A communications system is provided which can search for information about a communications device that is not registered in a network by designating time. The search system, which includes a plurality of communications devices, gateways and an entity management server, can execute a search method. The entity management server stores in a storage device the identification information of the communications device sent from the gateways with establishing correspondence with notification time. The entity management server receives from a mobile terminal the identification information of the communications device and designated time. The entity management server searches for the identification information stored in the storage device at the designated time, and identifies the location information of the gateways corresponding to the identification information included in the search request.

Around a damaged area of a jacket of a flexible tube, a top coat layer whose adhesion to a polymer layer is weak is peeled off with an adhesive tape. The damaged area and its immediate surrounding area are sanded, and then wiped with ethanol for cleaning. A main agent and a hardening agent are heated and defoamed while being mixed to prepare a repair material. The repair material is applied to the damaged area and the immediate surrounding area. A heat shrink tube is opened along slits in an end portion and covers the flexible tube. The heat shrink tube is shrunk with hot air, pressing the repair material and making it flush with a surface of the jacket. The flexible tube is heated with an electric hot plate to harden the repair material. Thereafter, the heat shrink tube is peeled off from the flexible tube.
