A nanosynthesis apparatus includes an outer tube and an inner tube with surfaces that oppose each other across a gap as part of a reaction chamber. A deposition fluid flows along the reaction chamber to grow nanostructures such as graphene or carbon nanotubes on a substrate in the reaction chamber. The reaction chamber may have an annular cross-section, and the growth substrate may wrap around the inner tube in a helical manner. This configuration can allow a flexible film substrate to travel through the reaction chamber along a path that is significantly longer than the length of the reaction chamber while maintaining a uniform gap between the substrate and the reaction chamber wall, which can facilitate a uniform temperature distribution and fluid composition across the width of the substrate.

A manufacturing apparatus of a long fiber composite material according to an exemplary embodiment of the present invention includes: a main body where an inlet through which a plurality of fiber bundles are penetrated is formed at one side and an outlet through the fiber bundles are discharged is formed at the other side; a plurality of first through-hole plates that are arranged in parallel with each other along a first direction in the main body and having a plurality of through-holes through which the plurality of fiber bundles are penetrated formed therein; and a second through-hole plate that is disposed between a pair of first through-hole plates that are adjacent to each other among the plurality of first through-hole plates, and through which the plurality of fiber bundles penetrated through the first through-hole plates are penetrated.

An apparatus for processing yarns includes a first roller set for extending yarn bean; a node generator installed after the first roller set for forming node section of the yarn beam; a first cleaning chamber installed after the node generator for cleaning the yarn beams; a material chamber for adding additive to the yarn beam; a second roller set installed after the material chamber for extending the yarn beam; a first heating chamber installed after the second roller set for thermally setting additives to the yarn beam so that the additives are firmly secured to the yarn of the yarn beam; a third roller set installed after the heating chamber for controlling the heating time of the yarn beam in the first heating chamber; and a fourth roller set installed after the third roller set for winding the yarn beam to a desired shape.

A dipping bath according to the present disclosure includes a body to hold a slurry for dip coating, an inlet installed to flow the slurry from an outside of the body to an inside, and an outlet installed to discharge the slurry from the inside of the body to the outside, and one end of the inlet placed inside the body may be disposed facing a side surface of the body at a distance and may be tilted to a predetermined angle in a direction toward a bottom surface of the body. According to the present disclosure, adjustment of an incidence angle of the slurry flowing into the bath through the inlet may increase a flow rate of the slurry toward the bottom surface, as well as allowing a uniform distribution of solids contained in the slurry circulating through the bath.

Web lifter and/or stabilizer and method of lifting and/or stabilizing a travelling web and for coating a web. The device creates a web hold down force via a negative pressure slot at its exit side, which draws the web down against the surface on the entry side. The device can be actuated to move the web relative to a slot die coater off the die lips and stop the application of slurry to the web, thereby creating uncoated regions on the web surface. The device can then be actuated to move the web back into contact with the coater to start the application of slurry to the web, thereby creating coated regions on the web surface. Web lifting can be accomplished by rotating the device in first and second directions to lift the web off of the slot die coater and return the web back into contact with the coater.
