  • Publication number: 20240170777
    Abstract: A power storage device includes a case member, a terminal member inserted in an insertion hole of the case member, and a resin member joined to the case member and the terminal member. The resin member includes, on a resin outer surface exposed on an outer side of the case member, at least any one of a recess and a projection portion increasing a creepage distance from a terminal outer surface, which is exposed on the outer side of the case member, of the terminal member to a case outer surface exposed on the outer side of the case member.

  • Publication number: 20240170776
    Abstract: A method for producing a power storage device includes an insert-molding step in which a resin member is formed by insert molding with a terminal member inserted in an insertion hole of a case member. This insert-molding step is performed using a molding mold that includes a top-surface contact portion which is to face and tightly contact with a terminal top surface of the terminal member, an inner annular flat portion and an outer annular flat portion to form a frame top surface of the resin member, and an annular protruding portion to form an annular groove of the resin member.

  • 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.

  • Publication number: 20240113367
    Abstract: A method for producing a power storage device includes placing a lid assembly that includes a lid and a terminal member integrated therewith via a resin member to close an opening portion of a case body with the lid, and laser-welding the opening portion of the case body and the peripheral portion of the lid over an entire circumference. In placing the lid assembly, a peripheral high-level region, in which a peripheral outer surface of the peripheral portion of the lid is located on the outer side relative to an opening end surface of the opening portion of the case body is provided in proximate long-side opening portions, close of the opening portion and proximate long-side peripheral portions of the peripheral portion.

  • Publication number: 20240113368
    Abstract: A method for producing a power storage device includes closing an opening portion of a case body with a lid of a lid assembly, and laser-welding the opening portion of the case body and a peripheral portion of the lid over their entire circumference. A resin member has an outer surface including a scattered light-reached surface to which scattered light of a laser beam directly reaches, at least a part of the scattered light-reached surface including a smoothed region having a surface roughness of 0.6 ?m or less.

  • Publication number: 20240113366
    Abstract: A method for producing a power storage device includes forming a lid, forming a lid assembly, closing, and welding. In forming a lid, there is included forming, by forging, a protruding portion between a peripheral portion and an insertion-hole surrounding portion of the lid to block scattered light of a laser beam from being irradiated to a resin member, with a distance D from an end surface of the peripheral portion to a side surface of the protruding portion falling within 0.5t (D?0.5t) relative to a thickness t of the lid.

  • Patent number: 5970897
    Abstract: A method for sewing panty hose with a backpanel-like gusset inserted includes steps of cutting inner thigh portion of left-and-right aligned cylindrical hose materials and thereafter inserting the backpanel-like gusset material to a position ranging from rear portion to inner thigh portion of the panty part. The backpanel-like gusset material is folded into two and inserted into between the upper middle clamp and the lower middle clamp of a pair of left and right clamp groups. After the cutting of the gusset material, upper edge portion and lower edge portion of the gusset material inserted between the upper and lower middle clamps are sewn individually to cut edges of the hose materials.

  • Patent number: 5564609
    Abstract: A method for mounting pantyhose blanks which enables a pair of pantyhose blanks to be efficiently and accurately mounted on a stretch holder member of a crotch sewing machine employed in pantyhose sewing. Panty portions of a pair of pantyhose blanks are inserted on a pair of upper and lower insertion plates at a first position. At a second position, the panty portions are shifted widthwise on the respective insertion plates so that a cutting site at which the panty portions are to be cut is positioned in alignment with a center line extending across the insertion plate pair. At a third position, the panty portions are drawn so that run guard portions are set in position on the respective insertion plates; the panty portions are stretched in opposite lateral directions by a pair of pawls which act as a transfer member and are held as such before they are withdrawn from the insertion plate pair, the panty portions being then mounted on the stretch holder member of the crotch sewing machine.
