摘要： A circuit protection device designed to protect a pair of electrical circuits by fracturing at such time as an overcurrent condition has occurred in a first of the circuits, this novel device comprising a substantially flat substrate of non-conductive, frangible material upon which a resistive component and a fuse conductor reside in an adjacent relationship on a common surface. The resistive component is part of a first circuit, and the fuse conductor is part of a second circuit. The resistive component, at the time of an overcurrent therethrough, becomes hot and causes a heating of the near surface of the frangible substrate. The frangible substrate, as a result of the uneven heating of its opposite surface, elongating and then fracturing, the fracturing of the frangible substrate thereby bringing about a fracturing of the resistive component as well as a fracturing of the fuse conductor, thus to effect an interruption of the first circuit as well as a substantially simultaneous interruption of the second circuit. This novel device is admirably suited for protecting a subscriber line interface circuit.

摘要： This film resistor is formed of an alloy whose principal components are nickel and phosphorus. On the surface of an electrically insulating base made of ceramic or the like, a conductor is provided by etching, activating, and electroless plating in that order. Then an alloy film whose principal components are nickel and phosphorus is formed not by electroless plating, but by electroplating. By adapting electroplating, it is possible to make the alloy film thinner in the central part of the surface of the insulating base than the parts of the edges. If an overcurrent is applied, fusing starts preferably at this thin part.

摘要： Es werden eine elektrische Dickschichtsicherung 10 sowie ein Verfahren zur Herstellung einer solchen Sicherung beschrieben. Hierbei wird auf ein Substrat 12 zur Herstellung einer Widerstandsschicht 24 eine leitfähige Paste aufgedruckt. Zweckmäßigerweise wird auf dieses Substrat jedoch zunächst nach Art eines Podestes eine dielektrische Schicht 22 aufgebracht, auf die anschließend überlappend die Widerstandsschicht 24 aufgebracht wird. Auf diese Widerstandsschicht 24 werden zwei einen Abstand d voneinander aufweisende Elektroden 14, 16 aufgebracht, zwischen denen ein einen Dickschichtschmelzleiter bildender Steg der Widerstandsschicht 24 belassen ist. Die Stegbreite wird durch Lasern eingestellt.
