The injection molding machine according to embodiments of the present invention completes the plasticization of the materials under protection of the non-reactive gas and avoids yellowing of a light guide plate (LGP) due to oxygenolysis of the materials. | 03-03-2016 |
| 20160185057 | METHOD OF MANUFACTURING OPTICAL FIBER AND APPARATUS OF MANUFACTURING THE SAME - A method of manufacturing an optical fiber including drawing an optical fiber preform and forming a bare optical fiber, disposing a coating layer formed of a resin on an outer circumference of the bare optical fiber, and curing the coating layer and obtaining an optical fiber is provided. A direction of the bare optical fiber is changed by a direction changer in any position from drawing the optical fiber to disposing the coating layer. In a flow rate of a fluid from a blowout port, an average flow rate or a highest flow rate in an inlet wire portion and an outlet wire portion is higher than a lowest flow rate of the fluid in an intermediate portion. | 06-30-2016 |
| 20160185058 | METHOD AND EQUIPMENT FOR MANUFACTURING LIGHT GUIDE PLATE - In a backlight module, a diffusive structure and a prism structure are replaced by a diffusive prism film formed on a substrate and transferred via In-Mold Decoration by Roller (IMR) to a light guide body via injection molding. A reflection film is also transferred to an opposite side of the light guide body via the same way. In such way, optical films may be readily transferred to the light guide body via two-side IMR during the process of injection molding of the light guide body, saving room taken by substrates of the optical components. | 06-30-2016 |
| 20160187582 | METHOD OF MANUFACTURING OPTICAL WAVEGUIDE DEVICE AND LASER PROCESSING APPARATUS - An optical waveguide having a plurality of optical paths is formed on a substrate. A reflection mechanism is arranged above the optical waveguide. The reflection mechanism includes mirror components, each of which has an inclined reflective surface, and a mask having a plurality of openings. Laser is irradiated to the mirror components and optical path conversion inclined surfaces are formed in the plurality of optical paths at the same time by the laser reflected on the mirror components. | 06-30-2016 |
