  • Patent number: 7782994
    Abstract: This invention relates to an inhibitor of lead-induced stress corrosion cracking including nickel boride in the secondary side of steam generator tubes in nuclear power plants and an inhibition method using the same, and more particularly, to an inhibitor of lead-induced stress corrosion cracking, in which nickel boride is added to secondary side cooling water of the steam generator in an amount of 0.2˜6 g/l, and to an inhibition method using the same. According to this invention, when the inhibitor of lead-induced stress corrosion cracking is added to the secondary side of the steam generator tube in nuclear power plants, stress corrosion cracking of the tubes, which occurs in the lead-containing neutral or caustic solution, and a crack growth rate are decreased, thus increasing elongation. Further, a stress corrosion cracking ratio is decreased, and therefore the stress corrosion cracking resistance of metal or alloy can be improved.

  • Patent number: 7560016
    Abstract: To make a metal feature, a non-plateable layer is applied to a workpiece surface and then patterned to form a first plating region and a first non-plating region. Then, metal is deposited on the workpiece to form a raised field region in said first plating region and a recessed region in said first non-plating region. Then, an accelerator film is applied globally on the workpiece. A portion of the accelerator film is selectively removed from the field region, and another portion of the accelerator film remains in the recessed acceleration region. Then, metal is deposited onto the workpiece, and the metal deposits at an accelerated rate in the acceleration region, resulting in a greater thickness of metal in the acceleration region compared to metal in the non-activated field region. Then, metal is completely removed from the field region, thereby forming the metal feature.

  • Publication number: 20090059535
    Abstract: Provided are a cooling device coated with carbon nanotubes and method of manufacturing the same. Carbon nanotubes are dispersively coated on a surface of the cooling device that radiates generated by a predetermined apparatus or component through thermal exchange. Thus, a carbon nanotube structure is formed so that the cooling device can improve in a thermal radiation characteristic and become small-sized. As a result, electronic devices can be downscaled and heat generated by a highly integrated electronic circuit chip can be effectively radiated, thus increasing lifetime and performance of an operating circuit.

  • Patent number: 7494696
    Abstract: It is now feasible to coat metal objects having a substantially unexpanded surface area with a fused plasticized polyvinyl chloride coating uniformly covering and firmly anchored to the metal object. This objective is achieved by providing a metal substrate to be coated with small anchoring apertures which allow the fused coating to firmly anchor and bond onto and around the metal object and a series of leveling apertures which permit for a more uniform drainage of excessive unfused coating material from the metal object before the fusing of the coating thereto.

  • Patent number: 7479305
    Abstract: The problem in forming solderable and bondable layers on printed circuit boards is that the surfaces tarnish after storage of the boards prior to further processing (mounting of the electrical components), thus affecting solderability and bondability. In order to overcome this problem it is suggested to deposit, in a first method step, a first metal which is more noble than copper to the printed circuit board and to plate silver in a second method step with the proviso that the first metal be deposited at a rate that is at most half the rate of silver in the second method step when the first metal is silver.
