Patent number: 7922947Abstract: A solvent and TAC particles are continuously supplied to a disperser. When the shearing of the solvent and the particles are made in a shearing section, the particles are dispersed in the solvent. The dispersion is fed to a mixer in one minute. The shearing of the dispersion is made in the mixer, the particles are swollen in the solvent in one minute. Since the shearing and the continuous feed of the swelling solution is made, the aggregation does not occur. There are no undissolved aggregates in a dope, which is obtained from the swelling solution. A film produced from the dope has no defects of luminescent spot but excellent optical properties.Type: GrantFiled: September 23, 2004Date of Patent: April 12, 2011Assignee: Fujifilm CorporationInventor: Yukihiro Katai

Patent number: 7892470Abstract: A casting film is formed by casting a dope containing a polymer and a solvent onto a support. Thereafter, the casting film is peeled off from the support as a wet film (74). The wet film (74) is transported to a tenter device (47) having plural tenter clips (101). Before holding side edges of the wet film (74) by the tenter clips (101), air is blown from an outlet (120a) of an air nozzle (120) to a curled portion (74a) such that the air is pressed against the curled portion (74a). Thereby, the curled portion (74a) is flattened to become an approximately flat portion (74b).Type: GrantFiled: September 26, 2006Date of Patent: February 22, 2011Assignee: Fujifilm CorporationInventor: Kentarou Tanimura

Patent number: 7887725Abstract: Dope is discharged onto the peripheral surface of a rotating casting drum to form a casting bead. A decompression chamber decompresses an upstream side from the casting bead in a moving direction of the casting drum. The decompression chamber includes a sensor unit for detecting a width of the casting bead. A control section shifts outer side seal plates in the width direction based on the width data, such that the outer side seal plates are located in an upstream side from side ends of the casting bead. Upon formation of a casting bead having a new width, the control section shifts the outer side seal plates based on the new width such that the outer side seal plates are located in the upstream side from the side ends of the casting bead having the new width.Type: GrantFiled: March 2, 2009Date of Patent: February 15, 2011Assignee: FUJIFILM CorporationInventor: Akinori Ochiai

Patent number: 7871549Abstract: A polymer solution (21) is prepared by dissolving poly-.?.-caprolactone and amphipathic polyacrylamide in an organic solvent. The polymer solution (21) is cast from a casting die (25) onto a casting belt (26) to form a casting film (40). Air (35) from a blowing and suctioning device (34) is sent to the casting film (40) to generate droplets (44). The relative speed of drying air (37) to the moving speed of the casting belt (26) is adjusted at 5 m/min in parallel flow. The water in the drying air (37) is condensed in the casting film (40) to form the droplets (44). The droplets (44) are evaporated after evaporating the organic solvent in the casting film (40), so that a honeycomb-structure film (12) can be obtained.Type: GrantFiled: August 3, 2005Date of Patent: January 18, 2011Assignee: FUJIFILM CorporationInventors: Hidekazu Yamazaki, Koju Ito
