Publication number: 20150024208Abstract: (Problem) A porous carbon material having excellent graphite crystallinity, good carrier mobility and proper porosity, a porous carbon material having edges of carbon hexagonal planes located on outer surfaces of particle and structure, and flaky graphite being similar to graphene are produced. (Means to Solve) By subjecting a carbon material, in which a closed-pore-ratio and an amount of remaining hydrogen in the material are set to be within a proper range, to hot isostatic pressing treatment, a vapor phase growth reaction of graphite is generated in closed pores as nuclei using hydrogen and hydrocarbon generated from the carbon material, thereby producing a large amount of targeted porous carbon material at low cost. Flaky graphite being similar to graphene is produced by applying physical impact to the obtained porous carbon material or by generating a graphite intercalation compound using the porous carbon material as a host and then quickly heating the compound.Type: ApplicationFiled: October 1, 2014Publication date: January 22, 2015Inventors: Kazuo MURAMATSU, Masahiro TOYODA

Patent number: 8618700Abstract: A head of an output shaft of a linear actuator is modified so as to absorb vibrations that may be transmitted between the output shaft and a moving object. A linear actuator has an output shaft with a leading end to which a head is fixed. The head has an O-ring that is fitted thereto, and a part of the O-ring outwardly projects from the head. The O-ring is made of rubber that is softer than the material of the head. The head is contained in a containing space in an attachment, and in this condition, the O-ring contacts an inner circumferential surface of the containing space by deforming.Type: GrantFiled: February 23, 2012Date of Patent: December 31, 2013Assignee: Minebea Co., Ltd.Inventors: Kazuo Muramatsu, Katsutoshi Suzuki
