Abstract: The invention relates to an integrated resistor formed in an epitaxial layer and provided with at least one tap. In order to reduce field effect action between the resistor and the epitaxial layer, the voltage on the two ends of the epitaxial layer underneath the resistor tracks the voltage on the two ends of the resistor. Moreover, the epitaxial layer is short-circuited by means of buried layers at the locations where the resistance layer also exhibits a short-circuit, such as underneath the contact area of the tap.

Abstract: A cable which is capable of being made in a large pair size and yet which has excellent mechanical properties that maintain its integrity notwithstanding extremes in temperature during installation and shipping as well as during the rigors of installation includes a sheath system having a corrugated steel outer shield that is adhesively bonded to a plastic jacket. The corrugated steel shield which is formed to have a longitudinal overlapped seam that is preferably unsealed encloses an aluminum inner shield that in turn encloses a multiconductor core. Advantageously, the sheath system includes a plastic jacketing material which is capable of resisting biaxial stresses which are aggravated in a bonded sheath system. This results in jacket integrity about the longitudinal seam of the outer shield notwithstanding a notched cross-section and an unsupported bridged portion of the plastic jacket adjacent to the seam.

Abstract: A temperature limiter used as part of, or otherwise in combination with, an electric cooking plate. An improved switching hysteresis is enabled by a unique construction in which a laterally open recess is formed in a one-piece housing to receive a snap switch, the counter-contact of which is fixidly secured in slot structure adjacent said recess. A transmission rod is arranged within an expansion sleeve and is positioned to be spring biased through engagement with the spring of a snap switch.
