Abstract: A method and apparatus for two-coat one-fire electrophoretic enameling of a work piece made of metal, wherein a first undercoat enamel slip deposit bath is followed by at least one excess slip removing bath before the undercoated work piece is submerged in a process bath including an additive for reducing the electrical resistance of the enamel biscuit followed sequentially by another rinsing bath, a finish enamel coating bath and not less than one final rinsing bath before the coated work piece is subjected to an enamel firing step.

Abstract: A method apparatus is provided for electrophoretically depositing particles onto an electrode, and electrohydrodynamically assembling the particles into crystalline structures. Specifically, the present method and apparatus creates a current flowing through a solution to cause identically charged electrophoretically deposited colloidal particles to attract each other over very large distances (<5 particle diameters) on the surface of electrodes to form two-dimensional colloidal crystals. The attractive force can be created with both DC and AC fields and can modulated by adjusting either the field strength or frequency of the current. Modulating this "lateral attraction" between the particles causes the reversible formation of two-dimensional fluid and crystalline colloidal states on the electrode surface. Further manipulation allows for the formation of two or three-dimensional colloidal crystals, as well as more complex "designed" structures.

Abstract: A metal oxide layer is provided around a thermocouple element. The metal oxide layer is formed by preparing a sol, in which particulates of a metal oxide are dispersed, by a sol-gel method, dipping the thermocouple element in this sol, energizing the thermocouple element as a cathode for bonding the precursor particulates of the metal oxide thereto, and heat treating the same. The thermocouple according to the present invention is compact with a thin insulating layer, excellent in flexibility, and provides no gas adsorption source.

Abstract: A method for manufacturing ink jet printheads and the product printheads derived therefrom. The method involves the electrodeposition passivation of ink channels in ink jet printheads.

Abstract: A method for forming a coating on an electrically conductive surface is discloses. The method comprises the steps of immersing the surface in a bath comprising an electrodepositable mixture of an intrinsically insulative polymer and an organic acid salt of an intrinsically conductive polymer, applying a voltage between an electrode and the surface in the bath to deposit a polymeric coating of the mixture on the surface, and curing the polymeric coating. The polymeric coating can be made electrically conductive by the additional step of immersing the polymeric coating in an organic acid after the deposition and before curing. A multilayered coating can be provided after curing the electrically conductive polymeric coating, by depositing a second or subsequent coating of an electrodepositable organic resin from an aqueous bath containing the resin on application of a voltage between an electrode and the electrically conductive polymeric subcoating in the bath.
