Abstract: The invention provides a power supply including at least one power output port, at least one status alert component, and at least one output port status monitoring module. The status alert component generates at least one visual prompt based on an alert signal. The output port status monitoring module includes at least one temperature sensor adjacent to the power output port, a microcontroller connected to the temperature sensor and sensing an output current from the power output port, and a reset signal generator connected to the microcontroller. The microcontroller comprises at least one port status alert condition that takes a temperature and the output current of the power output port as decision factors. The microcontroller outputs the alert signal to the status alert component when the port status alert condition is met and maintains the status until a reset signal provided by the reset signal generator is received.

Abstract: An Hg- or Nd-based oxide superconductor comprises Ba as a constituent element and has a content of carbon as an impurity at a level of not greater than 2.0 atomic % whereby the oxide superconductor stably shows high superconducting characteristics without causing degradation with time. For its production, BaO, which has a reduced content of carbon impurity of 0.5% or below, is provided as a feed stock for Ba, and the starting materials are mixed and processed in a dry atmosphere wherein an amount of a carbon-containing gas is suppressed to a certain level, thereby obtaining the oxide superconductor.
