  • Patent number: 6726964
    Abstract: A process for depositing metal on microparticulate comprising immersing microparticulate in an autocatalytic plating bath comprising the metal; inducing ultrasonic vibration in the plating bath at a frequency corresponding to resonance frequency of the microparticulate; and inducing a turbulent vibration signal in the plating bath in a direction non-parallel to the ultrasonic vibration. This process results in the autocatalytic plating bath depositing the metal on the microparticulate with uniform thickness. The microparticulate can be spheres, flakes or microfibers, and can be made from a number of materials, such as synthetic polymers (nylon, Kevlar™, Zylon™, and aramid fibers) and biodegradable compounds. A method is disclosed for coating a surface with metallized microparticulate fibers with an orientation perpendicular to the surface.

  • Publication number: 20040071862
    Abstract: Materials and methods inhibit the localized build-up of material with respect to certain additive manufacturing processes, including those based on ultrasonic consolidation. Where an object is fabricated by consolidating material increments from a feedstock in accordance with a description of the object, the invention prevents the consolidation in specified regions to provide for an intrinsic support or to otherwise build a part or component in accordance with the description. The object being fabricated, the feedstock, or both, may be treated so as to inhibit the consolidation of material increments in the localized area. That is, such treatment may affect the surface chemistry of the feedstock to prevent local bonding, or the treatment may be applied to a previously built surface of the object.

  • Publication number: 20020155231
    Abstract: The invention provides a method for generating droplets. Extremely fine droplets may be generated (on the order of 1 picoliter or less) using focused acoustic energy to eject the droplets from a reservoir containing two or more immiscible fluids. The droplets may include immiscible fluids or a single fluid. Typically, the droplets are ejected onto discrete sites on a substrate surface so as to form an array thereon. In some instances, the reservoirs contain layers of immiscible fluids, wherein an upper layer exhibits a nonuniform thickness. In such a case, fluid from a lower fluid layer may be propelled through an aperture region of the upper layer.

  • Patent number: 6468605
    Abstract: A deposition process for coating a substrate with an ultrasonically generated aerosol spray of a pseudocapacitive material, or a precursor thereof, contacted to a substrate heated to a temperature to instantaneously solidify the pseudocapacitive material or convert the precursor to a solidified pseudocapacitive metal compound, is described. The ultrasonic aerosol droplets are much smaller in size than those produced by conventional processes and the heated substrate minimizes the possibility of contamination, thereby providing the present coating having an increased surface area. When the coated substrate is an electrode in a capacitor, a greater surface area results in an increased electrode capacitance.

  • Publication number: 20020136844
    Abstract: A method for fabricating a plated product with a basecoat layer, a metal plating layer, and a topcoat layer that are formed on a surface of a base is provided. The method includes the step of forming the basecoat layer and the metal plating layer on the surface of the base. The step is followed by subjecting the metal plating layer to a cold heat treatment or an ultrasonic wave treatment, thus forming a microcrack in the metal plating layer. Afterwards, the topcoat layer is formed on the surface of the metal plating layer.

  • Patent number: 6444255
    Abstract: An electrode substrate is brush cleaned with a hydrogen gas dissolved water, which has an oxidation-reduction potential of −860 mV to −400 mV and a pH of 8 to 12, before applying an alignment layer material on the electrode substrate. Thus, it is possible to decrease the manufacturing costs without decreasing the detergency.

  • Patent number: 6395344
    Abstract: The present invention relates to a method for carrying out a magnesium oxide based deposition on the dielectric surface of a glass plate of a display panel. The method includes the creation of a mist from a metalorganic compound of magnesium dissolved in a solvent, the conveying of the mist to the dielectric surface of the plate, the evaporation the solvent when approaching the dielectric surface of the plate which is taken to a temperature of about 380° to 430°, and the pyrolysis of the metalorganic compound leading to the magnesium oxide based deposit on the surface of the plate and the evaporation of the organic radical of the compound, this deposit being practically waterproof. The method is especially useful in the manufacture of plasma panels.

  • Publication number: 20020058412
    Abstract: The present invention includes a step of forming an Ni bump by non-electrolytic plating in an opening of a protecting film having an insulating property formed on an electrode pad which is provided on a semiconductor substrate, and a step of removing a plating solution residue remaining in a gap between the Ni bump and the protecting film. The plating solution residue is removed by cleaning in a cleaning solution containing hydrogen peroxide, or by applying an ultrasonic wave in a cleaning solution such as pure water.
