Publication number: 20140226199Abstract: As a protective insulating layer coating the outer surface of a electrochromic device of an electrochromic mirror, a coating film of synthetic resin material is used instead of a conventional glass substrate. Further, sufficient durability is ensured against usage environment. As the synthetic resin material a solvent-soluble fluorine copolymer resin including a copolymer of a fluoroolefin monomer and an acrylate monomer is used. The resin is dissolved in a solvent to provide a coating fluid. The coating fluid is formed as the protective insulating layer covering the outer surface of the electrochromic device and the laminated end faces of the respective films.Type: ApplicationFiled: October 11, 2012Publication date: August 14, 2014Inventor: Tomoyuki Kukita

Patent number: 7423521Abstract: In a vehicular visual assistance system, an image picked up by an image pickup device is processed by an image processing device, and displayed on a display monitor. The image pickup device is mounted on a lower part of a door mirror housing, and is capable of picking up an image of a region that is continuous in the fore-and-aft direction. The imaged region includes part of a front region directly viewed by a vehicle driver, and part of a rear region indirectly viewed by the vehicle driver via a door mirror. The image processing device displays, on the display monitor, an imaged region for which at least front and rear boundaries thereof of the viewed regions overlap. Thus, it is possible to avoid a blind spot from occurring between the direct and indirect views and the image based on the picked up image, thereby improving visibility.Type: GrantFiled: November 3, 2005Date of Patent: September 9, 2008Assignee: Kabushiki Kaisha Honda LockInventors: Tomoyuki Kukita, Hiroshi Sakamoto
