摘要： Provided is a method for manufacturing an optical film, which manufactures a transparent optical film controlled to have a little changes in retardation even after a humidity and heat durability test. A second tender (20) includes a preheat area (45), a first stretch area (46), a second stretch layer (47), and a cooling area (48) in order from the upstream side of the returning direction (Z1). The first stretch area (46) maintains the temperature of the film in a range from (Tg+10°C) or more to (Tg+50°C) or less. The first stretch area (46) stretches the film (12) in the width direction to widen the width to one and a half times or more. The second stretch area (47) stretches the film (12) in the width direction to a stretch angle (theta2) smaller than the stretch angle (theta1) of the first stretch area (46).

摘要： PURPOSE: A method and an apparatus for fabricating a clad pipe for plastic optical fiber, a clad pipe fabricated thereby, and a plastic optical fiber fabricated by a clad pipe are provided to enhance the productivity by restraining unevenness on an inner surface of the clad pipe and increasing an extruding speed. CONSTITUTION: A method for fabricating a clad pipe for plastic optical fiber includes a process for cooling an inner surface of the clad pipe(27) in an extruding process by a melting extruding machine before an extruded resin is crystallized at a temperature less than a melting point of the extruded resin. The extruded resin is formed with a fluorine resin. The fluorine resin includes at least polyvinylidene fluoride. In the process for cooling an inner surface of the clad pipe in an extruding process, gas or liquid are injected into the inner surface of the clad pipe.

摘要： PURPOSE: An optical film manufacturing method is provided to effectively compensate the deviation of a delayed-phase axis and thus to produce an optical film with a greater width. CONSTITUTION: An optical film manufacturing method is as follows. A long polymer film is heated to be stretched in a width direction(Z2). The polymer film is heated with the width restricted, thereby relieving the internal stress of the polymer film. The deviation of the delayed-phase axis of a lateral end(12s) of the polymer film from the target delayed-phase axis is calculated. The lateral end of the polymer film is heated according to the calculated deviation, thereby compensating the deviation.

摘要： PURPOSE: An optical film manufacturing method is provided not to use a specific compound such as a retardation increasing agent. CONSTITUTION: A single layer dope flow (80) is overlapped with a Y direction on an XY plane and is compressed to reduce the thickness of the dope flow. A first layer-shaped dope flow (81) compressed to a thickness direction passes through a layer forming process. The first layer-shaped dope flow is converted into a second layer-shaped dope flow (82) by compressing the flow thickness of each layer. The second layer-shaped dope flow is converted into a third layer-shaped dope flow (83) by compressing the flow thickness of each layer.
