Publication number: 20150192568Abstract: A method for easily and non-invasively determining a degree of stratification and/or differentiation of cultured cells, and an apparatus for determining a degree of stratification and/or differentiation of cultured cells are provided. The invention relates to a method for determining a degree of stratification and/or differentiation of cultured cells, including: (a) a harvesting step of harvesting a culture solution of the cultured cells; (b) an analytical step of analyzing at least one type of a metabolite of the pentose phosphate pathway and/or the TCA cycle in the culture solution; and (c) a determination step of referring to a database of correlations between prospectively-obtained degrees of stratification and/or differentiation of the cultured cells and analytical results of metabolites, for analytical results obtained in the analytical step, to determine the degree of stratification and/or differentiation of the cultured cells.Type: ApplicationFiled: July 17, 2013Publication date: July 9, 2015Applicant: HITACHI, LTD.Inventors: Keisuke Shibuya, Ryoichi Haga, Masaru Namba, Ryota Nakajima

Publication number: 20140178996Abstract: This invention provides a culture control method and a cell culture apparatus that enable stable cell culture by regulating shear stress to be applied to cells within an adequate range. With the application of such culture control method and cell culture apparatus, cell culture is performed under agitation culture conditions in which the shear stress distribution is 0.5 Pa to 20 Pa in 80% or more of the culture vessel by volume.Type: ApplicationFiled: December 17, 2013Publication date: June 26, 2014Applicant: HITACHI, LTD.Inventors: Keisuke SHIBUYA, Ryoichi HAGA, Masaru NAMBA, Kenichiro OKA, Ken AMANO

Publication number: 20140041472Abstract: A transmission includes an input shaft for receiving rotation of an engine, an intermediate shaft connected to the input shaft via a damping mechanism, drive gears, driven gears, and an output shaft. Rotation of the input shaft is transmitted to the driven gears, which are inserted into the output shaft to be free to rotate, via the damping mechanism, the intermediate shaft, and the drive gears. A gear shift is performed by fixing one of the driven gears to the output shaft to be incapable of relative rotation using a selector mechanism. An impact generated when the gear is fixed is absorbed and dampened by the damping mechanism, which is interposed between the input shaft and the intermediate shaft.Type: ApplicationFiled: July 22, 2013Publication date: February 13, 2014Applicant: Fuji Jukogyo Kabushiki KaishaInventors: Yasuyuki Ukon, Keisuke Shibuya
