  • Publication number: 20150360455
    Abstract: The present invention provides a method of applying a photocurable resin on a surface of a panel. A difference in a surface level is formed on a peripheral portion on the surface of the panel. The method includes a step of moving either one of an application head and the panel so that the application head provided with a slit-type nozzle which discharges a photocurable resin relatively moves on the surface of the panel, and an application step of discharging the resin from the nozzle onto the surface of the panel during the moving step. In the application process, a film thickness of the resin is controlled so that a difference in a surface level is not generated on a liquid film surface of the resin on the difference in a surface level on the panel.

  • Patent number: 9162246
    Abstract: A filling method exhausts gas from inside a slit nozzle that applies coating liquid onto a substrate surface while filling the slit nozzle with the coating liquid. The slit nozzle includes a coating liquid supply opening, a coating liquid discharge outlet, a manifold that is connected to the supply opening and holds the coating liquid inside the slit nozzle, a liquid channel that is connected to the manifold and supplies the coating liquid to the discharge outlet of the slit nozzle, and a ventilation hole for exhausting gas from inside the manifold. The filling method includes: a discharge outlet closing process that closes the discharge outlet while the coating liquid is being fed from the supply opening into the slit nozzle; and a ventilation hole opening process that opens the ventilation hole.

  • Patent number: 4810387
    Abstract: A method for extracting and removing water-soluble substances from a non-water-soluble fluid containing water-soluble substances by using water or an aqueous solution as the extractant and bringing the non-water-soluble fluid and the water or aqueous solution into contact with each other by means of filters.
