An adapter and apparatus for coupling a corded peripheral device with a portable terminal. The gate dielectrics may include lanthanum oxide, preferably amorphous lanthanum oxide andor an alloy of lanthanum oxide and silicon oxide, such as lanthanum silicate. The stator segment assemblies are positioned around an outer surface of an assembly fixture. The second metal layer includes a CuNi alloy, and is provided so that the first metal layer is sandwiched between the first ferromagnetic layer and the second metal layer. The second transverse dimension is within an ISO H7 standard tolerance. The plant is highly tolerant to heat and cold, and has high resistance to pests and diseases, particularly powdery mildew, and a high resistance to rain.
