  • UV-curable aqueous emulsion, preparation thereof and solventless coating composition comprising the same
    Patent number: 8114920
    Abstract: The UV-curable aqueous coating composition is characterized by using a UV-curable aqueous emulsion obtained by urethane reaction with a mixture including a poly-carbonate polyol or polyester polyol; an isocyanate compound; a urethane-reactive carboxylic acid; a UV-curable acrylic oligomer having 2 to 9 functional acrylate groups; a UV-curable acrylic monomer; and a urethane-reactive acrylate without an organic solvent. The aqueous composition provides good environmental acceptability and satisfactory film properties comparable to those of the prior oily UV-curable coating composition and, therefore, it is useful for coating various plastics.

  • Device for a compatible luminance/chrominance separation between different standard video signals
    Patent number: 5220413
    Abstract: A preprocessing device of a system that can record and reproduce the luminance and chrominance signal separated from a composite digital VTR signal is disclosed.The luminance/chrominance signal preprocessing device includes an analog/digital converter which samples a NTSC signal inputted as a composite video signal at a certain frequency, and converts the signal sample to a digital signal, a horizontal synchronizing separator that separates the horizontal synchronizing signal from the above NTSC signal, a PLL division that sends a clock signal fixed to the horizontal synchronizing signal outputted from the above horizontal synchronizing separator to the above analog/digital converter, and a luminance and chrominance signal outgoing from the above analog/digital converter is then separated into a luminance signal and a chrominance signal.
