  • Patent number: 5145280
    Abstract: A disaster prevention apparatus is adapted to intercept and disperse gas leaking from a disaster ship offshore. The apparatus includes a marine mover and a water curtain forming device for forming a water curtain on the lee of the disaster ship. Pressurized water is supplied to the water curtain forming device by a water pump. The water thusly supplied is ejected from the water curtain forming device in a direction substantially perpendicular to the water surface, thereby creating a water curtain on the water.

  • Patent number: 4367484
    Abstract: A picture-in-picture color television receiver for simultaneously displaying on a screen a first and a second picture read out from a memory in a state that the second picture is inserted in the first picture, is disclosed. A DC restoration circuit for DC-restoring a color difference signal of the second picture DC-restores a color difference signal of the second picture at the reference level coincident with the reference level of the color difference signal of the first picture, thereby to make the white balance of the first picture coincident with that of the second picture.
