  • Publication number: 20070125157
    Abstract: In a leak test of an LNG tank by filling water, corrosion is prevented even if corrosive water such as sea water or filthy water is used, and the dissolution of zinc in water is restrained. A zinc-containing paint (18) is applied or a tape having a zinc-containing layer on the surface thereof is affixed to the surface of a weld zone (16, 14) of an inner wall (12) of the LNG tank, and corrosive water including sea water or filthy water is introduced into the LNG tank in the state in which the zinc-containing paint (18) or the zinc-containing layer forms the surface of the weld zone. The LNG tank is filled with the corrosive water, and after a predetermined period of time has elapsed, the corrosive water is discharged from the LNG tank. In the case where the tape having a zinc-containing layer on the surface thereof is affixed, the tape is taken off, and then a flaw in the inner wall of LNG tank is detected.

  • Patent number: 7179094
    Abstract: A surface mount technology connector comprises a housing provided with a plurality of contacts. At least one metal fitting is fixed to a sidewall of the housing. The metal fitting has a base and a soldering section for soldering to a circuit board. The base has a smaller width than the soldering section. The soldering section extends from a substantial center of the base with respect to the width thereof. The soldering section and a portion of the base extend approximately perpendicular to and away from a bottom of the sidewall of the housing. The sidewall of the housing has a solder viewing section at each side of the base. The solder viewing section retracts inward as the solder viewing section approaches the soldering section to expose the soldering section at the bottom of the sidewall of the housing.
