    摘要: A semiconductor pressure transducer includes a monocrystalline semiconductor diaphragm, the outer edges of which are fixed. When subjected to pressure, the transducer produces radial strains of opposite polarity in a central portion thereof and a portion surrounding the central portion close to the edge of the strain inducing region. The diaphragm contains a plurality of elongated resistances formed of semiconductor material of the same conductivity type which are electrically isolated from the diaphragm, per se. Resistances of an individual set which lie in proximity to one another are combined in the form of a bridge. The longitudinal direction of resistances forming one set of opposing arms of the bridge extend along axes of the same crystal system as the longitudinal direction of the elongated resistances forming the other set of opposing arms of the bridge. However, the longitudinal directions of the separate sets of resistances forming the opposing arms of the bridge lie in directions so that they do not orthogonally intersect each other.

    摘要: In order to bring a moduled power converter into less size and cost in the case of a structure having a lead-insert-case, an insulated metal circuit board and a printed circuit board, a difficulty was encountered in thinning a wiring width and an increase in pad area for each metal wire has interfered with a reduction in its size and cost.In the present invention to cope with it, a power converter is constructed by using a semiconductor module having such a structure that a metal base and lead frames are adhered to each other in a state in which an insulating adhesive sheet is interposed therebetween, a resin-molded outer package is adhered to the metal base with an adhesive or the like, and a resin sealing agent is charged into the resin-molded outer package to thereby integrally seal the resin-molded outer package and circuit parts such as semiconductor elements implemented therein, whereby a reduction in size and cost thereof is realized.
