Abstract: The present invention provides a pharmaceutical composition for prevention or treatment of a stress disease and depression, the pharmaceutical composition be safely useable without toxicity and side effects by using an extract of leaves of Vaccinium bracteatum Thunb., which is natural resource of Korea, so that the reduction of manufacturing and production costs and the import substitution and export effects can be expected through the replacement of a raw material for preparation with a plant inhabiting in nature.

Abstract: An electric compressor capable of reducing a size and lightening weight of a package of an inverter unit, as a common mode choke (CM choke) is disposed radially outside of a circuit board of the inverter unit, and a high voltage connector, a CM choke, and a low voltage connector are integrated into a support body.

Abstract: The present invention relates to an apparatus and method for measuring the critical current of a superconducting tape. A continuous critical current measurement apparatus for measuring critical current of a superconducting tape while feeding a superconducting tape in a liquid nitrogen container includes wheel-type current terminals and wheel-type voltage terminals. The superconducting tape is continuously supplied and fed by a reel-to-reel device, and the critical current of the superconducting tape is measured in real time using the wheel-type current terminals and the wheel-type voltage terminals while the superconducting tape is fed at constant linear velocity in contact with the wheel-type current terminals and the wheel-type voltage terminals.
