Abstract
Abstract A film thermoelement wherein each branch thereof comprises a film of a semiconductor material contacting on one of its sides a hot thermal bus and on the other of its sides a cold thermal bus. The contact between the thermal buses and the film is maintained through separate strips of a heat-conducting material displaced with respect to each other on the opposite sides of the film. The gaps between the contact strips may be filled with an inert gas.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
94 words
A film thermoelement comprising: branches; a film of a semiconductor material in each said branch; a plurality of contact strips applied onto one side of said film and forming gaps therebetween; another plurality of contact strips applied onto the other side of said film and forming gaps therebetween said another plurality of contact strips being displaced with respect to said first plurality of contact strips; a hot thermal bus in direct contact with said first plurality of contact strips; and a cold thermal bus in direct contact with said other plurality of contact strips.
Claim 2
Dependent Claim
