO, Toshihiro SAKURAI, Masahiro MIZUTA, Shu-Ping HUI, Kazuhiro NOUSO, Hiroyuki OKADA

Publication number: 20210199676Abstract: Provided are a method of assisting the detection of nonalcoholic steatohepatitis (NASH) and a method that is able to assist in determining the degree of progression of any condition associated with NASH, which are far less invasive than liver biopsy and include simple operations and are independent of the skills of technicians. The present invention provides a method of assisting the detection of nonalcoholic steatohepatitis, including measuring the abundance of LDL-TG and/or ApoE-rich HDL-C contained in a test blood sample isolated from a living body.Type: ApplicationFiled: August 22, 2019Publication date: July 1, 2021Applicants: Denka Company Limited, NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITYInventors: Kazuhiro NOUSO, Yasuki ITO, Motoko OHTA, Hitoshi CHIBA, Toshihiro SAKURAI, Hiroyuki OKADA

Patent number: 8353227Abstract: A structure for sufficiently spacing a steering handle from a top bridge, thereby greatly improving design flexibility. A relief portion for allowing the deformation of a washer is formed to overlap a second contact surface and adjacent to a first contact surface as viewed in the axial direction of each bolt member. The first contact surface is located so as not to overlap the second contact surface as viewed in the axial direction of each bolt member. Therefore, a bending force acts on the washer to allow the deformation of the washer. That is, the washer can exhibit a spring function to relax the effect of the bending force. As a result, the steering handle can be sufficiently spaced from the top bridge to thereby greatly improve design flexibility.Type: GrantFiled: October 28, 2010Date of Patent: January 15, 2013Assignee: Honda Motor Co., Ltd.Inventors: Kosei Hayashi, Yasuki Ito, Shunichi Nakajima, Yoshitaka Seki, Terunari Saiki, Masataka Nakano

Patent number: 6893832Abstract: Disclosed is a method for quantifying cholesterol in HDL, which does not require complex fragmentation and separation operations, and by which the HDL cholesterol in test samples containing HDL and other lipoproteins such as low density lipoprotein (LDL), very low density lipoprotein (VLDL) and chylomicron (CM) may be quantified selectively, simply and accurately. The method for quantifying cholesterol in high density lipoprotein comprises a first step of erasing cholesterol in lipoproteins other than high density lipoprotein in a test sample, and a second step of adding a surfactant which specifically acts on high density lipoprotein to the product of the first step and enzymatically quantifying cholesterol in high density lipoprotein.Type: GrantFiled: July 9, 2002Date of Patent: May 17, 2005Assignee: Denka Seiken Co., Ltd.Inventors: Hiroshi Matsui, Yasuki Ito, Shuichi Ohara, Akira Fujiwara
