Abstract: An electrical component has a terminal construction allowing it to be electrically and mechanically connected to an electrode. A terminal made of a metal material is mounted on an insulating substrate which has front and rear surfaces and is mounted on the front surface thereof with an electrode. The terminal includes a clamp section for clamping the substrate through front and rear surfaces thereof. The clamp section includes a first contact element contacted with the electrode and a second contact element contacted with the rear surface of the substrate. The first contact element is adhesively bonded to the electrode. Electrical connection between the first contact element and the electrode is carried out by direct contact therebetween. The second contact element of the clamp section is adhesively bonded to the rear surface of the substrate.

Abstract: A furnace to be heated to a high temperature which employs heating elements made from carbon or graphite. A longitudinal space within the furnace for accommodating said heating elements and a furnace bed for the transportation of articles to be treated through the furnace, is formed solely by blocks of porous carbon and without the emplyment of a conventionally prerequisite protective case. A pair of the heating elements extend along inner lateral walls of said space, facing to each other with the furnace bed therebetween, and have their electric terminals projecting through and outside of a bottom wall of the furnace.
