We applied an infrared-(IR-) laser-assisted chemical vapor deposition technique to YBa 2 Cu 3 O 7−δ (YBCO) film fabrication in order to enhance the deposition rate to one suitable for commercial applications. IR-laser illumination during deposition effectively suppressed outgrowth of a-axis oriented grains, which strongly diminish the film's current-carrying capacity. As a result, high-performance YBCO films with critical current densities of greater than 1 × 10 6 A cm −2 were successfully obtained at high deposition rates of up to 58 µm h −1 (∼1 µm min −1 ) by this method.
The micro −CNC −incremental forming syst ¢ m fbr foil materials was developed as a microfactory cell . The principle of this flexib 且 e sheet metal forming systern is called incremental forming by hammering , Small increments of sheet metal bending and bulging deformation are generated by hammering . Repeated step ・ by −step cycles resu 且 t in variously shaped shetl structures without dies . To reaHze these systems , small actuators , such as piezoelectricactuat rs , small linear sensors , and an X − Ystage driven by ultrasonic ] inear motors , are selected .

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
