In the flux applying device, a control portion controls conveying rollers or the like so that thickness of flux applied to solder is controlled. The winding roller rotates so that the solder is conveyed at the conveying speed. The drawing-out roller applies any load (back tension) to the solder backward along the conveying direction of the solder when drawing out the solder. The solder is conveyed at the predetermined speed and dipped into the flux tank containing flux. The solder is pulled up from the flux tank at the conveying speed vertically. By pulling up the solder from the flux tank at the constant conveying speed vertically, the interfacial tension acts on the solder 9a and the flux, so that the flux having a uniform thickness according to the conveying speed remains on the surface and back surface of the solder.

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.
