Patent number: 8916476Abstract: Provided are a method for forming a microfine structure and a microfine structure forming body prepared by the method. The method allows a remaining film part to be formed thinner and more uniform on a substrate than the conventional techniques. The method comprises the steps of: forming an oxide layer on a metallic thin film; a photocurable resin layer via first and second adhesive layers over the oxide layer; and transferring a microfine structure formed on a mold by pressing the mold onto the photocurable resin layer. The first adhesive layer includes a compound having at least two hydrolysable functional groups, and the second adhesive layer includes a compound having at least a hydrolysable functional group and a reactive functional group.Type: GrantFiled: November 20, 2013Date of Patent: December 23, 2014Assignee: Hitachi-LG Data Storage, Inc.Inventors: Ryuta Washiya, Masahiko Ogino, Shiro Nagashima, Akio Yabe, Masaki Sugita, Akihiro Miyauchi

Publication number: 20130041178Abstract: The present invention relates to a method for preparing optically active N-methylamino acids and/or optically active N-methylamino acid amides by subjecting the cells or treatment products of a microorganism belonging to the Mycoplana genus to the hydrolysis with N-methylamino acid amide to give an optically active N-methylamino acid and an optically active N-methylamino acid amide. According to the present invention, optically active N-methylamino acids and optically active N-methylamino acid amides useful as the raw material of pharmaceuticals can be stereoselectively obtained with good efficiency.Type: ApplicationFiled: March 15, 2011Publication date: February 14, 2013Applicant: MITSUBISHI GAS CHEMICAL COMPANY, INC.Inventors: Sachiko Arie, Masaki Sugita
