  • Hair cuticle caring method
    Patent number: 6174523
    Abstract: The present invention relates to a hair cuticle caring method or volume enhancing method, which comprises treating hair with a composition containing (A) a cationic surfactant and (B) an organic acid or salt thereof in a combination to give, when an aqueous solution containing 1 mM of each of the components is formed, 40 mN/m or less as the surface tension of the aqueous solution at 27±0.5° C. By the application of the above-described composition, the lift-up of the hair cuticle can be suppressed, the volume can be enhanced softly, moisturized but stickiness-free feeling is imparted and styling ease is improved.

  • CRT Drive circuit comprising white and black level clamping circuitry
    Patent number: 4328514
    Abstract: A CRT drive circuit for amplifying a video signal applied through a video signal transmission cable to a level sufficient to drive a CRT wherein a circuit for clamping the video signal to a white level during the entire period when the cable is disconnected is provided at an input stage, a blanking circuit for clamping the video signal to a black level during a flyback period is provided in an intermediate stage, and a D.C. restore circuit for clamping the black level of the video signal output to a level corresponding to a black level input to the CRT is provided at an output stage. When the cable is disconnected, the entire display area of the CRT screen displays white so that the CRT drive circuit can be readily checked for proper operation.
