Procédé de fabrication d'un condensateur au tantale et à électrolyte solide, du type sans fil ni ruban de sortie, selon lequel on prépare un corps poreux (2) de tantale prolongé sur une face (3) par une tige de tantale (6), on forme une couche diélectrique (7), on dépose une couche (9) d'électrolyte solide sur ce corps et sur une partie de la tige, et on dépose une couche (10) de contre-électrode sur une partie de cette couche d'électrolyte solide, on enrobe le corps poreux dans un manchon (11) en matière électriquement isolante en laissant à nu une portion de la contre-électrode et on dépose des couches conductrices terminales (12-13 : 14-15) isolées l'une de l'autre, respectivement en contact avec la tige (6) et la contre-électrode (10), caractérisé en ce que l'on forme par moulage ledit manchon (11) en masquant ladite portion de la couche de contre-électrode (10) en sorte d'en empêcher tout recouvrement. De préférence la tige est sectionnée au ras du manchon et établit par sa tranche (6A) un contact électrique avec la couche électrique terminale associée (12-13).

A joint section where covering films 2a, 2b of film-covered battery 1 are heat-sealed together is formed with flat surface 6' having thickness t 1 and groove 6 having thickness t 2 . Groove 6 serves to reduce the projection area of film-covered battery 1 by folding side 2c toward receiving section 2a1 with groove 6 serving as an edge, and groove 6 is made thinner than flat surface 6' by Δt=t 1 -t 2 . Therefore, the length of covering films 2a, 2b produced on outer side 6a is shortened as compared with the case of folding the portion that has thickness t 1 .

A production device 100 for a packaged electrode 20 includes a conveyance unit 200 which superimposes an electrode 40 and a pair of separators 30 from a front end 51 side of a conveying direction while conveying the electrode 40 and the pair of separators 30, first joining units 300 which join lateral edges 31 of the pair of separators to each other, and second joining units 400 that join at least either front edges 32 or rear edges 33 of the pair of separators to each other. The lateral edges of the pair of separators, which are superimposed while being conveyed by the conveyance unit, are joined to each other by the first joining units from the front end side of a conveying direction. Then, at least either the front edges or the rear edges of the pair of separators are joined to each other by the second joining units in a state where conveyance by the conveyance unit is stopped.

A resin-metal composite sealed container having a heat seal part using a heat-sealing resin, between an end part of a first metal foil and an end part of a second metal foil, and a metallically sealed part with a weld bead, on the end face outside the heat sealed part of the first metal foil and the second metal foil. The resin-metal composite sealed container, wherein the melting point of the metal constituting the metal foil is higher by 300°C or more than the thermal decomposition temperature of the heat-sealing resin, the specific gravity of the metal constituting the metal foil is 5 or more, and the weld bead is formed by a laser welding. A method for producing a metal-resin composite sealed container, comprising forming a container by heat sealing end parts of metal foils having laminated on at least one surface thereof a heat-sealing resin, and forming a metallically sealed part with a weld bead on the end faces of the metal foils by heating/welding an outer side of the heat sealed part of the container from a side of the end faces of the metal foils.

A device in encapsulating an electric capacitor member (6) in a thermosetting resin by means of mulding without using a vacuum. The device comprises an insulating lamina (1) intended for placing in a mould (7) before the capacitor member (6) is inserted into the mould. The lamina is preformed to suit the mould and is provided with protuberances (2, 4) on its surface to give a space between it and the inner surfaces of the mould. Furthermore, there are holes (3) made in the lamina surface facing towards the bottom surface of the mould, for allowing the flow of resin through the lamina from the volume enclosed therewith to the space between lamina and mould.
