  • Patent number: 7897215
    Abstract: Ion-induced, UV-induced, and electron-induced sequential chemical vapor deposition (CVD) processes are disclosed where an ion flux, a flux of ultra-violet radiation, or an electron flux, respectively, is used to induce the chemical reaction in the process. The process for depositing a thin film on a substrate includes introducing a flow of a first reactant gas in vapor phase into a process chamber where the gas forms an adsorbed saturated layer on the substrate and exposing the substrate to a flux of ions, a flux of ultra-violet radiation, or a flux of electrons for inducing a chemical reaction of the adsorbed layer of the first reactant gas to form the thin film. A second reactant gas can be used to form a compound thin film. The ion-induced, UV-induced, and electron-induced sequential CVD process of the present invention can be repeated to form a thin film of the desired thickness.

  • Patent number: 7361385
    Abstract: The invention relates to a method for manufacturing a hot-dip plated metal strip comprising the steps of: introducing a metal strip into a molten metal bath of plating metal to adhere the molten metal onto the surface of the metal strip; taking out the metal strip, after turning the running direction of the metal strip, from the molten metal bath without applying external force from outside the surface of the metal strip; adjusting the plating weight of the molten metal adhered onto the metal strip; and controlling the shape of the metal strip using magnetic force in non-contact state directly before or after the step of adjusting the coating weight. The invention prevents adhesion of dross to the metal strip without degrading the productivity, and thus manufactures a high quality hot-dip plated metal strip.

  • Patent number: 6197375
    Abstract: Many potential applications of CVD diamond film require the ability to remove a predetermined quantity of material from a surface of the film. We have discovered that such removal is advantageously accomplished by contacting the surface of the polycrystalline diamond film with a metal selected from Fe, Ni, Mn and Ti (preferably Fe and Mn, most preferably Mn), and maintaining the metal-contacted diamond film at a temperature in the range 600-1100° C. (preferably 800-1000° C.) without relative lateral motion between the film and the metal, for an effective time for removal of the quantity of material, exemplarily less than 100 hours. The metal can be in any appropriate form, e.g., a deposited layer, (including a patterned layer), a foil, or powder. We have also discovered that the local thermal conductivity of CVD diamond films typically increases with distance from the lower surface of an as-grown film.

  • Patent number: 5916625
    Abstract: The detrimental effects of fluctuating humidity are neutralized by adjusting the viscosity of a waterborne coating as it is being conducted to the spraying device. A predetermined amount of water or other viscosity modifying additive is mixed continuously with the coating in the coating supply line immediately upstream from the spray device. The amount of water or other additive to be added may be determined by monitoring the humidity in the spray zone. Preferably, an automated feedback control system is employed to adjust the amount of water or other viscosity altering additive being mixed into the coating stream.
