  • Patent number: 5146133
    Abstract: An electron gun for a color cathode ray tube having a structure that a plate electrode to be provided within the focusing electrode is given the structure adding the external portion and providing in parallel three elliptical apertures in place of providing the cutout portion at the external portion, a plate electrode to be provided within the acceleration electrode is given the structure providing the cutout portion at the external portion and the vertical axis including the center of external elliptical portion is arranged outside the center axis when the side electron beam enters the main lens is capable of correcting astigmatism and satisfying static convergence. Moreover, rotation and deformation of plate electrode during assembling of electrode can be prevented by providing the straight line portion to the side beam apertures, aberration of lens to be generated at the main lens portion can be reduced and focus characteristic can also be stablized.

  • Patent number: 4851741
    Abstract: An electron gun for color picture tube wherein a focusing electrode adjacent to an acceleration electrode supplied with highest voltage includes two members comprising a first member and a second member, wherein a platelike correction electrode extended into the inside of the first member through a single opening formed in an end face of the first member opposed to the second member is so disposed above and below electron beam passage holes formed in an end face of the second member located at the opposite side with respect to the accelerating electrode and opposed to the first member as to be electrically in contact with the second member, wherein constant voltage is applied to the first member, and wherein voltage so changed in synchronism with electron beam deflection as to have a value increased with increase in the amount of deflection is applied to the second member.

  • Patent number: 4782890
    Abstract: A heat pipe comprising a container having water enclosed therein as a working fluid and made of a material reactive with water to evolve hydrogen gas. The heat pipe is characterized in that the container has placed therein a solid oxidizing agent for oxidizing the hydrogen gas to water. The hydrogen gas produced by the reaction of the working fluid, i.e. water, with the container is oxidized to water by the oxidizing agent without remaining in the form of a gas within the condensing portion of the pipe.

  • Patent number: 4760878
    Abstract: A process for producing a heat pipe including the steps of treating the inner surface of a steel container with an aqueous solution of a vanadate with heating, and enclosing in the container a working liquid prepared by adding an alkalinizing pH adjusting agent to pure water and having an adjusted pH of 8 to 12. When the container inner surface is treated with the aqueous vanadate solution with heating, a protective layer covering the inner surface is formed. The working liquid, when in the range of 8 to 12 in pH, maintains the protective layer in a stable state over a prolonged period of time.
