    Abstract: A target material supply apparatus for an extreme ultraviolet (EUV) light source includes a tube that includes a first end, a second end, and a sidewall defined between the first and second ends. At least a portion of an outer surface of the tube includes an electrically insulating material, the first end receives a pressurized target material, and the second end defines an orifice through which the pressurized target material passes to produce a stream of target material droplets. The target material supply apparatus also includes an electrically conductive coating on the outer surface of the tube. The coating is configured to electrically connect the outer surface of the tube to ground to thereby reduce surface charge on the outer surface.

  • Patent number: 8662111
    Abstract: Economical heavy concrete weight coating is used as a weight coating for submarine pipes. The developed economical heavy concrete weight includes steel slag and iron ore as aggregate. Steel slag can contain iron and thus have a higher density than some other types of slag. By supplementing the steel slag with iron ore as aggregate, the economical heavy concrete weight coating can have a higher density than a coating having just slag. Economical heavy concrete weight coating can have a density greater than 190 pcf.

  • Patent number: 8627854
    Abstract: Pressure cast lined steel pipes comprise an annular concrete or mortar liner along an inside diameter, and a metal shell surrounding the liner, wherein the liner is in direct contact with the metal shell. The wall thickness of the liner can be from 10 to 50 times the thickness of the metal shell. The pipe may be coated with a dielectric material. A mold assembly used to form the pipe includes an annular concrete or mortar composition chamber formed between the metal shell and an inner mold member. Pressurized water is used in the mold assembly to pressurize the concrete or mortar composition and exert a desired pressure force onto the metal shell while the composition cures in the mold. Once a desired degree of cure is achieved, the pressure is removed causing the metal shell to exert a desired compression force onto the cured liner.
