Abstract: An information processing method calculates a position of a feature corresponding to a trace in a first coordinate system, calculates a position of the feature corresponding to the trace in a second coordinate system, and calculates a size of a first distribution of the position of the feature corresponding to the trace in the first coordinate system and a size of a second distribution of the position of the feature corresponding to the trace in the second coordinate system. Additionally, the information processing method outputs information indicating that the feature corresponding to the trace is the trace formed on the surface of the workpiece in the machining process, and outputs information indicating that the feature corresponding to the trace is a false detection of the trace in the inspection process.

Abstract: An electronic component (for example, an electrolytic capacitor) includes an internal element (for example, a capacitor element) and a packaging (for example, a case). The production lot for the internal element includes a plurality of subunits. The packaging is provided with an identifier for identifying the plurality of subunits. By this configuration, it is possible to provide an electronic component capable of specifying production information, a production method for the electronic component, a management method for the electronic component, and a program. The identifier may be provided on the packaging as a display. Further, the identifier may be a one-dimensional code or a two-dimensional code.

Abstract: A method of manufacturing a positive electrode foil of an aluminum electrolytic capacitor is provided in which anodizing conditions are optimally determined and automatically set to minimize the loss of production and to produce a constant quality of the positive electrode foil. The method comprises an etching process and an anodizing process. An etched foil produced in the etching process is subjected to a constant current inspection, and then, the anodizing conditions are determined from the result of the constant current inspection. The anodizing conditions are transferred to a control panel in the anodizing process where they are automatically registered as its settings. Also, an apparatus for manufacturing the positive electrode foil is provided which has a voltage sensor connected between an output running roller and cathode electrodes in an anodizing tank. A voltage measured by the voltage sensor is fed back to a direct-current source for controlling its output voltage.
