  • Patent number: 5865979
    Abstract: The entire outer surface of a ground rod, including its pointed end portion, has a continuous and uniform electroplated coating. The rod has a blunt end portion shaped to minimize mushrooming when it is hammered for driving the rod into the ground. Jets of plating solution directed against the rod produce swirling motion of plating solution around the rod while it moves longitudinally through a plating bath. Uniformity of the plated coating may be enhanced by rotating the rod during longitudinal movement through the plating bath.

  • Patent number: 5783790
    Abstract: A surfactant is added to anodic or cathodic water obtained by electrolyzing deionized water or high-purity water. Then, an object of treatment is treated with the anodic or cathodic water containing the surfactant. The object of treatment may be treated, in this way, while irradiating it with an ultrasonic wave having a frequency between 30 kHz and 3 MHz. Furthermore, the anodic or cathodic water is continuously jetted or dropped onto the object of treatment from a nozzle, while irradiating an ultrasonic wave at least at a part in the feed pipe of the anodic or cathodic water.

  • Patent number: 5681444
    Abstract: Electrical feedthroughs in printed circuit board support substrates for use in making double sided ceramic multilayer printed circuit boards are made by insulating the feedthrough openings with a first layer of nickel oxide and one or more layers of glass, and then filling the remainder of the feedthroughs with a conductive metal via fill ink. After firing, the resultant structure provides insulated electrical feedthroughs through the support substrate.
