  • Publication number: 20240178495
    Abstract: A power storage device includes a case having a metal lid with an insertion hole, a terminal member inserted through the insertion hole, and a resin member insulating between the case and the terminal member. The lid has a surface facing outside, including a ring-shaped hole-surrounding region around the insertion hole, to which the resin member is airtightly firmly fixed, and an outer region contacting the resin member. A two-region consisting of two, the hole-surrounding region and the outer region, has a two-region length at a two-region length ratio of 3.0 or more, which is the ratio of the maximum two-region length to the minimum two-region length, and a seal length of 1.4 or less, which is the ratio of the maximum seal length to the minimum seal length of the hole-surrounding region.

  • Publication number: 20240170816
    Abstract: A method for producing a power storage device includes a process of insert-molding. This process is to relatively move a first mold and a second mold to press a terminal top surface of a terminal member by a top-face close-contact portion of the first mold to a second-mold side and to press a to-be-contacted portion of the terminal member by a contact portion of the second mold to a first-mold side so that a deformed portion of the terminal member is elastically deformed. A resin member is thus insert-molded while the terminal top surface is pressed and tightly contacted with the top-face contact portion.

  • Publication number: 20240170814
    Abstract: A method for producing a power storage device includes an insert-molding step of making a resin member by insert-molding with respect to a terminal member inserted in an insertion hole of a lid. In this insert-molding step, the insertion hole of the lid is placed in front of a gate, and a molten resin is injected through the gate to flow in an opposite gate-side space in a cavity through the insertion hole, allowing the molten resin to spread over the entire cavity, to form the resin member.

  • Patent number: 10779132
    Abstract: A processor (103) in a wireless terminal (10) executes a communication service application to thereby perform an operation as a client for using a communication service. Further, in an abnormal situation where the wireless terminal (10) cannot access a server system (50) of an operator of the communication service, the processor (103) executes a predetermined activation procedure in the wireless terminal (10) without passing through the server system (50) to thereby activate a special account in the wireless terminal (10). This makes it possible, for example, to perform communication by the special account using an online service application installed in the wireless terminal during an abnormal situation where the wireless terminal cannot access the online service server.
