20090023090 | SUPPORT FOR IMAGE RECORDING MATERIAL, METHOD OF PRODUCING THE SAME, AND IMAGE RECORDING MATERIAL AND IMAGE RECORDING METHOD USING THE SAME - The present invention provides a support for image recording material etc. that can record high-quality images far from occurrences of blister, uneven recording or uneven fixing. | 01-22-2009 |
20090073566 | OPTICAL SHEET FOR DISPLAY UNIT AND MANUFACTURING METHOD THEREOF - In a manufacturing method of the present invention, a diffusion sheet having a flat size of a product size or more is laminated to a front surface and/or back surface of a lens sheet having flat size of the product size or more, and the stack is cut along its periphery into the product size, and the lens sheet and the diffusion sheet are bonded to each other at least one or more peripheral points thereof. This eliminates a step for individually cutting a number of films (sheets) into a product size, and a step for aligning the number of films (sheets) for lamination. In addition, the method does not cause a problem of waste of protective sheets, but provides advantages in both cost and quality. There is no problem caused in laminating a number of films, or problems caused by different thermal expansions/thermal shrinkages of a plurality of films. | 03-19-2009 |

20090086505 | PLANAR LIGHTING DEVICE - The planar lighting device includes, in addition to light sources, a light exit plane, a pair of light entrance planes formed on a pair of sides of the light exit plane, and a rear plane composed of a pair of inclined planes formed on a side opposite from the light exit plane such that the light guide plate grows thicker with an increasing distance from the light entrance planes toward the center. The light guide plate contains light scattering particles satisfying Npi>Np, where Npi is the particle density in a region of space within a given range of the light guide plate and Np the density in the other region of space. The planar lighting device with minimized brightness unevenness liable to develop near the light entrance planes when the light exit plane has great dimensions. | 04-02-2009 |
20090294998 | Method and Apparatus for Producing Embossed Sheet - A method of producing an embossed sheet includes the steps of allowing a flexible strip-shaped sheet to continuously travel, forming a coating layer by coating the surface of the sheet with a radiation curable resin, transferring a pattern of concavities and convexities on the surface of the emboss roller to the coating layer by winding the sheet around the rotating emboss roller, curing the coating layer by irradiating the sheet which is wound around the roller with radiation, releasing the sheet from the emboss roller, laminating a protective film on one or both sides of the continuously traveling sheet after releasing, and taking up the continuously traveling sheet after lamination in the form of a roll. According to the method, a high quality, defect-free embossed sheet having a fine regular pattern of concavities and convexities on the surface can be produced at high line speed with high productivity. | 12-03-2009 |
