A hollow fiber membrane module having: a tubular case; a plurality of hollow fiber membranes disposed within the case; sealing and fixing parts that fix the hollow fiber membranes to each other at the ends of the plurality of hollow fiber membranes; and sealing parts that seal annular gaps between the case and the sealing and fixing parts. The sealing parts are bonded to the inner peripheral surface of the case and the outer peripheral surface of the sealing and fixing parts while being allowed to expand or contract in the direction in which the spacing of the gaps between the case and the sealing and fixing parts changes.

The present application provides a method for extracting an extractable component from a feed liquid using a porous membrane. One embodiment of the method includes temperature-swing solvent extraction of water from saline water using a porous membrane.

A hollow fiber membrane module 10 includes: a plurality of hollow fiber membranes 200; a case 100 that accommodates the plurality of hollow fiber membranes 200 and has a case main body 110 made of a resin and having openings at both ends thereof; and a pair of sealing and fixing portions 310 and 320 that seal a gap between the hollow fiber membranes in a state where a hollow inside of each of the hollow fiber membranes 200 is kept open and fix the plurality of hollow fiber membranes 200 to the case 100 on both end sides of the case 100. In the case main body 110, a reinforcement portion 115 that connects a pair of facing wall surfaces of inner wall surfaces for accommodating the plurality of hollow fiber membranes 200 is integrally provided on the pair of wall surfaces.

A stack plate of a stack plate device of a humidifier includes inlay parts extending along two opposing front or longitudinal ends of the stack plate, a semipermeable layer disposed on and being stabilized by the inlay parts, and a frame disposed on multiple portions of the semipermeable layer that are disposed on the inlay parts, the frame circumferentially enclosing a through-opening in the stack plate. A remaining portion of the semipermeable layer completely covers the through-opening. An outer circumferential section of the semipermeable layer and the inlay parts are overmolded by the frame. Opposing front ends of the frame define inflow and outflow regions, respectively, on a first side of the frame for a second fluid, and opposing longitudinal ends of the frame define inflow and outflow regions, respectively, on a second side of the frame for a first fluid.

A humidifier having a housing that extends along an axial direction, the housing having a first inlet, a first outlet, a second inlet and a second outlet, and a membrane unit being arranged in the interior of the housing. The first inlet and the first outlet are in flow connection with each other by means of a first flow path, and the second inlet and the second outlet are in flow connection with each other by a second flow path. The membrane unit is cylindrical and has a plurality of hollow fiber membranes arranged side by side. The membrane unit is outwardly surrounded at least in part by a first chamber, and the first chamber is outwardly surrounded at least in part by a second chamber separate from the first chamber. The first chamber and the second chamber are in flow connection with each other via one or more throttle slots.

The present technology provides microfabricated filtration devices, methods of making such devices, and uses for microfabricated filtration devices. The devices may allow diffusion to occur between two fluids with improved transport resistance characteristics as compared to conventional filtration devices. The devices may include a compound structure that includes a porous membrane overlying a support structure. The support structure may define a cavity and a plurality of recesses formed in a way that can allow modified convective flow of a first fluid to provide improved diffusive transport between the first fluid and a second fluid through the membrane.

An organic EL display panel manufacturing method includes preparing a substrate. The method further includes forming a plurality of organic EL elements on the substrate. The method further includes deaerating a sealing solution with use of a filter that allows only gases to pass through, the sealing solution including an organic electrically-insulating material to which an electrically-conductive substance is added. The method further includes applying the sealing solution after the deaerating above the organic EL elements and thereby forming a sealing layer.

The present invention relates generally to a pulmonary assist device comprising a housing having tapered inlets and outlets to distribute blood evenly over a fiber bundle. The fiber bundle has a relatively low packing density to prevent the formation of clots. The invention is adapted to be used with a pump or without a pump, in which the heart supplies the necessary blood flow. Moreover, the device can be used as a single module or as multiple modules arranged in parallel.

There is disclosed a process and apparatus for treating urine. Urine is contained in a reservoir and contacted with a liquid side of a separation membrane which also has a gas side. A sweep gas flow is generated on the gas side of the separation membrane. Water in the urine is conducted from the liquid side to the gas flow side of the separation membrane, the separation membrane substantially preventing the passage of other components of urine from the liquid side to the gas flow side of the separation membrane. The water conducted to the gas flow side of the separation membrane is entrained in the sweep gas flow.

An oxygen removal system for removing dissolved oxygen from fuel within a fuel system includes a first housing, a second housing, a membrane filter, a piston assembly, and an outlet cap. The first housing extends along a first axis between a first housing first end and a first housing second end. The second housing is disposed about the first housing. The membrane filter is disposed between the first housing and the second housing. The piston assembly has a piston housing that is disposed about the second housing. The piston assembly is arranged to generate a vacuum to remove a fluid from the membrane filter.
