摘要： 1,112,611. Lateral stretching of plastic films. M. WATANABE. 17 June, 1965 [31 Aug., 1964; 1 March, 1965 (3)], No. 25605/65. Heading B5B. Plastic films are hydraulically stretched laterally while moving longitudinally through a liquid bath by creating liquid currents in the vicinity of the film surfaces moving outwards towards the side edges of the film. Viscose film may be laterally stretched in this way in the coagulating and regenerating bath or other material may be stretched, e.g. in a warm water bath. The hydraulic lateral stretching may be combined with mechanical lateral stretching by passing the film over a bowed bar and longitudinal stretching may be reduced by inducing longitudinal liquid flow in the direction of travel of the film in the vicinity of the film surfaces. In Fig. 1 viscose is extruded from hopper 9 into regenerating bath 2 and passes through several hydraulic stretching devices P, Q, R before emerging from the bath. Each device consists of a pair of units each embracing a side portion of the film and consisting of a pair of plates 20, 21 or other members defining a narrow space through which the film 11 passes. Liquid is drawn through the spaces M, N between the plates 20, 21 and the film towards the edge of the film into suction bore 17 and hence out of the bath to which it is returned, after conditioning, through pipe 3. Liquid flow is controlled and the position of the film in the flow space stabilized by grooves 22, 23 on the inner surfaces of the plates 20, 21 and by holes through these plates through which liquid flows on to the film as well as from the peripheral regions of the plates. The units may be adjustable sideways of the film to accommodate films of different widths, Figs. 7 and 10 (not shown), and the space between the plates may be increased in the immediate vicinity of the edges of the film or alternative means employed to prevent slight variations in film width from affecting the magnitude of the stretching force generated, Figs. 23-25 (not shown). Pairs of units may be joined by plates with a relatively wide spacing between which longitudinal liquid flow is induced by gravity or suction in the direction of travel of the web to reduce the longitudinal stretching caused by viscous drag, Figs. 20-22 (not shown). The stretching units may be curved, as at R. With sharp curves it is necessary to feed liquid under pressure to the space within the stretching unit next to the concave face of the film, Fig. 10 (not shown). Between a pair of units R the film may pass round a bowed bar, Fig. 19 (not shown), to provide some mechanical lateral stretch. Liquid level of the bath 2 is maintained constant by a weir 5.

摘要： The present invention relates to an optical fiber having a large positive dispersion in a wavelength band of 1.55 &mgr;m in order to compensate for a negative dispersion inherent in an NZ-DSF in the wavelength band of 1.55 &mgr;m. This optical fiber comprises a depressed cladding structure constituted by a core region; an inner cladding, disposed at the outer periphery of the core region, having a lower refractive index; and an outer cladding having a higher refractive index. In this optical fiber, the relative refractive index difference of the core region with respect to the outer cladding is at least 0.30% but not greater than 0.50%, and the relative refractive index difference of the inner cladding with respect to the outer cladding is at least −0.50% but not greater than −0.02%. Also, the optical fiber has a dispersion greater than 18 ps/nm/km at a wavelength of 1.55 &mgr;m, and an effective cross-sectional area Aeff of at least 70 &mgr;m2 at the wavelength of 1.55 &mgr;m.
