As a result, illumination light quality is avoided from being reduced by appearance of conspicuous ring-like bright part. In addition, uniform illumination light can be supplied to a broad angle range. Even if a plurality of point-like-light-sources are arranged at intervals, respective light fluxes originated from respective point-like-light-sources are well mixed. | 05-07-2009 |
20090078074 | Resin Double Helical Gear and Gear Train Using Same - There are provided a resin double helical gear capable of reducing operation noises and vibrations of an image forming system, such as an ink jet printer, which is arranged in the vicinity of an operator, and a gear train using the same and having a smaller number of parts. The gear train | 03-26-2009 |
20090052192 | Light emitting device and lighting device having the same - A light-emitting device ( | 02-26-2009 |
20080298060 | Illumination device and illumination unit - Light from a LED (point-like light source) is expanded smoothly to a desirable range at a high efficiency by a light flux control member. The light flux control member is provided with a lens portion located at a part corresponding to the LED and a mount portion (body portion) detachably supporting the lens portion. The lens portion has a back face provided with a recess located as to correspond to the LED. The recess expands light from the LED smoothly and efficiently to a broad range, bringing an emission from a front face (fore face) toward a wide range. A member-to-be-illuminated supplied with the emission is illuminated uniformly. LEDs and recesses are made enable to be arranged flexibly without need of an increased number of molds. | 12-04-2008 |

20080276742 | Resin Double Helical Gear and Gear Train Using Same - There are provided a resin double helical gear capable of reducing operation noises and vibrations of an ink jet printer, and a gear train for an ink jet printer using the same. The gear train | 11-13-2008 |
20080260591 | SAMPLE HANDLING UNIT APPLICABLE TO MICROCHIP, AND MICROFLUIDIC DEVICE HAVING MICROCHIPS - After a second plate member | 10-23-2008 |
20080232137 | Light guide plate, surface light source device and image display - A light guide plate has an incidence face provided by a side end face, emission face and back face. The incidence face has first and second end edges meeting the emission face and the back face respectively. First range N | 09-25-2008 |
20080229852 | SPRING REACTION FORCE CONVERTING APPARATUS - A spring reaction force converting apparatus has first and second members arranged to be in parallel with and opposed to each other and to be capable of being moved toward and apart from each other, a spring element arranged to be extended between the first and second members in parallel thereto, a link mechanism holding the spring element between the first and second members such that the spring element is capable of being expanded and contracted, the link mechanism being connected to the first and second members; a stopper member maintaining the spring element held by the link mechanism in a condition in which the spring element is compressed by a predetermined amount in an initial condition, and an arrangement thereof in which a reaction force of the spring element is converted to a different type of force transmitted to the first and second members through the link mechanism. | 09-25-2008 |
20080204631 | Surface light source device and display - Overlapping first and second light guide plates have incidence faces located opposite to each other. Each light guide plate has an emission restraint region, an emission gradually-increasing region and an emission promotion region arranged in order from incidence face toward distal end face. In each emission gradually-increasing region, emission light quantity increases gradually away from each emission restraint region toward each emission promotion region. The emission gradually-increasing regions of the light guide plates overlap each other. The emission promotion region of the second light guide plate overlaps with the emission restraint region of the first light guide plate while the emission restraint region of the second light guide plate overlaps the emission promotion region of the first light guide plate. Light from LEDs is limited by windows. Color-mixing of the LED-light occurs in each emission restraint region to become whitened light gaining emission intensity in the emission promotion regions. | 08-28-2008 |
