Der vorliegenden Erfindung liogt nun die Irkenntnis zugrunde, daß as durch strukturelle Beeinflussung der Stoffe, aus denen die 'I'hei

O FigurenThe present invention is based on the ignorance that it is possible to increase the effective Taero force by structurally influencing the substances of which the elements are made. According to the invention, in the production of Jhemoelasenten, such an influencing of the substances forming the legs is provided that the thermal conductivity is reduced. Casting can mainly be done by influencing the packing density when manufacturing the thermocouples by pressing or fining from a granular powder. 3s can also be produced by pressing chips or webs, or the thermocouples are built up from foils or the like. 2s can aubh a corresponding structural change can be achieved by using Bchaumbildnern or similar methods ergibta an increase in the effective thermal power Da * erfindungsgeja & SSE Yerfahren is particularly advantageous effect in such materials or Stoffp aar en ,, have the already relatively high at Bich i ILerEokrafte such as the Antison-Wlsiaut couple.
