  • Patent number: 6802430
    Abstract: A fuel tank and a fuel-filler tube, which maintain excellent corrosion-resistance over a long term even in a severely corrosive atmosphere, is made of a ferritic stainless steel sheet good of formability. The steel sheet, which has elongation of 30% or more after fracture by a uniaxial tensile test and minimum Lankford value (value-rmin) of 1.3 or more, is formed to a product shape, and paint is cathodically electrodeposited on a surface of the formed stainless steel sheet. The stainless steel sheet may be one coated with an Al or Zn plating layer. When the fuel tank or fuel-filler tube is fabricated by welding, Zn-rich paint is preferably applied to a welded part in prior to cathodic electrodeposition coating.

  • Patent number: 6797410
    Abstract: A steel composition, in which, Si content is regulated to a given range and Nb and Cu or Ni, Mo are compositively added, and a recrystallization annealing is carried out to form an internal oxide layer just beneath a surface of a steel sheet and a surface oxide simultaneously formed on the surface of the steel sheet is removed by pickling. As a result, the formation of oxides of Si, Mn and the like is considerably decreased on the surface of the steel sheet in a subsequent heating before plating because the above internal oxide layer acts as a diffusion barrier. Thus, there can be obtained high tensile strength hot-dipped steel sheets having a considerably excellent plating property.

    Abstract: In the formation of through wirings in a silicon substrate and so forth, there was a need for the development of a technology that would allow metal to be reliably filled particularly in the vicinity of openings of through holes and other fine holes. This invention provides a metal filling method and member with filled metal sections in which, in the inflow and filling of a plating solution into through holes 11 of a substrate 10 by immersing said substrate 10 in heated and melted conductive metal, filled metal sections are formed by preliminarily forming a metal layer 15 on the inner surface of one of the ends of through holes 11 of this substrate 10 as well as on substrate top surface 13 around those openings, removing substrate 10 on which inflow and filling of the plating solution into through holes 11 has been completed from the plating solution, and then cooling to solidify the plating solution that has been filled into the through holes.

  • Patent number: 6555157
    Abstract: Methods of coating an implantable device and a system for performing such methods are disclosed. An embodiment of the method includes applying a coating substance to the surface of an implantable device, and rotating the implantable device in a centrifuge. The method can uniformly coat the implantable device with the coating substance and to remove unwanted accumulations of coating substance entrained between struts or crevices in the implantable device body. This system is applicable to methods for coating intraluminal stents, synthetic grafts, and stent coverings with therapeutic compositions comprising therapeutic agents mixed with a polymeric matrix and a solvent.

  • Patent number: 6555239
    Abstract: A composition and method is described for providing conformal protective or decorative polymer coatings on metals such as aluminum, copper, iron, steel, zinc, and their by dip autopolymerization. In accordance with the present invention, an acidic solution of organic monomer undergoes autopolymerization upon contact with a metal substrate, thereby forming a polymeric coating on the substrate. The method comprises providing the acidic monomer solution, dipping the metal substrate to be coated for a prescribed period of time depending on the thickness of the coating desired, and then removing the substrate from the solution. Importantly, the polymerization requires no application of external driving force, such as thermal or electrical energy. The coatings thus formed are up to 50 microns thick, and conform to the shape of the substrate. These coatings further have uniform thickness, and thermal stability and protective properties.

  • Patent number: 6544582
    Abstract: An apparatus and methods for applying a coating to an implantable device. The implantable device can include depots formed in the outer surface thereof to receive the coating. The coating can include a polymer and a solvent applicable to the surface of the implantable device including the depots. The application of the composition is performed under a pressure, which can reduce the surface tension and/or molecular adhesion force of the composition. The reduced surface tension and/or adhesion force allows gas bubbles within the depots to be removed while the composition is being driven into the depots.

  • Patent number: 6524718
    Abstract: A metallic object, having a metallic substrate of a valve metal or a valve metal alloy inclusive of intermetallic phases, and a thin polyphase oxide coating, is disclosed. The polyphase oxide coating has a metal oxide phase and at least one other organic and/or inorganic phase. The polyphase oxide coating is produced by bringing the metallic substrate into contact with an organic and/or inorganic component to be integrated into the polyphase oxide coating such that the inorganic and/or organic phases are present at or in the direct vicinity of the substrate surface and by simultaneously or subsequently anodically polarizing the substrate material in an electrolytic solution.

  • Patent number: 6485778
    Abstract: A method and apparatus for achieving a level exposed surface of an adhesive material pool for applying the adhesive material to lead fingers of a lead frame by contacting the lead fingers with the adhesive material pool within an adhesive reservoir. The level adhesive material exposed surface is achieved by attaching a coating stencil having small apertures, such as a screen or a plate with slots, to the adhesive reservoir, such that the only upward outlet for the adhesive material is through the apertures in the coating stencil. The surface tension between walls of the small apertures and the adhesive material flattens out the exposed surface of the adhesive material. This allows a larger area to be printed with a more uniform thickness layer.
