Abstract: The objects of the present invention are to provide a magnetic field molding device capable of improving yield in a production and stabilizing product quality, and a method for producing a ferrite magnet. In molding in a magnetic field, the mortar-shaped die 19 provided with a plurality of the cavities 13 is heated by the heater member 20, provided in the heater block located under the mortar-shape die 19, under control of a controller at varying temperature depending on the position of the mortar-shape die 19, to keep uniform temperature of the slurry in the cavities 13. This assures good and stable slurry dehydration properties and improves product yield.

Abstract: A process for production of a magnet which comprises step of supplying a slurry S containing magnetic powder and a dispersing medium into the cavity C of a molding apparatus 12, a step of compression molding the slurry S while applying a magnetic field to the slurry S to obtain a molded article and a step of sintering the molded article to obtain a magnet, wherein the molding apparatus 12 comprises a die 121 having a through-hole 121a into which the slurry S is supplied, a slurry supply gate 121d being formed in the inner wall surface 121b, a die 122 inserted in the through-hole 121a and a die 123 that forms a cavity C together with the dies 123, 122, the slurry S being supplied in an amount such that it is less than the volume of the cavity C when the die 122 has been inserted in the through-hole 121a and has blocked the slurry supply gate 121d, and in the step of obtaining the molded article, the slurry S is compression molded after the die 122 has blocked the slurry supply gate 121d.

Abstract: The objects of the present invention are to provide a magnetic field molding device, and method for producing a ferrite magnet, or the like, capable of improving yield in a production line and stabilizing product quality, and method for producing a ferrite magnet. In molding in a magnetic field, the mortar-shaped die 19 provided with a plurality of the cavities 13 is heated by the heater member 20 at a given temperature level, under the control of the controller 23. The temperature level is preferably controlled by the controller 23 at 40° C. or higher as mortar-shaped die 19 temperature T1, sensed by the sensor 22. A molding slurry can be kept at a high temperature level in the cavities 13 by heating the mortar-shaped die 19, and can have high dehydration properties and improve product yield.

Abstract: In an electric double layer capacitor 100 comprising an electrochemical element 30 including a pair of electrode layers 32, 36; a pair of container members 10, 20 made of a metal surrounding the electrochemical element 30; and an electrically insulative gasket 40, interposed between the pair of container members 10, 20, for electrically insulating the container members 10, 20 from each other; the electrochemical element 30 is sealed by causing a crimping part 10bof one container member 10 to crimp a brim 20b of the other container member 20 while interposing the gasket 40 between the crimping part 10b of one container member 10 and the brim 20b of the other container member 20, whereas the crimping part 10b of one container member 10 and the brim 20b of the other container member 20 are bonded to each other by the gasket 40.
