Patent number: 8693092Abstract: A focusing module for long focal length telescope which includes a sliding plate, a fixing sleeve, and a fixing bolt is disclosed. The drawtube is disposed on the sliding plate for sliding forward or backward to focus. The fixing sleeve and the fixing bolt form a connecting mechanism. When screwing the fixing sleeve to clamp the sliding plate from the bottom, the fixing bolt will be driven to clamp the sliding plate from the top simultaneously. This prevents the main tube and the drawtube from being displaced, and the target can be kept in the field of view of the telescope.Type: GrantFiled: December 30, 2010Date of Patent: April 8, 2014Inventor: Ching-Hsi Chiang

Patent number: 8693094Abstract: A method for manufacturing a polarizer utilizes a support, which is coated with a photoresist. A carbon nanotube film is located over the photoresist, and one portion of the carbon nanotube film is submerged in the photoresist. Metal or semi-metallic particles are deposited over the carbon nanotube film and the photoresist, which is removed. The carbon nanotube film with the metal particles or semi-metallic particles is adhered to a substrate to obtain the polarizer.Type: GrantFiled: May 16, 2010Date of Patent: April 8, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Sei-Ping Louh

Patent number: 8693097Abstract: A coated article includes a temperable antireflection (AR) coating that utilizes medium and low index (index of refraction “n”) layers having compressive residual stress in the AR coating. In certain example embodiments, the coating may include the following layers from the glass substrate outwardly: silicon oxynitride (SiOxNy) medium index layer/high index layer/low index layer. In certain example embodiments, depending on the chemical and optical properties of the high index layer and the substrate, the medium and low index layers of the AR coating are selected to cause a net compressive residual stress and thus optimize the overall performance of the antireflection coating when the coated article is tempered and/or heat-treated.Type: GrantFiled: September 3, 2010Date of Patent: April 8, 2014Assignee: Guardian Industries Corp.Inventors: David M. Broadway, Yiwei Lu, Willem den Boer, Darrell Golden, Paul Patriacca, Gregory Scott

Patent number: 8693098Abstract: A projection objective for a microlithographic EUV projection exposure apparatus includes a first mirror and a second mirror. The first mirror includes a mirror substrate and a reflective coating carried by the mirror substrate. The second mirror includes a mirror substrate and a reflective coating carried by the mirror substrate. The first and second mirrors are configured so that, with otherwise equal irradiation by EUV light, the mirror substrate of the first mirror compacts less than the mirror substrate of the second mirror under the effect of the EUV light.Type: GrantFiled: October 14, 2010Date of Patent: April 8, 2014Assignee: Carl Zeiss SMT GmbHInventors: Siegfried Rennon, Hans-Juergen Mann, Thomas Schicketanz

Patent number: 8693099Abstract: An antireflection film capable of reliably preventing light (or laser light), which is incident on a glass substrate and which reaches a metal film, from being reflected by the metal film. The antireflection film provided between a metal film having a complex refractive index represented by NM=nM?i·km and a glass substrate having a refractive index NG includes, from the metal film side: (A) a first dielectric layer having a refractive index N1; (B) a second dielectric layer provided on the first dielectric layer and having a refractive index N2; and (C) a third dielectric layer provided on the second dielectric layer and having a refractive index N3, in which N1<nM, N1>NG, N2<NG, and N3>NG hold. Accordingly, light which is incident on the glass substrate and which reaches the metal film is prevented from being reflected by the metal film.Type: GrantFiled: July 24, 2007Date of Patent: April 8, 2014Assignee: Japan Display West Inc.Inventors: Toshitaka Kawashima, Shigeo Kubota, Naoya Eguchi, Koichi Tatsuki, Junichi Ohsako

Patent number: 8693100Abstract: A method of easily manufacturing a light diffusion film by a continuous process, which achieves both good display properties and an increase in viewing angle when used in a liquid crystal display. A method of manufacturing a light diffusion film includes forming a laminate of an original light diffusion film and a photosensitive resin, wherein the photosensitive resin includes at least two types of materials that are different in refractive index from each other; and irradiating the laminate with a collimated laser beam from a side of the original light diffusion film, wherein a reflection hologram formation-preventing layer is located on a side of the laminate opposite from the side of irradiation of the laminate with a collimated laser beam. In the process of irradiating the laminate, the reflection hologram formation-preventing layer prevents formation of a reflection hologram on the photosensitive resin due to a reflected light from the irradiation.Type: GrantFiled: September 8, 2009Date of Patent: April 8, 2014Assignee: Nitto Denko CorporationInventors: Taku Yamada, Hin Hou, Kentarou Takeda
