  • Patent number: 9745403
    Abstract: To provide a polymer material having properties that allow the polymer material to replace a polyimide and a polyamide synthesized from a petroleum raw material, said polymer material being synthesized from a raw material derived from natural molecules. [Solution] This polymer material is obtained by polymerizing a polymer raw material comprising a dimer of 4-amino cinnamic acid or a dimer of a 4-amino cinnamic acid derivative, which are natural molecules, wherein the carboxyl group is protected by an alkyl chain. The TGA curve of a polyamide acid (PAA-1) and a polyimide (PI-1) according to the present invention is shown in FIG. 5.
    Type: Grant

  • Patent number: 6380944
    Abstract: Image data are defined by color vectors each composed of vector factors. Each vector factor specifies the brightness and color difference of a dot. The image data are transmitted with a normal timing when the vector factors correspond to dots of the image one for one, and are transmitted with another timing in another case to scroll the image horizontally.
