  • this object can be achieved by a
  • thick film heating element having a multi-layered construction with different
  • intermediate layer would only have to withstand 250N, perhaps with a high
  • the intermediate insulating layer can be
  • the reduced thickness of the intermediate layer will also be acceptance.
  • the reduced thickness of the intermediate layer will also be acceptance.
  • the various firing operations may be combined by firing multiple layers at
  • the additional track(s) may include other features, such as an
  • Patent Application No. for example, and tappings from either track
  • underlying track could be made through holes in the intermediate insulating layer, and access to the tracks for bimetal or other sensors can also be similarly provided.
