摘要： A phase retarder comprises one cellulose ester film. The retardation value of the film represented by Re450 measured at the wavelength of 450 nm is in the range of 100 to 125 nm. The retardation value of the film represented by Re590 measured at the wavelength of 590 nm is in the range of 120 to 160 nm. The retardation values represented by Re450 and Re590 satisfy the condition of Re590−Re450≧2 nm. An aromatic compound having at least two aromatic rings is incorporated in the film as a retardation increasing agent to obtain λ/4 in the wide wavelength region defined above. A phase retarder can also give λ/2 in a wide wavelength region in the same manner.

摘要： An extrusion die is provided with a male die through which a billet is extruded from an upstream side to a downstream side and, the male die adapted for forming an inside shape of a hollow material; and a female die for holding the male die and forming an outside shape of the hollow material. The male die is formed of a spider and a holder for holding the spider. The spider is formed of a mandrel and a plurality of bridge parts for supporting the mandrel, and enabling a distal-end outer peripheral surface to engage with a bridge-holding surface. The distal-end outer peripheral surface of each of the bridge parts and the bridge-holding surface of the holder are joined by shrink-fitting.
