| 20100024577 | RESIN MATERIAL MEASURING METHOD AND RESIN MATERIAL MEASURING APPARATUS - A resin material measuring method which obtains a prescribed amount of a resin material by measuring liquid resin material, the resin material measuring method including: charging the resin material having a fluidity into an internal space of a cylinder using a cylinder-piston mechanism which includes: the cylinder having a discharge aperture at one end and the internal space being constant in cross-sectional area; and a piston which is inserted in the internal space; determining a necessary movement stroke length of the piston corresponding to the resin material of a prescribed volume according to a relationship between the volume of the resin material and the cross-sectional area and the movement stroke length; discharging the resin material from the cylinder through the discharge aperture by moving the piston by the determined movement stroke length; and cutting the discharged resin material from the resin material located inside the cylinder. | 02-04-2010 |
| 20100041807 | OPTICAL MEMBER MANUFACTURING METHOD, OPTICAL MEMBER MANUFACTURING APPARATUS AND OPTICAL MEMBER - A method for manufacturing an optical member from a powdery nano composite material, which includes a thermoplastic resin containing inorganic fine particles, is provided. The method includes: preparing an aggregated intermediate body by heating the powdery nano composite material; and forming the optical member having a finished shape by heat-press molding the intermediate body. | 02-18-2010 |
| 20100104855 | PREFORM MANUFACTURING METHOD, PREFORM MANUFACTURING APPARATUS, PREFORM AND OPTICAL MEMBER - A method for manufacturing a preform from a nano composite resin that includes a thermoplastic resin containing inorganic fine particles, the preform being a pre-finish product of an optical member having an optical surface formed by press molding, is provided. The method includes: supplying a solution including the nano composite resin and a solvent into a mold which has an approximate optical surface closely resembling the optical surface and an opening to an atmosphere; and evaporating the solvent while a shape of the approximate optical surface is kept, to solidify the solution. | 04-29-2010 |
