Publication number: 20210317754Abstract: A housing structure for a rotary machine includes a main body and a heat transfer member. The heat transfer member includes a material having higher thermal conductivity than that of the main body. In addition, the heat transfer member is sandwiched between a first surface and a second surface of the main body while receiving a compressive load from the first surface and the second surface, thereby alleviating temperature distribution that may occur in the main body and reducing thermal deformation.Type: ApplicationFiled: March 16, 2021Publication date: October 14, 2021Inventors: Toshiaki Kokufuda, Ryutaro Fuzisawa, Toshihiro Takeda, Hao Li, Hikaru Kurosaki

Patent number: 8247578Abstract: The present invention provides a process for producing a 3-aralkyloxypyrrolidine derivative which is important for production of pharmaceutical products and the like. In the present invention, a N-protected-3-hydroxypyrrolidine is converted into a N-protected-3-aralkyloxypyrrolidine by allowing an aralkyl halide to act in the presence of a base and at least one of a metal halide and a phase-transfer catalyst followed by deprotecting a N-protecting group to convert it to a 3-aralkyloxypyrrolidine derivative and subsequently treating the derivative in a solvent containing a polar solvent, thereby obtaining the 3-aralkyloxypyrrolidine derivative as a crystal. According to the present invention, a 3-aralkyloxypyrrolidine derivative of high purity can be produced conveniently and efficiently on an industrial scale.Type: GrantFiled: May 25, 2011Date of Patent: August 21, 2012Assignee: Kaneka CorporationInventors: Toshihiro Takeda, Masatoshi Ohnuki

Patent number: 8183413Abstract: Provided is a process for production of a ?-amino-?-hydroxy carboxamide derivative that is important in production of drugs or the like. In the presence of a predetermined solvent, a ?-(N-protected)amino-?-hydroxycarboxylic acid is reacted with an amine to conversion to a ?-(N-protected)amino-?-hydroxy carboxamide derivative; then the derivative is deprotected for conversion to a ?-amino-?-hydroxy carboxamide derivative; and the derivative is crystallized using a protic solvent to obtain a crystal. The high-purity ?-amino-?-hydroxy carboxamide derivative can be stably produced on an industrial scale by the process.Type: GrantFiled: January 16, 2007Date of Patent: May 22, 2012Assignee: Kaneka CorporationInventors: Narumi Kishimoto, Hiroaki Yasukouchi, Toshihiro Takeda
