  • Patent number: 9842703
    Abstract: An aluminum electrolytic capacitor includes a capacitor element having lead terminals; an armor case housing the capacitor element; and a rubber seal having a terminal passage hole for the lead terminals drilled therein and mounted on an opening section of the armor case. A hole diameter of a lead wire passage hole is smaller than an outside diameter of an outside lead wire, and a conical guide surface of progressively smaller diameter is formed between a round bar mating hole and the lead wire passage hole within a terminal passage hole. A passage guide part of progressively smaller diameter from a lead wire body is integrally furnished at an end of the outside lead wire so as to have a smaller diameter than the hole diameter of the lead wire passage hole, forming a conical sloped surface having a predetermined angle on a peripheral surface of the passage guide part.

  • Publication number: 20150016025
    Abstract: A lead terminal is passed through a terminal passage hole of a rubber seal, without imposing an excessive burden such that the characteristics of the capacitor element would be degraded, and while maintaining a state of reliable isolation from the outside air. In an aluminum electrolytic capacitor in which the hole diameter f2 of a lead wire passage hole (52) is smaller than the outside diameter f1 of an outside lead wire (22), the outside lead wire (22) being forcibly passed to the outside through lead wire passage hole (52), a conical guide surface (53) of progressively smaller diameter is formed between a round bar mating hole (51) and the lead wire passage hole (52) within a terminal passage hole (5).

  • Patent number: 6560631
    Abstract: A distributed data processing system uniformly managing distributed data and program files. A resource management database associates identifiers of resource files to be used in analytical processes with their respective storage locations. The identifiers should be unique in the distributed environment, so that all resource files will be uniquely distinguished from each other by using their identifiers. When requesting execution of a particular analytical process, the identifiers specify resource files necessary for the process. A process execution unit in the system first creates a work area, which can also be used to store intermediate data files created during the execution. The resource management database is consulted to know the locations of necessary resource files, and creates links in the work area to reach those files. The process execution unit executes the requested analytical process while making access to the resource files via the links in the work area.
