  • Patent number: 9333677
    Abstract: A lubricating system indirectly applies a bladder release agent to a green tire and cures the green tire in a tire curing machine. The system includes a deposition device and a curing bladder. The deposition device directly applies bladder release agent on to a deposition bladder. The deposition bladder is inflated within the green tire in order to deposit the bladder release agent on to an inner surface of the green tire. The curing bladder subsequently receives the green tire with bladder release agent deposited therein and cures the green tire.

  • Patent number: 8252372
    Abstract: A sprayed film forming method and apparatus in which the thickness of the sprayed film in a predetermined region is increased so as to unify the entire thickness. A sprayed film is formed at a cylinder bore inner surface while a spraying gun is moved in an axial direction during rotation inside the bore. Air inside the bore is sucked out to prevent foreign material from being caught in the sprayed film. The flow rate inside the bore tends to become higher at an axial end on a suction side, resulting in a thinned region. The supply speed of a wire serving as a spraying material to the spraying gun or the number of sprays in this region is higher than those at other portions. The thickness at the axial end of the bore is made equal while suppressing an increase in working time and spraying material used.

A nozzle, through which a molten paste of a thermoplastic material kept molten is discharged, is disposed toward an inner peripheral surface of a cylinder. The nozzle is moved along a rotational central line of the cylinder while rotating the cylinder and discharging the molten paste from the nozzle. Centrifugal force acting on the cylinder being rotated leads to spreading of the molten paste applied to the inner peripheral surface of the cylinder. Viscosity of the molten paste, a rotational speed of the cylinder and a speed of movement of the nozzle are set so as to keep the molten paste discharged from the nozzle from being scattered to a region other than the coated region.

  • Patent number: 6565915
    Abstract: In a method for lacquering the inner side of a display screen, a frame is provided to form sealing means for sealing a spacing between a closing means having a passage and closing an inner space of a lacquering head at the top and a display screen covering this passage, in which method an air gap formed between the frame and a peripheral area of a display screen extending substantially parallel to a display screen axis and being bounded by an outer peripheral boundary face constitutes a flow resistance as a result of its dimensions and counteracts the escape of a gaseous medium from the inner space of the lacquering head and through the spacing between a passage boundary face of the passage in the closing means and the outer peripheral boundary face of the peripheral area of a display screen covering the passage in the closing means.

  • Patent number: 6539981
    Abstract: A flow tube has a metal outer tube and is lined with an ETFE fluoropolymer that is resistant to corrosive chemicals and mechanical damage even at high temperatures. The inner surface of the metal tube is coated with a bonding metal that can be securely bonded to the outer metal tube and also forms a strong bond with ETFE fluoropolymer. After the bonding metal has been applied, a layer of a desired thickness of the ETFE fluoropolymer is molded in place to form an inner liner for the flow tube.

  • Publication number: 20020127332
    Abstract: An apparatus for applying powder to at least an interior surface of a hollow object includes a powder discharge device adapted to receive powder and discharge the powder through an outlet. An object holder is configured to hold the object such that the outlet is positioned within the hollow object adjacent the interior surface. A rotating mechanism is configured to engage and rotate the hollow object such that the powder discharged from the outlet coats the interior surface as the interior surface rotates past the outlet. The powder discharge device may be a powder fluidizing bed unit including a chamber with a powder discharge opening in the form of an elongate slot.

  • Patent number: 6423371
    Abstract: A method for forming a bonding on a tapered surface of a wall of a part to substantially eliminate the tapered surface. The method includes positioning the part and a sprayer at a predetermined distance, supplying a bonding material to the sprayer, and applying differing amounts of the bonding material from the sprayer to the tapered surface of the wall of the part to change the tapered surface of the wall of the part to a substantially non-tapered surface.

  • Publication number: 20020076501
    Abstract: A method for preparing a release coating and applying it to crucibles used to contain molten material while it solidifies, such as in the directional solidification of polycrystalline silicon into ingots, by mixing a release coating power with a dry organic binder into a powder and binder dry mixture, mixing a defoamer with a liquid into a liquid and defoamer mixture, mixing the dry mixture with the liquid and defoamer mixture into a wet release coating, sieving to remove lumps and particles, checking the viscosity, wet-spraying onto a crucible at about room temperature, evaporating the liquid from the wet release coating so as to leave a dry release coating on the crucible, and separating the binder from the dry release coating by thermal decomposition.

  • Patent number: 6406742
    Abstract: A coating apparatus for forming a high-resistance film on the inner surface of the neck of the funnel of a cathode ray tube has a nozzle that can be inserted into the neck. The nozzle, which is provided for applying a material liquid to the inner surface of the neck, has a jet hole inclined toward the direction of gravity. The material liquid applied through the jet hole thus inclined scarcely flows upwardly on the inner surface of the neck. The liquid therefore forms a high-resistance film having a uniform thickness on the inner surface of the neck of the funnel. Having a uniform thickness, the high-resistance film inhibits the charge-up of the neck potential, reducing the convergence drift caused by the charge-up of the neck potential.

  • Patent number: 6352745
    Abstract: There are provided methods for making a fragranced glove. The first method comprises the steps of: providing a glove with an inside surface and an outside surface, applying a fragrance to the glove, tumbling the glove to evenly distribute the fragrance, and drying the glove to remove the residual fragrance. The second method comprises the steps of providing a cured glove having an inside surface and an outside surface placed in their proper positions; halogenating the glove; rinsing the halogenated glove in a rinse solution; drying the rinsed glove; and applying a fragrance on the glove. The third method comprises providing a cured glove having an inside surface and an outside surface; halogenating the glove; neutralizing the halogenated glove; rinsing the glove in a rinse solution after neutralizing; drying the rinsed glove; cooling the dried glove; applying a fragrance onto the dried glove; and, tumbling the glove to distribute evenly the fragrance.
