摘要:
A method and apparatus for coating a thin film which comprises supplying an organic solvent-based coating solution onto the surface of a transferring member from which the coating solution is then allowed to come in contact with a film base so that it is applied thereto while the coating solution which has been supplied onto the transferring member is being partially recovered for reuse.
摘要:
A tungsten disulfide metal surface treatment in which the substrate material is prepared through impingement of small blast media particle sizes to create formed pockets in the substrate material approximately matched to the size of the tungsten disulfide particles. A sand blast apparatus having a vibratory bowl with a throttled intake pipe enables small blast media particles to be used to prepare the substrate surface with the formed pockets. A method for forming the tungsten disulfide surface treatment through roughening the substrate surface in a controlled manner is disclosed.

A method of protecting dyes printed on print media against ozonolysis is provided. The method comprises: (a) providing a first reaction product comprising the reaction of a phenylenediamine or derivative thereof (an anti-ozonant) with a silica or silicate; and (b) reacting the first reaction product in the presence of a water-free solvent with silica groups to form a second reaction product. Also provided is the reaction product resulting from the reaction of (1) the anti-ozonant-silica (or silicate) and (2) silica groups on a substrate. The anti-ozonant-silica (or silicate) is covalently attached to the particles of silica in the media and cannot escape or evaporate away. The use of phenylenediamines as anti-ozonants solves the problem of the fading of dyes on porous media by ozone pollution.
摘要:
Water-based chemical indicator inks for ethylene oxide sterilization processes and methods for its use. The chemical indicator ink contains at least one pH indicator dye selected from the group consisting of Bromocresol green, Bromophenol blue, Methyl red, Ethyl orange, and combinations thereof. The pH indicator dye undergoes an irreversible color change when exposed to ethylene oxide vapor in the presence of low-temperature steam, but when exposed to other sterilization processes either does not undergo a color change or undergoes a color change that is different than is obtained when exposed to ethylene oxide.
摘要:
Systems and methods are described for environmental exchange control for a polymer on a wafer surface. An apparatus for controlling an exchange between an environment and a polymer on a surface of a wafer located in the environment includes: a chamber adapted to hold the wafer, define the environment, and maintain the polymer in an adjacent relationship with the environment; and a heater coupled to the chamber. A method for improving performance of a spin-on material includes: forming the spin-on material on a surface of a wafer; then locating the spin-on material in an environment so that said environment is adjacent said spin-on material; and then controlling an exchange between the spin-on material and said environment. The systems and methods provide advantages because inappropriate deprotection is mitigated by careful control of the environmental temperature and environmental species partial pressures (e.g. relative humidity).
摘要:
The present invention provides a method that is capable of crystallizing a very small amount of solution arranged on a substrate at a predetermined position. By ejecting a solution prepared by dissolving a thin film forming material in a solvent using an ink jet method, droplets of the solution are arranged on the substrate. Crystalline nuclei are created in the solution by controlling a partial pressure of a gas made up of the same components as those of the solvent in the vicinity of the droplets immediately after being arranged to, e.g., a value equal to or substantially equal to the saturation vapor pressure. After creation of the crystalline nuclei, the partial pressure of the gas in the vicinity of the droplets is reduced.
摘要:
A method for manufacturing a flexible printed circuit in which a resin solution is applied onto a circuit substrate having a wiring pattern on its surface so as to form a resin cover layer, having the steps of: wetting the surface of the circuit substrate with a solvent which is capable of dissolving the resin; applying the resin solution onto the surface wetted with the solvent; and drying the resin solution to thereby form the resin cover layer. A flexible printed circuit obtained in the manufacturing method.

The present invention relates to an improved substrate for use in detection of fluorescence. More specifically the improved substrate exhibits a supported surface layer of silicon dioxide on a silicon support material, on another solid support material, or on a silicon layer supported on another solid support material. The inventive substrate allows for a significantly higher sensitivity to be obtained when used in fluorescence analysis. The invention also relates to a method of preparing the inventive substrate, which substrate in one embodiment of the invention takes the form of silicon a slide exhibiting an oxidized surface. The invention also relates to the application of the inventive substrate in microarray analysis.
摘要:
The present invention discloses a sucker rod with high resistance to corrosion, to be used preferably in oil wells. Said sucker rod comprises a core of carbon steel, whether alloyed or not, whose surface is coated by a copper base alloy. Said alloy comprises a 50 to 99.9% copper rate. A process for manufacturing said sucker rod is included.
摘要:
In a method for preparing ultra-thin films of carbon-containing materials, particularly thin films of polymer materials. Films with a thickness of 0.5 nullm or less are formed by deposition of the materials from a liquid phase onto a solid surface. The deposition takes place in an enclosure where the materials also are subjected to a post-deposition processing. The total humidity content in the enclosure shall be maintained at a level corresponding to a relative humidity of less than 50% in a volume of air equal to the volume of enclosure by excluding and/or removing water arid water vapor from the materials and/or the atmosphere in the enclosure.
