  • Patent number: 10186661
    Abstract: A method for enhancing charge carrier mobility of a field-effect transistor device. The method comprises generating uniaxial nanogrooves on a substrate and blade coating a solution comprising a semiconducting polymer onto the substrate. The polymer solution is spread onto the substrate in a direction parallel to the nanogrooves and a main-chain axis of the polymer is parallel to the nanogrooves. The semiconducting polymer can be then annealed, so that a polymer film is formed which is layered on top of the substrate, with polymer chains aligned parallel to a direction of charge carrier movement.

The periphery has a first slot and a substantially opposing second slot. Each of the first and second slots is sized to permit a first end of a tape located on a roll to be slid through it. A tape holder may be connected to the container so that the tape holder lies outside of the cavity of the container. The roll of tape can be placed on the tape holder so when the tape is pulled through the “mud box”, the tape is thereby unwound. As the tape is manually pulled through the “mud box”, joint compound is thinly applied to one side of the tape. As this is done, the joint compound begins to “adhere” to the tape, conditioning the tape for excellent wall adhesion.

  • Patent number: 7022380
    Abstract: Method and apparatus for coating a traveling paper web includes a coater head. The coater head includes an inlet for receiving fresh coating material which is introduced into a mixing chamber. A looped flow path is established within the coater head which includes a feed channel extending from the mixing chamber and leading into a coating chamber where one portion of the coating material proceeds in the direction of the rotating backing roll. The aqueous slurry of coating material near the downstream end of the coating chamber enters a recirculation channel from which it is directed through a plurality of flow metering orifices back into the mixing chamber.

  • Patent number: 6926772
    Abstract: Continuous void-free uniform coatings are formed on filamentous articles by applying a voided or otherwise substantially uneven coating to at least some of the exposed portion of a filamentous article or to a rotating substrate. The filamentous article or substrate is passed through an improvement station containing a plurality of coating-wetted rolls that contact and re-contact the wet coating at different positions along the length of the filamentous article or rotating substrate, wherein the periods of the rolls improve the uniformity of the coating. For coatings applied to a rotating substrate, the uniform wet coating is transferred to the filamentous article. The final coating can be very thin, very uniform and completely or substantially void-free. The coating improvement can be quickly and easily obtained using low cost equipment.

  • Patent number: 6869639
    Abstract: An improved film coater which utilizes one or more coater or applicators to transfer coating to the outer surfaces of at least one more rolls, which in turn transfers the coating from the roll surface to one or more sides of the web for coating paper is disclosed. The coater or applicator includes a smoothing doctor on the web and downstream of the one or more rolls, and may also utilize humidity from one of steam showers or a humidity enclosure to assist smoothing. The web may run in any direction, but preferably runs upwardly from the roll toward the doctor to reduce “film split” droplets effect. The present invention also reduces the fiber rise and arrange peel pattern on the coated web, resulting in a smooth uniform coated paper.

    Abstract: A coater to coat web includes an extrusion die, which has a die slot, for ejecting coating solution. A valve is disposed downstream from first and second conduits, for selectively feeding coating solution and bubble removing liquid to the extrusion die. A shifting mechanism moves the extrusion die between an offset position and a coating position. A controller causes the shifting mechanism to set the extrusion die in the offset position, feeds the bubble removing liquid to the extrusion die by setting the valve at the first conduit, feeds the coating solution by setting the valve at the second conduit, and causes the shifting mechanism to move the extrusion die to the coating position, to eject the coating solution from the extrusion die in the coating position. A bead of the coating solution is formed, for applying the coated layer to the web.

  • Patent number: RE40857
    Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes. The base sheet of the coated paper is preferably formed square on a paper machine wet end and has on the order of 40-50% less filler than conventional sheet paper made for electrophotographic processes. After being formed and dried, the base sheet is provided with a top coat weight that is approximately 60% less than the typical coat weight used for conventional paper. The coating is formulated to have sufficient viscosity to stay more on the surface of the base sheet. The coated sheet is calendered to a medium gloss on the order of a 75° TAPPI gloss of about 45, both to preserve a degree of surface roughness to enhance runnability of the paper through an electrophotographic copier and to provide a pleasant and easily readable surface.
