摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a plastic optical member with excellent productivity by which a hollow tube having one end sealed can be stably produced, and to provide a plastic optical member obtained by the method. SOLUTION: The method for manufacturing a plastic optical member is carried out by injecting a polymerizable monomer composition into a plastic hollow tube and polymerizing the composition in the hollow tube. The method features that before injecting the composition, one end of the hollow tube is sealed with resin. Preferably, the one end of the hollow tube is sealed with resin having a different composition from that of the plastic material constituting the tube. COPYRIGHT: (C)2003,JPO

摘要： A non-birefringent optical resin material is composed of a resin material and inorganic fine particle material birefringence sign of which are the same. A molten resin material, which contains an inorganic fine particle material, dispersed therein, of the same birefringence sign as that of the resin material, is caused to flow into a mold 4 through a gate 5. The molten material flows as to expand radially. Velocity vector of the flow has normal components P, R in addition to straight- ahead component S. Bonding chains of the resin material are generally orientated to the direction of velocity vector. In the vicinity of points A, B on an equiphase face 7, bonding chains of the resin material are generally orientated to lines extending from the exit of the gate 5 to point A and B, respectively. Flowing velocity has a gradient around each fine particle, causing the fine particle to be influenced by a moment and to tend to orientate so that the major axis of the particle is directed approximately parallel to equiphase faces 6 to 9 of the flow. On the whole material, this cancels birefringence.

摘要： A fluorescent lamp L is arranged in the vicinity of an incidence surface 2 of a light scattering guide plate 1. A prism sheet 4' having rows of prism elements and rows of lens elements on each side is arranged outside an exiting surface 5. The angles of inclination of slopes 4a and 4b satisfy a condition that phi a > phi b. The slopes 4a and 4b extend in the transverse direction of the light scattering guide plate 1, and slopes 4c and 4d extend in the longitudinal direction. A reflector 3 is arranged along a rear surface 6. Light emitted from the exiting surface 5 is efficiently propagated by an inner prism surface toward a forward direction, shifted in the transverse direction by an outer prism surface or the lens element surfaces 4c and 4d, and is then returned inwardly. The path histories of light emitted from the prism sheet 4' is diversified to improve visual characteristics. The peak level of brightness as viewed in the forward direction is improved and brightness is smoothly reduced according to deviation from the peak direction.

摘要： A polymer is inserted into a cylinder (1) and heated, and a pressure is then applied to the polymer so as to extrude the same in the shape of a fiber from a nozzle (3). In the meantime, a diffusible material is injected from a nozzle (5) into the central portion of a molten liquid of this polymer through a thin-tube cylinder (4), and it is diffused gradually from the central portion of the molten polymer to the circumferential portion thereof as it flows toward a discharge port of the nozzle (3). The material extruded from the nozzle (3) is air-cooled and taken up around a drum (7) via a roller (6). The fiber-like molded product provides a distribution of refractive index varying continuously from the center thereof toward the circumferential portion thereof, and serves as a convergent or divergent plastic light transmitter. Conversely, even when the molten liquid of the polymer is extruded from the nozzle (5), a light transmitter having a region in which a refractive index varies continuously can be obtained. A proper number of the cylinders and various kinds of materials to be supplied to the cylinders can be selected.
