  • Patent number: 8342120
    Abstract: A system that incorporates teachings of the present disclosure may include, for example, an apparatus having a tube with an ingress opening to receive a liquid, and an egress opening to release the liquid, a conductor positioned in a conduit of the tube, the conductor and the conduit having dimensions to cause a surface tension of the liquid to prevent a constant flow of the liquid from the egress opening, and a power supply coupled to the conductor to apply a charge to the liquid to overcome the surface tension and form at the egress opening a single jet stream of the liquid applicable on a substrate to create a pattern. The single jet stream can be controllable in part by a viscosity of the liquid. Additional embodiments are disclosed.

  • Patent number: 8322301
    Abstract: An intermediate reserve tank for temporarily storing a conductive coating medium is provided in a coating medium supply passage for supplying the conductive coating medium from a color switch valve mechanism to a spray gun. A block valve mechanism for electrically insulating the color switch valve mechanism and the intermediate reserve tank is provided. A coating medium extrusion portion for supplying water or a cleaning solution is connected to a transmission passage between the intermediate reserve tank and the spray gun via a switch valve. When an amount of the coating medium necessary until an end of a coating operation becomes a predetermined amount, the conductive coating medium is extruded by the water or the cleaning solution by switching the switch valve.

  • Patent number: 8307780
    Abstract: Intended is to enable an electrostatic coating apparatus including a plurality of needle electrodes formed in an annular shape and having a blot preventing function, to prevent the generation of a spark discharge reliably, in case an arbitrary needle electrode approaches an earth element, and to keep the intensity of a generated electrostatic field properly. A coating gun comprises a blot preventing device including a ring-shaped electrode unit having a plurality of needle electrodes protruding radially at a substantially equal spacing radially outward from an annular base member, and a high-voltage generator for applying a high voltage to the electrode unit. The needle electrodes are connected in parallel with the high-voltage generator through individual resistors, block-by-block resistors and built-in resistors.

  • Patent number: 8309184
    Abstract: The invention relates to a method for priming a substrate by contacting the substrate with a primer fed from a primer source and depositing the primer on the substrate. Compared to other priming methods, the claimed priming gives better results because the deposition is carried out electrostatically.

  • Patent number: 8276539
    Abstract: An observation sample is prepared by immobilizing a nanomaterial on a substrate 10 by applying a voltage between a nanomaterial dispersion liquid 13, filled in an interior of an electrostatic spray nozzle 20, and the observation substrate 10 to electrostatically spray and dry the dispersion liquid 13 and electrostatically deposit the nanomaterial. With respect to the observation substrate 10, including a conductive grid portion 11 and a supporting film 12, a reference electrode 81 is disposed below the substrate 10 and a bias voltage of the same polarity as the electrostatic spraying voltage is applied to the grid portion 11 of the substrate 10 to adjust immobilization positions of the nanomaterial on the substrate 10. An observation sample, with which the nanomaterial is immobilized in a satisfactory state on the substrate, can thereby be prepared.

  • Patent number: 8272345
    Abstract: An electrohydrodynamic spraying or spinning deposition system, which includes a common source of pressurized liquid within a manifold, and an array of 2 or more spraying tips, each tip being fed from the common source of pressurized liquid to create a liquid flow path. An individual flow impedance device is disposed within each tip's individual liquid flow path from the pressurized liquid source into each spraying tip. The individual flow impedance devices are disposed within a replaceable sheet, which can be easily cleaned or changed to accommodate the instance liquid viscosity and composition. A high voltage source is applied to create a high voltage potential applied between the tip array and a deposition surface.

  • Patent number: 8225740
    Abstract: An arm of a coating robot is used to prevent external leakage of a high voltage. A tank is installed on a robotic arm and contains water as an actuating liquid. The water is supplied to a paint cartridge by a pump controlled by a controller. The water sent from the pump under pressure is supplied to the paint cartridge by a conduit tube. A high voltage generator and a bleeder resistor are combined with the tank such that a high voltage generated by the high voltage generator is supplied to the electrostatic paint applicator via the water. For replenishment of water to the tank is attained by relatively connecting a nozzle in communication with a water source to a main pipe. While the high voltage generator generates a high voltage, the nozzle and the main pipe are kept disconnected to maintain electrical insulation between the nozzle and the main pipe.

    Abstract: A method and apparatus for electrostatic spray deposition (ESD) for fabricating a thin-layer yttria-stabilized zirconia (YSZ) electrolyte on a solid oxide fuel cell (SOFC) anode substrate constructed of nickel-YSZ cermet. By reducing the thickness of the electrolyte, and thereby reducing the cell internal IR drop, an intermediate temperature SOFC (ITSOFC) can operate at 600-800° C. A collar positioned at a distance from a discharge end of a spray nozzle enhances a spray pattern of a precursor including the electrolyte material and thus provides a very thin electrolyte layer.
