    摘要： A process for purifying lysine in a lysine production process, which involves passing a solution containing lysine over a cation exchange resin such that lysine adsorbs onto the resin, eluting adsorbed lysine from the resin with an aqueous solution of ammonia to produce a lysine-containing elution liquid, passing the elution liquid directly to a reverse osmosis membrane system, and concentrating the lysine-containing elution liquid with the reverse osmosis membrane system such that ammonia is selectively removed from the lysine containing elution; the aqueous ammonia which is separated from the lysine may be recycled through the cation exchange resin to regenerate the resin or to elute more lysine from the resin.

    摘要： A mirror surface grinding method processes an optical glass material into a lens shape using a cup-shaped grinding stone. The grinding stone is pupplied with a polishing solution which contains charged fine particles, thereby electrically attaching the charged fine particles to the grinding stone. The grinding stone is rotated and moved relative to the optical glass material along a final shape to be generated from the optical glass material, thereby grinding an unnecessary portion of the optical glass material to remove it, using a peripheral face portion of the grinding stone, and at the same time polishing the final shape surface of the optical glass material using charged fine particles attached to an annular face portion of the rotating and moving grinding stone.
