Patent number: 11455933Abstract: A circuit device includes a gradation voltage generation circuit, a correction processing circuit, and a driving circuit. The correction processing circuit performs correction processing on input display data to output corrected display data. The driving circuit drives an electro-optical panel by outputting gradation voltages corresponding to the corrected display data based on the gradation voltages. The gradation voltages are grouped into first to k-th groups. At this time, the correction processing circuit determines, by analyzing which group of the first to the k-th groups each input display data belongs to, a number of the input display data belonging to each group, and performs the correction processing based on the determined number.Type: GrantFiled: June 24, 2021Date of Patent: September 27, 2022Assignee: SEIKO EPSON CORPORATIONInventor: Akihiko Okuda

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
