  • Patent number: 6287636
    Abstract: A coating apparatus comprising a plurality of paint supply devices, a mouthpiece for dispensing a paint supplied from the paint supply devices, and a stage for holding a coated object. The mouthpiece comprises a plurality of outlet ports. Also, a coating method comprising relatively moving a mouthpiece and a coated object to coat the coated object with paint in which a diluent is added to the paint to form a paint/diluent mixture upon the start of the coating process. This paint/diluent mixture is used to coat the coated object upon the start of the coating process and until the process reaches a steady state. The flow of diluent is then stopped and the coating process is continued using only the paint in a steady state coating process. The flow of diluent is then started again to form a paint/diluent mixture as the coating process ends. A coating with a highly uniform thickness along the entire length of the coated object is produced by this method.

  • Patent number: 6277443
    Abstract: A batch process for making galvanized steel products with a low lead or no lead zinc coating is described. Metal parts are cleaned, rinsed, pickled and rinsed and are immersed in a hot, pre-flux solution and thoroughly dried before they are immersed in a molten zinc bath. The dryer system includes a mechanism for rotating the batch of parts as they are dried. In one embodiment of the invention, a batch of steel pipe is dried by hot air having a maximum temperature of 125° C. The descrambler system rotates the pipe and moves the pipe in contact with the divider apparatus to separate the pipe in the dryer. The pipe, thoroughly dried, is immersed into a molten zinc bath having less than 0.05% by weight lead, and the use of a top-flux on the molten zinc bath is optional.

  • Patent number: 6277441
    Abstract: According to the invention disclosed, application liquid such as spin-on-glass (SOG) is dropped on the surface of a substrate such as a semiconductor wafer having irregularities thereon and is dispersed on the substrate surface using a centrifugal force generated by rotating the substrate. The rotation of the substrate is performed in a first rotational action at a low speed and a second rotational action at a high speed, the first and second rotational actions being separated by a time interval. The second rotation may be at a constant speed. Alternatively, the rotational speed of the second rotational action may comprise rotation at an intermediate speed continuously followed by rotation at a higher speed. The time interval between the first and second rotational actions is ten times the duration of the first rotational action or longer. The duration of the second rotational action is three times that of the first rotational action or longer.

  • Patent number: 6270572
    Abstract: A thin film manufacturing method is provided. The method includes the step of chemically adsorbing a first reactant on a substrate by injecting the first reactant into a chamber in which the substrate is loaded. Physisorbed first reactant on the chemically adsorbed first reactant is removed by purging or pumping the chamber. After the first reactant is densely chemically adsorbed on the substrate by re-injecting the first reactant into the chamber, the physisorbed first reactant on the dense chemisorbed first reactant is removed by purging or pumping the chamber. A second reactant is chemically adsorbed onto the surface of the substrate by injecting the second reactant into the chamber. Physisorbed second reactant on the chemisorbed first reactant and the second reactant is removed by purging or pumping the chamber. A solid thin film is formed by chemical exchange through densely adsorbing the second reactant onto the substrate by re-injecting the second reactant into the chamber.

  • Patent number: 6270842
    Abstract: A steel material subjected to preliminary treatments to remove an oxide film on the surface is immersed in a molten flux bath in an independent vessel and thereafter immersed in a molten zinc-aluminum alloy bath in a separate vessel to be galvanized with a coating of the alloy. The molten flux bath consists essentially of 5-25 wt % of an alkali metal chloride, typified by sodium chloride, or an alkaline earth metal, and the balance being zinc chloride. The flux bath may additionally contain 1-5 wt % of an alkali metal fluoride typified by sodium fluoride. The method allows for inexpensive, efficient and one-stage galvanizing with a corrosion-resistant molten zinc alloy of a high aluminum content to produce a smooth, uniform and beautiful galvanized layer on the surfaces of various steel materials.
