Abstract: A spark plug capable of removing the remaining electric charges is proposed. The spark plug can be installed in a vehicle and has an insulating body, a center electrode, a conductive housing and a conductive wire. The center electrode is passed through the insulating body. The conductive housing is disposed outside the insulating body. One end of the conductive wire is connected to the conductive housing and the other end of the conductive wire is fixed on a negative electrode of a battery of the vehicle. Since the electric charges remaining in the spark plug can be removed by the conductive wire after the high-voltage current sent from the ignition system induces the sparks, the present invention can avoid the damage of the spark plug to keep the spark plug in good status, maintain the efficiency of the engine, and make the car safer in usage.

Abstract: An electroplating apparatus includes a cathode structure, an anode structure, a power supply, and a pressurized electrolyte source. The cathode structure is configured to engage a perimeter portion of a workpiece such as a semiconductor wafer, and the anode structure includes an outlet. The power supply is coupled between the cathode structure and the anode structure. The pressurized electrolyte source is coupled to the anode structure to provide an electrically continuous fluid jet of an electrolyte from the outlet to be directed to a surface of the workpiece that is to be electroplated. A method for electroplating a workpiece includes electrically engaging a perimeter portion of the workpiece with a cathode structure, and directing an electrically continuous fluid jet of electrolyte having positively charged ions towards a surface of the workpiece that is to be electroplated. Preferably, there is a mechanism for providing relative motion between the workpiece and the jet of electrolytes, such as a mechanism for moving the electrically continuous fluid jet of electrolyte to a number of radial positions as the workpiece is rotated around an axis of rotation.
