Abstract: The present invention relates to a storage battery recycling method including: a step of disassembling into each constituent component based on a disassembly method in accordance with a type of storage battery; a step of cutting an electrode component among the constituent components to generate cut pieces; a step of arranging the cut pieces on a mounting member provided in a container containing water; a step of separating the cut pieces into a plurality of elements made of different materials by performing electric pulse discharge in water in the container; and a step of sorting and recovering by type the plurality of elements made of different materials and separated from the cut pieces.

Abstract: A storage battery recycling device includes a container which can store water, a sieve-like placement member provided in the container, and a discharge part configured to perform electric pulse discharge in water in the container in which water is stored, wherein the discharge part is configured to perform the electric pulse discharge a predetermined number of times on an electrode component of a storage battery placed on an upper surface of the placement member, and to separate the electrode component into a plurality of elements made of different materials.

Abstract: A spiral separation membrane element (1A) includes: a wound body (3) including a separation membrane; a core tube (2) that penetrates the wound body (3) along the central axis of the wound body (3); and a joining portion (4) that joins the wound body (3) to the core tube (2) at at least one end face (3a) of the wound body (3). The joining portion (4) has a holding portion (41) disposed inwardly of the end face (3a) of the wound body (3) and an extending portion (42) formed integrally with the holding portion (41). The spiral separation membrane element (1A) further includes a restraining member (5A) that secures the extending portion (42) to the core tube (2).

Abstract: A separation membrane module (1A) includes: a tubular pressure container (7); a plurality of separation membrane elements (2) inserted in the pressure container (7) and each having a first end member (3) and a second end member (4); and a sealing member (5A) mounted on one of or both the first end member (3) and the second end member (4) that are adjacent to each other. In a normal condition, the sealing member (5A) is located radially inward of a maximum diameter portion of the first end member (3) and/or the second end member (4) on which the sealing member (5A) is mounted. The sealing member (5A) is deformed due to contact between the adjacent separation membrane elements (2) or due to supply of a pressurized liquid into the pressure container (7), and comes into close contact with an inner circumferential face (7a) of the pressure container (7).

Abstract: Provided is a communication terminal capable of suppressing the phenomenon of personal information being transmitted contrary to the will of the person.
