  • Hyperthermia device
    Patent number: 5232433
    Abstract: A hyperthermia device includes a pair of magnetic poles for applying an alternating magnetic field in a body to be heated, these two magnetic poles being laterally arranged on the surface of the body and having time varying polarities opposite to each other, and allowing a line of magnetic force including a component perpendicular to the surface of the body in the vicinity of these magnetic poles.

  • Diamond n-type semiconductor diamond p-n junction diode
    Patent number: 5223721
    Abstract: A diamond n-type semiconductor including a substrate and a phosphorus element-doped diamond thin film disposed on the substrate. The diamond thin film is deposited by vaporizing a solution comprising a liquid organic compound as the diamond material with diphosphorus pentoxide (P.sub.2 O.sub.5) dissolved therein, and subjecting the resultant gas to a hot filament CVD method.
