摘要： A dipping bath contains a polymer solution. Stent body members are dipped into the polymer solution. The polymer solution forms membrane on the surface of the stent body member. Humid atmosphere is created around the stent body members with the membrane to condense water vapor into water droplets on the surface of the membrane. After growing the water droplets to water drops, a solvent is evaporated, and the water drops penetrate into the membrane. Then, the water drops are evaporated with leaving pores in the membrane. The water drops function as templates.

摘要： In a coating zone, a cylindrical tube is soaked in and taken out from a solution, such that a coating film is formed on a curved surface of the tube. In a wet gas zone, while a first gas feeding nozzle having a gas outlet moves in a state where the gas outlet faces an outer peripheral surface of the tube, wet gas is blown toward the coating film through the gas outlet. Water drops are generated on the coating film and grown up. In a dry gas zone, as in the case of the first gas feeding nozzle, while a second gas feeding nozzle having a gas outlet moves, dry gas is blown toward the coating film through the gas outlet. Solvent and water drops are evaporated from the coating film. Pores form from the water drops as a template for the porous material on the coating film.

摘要： A hydrophobic liquid containing a dispersion medium and fine particles is prepared. The fine particles have insolubility of a certain level in a predetermined liquid having a hydrophobic character. The hydrophobic liquid is applied to a support to be a film thereon. Wet gas is blown to the film. Water vapor is condensed from ambient air on a surface of the film to generate water drops thereon. A dispersion medium evaporating gas is blown to the film, such that the dispersion medium is evaporated from the film. A water drop evaporating gas is blown to the film, such that the water drops are evaporated from the film. Accordingly, the water drops function as the template for forming pores, such that the pores are formed on a micro protrusion-depression structure constituted by the fine particles.

摘要： A solution of polymer uniformly dissolved into a solvent is prepared in a solution preparing step. The solvent contains good and poor solvent components for the polymer. The solution is discharged from a coating die to a support to be a coating film thereon in a primary body forming step. A water drop generating step and a fluidity decreasing step are performed in parallel with each other while wet air is applied to the coating film. Water drops are generated on a surface of the coating film in the water drop generating step. The good solvent component is evaporated from the coating film to decrease fluidity of the solution for forming the coating film in the fluidity decreasing step. In the water drop evaporating step, dry air is applied to the coating film. The solvent and the water drops are evaporated from the coating film to obtain the porous film.

摘要： A second liquid is applied to a support and dried to form a middle layer. Then, a first liquid is applied to the middle layer. A third liquid is applied to a film of the first liquid using an inkjet type liquid supply unit to form a porous area. The first and third liquids differ in interfacial tension against water. Moist air is supplied to the porous area to cause condensation. In a third chamber, the condensation grows into large droplets, and a solvent is evaporated from the film. Thereafter, the droplets are evaporated from the porous area. Thus, a porous film in which a plurality of pores are arranged is produced. Since the porous area is formed by inkjet printing method, size, shape, and conditions of the porous area is easily changed.

摘要： A primary dope containing a polymer, a solvent and an additive is fed to a filtration device in a filtrating unit. The filtration device includes a filter on which a deposit layer of a filtration aid is formed, and impurities in the primary dope are adsorbed to the deposit layer. After the filtration, a residue containing the impurities and the filtration aid on the filter, and the filtration device is filled a cleaning liquid. Then a stirrer in the filtration device is stirred so as to disperse the residue to the cleaning liquid. Thus a slurry liquid is obtained and fed to a separation device. In the separation device, the slurry liquid is fed into a strainer to separate the slurry liquid to the residue and the liquid material. The residue is dried in a drying device and the solvent vapor is recovered.

摘要： A dope containing a retardation controller, cellulose ester, and a solvent is prepared. In a first film producing apparatus, the dope is cast onto a casting drum whose surface is cooled to form a casting film in a gel state. The casting film is peeled off from the casting drum, and the peeled casting film is dried until a residual solvent amount reaches 10 wt. %. Cellulose ester contained in the casting film is crystallized by heating the casting film to a temperature of not less than 170° C. and not more than 250° C., and the casting film is stretched in the width direction. Thus, a film is produced. An absolute value |P1| of a degree of orientation of the polymer in the in-plane direction of the produced film satisfies 0≦|P1|≦0.050.
