Abstract: This invention relates to a composite function element characterized by forming a high resistance thin film layer containing the constitutional elements of perovskite type oxide and speicfied impurity elements at the grain boundary of a sintered product which is an agglomerate of n type semiconductor particles, and to a process for producing said composite function element. Said composite function element has such a composite function that it acts as a varistor passing high voltages at a high voltage and as a capcitor passing the currents of abnormal frequency zone at a low voltage, so that the functions of the two elements, a varistor and a capacitor, can be fulfilled simultaneously with only one element. Therefore, its extensive application to the usage of, for example, prevention of erroneous work in microcomputer-controlled instruments can be expected.

Abstract: The invention relates to a pneumatically operating drawing cushion for presses, in particular for mechanical presses for sheet-metal forming. The invention is intended to provide greater economy on the basis of better use of the energy supplied, and to provide savings in material and technical outlay by virtue of smaller cushion dimensions, and also the elimination of cooling devices for the oil circulation. For this purpose, the proportion of the energy stored in the cushion when the ram is at its low point, and which is not required for the ejection process, is used to build up a high operating pressure in the cushion and to generate compressed air for other consumers. According to the invention, this happens when the cushion plunger (3) is embodied as a differential plunger pressurised on two sides by compressed air, and the upper part (14) of the cylinder space (2) is provided with a non-return valve (15) and is connected via piping (16), which is provided with a further non-return valve (17) and/or a controllable distributing valve (18), to the lower part (12) of the same, and when the lower part (12) of the cylinder space (2) is connected to a compressed air vessel (21) via a pressure-limiting valve (20) (Fig. 1). <IMAGE>

Abstract: Es wird ein in Druckschaltungstechnik ausgebildeter Dickschichtkondensator sowie eine derartige Kondensatoren und zugehörige Leiterbahnen enthaltende gedruckte Schaltung beschrieben. Das Kondensator-Dielektrikum besteht aus einer siebdruckfähigen Dispersion von dielektrischen Füllstoffen in einem bei relativ niedrigen Temperaturen aushärtbaren Polymermaterial, insbesondere einem Polymerharz aus der Gruppe Polyurethan-, Polyester, Epoxy-, Melaminformaldehydharz. Die Verwendung eines derartigen Dielektrikums ermöglicht die Anwendung niedriger Einbrenntemperaturen im Bereich um ca. 200°C, im Gegensatz zu bekannten Dickschicht-Kondensatorausrührungen mit einem Glas- bzw. Keramikfritte enthaltenden Dielektrikum, für welche Einbrenntemperaturen in der Größenordnung von 1000°C erforderlich sind. Die Herstellung der unteren und oberen Kondensatorelektroden erfolgt vorzugsweise in einem einheitlichen Verfahren mit der Herstellung der zugehörigen Leiterbahnen der gedruckten Schaltung. Vorzugsweise werden die Kondensatorelektroden und jeweils zugehörigen Leiterbahnen durch stromlose Abscheidung aus dem chemischen Bad auf einer für derartige stromlose Abscheidung aktivierten Grundlageschicht erhalten. Auf diese Weise werden voll lötfähige Kupfer- oder Nickelektroden und -leiterbahnen hoher Haftfestigkeit an den Unterlageschichten erhalten. Es wird ferner die Ausbildung einer derartigen gedruckten Schaltung mit in einer Matrix angeordneten Kondensatoren und zugehörigen Anschlußleitungen als kapazitive Eingabetastatur für Datenverarbeitungsanlagen beschrieben.

Abstract: A multi-mode radio receiver divides the radio frequency input into two channels and in each channel mixes it with the carrier wave frequency. A quadrature shift in the mixing carrier wave frequencies enables base band signals to be filtered from the mixer outputs. The analogue quadrature signals are converted to digital form and processed digitally to reproduce the original modulating signal for am, fm or pm transmissions. For ssb modulation the mixing frequency is the side band centre frequency instead of carrier frequency.
