  • Patent number: 10391571
    Abstract: A controller for controlling a wire electric discharge machine is configured to monitor the remaining lifetime of a wire electrode and calculates an electric discharge machining time, thereby determining the timing of replacement of the wire electrode, so that it can recognize the timing of interruption of electric discharge machining. Consequently, a program operation can be suspended and the wire electrode can be cut and automatically replaced at that timing. After the replacement of the wire electrode, moreover, the wire electrode can be connected and the program operation can be restarted.

  • Patent number: 9309601
    Abstract: The methods, systems, and apparatus disclosed herein employ natural, common salts, that are electrochemically activated (ECA) in an aqueous solution to result in an ECA product solution that is safe and non-toxic. Various implementations include a portable table top design having a portable receptacle that includes electrodes. The receptacle fits on a base which provides power for the electrochemical activation. Continuous flow designs receive input water, mix the water with reactants then pass the solution between electrodes to electrochemically activate the solution. Using a metal halide salt, such as NaCl with citric acid may produce a sanitizer or disinfectant. Using a metal carbonate salt, such as K2CO3, as the reactant may result in a cleaning or degreasing solution. Another implementation is that of an immersion wand that can be placed in a reservoir to produce the ECA product solution.

  • Patent number: 8197658
    Abstract: In order to solve various problems such as a reduction in a paint resin with the progress of electrodeposition coating treatment and remelting of a coating film or the occurrence of pinholes caused by an increased concentration of an electrolyte as a result of the reduction, upsizing of a hollow electrode with a membrane for electrodeposition coating combined with a barrier membrane (e.g., an ion exchange membrane) and an increase in the number of components should be avoided. In order to realize this, a barrier membrane 20 such as an ion exchange membrane is attached to the exterior surface of an electrode main body 10, which is in a hollow state made of a conductive material and configured so as to allow a liquid to pass through freely between the inside and outside of the electrode serving as a support.

  • Publication number: 20120043217
    Abstract: An electroplating/etch apparatus including a fluid jet and a dryer present over the tank containing the electrolyte for the electroplating/etch process. The fluid jet and the dryer remove excess liquids, such as electrolyte, from the component being plated or etched, e.g., working electrode. The working electrode is present on a holder that traverses from a first position within the tank during a plating or etch operation to a second position that is outside the containing the plating electrolyte. The fluid jet rinses the working electrode when the holder is in the second position, and the forced air dryer blows any remaining fluid from the fluid jet and the electrolyte from the working electrode into the tank.

  • Patent number: 8012330
    Abstract: A plating method, employing a face-down manner of plating and using a resistor body between a substrate and an anode, can securely bring an entire surface to be plated of the substrate into contact with a plating solution without permitting intrusion of air bubbles to the surface to be plated. A resistor body is disposed above the anode and immersed in the plating solution, allowing the plating solution to flow along an upper surface of the resistor body from the periphery toward the center of the resistor body. Thus, a raised portion of the plating solution is created in the center of the upper surface of the resistor body. The substrate is then lowered with the surface facing downwardly so as to fill the space between the surface to be plated of the substrate and the upper surface of the resistor body with the plating solution.
