A field-effect transistor including localized halo ion regions that can optimize HEIP characteristics and GIDL characteristics. The coolant can be introduced into a coolant introduction chamber and is then introduced into a first coolant contact chamber by injection from a central nozzle. The participants compete their hands against at least one other participant’s hands to determine who has the highest ranked hands. The pick-up cap is generally rectangular, and has clasps at two opposite ends thereof. The device includes a cylindrical body of given length and diameter, an eccentric weight rotating by a driving element within the cylindrical body, a handgrip coaxially extending to the cylindrical body, and a turbine mounted between the handgrip and the cylindrical body and forming the driving elements of the eccentric weight.
