Solvent Vapor Treatment Of Coating Patents (Class 427/335)
  • Patent number: 10485108
    Abstract: A method of, and system for, providing an amorphous fluorinated polymer conformal coating to an RF circuit board is described. A coating solution including the amorphous fluorinated polymer dissolved in a fluorinated solvent is provided. The coating solution is applied to the RF circuit board via a mechanically controlled fluid spray application device to produce a coated board. A predetermined time period is waited for substantial evaporation of the fluorinated solvent from the coated board, thus leaving behind a conformal coating of the amorphous fluorinated polymer on a board surface area.

    Abstract: An inorganic polysilazane resin of the present invention has a Si/N ratio (i.e. a ratio of contained silicon atoms to contained nitrogen atoms) of 1.30 or more. The inorganic polysilazane resin having such a high Si content can be produced by, for example, a method in which an inorganic polysilazane compound containing both Si—NH and Si—Cl is heated to react NH with Cl, a method in which a silazane oligomer (polymer) that leaves no Si—Cl bond is synthesized and a dihalosilane is added to the synthesized silazane oligomer (polymer) to perform a thermal reaction, and the like. A siliceous film can be formed by, for example, applying a coating composition containing the inorganic polysilazane resin onto a base plate and then dried and the dried product is then oxidized by bringing the dried product into contact with water vapor or hydrogen peroxide vapor and water vapor under heated conditions.

Rotation of the substrate is decelerated to a second rotation speed lower than the first rotation speed so that the substrate is rotated at the low speed to smooth the resist solution on the substrate. Rotation of the substrate is then accelerated to a third rotation speed higher than the second rotation speed, and a solvent for the coating solution and/or a dry gas are/is supplied to the resist solution on the substrate. The solvent gas is supplied to a portion of the resist solution on the substrate thicker than a set thickness, and the dry gas is supplied to a portion of the coating solution on the substrate thinner than the set thickness. This thins the thicker portion of the resist solution and thickens the thinner portion to uniform the resist solution.

  • Patent number: 8507047
    Abstract: An approach is described for manufacturing wavelength conversion components for lighting devices which employ in-line process controls to minimize the amount of perceptible variation in the amount of photo-luminescent material that is deposited in the wavelength conversion components. Weight measurements are utilized in the manufacturing process to control and minimize the amount of the variations. In this approach, the weight of the product during manufacturing is used as a surrogate to a measure of the amount of photo-luminescent material in the component, and hence a surrogate for the expected color properties of the manufactured product. By measuring and checking for weight variations for the component, one can quickly determine with reasonable confidence whether there are any variations in the amount of photo-luminescent in the component.

  • Patent number: 7935379
    Abstract: The present invention relates generally to coated medical devices, preferably a stent, that has a drug-eluting surface completely or partially coated with a coating that is imprinted with an impression. In particular, the invention is directed to a coated medical device having a coating that comprises biologically active materials, polymers, or a combination thereof. The coating is imprinted with an impression by printing, molding, lithography, or embossing techniques. Preferably, the patterning imprinted on the coating is capable of releasing biologically active materials in different amounts, at different rates, and/or at different time periods. The invention also relates to methods of making and methods of using the coated medical device.

  • Patent number: 7927650
    Abstract: The beneficial agent is applied into the holes in a medical device in a dry particulate form and is adhered in the hole in a manner that allows release of the drug in a controlled manner. The drug material would be formed into particles and placed in the holes. The solvent would be added to partially liquefy and adhere the drug into the holes. After application of the solvent, the particles are adhered together in a substantially uniform drug containing matrix. The particles may include drug alone or drug in combination with other materials including a matrix.

  • Patent number: 7829143
    Abstract: Organic films can be annealed by exposure to a solvent vapor. The solvent vapor annealing renders the organic film insoluble even in a solvent of a solution from which it was deposited. This enables deposition of two or more organic films in sequence without having one deposition alter an underlying organic film. Devices can be easily fabricated with organic films annealed in this manner when no other solution processing method is possible.
