摘要： A process for producing a PTC device comprising the steps of forming a laminate comprising a PTC composition and at least two electrode plates having the PTC composition sandwiched therebetween, opposing the surface of a lead plate to be electrically connected to each of the electrodes, to the surface of each of the electrode plates of the laminate while contacting at a narrow area, and then passing a current between the electrode and the lead via the narrow contact surface to weld them. By this process, there is obtained a PTC device having, at a portion of the joining interface between each electrode plate and each lead plate, a nugget formed by melting both the plates. This PTC device has a low contact resistance between the PTC composition and the electrode plates.

A respective plurality of branch-shaped electrodes is connected to each of the first and second power supplying portions. The plurality of branch-shaped electrodes connected to each of the power supplying portions is arranged so as to extend toward the side of the other power supplying portion. The branch-shaped electrodes connected to each of the power supplying portions are arranged so as to be interdigitated with the branch-shaped electrodes connected to the other power supplying portion. The organic positive temperature coefficient thermistor is characterized in that at least one of the first and second power supplying portions is constituted by a plurality of power supplying electrodes which are insulated from each other. A plurality of branch-shaped electrodes is connected to each of the plurality of power supplying electrodes, and they are distributed along the power supplying electrodes with a predetermined spacing and with a predetermined ratio between the respective members of branch-shaped electrodes on each of the power supplying electrodes.

摘要： A self-regulating heating article includes a first elongate layer formed by a crystalline polymeric composition of high crystallinity and conductive particles dispersed in the polymeric composition to exhibit a positive temperature coefficient of resistance. A pair of elongate electrodes, which are adapted for connection to a power supply, are secured one on each surface of the first layer to develop a potential in the direction of thickness of the first layer. The electrodes are arranged so that a creeping distance which is greater than the thickness of the first layer is established between the electrodes along peripheral edges thereof. The creeping distance prevents insulation breakdown and ensures safe, high wattage operation at power supply voltages.

摘要： A positive ceramic semiconductor device having positive temperature coefficient of resistance comprises a pair of electrodes provided on a ceramic semiconductor substrate. One of the paired electrodes which is to serve as the positive pole is basically constituted by at least an electrically conductive layer of silver-palladium series containing silver and palladium at a predetermined ratio. For preventing a localized current concentration from occurring in the current conducting state, improvement is made as the structure of the positive pole electrode ormed of the electrically conductive material of silver-palladium series and/or the structure of the negative pole electrode. Silver-migration phenomenon on the positive ceramic semiconductor substrate as well as degradation of the mechanical strength thereof is positively prevented.

摘要： A self-regulating heating article comprises a first elongate layer formed by a crystalline polymeric composition of high crystallinity and conductive particles dispersed in the polymeric composition to exhibit a positive temperature coefficient of resistance. A pair of elongate electrodes, which are adapted for connection to a mains supply, are secured one on each surface of the first layer to develop a potential in the direction of thickness of the first layer. The electrodes are arranged so that a creeping distance which is greater than the thickness of the first layer is established between the electrodes along peripheral edges thereof. The creeping distance prevents insulation breakdown and ensures safe, high wattage operation at mains voltages.

摘要： An electrical component, particularly a varistor, having high strength given stressing due to temperature change and due to surge currents is composed of a ceramic body whose end faces contain solderable metallic coatings as electrodes to which power supply elements are soldered, the latter being composed of a closed strip which leaves open and inwardly-disposed area and an outwardly-disposed area on the coating and which is dimensioned such that the condition Fa:FI=Ua:Ui=1.05 through 1.35 is met, where Fa is the surface of the coating located outside of the power supply element, Fi is the surface of the coating lying inside the power supply element, Ua is the outer circumference of the power supply element and Ui is the inner circumference of the power supply element. Each power supply element contains a lead clip which is spaced from the metallic surface by bends to such a degree that the clip is not soldered to the metallic coating.

摘要： Electrical devices which comprise at least one metal electrode and a conductive polymer element in contact therewith, wherein the metal surface which contacts the conductive polymer has a roughened or otherwise treated surface to improve its adhesion to the conductive polymer. The metal electrode is preferably an electrodeposited foil. The conductive polymer preferably exhibits PTC behavior. The devices include heaters and circuit protection devices. The improved adhesion results in improved physical and electrical stability, and broadens the range of conductive polymer compositions which can be used in a number of important applications.

摘要： A component consisting of two coupled PTC thermistors with the first thermistor having a lower cold resistance than the second thermistor and the first thermistor having a higher resistance at the operating temperature than the second thermistor. According to the invention, the electric connection to the second thermistor is made directly by solely mechanical contacts to the surface of the ceramic thermistor body. This means a considerable simplification during manufacture, as the second thermistor need not be provided with electrode layers.
