    Abstract: In a second liquid supply step, a second liquid film and a first liquid film surrounding a side of the second liquid film are formed on an upper surface of a substrate. Then, in a vapor layer formation step, by heating the substrate, a second vapor layer is formed by evaporating the second liquid contacting the upper surface of the substrate, and the second liquid film is held on the second vapor layer. Since the second liquid included in the second liquid film has a high vapor pressure, a height position of a lower surface of the floating second liquid film may be kept high. By blowing a gas to the floating second liquid film, a hole is formed in the second liquid film, and by expanding the hole toward an outer periphery of the substrate, the first liquid and the second liquid are removed outside the substrate.

    Abstract: A conductive coating may be adhered to a structure comprising a hydrophobic and/or adhesion-resistant surface. The conductive coating may have a polymer backbone with conductive particles suspended in the backbone. In some embodiments, the conductive coating may be applied directly to the surface. In other embodiments, the conductive coating may be indirectly applied by first applying a primer adhesive to the outer surface, and then applying the conductive coating over the primer adhesive. An example structure may be a catheter of an endoscopic medical device, such as a bipolar sphincterotome, where the conductive coating functions as a return electrode.

    Abstract: The present invention provides a coating method including: a step of supplying a coating agent to a surface of a lens base material; a spreading step of spreading the coating agent supplied to the surface by rotation of the lens base material; a first removal step of removing at least a part of a liquid pool of the coating agent generated on a peripheral edge portion and/or a side surface portion of the lens base material by rotation of the lens base material after the spreading step; and a second removal step of removing the liquid pool remaining on the peripheral edge portion and/or the side surface portion of the lens base material by bringing an adsorption member into contact with at least the side surface of the lens base material after the first removal step. According to the present invention, it is possible to provide a coating method capable of obtaining a base material having a coating layer excellent in uniformity of film thickness by reducing the liquid pool of the coating agent generated on the peripheral edge portion and/or the side surface portion of the lens base material when the coating layer is formed on the surface of the base material by spin coating the coating agent.
