Patent number: 7459176Abstract: A functional film fabrication method for fabricating a functional film on a base having a flat surface includes an installation step and an application step. In the installation step, a base is installed so that the flat surface is on top, and a droplet discharge head with a plurality of nozzles aligned in a first direction is arranged above the flat surface. In the application step, a functional film is fabricated on the flat surface by repeating a discharge step and a nozzle movement step. In the discharge step, droplets of a functional liquid are discharged from the nozzles onto the base. In the nozzle movement step, the nozzles are moved relative to the base in a second direction perpendicular to the first direction over a distance shorter than the distance between the nozzles in the first direction.Type: GrantFiled: March 10, 2004Date of Patent: December 2, 2008Assignee: Seiko Epson CorporationInventor: Kazuaki Sakurada

Publication number: 20080292787Abstract: The present invention relates to a process of edging a lens comprising forming a lens-protective transparent coating layer on the surface of the lens. When the lens coated with a transparent coating layer comprising a fluorine-containing elastomer and optionally a fluorine-containing organosilane compound and having a surface energy of less than 15 mJ/m2 is edged, the scratch of lens during handling, the damage of lens caused by chemical contaminants, and lens off-centring phenomena can be prevented. Further, such an edging process requires no adhesive tape, making the process simple, and prevents the contamination of the lens surface. Further, the inventive transparent coating layer makes it possible to measure the diopter of lens exactly owing to its transparency and it is manually removable without a chemical.Type: ApplicationFiled: March 27, 2007Publication date: November 27, 2008Applicant: Essilor International (Compagnie Generale d'OptiqueInventors: Hun Rae Kim, Jeong Ki Kang, Ja Heung Koo, Sun Do Lee

Patent number: 7455889Abstract: Holographic data storage media having a sandwiched construction are described in which a holographic recording material is sandwiched between two substrates. The holographic media formulation is often formed of two or more components mixed to obtain a homogeneous formulation. The holographic media formulation may include two or more components which are mixed together prior to injection between the substrates. Curing of the holographic media formulation is substantially avoided during mixing, yet accelerated after the formulation is injected between the substrates. Accordingly, the system and techniques can be used to improve the large scale manufacturability of such media by allowing for fabrication of such media within reasonable cycle times, such as less than one minute, while adhering to stringent requirements for optical clarity and parallelism.Type: GrantFiled: March 24, 2004Date of Patent: November 25, 2008Assignee: Imation Corp.Inventors: Jathan D.
