20130342598 | INKJET PRINTER - In an inkjet head, at least one of a plurality of nozzle arrays to eject ink of different colors from one another is arranged with nozzles displaced in position from nozzles of the other nozzle arrays in an arrangement direction of the nozzles. A controller is configured to reduce an amount of ink to be ejected to a pixel at an end portion of an image on one side in the arrangement direction from a nozzle array of the plurality of nozzle arrays having a nozzle protruding to the one side the most among the nozzles of the nozzle arrays for a same ejection target pixel. | 12-26-2013 |
20130342599 | INKJET PRINTER - A controller is configured to determine nozzles to be used for ejection in nozzle arrays in a upstream head block by selecting endmost nozzles from nozzles in a region of the upstream head block overlapping a downstream head block so that the endmost nozzle of the nozzle array located more downstream is closer to a center of the upstream head block, and determine nozzles to be used for ejection in nozzle arrays in the downstream head block by selecting endmost nozzles from nozzles in a region of the downstream head block overlapping the upstream head block so that the endmost nozzle of the nozzle array located more upstream is closer to a center of the downstream head block. | 12-26-2013 |
20150070426 | INKJET PRINTER - Positions of a plurality of nozzles of at least one first nozzle array of a plurality of nozzle arrays and positions of a plurality of nozzles of at least one second nozzle array of the plurality of nozzle arrays other than the at least one first nozzle array are offset from one another in a nozzle arrangement direction. A controller is configured to control ejection timings of ink from the plurality of nozzle arrays such that dots of the ink of the colors for each same pixel are offset from each other by an equal offset amount in the nozzle arrangement direction and a relative movement direction orthogonal to the nozzle arrangement direction. | 03-12-2015 |
20150077453 | INKJET PRINTING APPARATUS - A controller determines a correspondence relationship among nozzles in a plurality of nozzle arrays in each head unit so that a positional relationship among nozzles corresponding to the same pixel in each nozzle array becomes the same in all of the head units irrespective of a positional relationship between nozzles having the same number in order from one side in a main scanning direction in two nozzle arrays in each head unit. | 03-19-2015 |
20150281631 | PROJECTION-TYPE VIDEO DISPLAY APPARATUS - A projection-type video display apparatus includes: a light source; an illumination optical system; a video display device; and a projection optical system, and the illumination optical system includes: a multireflection device which makes a distribution of light from the light source uniform; a color wheel which decomposes a color of light from the multireflection device; and a lens which enlarges light from the color wheel. When two orthogonal axes on a plane perpendicular to a traveling direction of the light are respectively defined as an X axis and a Y axis, a curvature radius of the lens in an X-axis direction differs from a curvature radius of the lens in a Y-axis direction. An aspect ratio of an emission surface of the multireflection device is larger than an aspect ratio of the video display device. The lens may be a cylindrical lens or a toroidal lens. | 10-01-2015 |
20150330591 | VEHICLE LAMP - A vehicle lamp includes a phosphor which receives laser light (excitation light) emitted from a semiconductor light-emitting element to emit visible light, a reflector which reflects the visible light (illumination light) emitted from the phosphor forward, and an absorbing member which absorbs excitation light regularly reflected by a surface of the phosphor. A metal plate on which the phosphor is disposed to be inclined to cause the excitation light regularly reflected by the surface of the phosphor to be incident on the absorbing member. An upper end portion of the reflector is disposed at a position lower than a vertical position of the phosphor to prevent the regularly reflected excitation light from being incident on the upper end portion. | 11-19-2015 |
20160001569 | INKJET PRINTING APPARATUS - An inkjet printing apparatus includes a control unit which, in order to reduce a failure of an air pump, when starting ink circulation, executes preparatory processing of feeding ink from the pressurizing tank toward the inkjet head by applying a positive pressure to a pressurizing tank by an air pump in a state in which the pressurizing tank is sealed by a pressurizing-side atmospheric air opening valve and a negative-pressure tank is opened to the atmosphere by a negative-pressure side atmospheric air opening valve; and feeding ink from the negative-pressure tank to the pressurizing tank by the ink pump until the liquid level height of the negative-pressure tank reaches less than a reference height. | 01-07-2016 |
20160084461 | VEHICLE LAMP - Provided is a vehicle lamp for emitting illumination light having reduced color nonuniformity and luminance variation with a simple structure. The vehicle lamp comprises: a light source for emitting excitation light; a fluorescent body for emitting fluorescent light excited by the excitation light emitted from the light source; a diffuser for diffusing the excitation light specularly reflected on the surface of the fluorescent body; and a reflector for reflecting the fluorescent light emitted from the fluorescent body and the excitation light diffused by the diffuser ahead of a vehicle. The fluorescent body is arranged above the light source, and the reflection surface of the reflector is arranged to face the fluorescent body from the direction in which the light is specularly reflected on the fluorescent body toward the lower side of the fluorescent body. | 03-24-2016 |
