20090230573 | Gas Dissolving Apparatus - A dissolving apparatus has a cylindrical tubular container closed at both ends with its center axis being inclined to the horizon. A center of an interface between a gas and a liquid in the container is positioned at a center in a lengthwise direction of a side wall of the container. Two inner spaces of the container above and below the interface are referred to as a gas section and a liquid section. An injection inlet for injecting a gas-liquid mixed fluid into the container is provided at a level corresponding to, or lower than, the interface. A liquid outlet for discharging the liquid is provided near a bottom of the liquid section of the container. Since the container is inclined, the interface can have an area large enough to promote dissolution of the gas into the liquid. Since the depth of the liquid in the liquid section is sufficiently deep, the liquid can be prevented from being discharged through the liquid outlet with large gas bubbles being present therein. | 09-17-2009 |

20120045170 | OPTICAL WAVEGUIDE FOR TOUCH PANEL - An optical waveguide for a touch panel is capable of causing light beams emitted from a light-emitting optical waveguide section to enter a light-receiving optical waveguide section even when warpage or distortion occurs. Edges of an over cladding layer covering an end surface of a core for emitting a light beams and an end surface of a core for receiving the light beams respectively are configured in the form of light-emitting and light-receiving lens portions each having an outwardly-bulging arcuately curved surface as seen in vertical sectional view. The light-emitting lens portion has one of the following configurations: a configuration in which a light beam emitted from the light-emitting lens portion is adapted to diffuse in the direction of the height of the light-emitting lens portion; and a configuration in which the height of the light-emitting lens portion is less than that of the light-receiving lens portion. | 02-23-2012 |
20120099818 | OPTICAL WAVEGUIDE FOR TOUCH PANEL - The optical waveguide is disposed along the periphery of a display screen of a display of a touch panel. A light-emitting optical waveguide section and a light-receiving optical waveguide section are disposed in an alternating pattern along each edge of the display screen. Both of the light-emitting optical waveguide section and the light-receiving optical waveguide section are coupled together by placing end surfaces of end portions of the light-emitting optical waveguide section and the light-receiving optical waveguide section in abutment with each other. The light-emitting optical waveguide section includes cores each having an end portion provided in the form of a light-emitting lens portion. The light-emitting lens portion has an end surface provided in the form of a light-emitting lens surface. The light-receiving optical waveguide section includes cores each having an end portion provided in the form of a light-receiving lens portion corresponding to the light-emitting lens portion. | 04-26-2012 |
20120107517 | METHOD OF MANUFACTURING OPTICAL WAVEGUIDE FOR TOUCH PANEL - A method of manufacturing an optical waveguide for a touch panel is provided which achieves a small dimensional change due to heat to provide precise formation positions of a cladding layer and cores on a substrate. The method includes: selecting an elongated substrate made of stainless steel to continuously apply a first photosensitive resin composition; heating the first photosensitive resin composition to volatilize a solvent therein; irradiating the first photosensitive resin composition to form the cladding layer; continuously applying a second photosensitive resin composition; heating the second photosensitive resin composition to volatilize a solvent therein; and irradiating the second photosensitive resin composition with irradiation light through a photomask to expose the second photosensitive resin composition to the irradiation light, and thereafter dissolving away unexposed portions of the second photosensitive resin composition by using a developing solution. | 05-03-2012 |
20120164313 | METHOD OF MANUFACTURING OPTICAL WAVEGUIDE - A method of manufacturing an optical waveguide is provided which enables a recognition device such as a CCD camera to easily recognize an alignment mark for positioning a mold for over cladding layer formation. The method includes the steps of: forming protruding cores and a protruding alignment mark on an upper surface of an under cladding layer on a substrate by a photolithographic method; and forming the over cladding layer by use of the mold positioned using the alignment mark as a guide. For the formation of the alignment mark, a photomask is used which has an opening pattern for alignment mark formation including an opening, and a light transmission amount reduction region provided around the opening and having an aperture ratio within a range greater than 10% and less than 80%. The alignment mark is formed to have a peripheral side surface in the form of an inclined surface. | 06-28-2012 |
20130009911 | UNDERLAY-BOARD-EQUIPPED INPUT DEVICE - An underlay-board-equipped input device is provided which is capable of preventing positional displacement of a writing paper sheet when a user is writing on the set writing paper sheet and when the writing paper sheet is set again. An underlay board is mounted to the back surface of a rectangular frame-shaped input device having a rectangular hollow input-use interior pivotably about one end edge of the input device. The input device includes a rectangular frame-shaped optical waveguide having the hollow input-use interior. A means for positioning a writing paper sheet (such as protrusions) is provided on the front surface of the underlay board. The front surface of the underlay board and the back surface of the input device are configured to form a holding part for holding the writing paper sheet therebetween. | 01-10-2013 |
20140198357 | IMAGE READING DEVICE AND IMAGE FORMING APPARATUS THEREWITH - An image reading device has an optical unit, a pair of rail portions, and a driving device. The optical unit reads an image on the document. The pair of rail portions support the optical unit such that this is slidable in the sub scanning direction. The driving device enables the optical unit to move in the sub scanning direction. The driving device engages with the optical unit substantially at the position of its center of gravity in the main scanning direction, and the pair of rail portions are arranged one on each of one and the other sides in the main scanning direction so as to be equidistant from the position of the center of gravity. | 07-17-2014 |
20140293584 | DISPLAY DEVICE AND IMAGE FORMING APPARATUS - A display device includes a light source and a light-transmissive display plate. The display plate is disposed at the light-emitting side of the light source. The display plate has an inner surface facing toward the light source and an outer surface facing away from the inner surface. The inner surface and the outer surface of the display plate each have a grain finish. The grain finish on the outer surface is finer in grain roughness than the grain finish on the inner surface. | 10-02-2014 |
