Reverse roll coating may be used to coat the two surfaces of the sheet of laminate material. The method described is particularly suited for applying a substance providing balancing characteristics desirable in the end product to one side of the laminate material and applying a substance providing other characteristics desirable in the end product to the other side of the laminate material. For example, a balancing substance may be applied on one side of a kraft paper sheet and a substance providing structural bonding applied to the other side, thereby eliminating the need to use a discrete balancing sheet in a laminate.Type: GrantFiled: March 12, 1999Date of Patent: August 26, 2003Assignee: Premark RWP Holdings, Inc.Inventors: Joel Lane Williams, Earl Soudelier, Donald M.

Patent number: 6592931Abstract: In a coating method, a precoating layer is applied to one surface of a web W laid between a plurality of web guide rollers GR while a leading end surface of an extrusion-type head portion EX is pressed against the one surface of the web. Accordingly, entrained air increasing as the transferring speed of the web becomes higher could be prevented from entering a coating point on a doctor edge surface near an outlet of a slot by the meniscus of coating liquid formed in a slight gap between the front edge surface of the extrusion-type head portion and the one surface of the web approaching there. As a result, the precoating layer having an excessive amount can be applied stably without turbulence at the coating point caused by the entrained air. Further, coating can be done stably in the rod portion by setting the thickness of the precoating layer for a final coating layer and a virtual coating layer.Type: GrantFiled: October 26, 1999Date of Patent: July 15, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Hideaki Takekuma, Mikio Tomaru

Patent number: 6589598Abstract: The present invention provides a method for coating a plate with a coating solution comprising the steps of: holding the plate in such a manner that surfaces of the plate to be coated are aligned substantially parallel to a gravity direction; moving the plate in a direction parallel to the surfaces of the plate and at a right angle to the gravity direction; passing the plate between two coating rolls to which the coating solution is applied, which rolls rotate in the same direction as that of the plate while being in contact with the surfaces of the plate, and which rotation axes are substantially perpendicular to a moving direction of the plate and to normal direction of the surfaces of the plate; and forming a film of the coating solution on at least one surface of the plate.Type: GrantFiled: November 7, 2001Date of Patent: July 8, 2003Assignees: Sumitomo Chemical Company, Limited, Meihan Shinku Kogyo Company LimitedInventors: Shinsuke Ochiai, Nissho Iwamoto

Patent number: 6565925Abstract: A method for producing coated strands of metal includes guiding a metal strand through the bottom of a vessel filled with a molten mass of the same or different composition as the metal strip, wherein the residence time of the metal strand is selected as a function of at least one of the molten bath level, the casting speed, the metal strand thickness, and the preheating temperature of the metal strand such that the deposited molten mass on the metal strand has a desired thickness of several times the initial thickness of the metal strand. After exiting from the molten bath, the metal strand with a layer crystallized thereon is subjected to a smoothing path carried out when the surface temperature of the strand crystallized thereon is smaller than the solidus temperature of the molten bath, so that at least the surface of the layer crystallized thereon is solidified. The crystallized layer is applied with a thickness which exceeds the desired final thickness of the coated strand.Type: GrantFiled: July 18, 2001Date of Patent: May 20, 2003Assignee: SMS Schloemann-Siemag AktiengesellschaftInventor: Fritz-Peter Pleschiutschnigg

Patent number: 6565916Abstract: A method for producing an oxide cathode including a sleeve containing a heater coil, a cathode substrate provided on one end of the sleeve, and an emissive material layer formed by thermally decomposing an alkaline earth metal carbonate layer adhered onto the cathode substrate, which method includes adhering the alkaline earth metal carbonate onto the cathode substrate so that it has a bulk density of 0.5 to 0.8 g/cm3, then pressing it so that the bulk density becomes not more than 0.9 g/cm3, and then thermally decomposing it in vacuum. Accordingly, an oxide cathode in which the current density distribution of emission electrons is smooth and an electron emission characteristic is not deteriorated when operated for a long time is realized, and a method for producing a cathode-ray tube with high resolution in which moire is invisible is provided.Type: GrantFiled: February 20, 2001Date of Patent: May 20, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshiki Hayashida, Yoshikazu Iwai, Shinji Sasaki

Publication number: 20030068523Abstract: A highly corrosion-resistant material and a corrosion-resistant member which are improved in corrosion resistance, adhesion, contact electrical resistance, electrical conductivity, airtightness, etc. and are suitable for use as, e.g., a metallic separator for polymer electrolyte fuel cells (PEFC); and a process for producing them. A thin noble-metal layer is formed on the desired part of the surface of a metallic base and then subjected to compression working. The coated base may further be subjected to anticorrosive treatment with a liquid phase containing a peroxide or ozone or with an active gas atmosphere.Type: ApplicationFiled: February 28, 2002Publication date: April 10, 2003Inventors: Yasushi Kaneta, Shinobu Takagi, Hiroaki Yoshida, Yoshihisa Suzuki, Masaki Shinkawa

Patent number: 6544590Abstract: In a coating method for forming a film of a coating material on a substrate by supplying the coating material from a coating unit to the substrate held by a stage while the coating unit is moved relative to the stage, the stage includes a substrate-holding section and a peripheral section which has a surface higher than that of the substrate-holding section. The coating method includes the steps of mounting the substrate on the substrate-holding section of the stage; forming the film of the coating material so that the coating covers the substrate and extends to the peripheral section; and removing the coating material remaining in the peripheral section by a coating material removing unit after the substrate provided with the film is dismounted from the stage.Type: GrantFiled: October 25, 2000Date of Patent: April 8, 2003Assignee: Canon Kabushiki KaishaInventors: Yasuto Kodera, Fumikazu Kobayashi, Toshinori Furusawa
