Abstract:
A method for producing a substrate having a carbon-doped titanium oxide layer, which is excellent in durability (high hardness, scratch resistance, wear resistance, chemical resistance, heat resistance) and functions as a visible light responding photocatalyst, is provided. The surface of a substrate, which has at least a surface layer comprising titanium, a titanium alloy, a titanium alloy oxide, or titanium oxide, is heat-treated in a combustion gas atmosphere of a gas consisting essentially of a hydrocarbon, or in a gas atmosphere consisting essentially of a hydrocarbon, such that the surface temperature of the substrate is 900 to 1,500° C.; or a combustion flame of a gas consisting essentially of a hydrocarbon, is directly struck against the surface of the substrate for heat treatment such that the surface temperature of the substrate is 900 to 1,500° C., thereby forming a carbon-doped titanium oxide layer, whereby the substrate having the carbon-doped titanium oxide layer is obtained.

A sheet comprising thermoplastic polymer (TP) and short high tensile modulus fibers, in which the concentration of TP in the middle of the sheet is higher than at the surface of the sheet, useful for making prepregs with a thermoset resin.
Abstract:
A method of forming an insulating film includes forming a base film comprising a material whose surface is oxidized by being exposed to an oxidant. A source gas containing a metal material and a first oxidant having a first oxidation force are alternately supplied to form a first insulating film on the base film. A source gas containing a metal material and a second oxidant having a second oxidation force stronger than the first oxidation force are alternately supplied to form a second insulating film on the first insulating film.
Abstract:
Methods for combining conductive filled low surface energy substrates, such as but not limited to polyolefins, and flame applied nitrogen based coupling agents are described. The methods include adding a conductive material to a surface and or matrix of the thermoplastic substrate so as to form a conductive thermoplastic substrate and a flame applied nitrogen-based coupling agent to form functional groups on the conductive thermoplastic substrate. The methods provide improved paint transfer efficiency, paint coverage, and adhesion durability characteristics. The methods are especially suitable for paintable automotive components, such as but not limited to exterior body panels, fascias, and the like.
Abstract:
An inkjet printhead is provided comprising ink drop generators formed in a substrate at a density of greater than approximately ten ink drop generators per square millimeter of the substrate and ink channels formed in the substrate for supplying ink to ink drop generators. The ink drop generators are arranged in approximately parallel rows. The ink channels are arranged to supply ink to the rows of ink drop generators. The ink drop generators in each row are arranged in a plurality of groups, with each group in fluid communication with a respective ink supply channel.
Abstract:
An inkjet printhead IC is fabricated using a wafer substrate that defines a plurality of ink inlet channels. A plurality of nozzle structures fabricated on the substrate to define nozzle chambers are in fluid communication with the ink inlet channels and an ink ejection nozzle in fluid communication with each nozzle chamber. Each nozzle structure has a chamber, an ejection nozzle in fluid communication with the chamber, and an ejection member for acting on ink within the chamber. A plurality of actuators attached to the substrate move each of the ejection members respectively, the movement being substantially parallel to the ink inlet flow direction; such that, ink is ejected through the ejection nozzle upon activation of the actuator corresponding to that nozzle structure.
Abstract:
Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol of polymer solution to a substrate and substantially simultaneously applying an energy source to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.
Abstract:
A process for forming curable powder comprises providing an aqueous dispersion of particles of curable resin and optionally particles comprising at least one curing agent; aggregating the particles optionally with the curing agent to form aggregated particles; coalescing the aggregated particles to form fused particles; and removing the fused particles from the aqueous dispersion. By the process, a curable powder is formed. The curable powder may be used in powder coating.
Abstract:
An ink jet printhead chip includes a substrate that defines a plurality of ink inlet channels. A plurality of nozzles is positioned on the substrate and is in fluid communication with the ink inlet channels. A plurality of elongate micro-electromechanical actuators is fast with the substrate at one end, an opposed end being displaceable relative to the substrate on receipt of an electrical drive signal. Each opposed end is operative on a respective nozzle to eject ink from the nozzle. Control circuitry and drive circuitry for each actuator is positioned on the substrate and interposed between the actuator and the substrate.
