摘要： A method of manufacturing an electronic component includes manufacturing a ceramic element including one pair of end surfaces and four side surfaces, forming external electrodes at both end portions of the ceramic element, measuring an initial characteristic value, determining any side surface to be machined among the four side surfaces and then determining, based on stored data, an amount of machining to be performed on the side surface to be machined, and machining, by the determined machining amount, the side surface of the ceramic element, which is determined to be machined, to be flush or substantially flush with the external electrodes.

摘要： A cylindrical film-type resistor comprising a cylindrical ceramic substrate to which is adherently applied a film of resistive material. Laminated over or under such resistive film are a plurality of termination films of conductive material. The termination films extend longitudinally of the substrate, and are so shaped and connected that the heat generated in the resistive film causes the temperature of the resistor to be substantially uniform throughout the length of the substrate. Stated more specifically, the termination films are combs with intermeshing teeth, and each tooth is relatively narrow at the central region of the substrate and relatively wide at the end portions thereof. Preferably, each comb tooth is generally hourglass-shaped.

摘要： A process for the manufacturing of an electric resistance for a hybrid miniaturized circuit from a wafer of p-type silicon or germanium, consisting in preparing said wafer with dimensions exceeding those corresponding to the required resistance value; diamond cutting said wafer into smaller ones, preparing for each smaller wafer two connections in the form of gilded metal strips, welding each smaller wafer to its two connections at a temperature above the gold-semiconductor eutectic formation point, and adjusting said smaller wafers to said required resistance value by removing material therefrom by means of an abrasive powder stream.
