Patterned articles can be prepared by applying a release polymer to a substrate in a desired pattern, applying a substrate-adherent polymer over the pattern and substrate, and mechanically removing the substrate-adherent polymer from the pattern without requiring solvent. Suitable mechanical removal methods include applying adhesive tape to the substrate-adherent polymer and peeling the tape and substrate-adherent polymer away from the pattern, and abrading the substrate-adherent polymer from the pattern using impact media.

In an optical disk substrate film-formation apparatus which prepared an optical disk by forming a thin film on a substrate, the optical disk substrate is held by a holder section. A contact support surface is provided to the holder section which closely contacts at least a portion of the surface of the optical disk substrate rear to the surface where the think film is formed.
摘要:
A metallo-organic decomposition process for the preparation of intermetallic powders and films. A liquid mixture containing a first metal precursor and a second metal is heated to a temperature in a first temperature range so as to convert the first metal precursor to a first metal followed by heating to a temperature in a second temperature range so as to form an intermetallic compound by a solid state reaction between the first and second metals. The intermetallic compound can be used as a catalyst in cut filler and/or the filter of a cigarette.

In a method for forming one or more features in a thick-film ink deposited on a substrate, a photoimagable material is used to define a negative of the one or more features on the substrate. A thick-film ink is then deposited on at least part of the substrate, abutting at least some of the photoimagable material. The thick-film ink is cured, and the photoimagable material is removed. One embodiment of the method is used to produce a channel plate. Another embodiment of the method is used to produce a switch.
摘要:
A method for manufacturing a fabric coating, which simulates a viscose flocking finish, relative to at least one layer of the fabric coating, and which is particularly relevant to crushed foam coatings, includes the steps of providing fine beads of polymer, which are hollow and partially filled with selected solvents, or solvent blends or other volatile substances, and adding these beads to a coating compound in its wet state. Thereafter, coating the fabric with the resultant compound and oven drying the resulting compound on the fabric, then raising the temperature of the coating to crosslink the polymer and expand the polymer beads within the coating layer. The fabric coating produced by the method, and a fabric coated with the fabric coating made by the method, are also claimed.
摘要:
A device for coating a film with more than two kinds of thickness, including a turntable, a mask and a coating source. The turntable spins regularly. The shape of the mask depends on the thickness of the film and the mask is set close to the substrate. The coating source is set opposite to the turntable, and the mask is set between the coating source and the turntable. The invention also discloses a method for coating a film with more than two kinds of thickness. The method including setting a substrate on a turntable that spins regularly, setting a mask close to the substrate and coating a film on the substrate by a coating source.
摘要:
Process for application of a coating medium on a traveling material web that is one of paper and cardboard, the coating medium including at least one of a pasty medium and a liquid medium, wherein the process includes forming a material web in a wet section of a machine for one of paper and cardboard and guiding the material web which is still wet with a traveling, endless, carrier belt during application of a coating medium. The application of the coating medium includes transferring the coating medium from a roll-coating mechanism to at least one transfer belt onto the still wet material web. The coating medium is transferred from a surface of the at least one transfer belt moving in a direction of travel of the material web. The at least one transfer belt is a traveling, endless, air-permeable transfer belt which is guided by rolls. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
摘要:
Disclosed is a method of surface treatment of a thermoplastic resin film (i) which comprises the steps of subjecting the thermoplastic resin film (i) to surface oxidation, coating the oxidized film with a surface modifier (A) and then stretching the coated film, and which is characterized in that: the surface modifier (A) is an aqueous dispersion prepared by dispersing an olefin copolymer (a) with an unsaturated carboxylic acid or its anhydride bonded thereto in water along with at least one dispersant (b) selected from the group consisting of nonionic surfactants, nonionic water-soluble polymers, cationic surfactants and cationic water-soluble polymers; the ratio by weight of (a)/(b) in terms of the solid content thereof falls between 100/1 and 100/30; and the mean particle size of the resin in the surface modifier (A) is at most 5 nullm. The method can provide a thermoplastic resin film of good melt thermal transfer printability and good offset printability capable of giving prints of good water resistance.
摘要:
A chemical pump includes a pressure chamber, a partition member for dividing the pressure chamber into a cleaning pressure chamber and a discharging pressure chamber, a filter part disposed on the primary side of the discharging pressure chamber, and a single drive mechanism. A pair of openings with respective check valves mounted therein are provided in each of the cleaning and discharging pressure chambers, and are positioned so as to cause a resist solution to flow only in the nullZ direction. The drive mechanism moves the partition member in the nullX direction to cause the resist solution to be sucked into the cleaning pressure chamber and to cause the resist solution to be discharged from the discharging pressure chamber. The drive mechanism moves the partition member in the nullX direction to cause the resist solution to be sucked from the filter part into the discharging pressure chamber and to cause the resist solution to be supplied from the cleaning pressure chamber to the filter part so that the sucked resist solution is equal in amount to the supplied resist solution. This prevents vapor lock and micro-bubble phenomena during the discharge of the resist solution.
