  • Method of eliminating foam appearing on a liquid surface
    Patent number: 4058481
    Abstract: A method of eliminating liquid foam appearing on the surface of a liquid tent in a reaction vessel is characterized by employing a liquid particle diffusion device with a liquid ejecting nozzle element and a liquid diffusing element for radially diffusing the liquid circulated from the reaction vessel in the form of liquid particles having kinetic energy. The liquid particles hit and break the foam thereby eliminating the foam.

  • Ghost signal suppressing device for television receiver set
    Patent number: 3988775
    Abstract: A ghost signal suppressing device comprises a circuit for suppressing the luminance signal of a ghost signal and a circuit for suppressing the color signal of the ghost signal. A delayed signal used for suppressing the ghost signal is produced at a single delay circuit and branched off to be used for both the suppressing circuits. The branched signals of the same delay time are individually adjusted in their amplitude and then subtracted from an original signal at the respective suppressing circuits.
