摘要： The application describes an ink delivery system for an inkjet printer. The system includes a first ink tank operative to supply ink to at least one inkjet printhead and a second ink tank operative to receive ink flown through at least one printhead and not used by at least one printhead. The ink for printing is drawn by low pressure from a first tank through the printhead to a second ink tank. Each of the ink tanks includes a cylindrical tubular segment and a segment with a frustoconical inner section.

摘要： Glass frits and enamel compositions from the glass frits for use in automotive application. The enamel composition includes one or more glass frits with reduced amount of bismuth and/or zinc compared to reference enamel compositions available. The glass frits include one or more transition metal oxides. The glass frits exhibit improved chemical durability, reduced glass density, lower L-value, or optimized optical density for an end user depending on the applications.

摘要： Conductive thick film compositions compatible to aluminum nitride, alumina and silicon nitride substrates for microelectronic circuit application. The conductive thick film composition includes first copper powder, second copper powder, and glass component. The conductive thick film composition further includes CU2O, Ag, and at least one metal element selected from Ti, V, Zr, Mn, Cr, Co, and Sn. After firing, the conductive thick film composition exhibit improved sheet resistivity, and improved adhesion with underlying substrate.

摘要： Modified copper chromite spinel pigments exhibit lower coefficients of thermal expansion than unmodified structures. Three methods exist to modify the pigments: (1) the incorporation of secondary modifiers into the pigment core composition, (2) control of the pigment firing profile, including both the temperature and the soak time, and (3) control of the pigment core composition.

摘要： A method for manufacturing an azoic pigment is disclosed, according to an illustrative embodiment of the present invention. The method includes producing slurry of the azoic pigment. The slurry includes primary aromatic amine (PAA). The method further includes the derivatization of the residual PAA in the slurry, followed by encapsulation of the slurry. The slurry is acidified or basified. Finally, the slurry is further processed, thereby forming PAA migration free azoic pigment. The derivatization and encapsulation additively or synergistically reduce the PAA content thereby inhibiting migration of PAA from the pigment into a substrate onto which the pigment is loaded.

摘要： A multi-layer glass enamel is disclosed. The various layers of the enamel are included to provide certain performance characteristics to the enamel. The components of each layer can be individually adjusted to tailor the performance characteristics influenced by that layer without changing the influence of the remaining layers.

摘要： A fired hybrid enamel coating is provided. The hybrid enamel coating is formed by firing an enamel composition on a substrate. The enamel composition includes at least a first glass frit, which is sintered to form the hybrid enamel coating. The hybrid enamel coating can be cleaned using aqualytic or pyrolytic cleaning methods, and does not discolor or lose gloss when subject to typical pyrolytic cleaning methods. The hybrid enamel coating does not require the application of highly caustic cleaners to remove the baked-on soils
