  • Patent number: 11455933
    Abstract: 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.

  • Patent number: 10851342
    Abstract: 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.

  • Publication number: 20130011921
    Abstract: 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.

  • Patent number: 4876407
    Abstract: 2,3-Dichlorobutadiene-1,3 is produced by a continuous dehydrochlorination of 1,2,3-trichlorobutene-3 in a water miscible solvent in the presence of an alkali metal hydroxide. An evaporator is connected in the downstream of a reactor for the dehydrochlorination to recover the unreacted 1,2,3-trichlorobutene-3 and said water miscible solvent by an evaporation.
