Other embodiments of the invention will also have a first dispenser for particles disposed above the disc. Also conveniently, the coater will also have a second dispenser for particles disposed above the disc. In one application for which the coater can be employed, the first dispenser will be adapted to dispense a mixture of sand particles and polymeric resin, and the second dispenser will be adapted to dispense retroreflective glass beads.Type: GrantFiled: January 21, 2004Date of Patent: May 29, 2007Assignee: 3M Innovative Properties CompanyInventor: Steven J.

Coating liquid application apparatus, image printing apparatus and coating liquid application method
Patent number: 7211151Abstract: A coating liquid application apparatus is provided which can apply a coating liquid, such as a coating agent for improving a weatherability of a printed surface, to the printed surface of a print medium automatically and at high speed. For this purpose, this invention uses application mechanisms to apply the coating liquid to the print medium that was ink-printed with an image. Each application mechanism has a pair of rollers supplied with the coating liquid. Multiple stages of such application mechanisms are provided. The print medium is passed between the paired rollers successively from one application mechanism to another to apply the coating liquid to the print medium in a plurality of stages.Type: GrantFiled: May 13, 2005Date of Patent: May 1, 2007Assignee: Canon Kabushiki KaishaInventors: Nobuhiko Takekoshi, Tetsuo Kikuchi -
Patent number: 7144442Abstract: A degassing device capable of regulating an amount of air dissolved in a liquid. A device for measuring amounts of dissolved oxygen measures the amount of oxygen dissolved in one of a coating liquid which has yet to be degassed, and is to be fed to a film degassing device, and a coating liquid which has been degassed and discharged from the film degassing device. Based on measured results, a control unit regulates the degree of opening of a vacuum valve so as to change the degree of degassing performed by the film degassing device, thereby suppressing fluctuations in an amount of oxygen dissolved in the coating liquid. A load never constantly acts on the film all the time, the film life can accordingly be extended, thus resulting in reductions in running costs.Type: GrantFiled: February 13, 2004Date of Patent: December 5, 2006Assignee: Fuji Photo Film Co., Ltd.Inventor: Kenji Hayashi

Patent number: 7138014Abstract: An apparatus and a method of depositing a catalytic layer comprising at least one metal selected from the group consisting of noble metals, semi-noble metals, alloys thereof, and combinations thereof in sub-micron features formed on a substrate. Examples of noble metals include palladium and platinum. Examples of semi-noble metals include cobalt, nickel, and tungsten. The catalytic layer may be deposited by electroless deposition, electroplating, or chemical vapor deposition. In one embodiment, the catalytic layer may be deposited in the feature to act as a barrier layer to a subsequently deposited conductive material. In another embodiment, the catalytic layer may be deposited over a barrier layer. In yet another embodiment, the catalytic layer may be deposited over a seed layer deposited over the barrier layer to act as a “patch” of any discontinuities in the seed layer. Once the catalytic layer has been deposited, a conductive material, such as copper, may be deposited over the catalytic layer.Type: GrantFiled: January 28, 2002Date of Patent: November 21, 2006Assignee: Applied Materials, Inc.Inventors: Joseph J. Stevens, Dmitry Lubomirsky, Ian Pancham, Donald J. K. Olgado, Howard E. Grunes, Yeuk-Fai Edwin Mok

Patent number: 6932868Abstract: A substrate is horizontally held by a substrate holding portion freely movable in the Y-direction, and a nozzle portion is provided above and opposing the substrate, and movable in X-direction corresponding to the coating liquid feeding region of the substrate. A discharge opening is formed at a lower end of the nozzle portion, and a channel connecting the discharge opening with a coating liquid feed tube coupled to an upper end of the nozzle portion is formed within the discharge opening. At the mid-stream of the channel, a liquid pool portion larger in diameter than the discharge opening is formed, the inside of which is provided with a filtering member formed by porous bodies blocking the channel. The filtering member forms a pressure loss portion, which absorbs pulsation occurring at the coating liquid feed tube before it reaches the discharge opening.Type: GrantFiled: September 28, 2004Date of Patent: August 23, 2005Assignee: Tokyo Electron LimitedInventors: Takahiro Kitano, Norihisa Koga, Toshichika Takei, Yoshiyuki Kawafuchi

Patent number: 6923865Abstract: Techniques for precisely controlling the size of particles in a coating solution delivered to a coating apparatus involve continuous classification of coating particle size using a tangential flow filter assembly. The techniques may be particularly useful in the preparation of coating dispersions for manufacture of magnetic recording media. A classification technique makes use of a tangential flow filter assembly that permits delivery of coating particles below a maximum size threshold to a coating path. The filter assembly may be disposed in a circulation path that includes one or more processing devices to reduce the size of coating particles carried by a coating solution. The filter assembly enables coating particles above the maximum size threshold to be recirculated through the circulation path and subjected to repeated processing to reduce particle size to a desired size range.Type: GrantFiled: March 29, 2002Date of Patent: August 2, 2005Assignee: Imation Corp.Inventors: Mark Serafin, Stanley R. Ellis, Leroy C. Erickson, Scott A. Walker, Daniel W. Brandt

Patent number: 6884281Abstract: First, the overall quantity of bubbles in a coating liquid is reduced in advance by vacuum deaeration performed in conjunction with preparation of the coating liquid in a stirring tank in a first step, then bubbles of relatively large sizes, of bubbles that have not been removed in the first step are removed by a tank type deaeration device with ultrasonic waves in a floatation tank in a second step, and finally bubbles of very small to small sizes that are difficult to remove in the first and second steps are dissolved in the liquid under pressure with ultrasonic waves and thereby removed in a pipeline in a third step. According to this, bubbles in the coating liquid can reliably be removed irrespective of the nature of the coating liquid, a large amount of coating liquid can be treated, and the possibility that the quality of the deaerated coating liquid is adversely affected is eliminated.Type: GrantFiled: March 5, 2003Date of Patent: April 26, 2005Assignee: Fuji Photo Film Co., Ltd.Inventor: Yasuo Takahashi
