  • Patent number: 12006595
    Abstract: The present invention relates to a method for producing a carbon fiber. In the method for producing the carbon fiber, a high pure acrylonitrile monomer with specific contents of impurities and a comonomer are used to produce an acrylonitrile copolymer, and the acrylonitrile copolymer is subjected to a spinning operation, a stretching operation, an oxidation treatment and a carbonization treatment in sequence, for obtaining the carbon fiber. The acrylonitrile copolymer with an appropriate falling-ball viscosity and an appropriate weight-average molecular weight is beneficial to the spinning operation, thereby reducing an inner pore diameter and enhancing strength of the resulted carbon fiber.

  • Patent number: 12003737
    Abstract: Methods and devices for video coding are provided. In the method, the device determines, for a current luma transform block in a coding unit, whether an intra subpartition (ISP) split type is an ISP mode. In response to determining that the intra subpartition split type is not the ISP mode, the device determines a first context index for a Coded Block Flag (CBF) flag of the current luma transform block as being equal to zero or one, where the CBF flag specifies whether the current luma transform block comprises one or more transform coefficient levels not equal to zero. In response to determining that the intra subpartition split type is the ISP mode, the device determines the first context index based on a CBF variable of a previous luma transform unit in the coding unit.
