Electroluminescent devises consisted of two layers, a hole injecting diamine layer and an emitting Tb3+ complex of acetylacetonate layer, were fabricated by vacuum deposition. The EL cells exhibited characteristic bright Tb3+ luminescence with high efficiency at low drive voltage.
We succeeded in tremendous enhancement of torque density as well as power density in High Temperature Superconducting Induction/Synchronous Machine (HTS-ISM) for next generation transportation equipments. First, we fabricated and tested the 20 kW-class prototype as the validation of our design concept (1 st generation). And then, the 70% reduction of the motor's volume is challenged with the same power (2 nd generation). We successfully realized the tremendous enhancement of the torque density, and further the overload tolerance was also realized at the steady state.
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.
