Patent number: 11566680Abstract: Provided is a valve device and a shock absorber that can prevent them from being in a failure state at the normal time and can freely set a passive valve even when both pressure control and passage opening/closing are performed by a solenoid valve. For this reason, the valve device includes a first passage and a second passage connected downstream of the pressure introducing passage, a solenoid valve that opens the first passage to control the upstream pressure and closes the second passage when energized, and that closes the first passage and opens the second passage when not energized, and a passive valve provided downstream of the solenoid valve in the second passage.Type: GrantFiled: March 6, 2019Date of Patent: January 31, 2023Assignee: KYB CorporationInventors: Hidemasa Kato, Ryosuke Kamakura

Patent number: 10851342Abstract: The present invention allows a TET1 protein to be more stably expressed in human pluripotent stem cells than in the past by, inter alia, substituting the second amino acid from the amino terminal of a TET1 protein with a different amino acid. Furthermore, upon differentiation of said pluripotent stem cells, it is possible to quickly eliminate the expression of, inter alia, NANOG, which is an inhibitor of differentiation and promote the expression of factors related to differentiation by introducing a variant TET1 protein to a pluripotent stem cell. The present invention provides a method for manufacturing pluripotent stem cells with increased differentiation potential, and a substance that is useful to said method.Type: GrantFiled: December 14, 2017Date of Patent: December 1, 2020Assignee: Saitama Medical UniversityInventors: Hidemasa Kato, Yosuke Moriyama, Keiko Hiraki, Akihiko Okuda

Patent number: 8606809Abstract: In one aspect of an embodiment, a computer determines an identity of the cells with a cell shape data, and also determines a correspondence relationship of identification data between a plurality of cell analyzing tables at a different observing times. Also, the computer, based on the correspondence relationship of the identification data, records a plurality of cell analyzing tables at the different observing times in a storage medium by making into a database which can be searched in a direction of a time axis for each of the cells having commonality.Type: GrantFiled: April 15, 2010Date of Patent: December 10, 2013Assignee: Nikon CorporationInventors: Hidemasa Kato, Yasujiro Kiyota

Publication number: 20130011921Abstract: Disclosed is a method for producing an iPS cell having a very similar gene expression pattern to that of an ES cell with high efficiency. Specifically disclosed is a method for producing an artificial pluripotent stem cell (an iPS cell), which comprises the steps of: introducing a pluripotency-inducing factor comprising at least an Myc family gene or an Myc family protein into a somatic cell; and culturing the somatic cell in the presence of a sirtuin inhibitor and/or a poly-ADP ribose polymerase (PARP) inhibitor.Type: ApplicationFiled: February 15, 2011Publication date: January 10, 2013Applicant: SAITAMA MEDICAL UNIVERSITYInventors: Tomoaki Hishida, Akihiko Okuda, Hidemasa Kato
