Patent number: 6830323Abstract: A cartridge comprises a pair of housing portions having an opening at a seam formed between the housing portions, a memory chip accessible via the opening to permit electrical contact to be made with the memory chip, and a protuberance projecting from one of the housing portions and welded to the other housing portion within a cavity of the other housing portion. Since a flash which is formed at the weld can spread towards the seam including in the vicinity of the opening, the protuberance and the cavity are mutually dimensioned to restrict the flash substantially to within the cavity. This prevents the flash from spreading into the seam and bulging outward at least in the vicinity of the opening, which could interfere with formation of the seam and making electrical contact with the memory chip.Type: GrantFiled: August 13, 2002Date of Patent: December 14, 2004Assignee: Eastman Kodak CompanyInventors: Mark D. Perkins, Diana C. Petranek

Patent number: 6830324Abstract: In an ink storing container, movable members are properly constructed by molding sheet material into a convex form and are properly welded to a frame. The ink storing container is provided with an air passage section in which an ink meniscus is formed correspondingly to pressure relative to the atmosphere and through which the interior of an ink storing space is in communication with the atmosphere via an air path having a predetermined length. Thus, when negative pressure in the storing space increases, an air is introduced into the space via the air passage section. On the other hand, when the gas in the ink storing section expands to push the ink in the storing space, the ink can be kept in the path. As a result, the interior of the ink storing space is maintained at appropriate negative pressure for ink supply.Type: GrantFiled: December 27, 2002Date of Patent: December 14, 2004Assignee: Canon Kabushiki KaishaInventors: Hideki Ogura, Hiroyuki Ishinaga, Nobuyuki Kuwabara, Tetsuya Ohashi

Patent number: 6830326Abstract: In a four pen ink jet printer comprising cyan, yellow, magenta, and black inks, a clear liquid is applied to printed ink on a print medium via a fifth pen, thereby fixing the colorants, which in turn improves the durability of the printed ink. The clear fixer fluid comprises at least one organic acid and, optionally, a salt of at least one polymeric acid.Type: GrantFiled: October 23, 2002Date of Patent: December 14, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Yi-Hua Tsao, Howard A.

Patent number: 6830327Abstract: The present invention provides ink-jet inks, systems, and methods for marking documents as original. Specifically, an aqueous ink-jet ink can comprise an ink vehicle; and a sufficient amount of particulates having directionally dependent light reflective properties within the ink vehicle such that when the ink-jet ink is substantially dried on a desired substrate, a multi-colored reflected light is emittable in the presence of a light source. Printing documents as original can be carried out for compensation, as a service, or by providing cartridges containing these inks to clients and/or customers.Type: GrantFiled: October 22, 2001Date of Patent: December 14, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventor: Stuart D Asakawa

Patent number: 6830331Abstract: Magnification viewer includes a conventional glasses and a pair of magnifying lens units. The magnifying lens units are fixed to respective eyeglasses of the conventional glasses so that a wearer of the glasses can observe a magnified image of an object through the magnifying lens units. The magnifying lens unit includes an ocular and an objective lens that constitute a Galilean telescope. A prism is disposed between the ocular and the objective lens for deflecting the optical axis of the magnifying lens unit towards an object placed below the head of a wearer.Type: GrantFiled: October 11, 2002Date of Patent: December 14, 2004Assignees: PENTAX CorporationInventors: Masao Jojiki, Phyo Kim

Patent number: 6830332Abstract: According to the invention the ophthalmic lens further comprises a refractive part comprising at least one surface, which is configured to compensate a passing wavefront at least partly for at least one type of monochromatic aberration introduced by at least one of the optical parts of the eye. Said diffractive part is capable of compensating a passing wavefront at least partly for chromatic aberration introduced by at least one of the optical parts of the eye. Furthermore said refractive and diffractive parts together contribute to a required power of the lens.Type: GrantFiled: April 10, 2002Date of Patent: December 14, 2004Assignee: Advanced Medical Optics, Inc.Inventors: Patricia Ann Piers, Hendrik Albert Weeber
