  • Patent number: 11453686
    Abstract: The present invention aims to provide a (meth)acrylic-modified silicone macromonomer, which may be used as a raw material for a (meth)acrylic copolymer capable of forming a coating having excellent antifouling properties and surface smoothness. A (meth)acrylic-modified silicone macromonomer of formula (b1) is provided, which has 1 to 80 branches attached to a linear polysiloxane backbone and the branch has a (poly)oxyalkylene structure of the formula —(CaH2aO)b— and a (meth)acryloyl group at a terminal. The (meth)acrylic-modified silicone macromonomer is a raw material for a polymer used in an antifouling paint.

  • Patent number: 7454124
    Abstract: For a plurality of digital video signals whose frame frequencies are different, a pixel number converting circuit to convert the number of pixels is provided so that differences of the frame frequencies are replaced to differences of the numbers of pixels and a plurality of digital video signals whose frame frequencies are different can be processed by a common clock frequency. The frame frequency is detected by a frame frequency value decoder and the number of pixels in the horizontal direction of the pixel number converting circuit is properly set in accordance with the frame frequency. As mentioned above, if the differences of the frame frequencies are replaced to the differences of the numbers of pixels and the images are converted into the image in which the frame frequencies are the same and the numbers of pixels are different, the frame frequencies are equalized and the signals can be processed by the same clock.
