Abstract: Provided is a portable device which make it possible to facilitate analysis, in cooperation with an external system, on data obtained by optical fiber sensing. A portable device comprises: a sensing unit configured to execute optical fiber sensing using an optical fiber cable; an analysis unit configured to execute primary analysis processing on sensing data obtained by the optical fiber sensing; a communication unit configured to transmit data containing the results of the primary analysis processing to an external analysis unit configured to execute, outside the portable device, secondary analysis processing based on the results of the primary analysis processing; and a housing which accommodates the sensing unit, the analysis unit, and the communication unit.

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.

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).
