摘要： PURPOSE:To enlarge gas permeation characteristics and to attempt to improve membrane characteristics by placing a plurality of hollow separation membranes with separation function therein along the longitudinal direction of a fibrous body consisting of a porous layer with reinforcing function and laminating a porous layer with reinforcing function on the inner surface of a separation membrane. CONSTITUTION:A plurality of hollow separation membranes B with separation function therein along the longitudinal direction of a fibrous body consisting of a porous layer A with reinforcing function exist and a porous layer C with reinforcing function is laminated on the inner surface of a separation membrane. Gas permeation characteristics is made thereby about 3.8 times larger than the conventional composite membrane even when the outer diameters and the fine pore structures of the porous layers A and C and the thickness of the separation membrane B are the same as those for the conventional composite membrane and the membrane characteristics can be improved by increase in the membrane area of the separation membrane B. In addition, it is possible to miniaturize furthermore various membrane modules wherein the conventional composite membranes are used by using this multifilament type hollow fiber composite membrane.

摘要： PURPOSE:To enhance resolution of a refractive index distribution type rod lens by a simple method by press-bonding a plastic fiber to a rough surface, and transferring the surface to the fiber. CONSTITUTION:A plastic fiber is press-bonded to a rough surface, and the surface is transferred to the fiber to treat an outer periphery of the fiber. A method for transferring the surface to a side of the fiber has a method for rotating a plastic fiber while press-bonding the fiber to a rough surface such as a metal gauze, sandpaper, etc., a method for feeding a plastic fiber in particular object such as sand, etc. When the rough surface is transferred, it is desirable to heat the fiber. More specifically, it is desirable to heat it to 50 deg.C or higher and further desirable to heat it to glass transition temperature (Tg) or higher of the fiber.

CONSTITUTION:In the case of employing light transmission resin and light non-transmission resin as first resin, extrusion molding machines 1, 2, 3 are comprised of a first extruding machine 1 for light transmission resin, a second extruding machine 2 for light non-transmission resin, and a third extruding machine 3 for resin having incompatibility with the first resin. The resin melted by each extruding machine is passed through fixing pumps 4,5,6 and passageways 9,10,11, thereby forming the layer of a base material with recessions and protrusions in its surface that becomes a main passageway from a first nozzle 12. Next, light non-transmission resin B is supplied to a second nozzle 13, and on a predetermined place of the recession and protrusion parts formed on light transmission resin A, a light insulating layer or a out-light absorbing layer is formed. Furthermore, by resin C having incompatibility with the first resin supplied by the third nozzle 14, the recession and protrusion surface is covered. In the next place, the resin A, resin B, and resin C are co-extruded simultaneously from a discharging nozzle 15 and made into a three-layered sheet. Thereafter, the resin C is separation-removed therefrom by a separating device 16.
