  • Patent number: 6239051
    Abstract: The present invention provides a magnesia-spinel refractory in which corrosion resistance and slag penetration resistance are significantly improved. The magnesia-spinel refractory is obtained by mixing magnesia granulated powder having a particle diameter of 10 to 150 &mgr;m and alumina powder having a particle diameter of 0.1 to 5 &mgr;m, molding the resultant mixture, and then burning the molded product to form a dense and strong combined structure of periclase and spinel. The mixture of magnesia and alumina contains powders of both components, or a powder of one of the components and a granulated powder of the other component. It is preferable to use a spray dryer method as granulating means, and a hydrostatic pressing method as molding means. These mixtures are used for producing magnesia-spinel protecting tube and crucible, bricks for copper smelting and converting furnaces, and magnesia-spinel protecting tube and crucible for copper smelting and converting furnace slag.

  • Patent number: 5360411
    Abstract: A liquid medicine injecting device for constantly feeding a liquid medicine into a human body at a certain degree. The liquid medicine stored in a liquid medicine receiving portion is fed out therefrom by a pressure means to be supplied into the human body through a flow amount control means and a human body fitting tool such as a needle. Even if there are contaminant and the like in the liquid medicine or if the flow amount control means is folded, twisted, or pressured, the tube is not blocked up to thereby function as a capillary tube and a member for controlling flow amount with a simple structure so that a high productivity and a easy handling can be obtained.
