| 20090302003 | Aqueous Solution for Chemical Polishing and Deburring and Process for Polishing and Deburring A Part made of Pure Nickel or Nickel-200 Therein - An aqueous solution for polishing and deburring includes pure water; carboxylic acid of 200 gram per liter to 300 gram per liter; sulfuric acid ions of 200 gram per liter to 500 gram per liter; phosphoric acid ions of 100 gram per liter to 300 gram per liter; and nitric acid ions of 50 gram per liter to 200 gram per liter. Also, a process for polishing and deburring a part made of pure nickel or nickel-200 in the solution includes removing oily substance from the part; washing the part by water; pouring the solution into a bath and submerging the part in the solution so that the part is brought into contact with the solution; neutralizing the solution remained on the surface of the part to prevent the part from oxidizing; and drying the part to obtain a finished part. | 12-10-2009 |

| 20110234580 | OPTICAL SUBSTRATES HAVING LIGHT COLLIMATING AND DIFFUSION STRUCTURES - An optical substrate having a structured prismatic surface and an opposing structured lenticular surface. The structured lenticular surface includes shallow-curved lens structures. Adjacent shallow-curved lens structure may be continuous or contiguous, or separated by a constant or variable spacing. The lens structure may have a longitudinal structure with a uniform or varying cross section. The lenticular lenses may have a laterally meandering structure. Sections of adjacent straight or meandering lenticular lenses may intersect or partially or completely overlap each other. The lenticular lenses may be in the form of discontinuous lenticular segments. The lenticular segments may have regular, symmetrical shapes, or irregular, asymmetrical shapes, which may be intersecting or overlapping, and may be textured. The lens structure may be provided with isolated ripples, in the form of a single knot, or a series of knots. | 09-29-2011 |
