Abstract: An automotive instrument panel pad covering the instrument panel except for an opening formed therein, the pad being provided with a stepped portion which extends along the entire inner periphery of the pad and is interposed, adjacent to the margin of the opening, between the instrument panel and an outfit such as, for example, cluster lid mounted in such a manner as to cover the opening. With this construction, it is possible to avoid the occurrence of noise which would otherwise result from interference between the instrument panel and the cluter lid. It is also possible to realize an improved outward appearance.

Abstract: A pneumatic converter comprising a bellows having in its interior a coupling plate connecting the two ends of the bellows together at a position offset from the center axis of the bellows.

Abstract: An improved differential pressure transducer includes a chamber divided by a non-magnetic, electrically conductive measuring diaphragm supported between two support members each of which has a cavity covered with a seal diaphragm. Differential pressure of an incompressible fluid medium to be measured and transduced is applied to the measuring diaphragm, the displacement of which is detected by magnetic core detection coils. The detection coil magnetic cores are joined to the support members through spaces of magnetic material having temperature dependent characteristics opposite to that of the cores to thus neutralize temperatures induced effects.
