Abstract:
The invention provides a waterproof self-luminescent spray-painted film with a thickness of 0.150-1.560 mm. The film has, from top to bottom, ink reception layer (1), connection layer (2) and light-storing photo-luminescent film (3); wherein the ink reception layer (1) is prepared by mixing inorganic filler, adhesive, color fixing agent, coupling agent, surfactant, cross-linking agent, fluorescent whitening agent and water at a ratio. The film has good waterproof property, rapid ink-drying, clear image after being ink-jet printed, and high color density. The film is self-luminescent after absorbing external visible light, and is visible and has the illumination function of low lighting intensity in darkness after a pattern or character is printed on the surface of the film. The film can be widely used in various occasions, such as home decoration, hotels, corridors, office buildings, cinemas, warehouses, ship cabins, underpasses and the places in need of large scale printing and high-precision patterns.

For example, a manufacturing device is discussed that includes a hopper/wiper device operable to apply layers of material to a bed, and heater means operable to heat selected areas of each layer to form a product. The hopper/wiper device is operable so that the product includes at least a first part of a first material or material blend and a second part of a second material or material blend.
Abstract:
The invention relates to a method for applying fluids, especially particle material, on a area that is to be coated, wherein the fluid is applied on the area to be coated in front of a blade when observed from the direction of forward movement of the blade and said blade is then displaced on the applied fluid. The method is characterized in that the blade performs an oscillation similar to a rotational movement.
Abstract:
A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a paste-like mixture of a ceramic composition comprising ceramic powders and nano-sized ceramic materials in a binder is applied to the surface area of the component, and is optionally smoothed using mechanical means. The composition is then allowed to dry and cure to form a dried coating having polymeric characteristics. Upon subsequent heating, the dried coating reacts to produce a glassy ceramic repair coating. Due to the thixotropic properties of the coating composition upon application to a component, the repair method can be performed in-situ while the component remains installed in its operating environment.
Abstract:
A method and apparatus for precisely applying radioactive material to a substrate such as a brachytherapy device is disclosed. A radioactive fluid adapted to cure rapidly is deposited as discrete dots onto a surface with a fluid-jet printhead. The apparatus comprises a fluid-jet printhead in communication with a chamber containing radioactive fluid to be applied by the printhead. The printhead is microprocessor driven, and the microprocessor may be provided with feedback from a station where the radioactivity deposited on a preceding substrate in a batch is measured, permitting the system to be recalibrated on an ongoing basis as the batch of printed devices is produced. Compensation for attenuation of radiation by a casing may also be made part of the feedback technique. Also disclosed is a brachytherapy device having printed on a surface dots of radiation-emitting material, in a pattern comprising various bands, dots or areas. Fluids suitable for printing by a fluid-jet printhead comprise a binder such as an acrylic resin or silicate, and a radioactive salt, compound or complex, dissolved in a radiation resistant solvent. Alternative fluids comprise radioactive salts, compounds, or complexes adsorbed onto a microparticulate carrier, or elemental microparticles, dispersed in a rapidly curable radiation-resistant fluid medium.
Abstract:
Smoothing surfaces of a substrate having a profile and irregular surfaces. According to one embodiment, a layer of fill material is applied to at least one surface of the substrate, wherein the fill material fills irregularities in the at least one surface. The layer of fill material is scraped from the at least one surface to provide a relatively smooth at least one surface.
Abstract:
A plastic container comprises a lower base-forming portion that includes a plurality of circumferentially-spaced, generally spherically-shaped segments and a plurality of intervening, circumferentially-spaced, totally convex, hollow foot-forming portions that extend radially from the central bottom portion and downwardly from the spherically-shaped segments to form a clearance for the central bottom portion. The clearance-forming portion of each foot-forming bottom portion includes a compound curved offset formed with opposing radii of curvature of a substantial fraction of an inch, the compound curved offset curving downwardly and outwardly about a center of curvature below the bottom-forming portion before curving about a center of curvature above the bottom-forming portion. Each bottom clearance-forming portion further includes a spherical surface curving downwardly and outwardly from the central bottom portion and member into the compound curved offset and a lowermost substantially planar portion extending downwardly and outwardly from the compound curved offset for formation of one of the supporting feel.
Abstract:
A silicon/silicon carbide material which eliminates contamination by outgassing and direct contact is described as well as wafer processing parts made of this material and wafer processing methods using the silicon/silicon carbide material. An ultraclean silicon/silicon carbide material may be formed by first forming a Si/SiC part by prior art methods. The Si/SiC part then is subjected to a temperature sufficient to cause the impurities within the silicon carbide to either react and/or diffuse into the silicon fill. The contaminated silicon fill is then removed, either by high temperature evaporation or by a chemical etch. Clean silicon is then impregnated within the pore space of the silicon carbide part. The part which results has ultraclean silicon and silicon carbide grains which have most, if not all, of the impurities removed from the surface of the grains. Thus, an ultraclean material results which will not outgas or directly contaminate silicon wafers.

The process permits applying a fluorocarbonated resin base coating on a flat metallic support (4). According to the invention, this coating is applied in a continuous manner, directly on the support (4) by serigraphy. Use particularly to coat cooking utensils with a layer of fluorocarbonated resin. (See FIG. 2).
Abstract:
A coating method and apparatus which enables high-speed coating with a minimum of defects such as streaks including cases where the surface tension of the coating solution is relatively high. The method includes the following steps: applying an excess amount of a cleaning fluid to the substrate; scraping off the cleaning fluid at a first scraping section; applying an excess amount of the coating solution to the substrate while a remaining portion of the cleaning fluid remaining on the substrate is in an undried state; and scraping off a surface-side portion of the coating solution at a second scraping section, thereby metering the amount of the coating solution to be applied. In addition, a similar object is attained by a coating method wherein, in the aforementioned coating method, the organic solvent has a viscosity of not more than 10 cp, and in a case where the surface tension of the cleaning fluid is .sigma.c (dyne/cm) and the surface tension of the coating solution is .sigma.l (dyne/cm), the surface tension of the cleaning fluid satisfies the relation .sigma.l-7.ltoreq..sigma.c .ltoreq..sigma.l.
