摘要:
This invention relates to an improvement on a sealed lead storage battery which comprises a case, positive and negative plates alternately disposed in a case, porous separators between the adjacent plates and electrolyte filled in the case so as to be retained at least in the porous separators.The sealed lead storage battery of the invention further comprises additional electrolyte porous retainer means disposed in an unoccupied space in the case so as to have increased amount of electrolyte. The additional electrolyte retainer means may be disposed in at least one of an upper space over the plate group, a lower space below the plate group and side spaces beside the plate group. The additional electrolyte retainer means may be of glass fine fiber mat, glass and synthetic fine fiber mat or gel. It may be integrally formed with the porous separators. Preferably, the positive and negative plates may be so porous that the electrolyte is retained in them.

A laminated rotor core (36) wherein permanent magnets (47) are inserted in respective magnet insertion holes (46) is disposed between and pressed by an upper die (37) and a lower die (29). The upper die (37) has resin reservoir pots (50) provided above the laminated rotor core (36) and at positions corresponding to the respective magnet insertion holes (46). Raw resin material put in the resin reservoir pots (50) is heated by the upper die (37). Subsequently, the resin material in a liquefied state is ejected from the resin reservoir pots (50) by plungers (52) that are inserted and moves vertically in the resin reservoir pots (50) and is directly filled in the magnet insertion holes (46). Consequently, the respective magnet insertion holes (46) are filled with the resin material more evenly and highly reliable products can be supplied at low cost.

A method of manufacturing a laminated core, having a laminated core body 10a formed by laminating plural core sheets 11 and having magnet insertion holes 13, 14 with openings 17, 18 opening to a inner space 15 or an external side, inserting and resin-sealing permanent magnets 20, 21 in the magnet insertion holes 13, 14, with the openings 17, 18 blocked by a blocking member 23, the method including: temporarily connecting blocking member pieces 32 to be the blocking member 23 in each of the core sheets 11 and removing the blocking member 23 with the laminated core body 10a resin-sealed. By this, without a special blocking member, the permanent magnets 20, 21 are resin-sealed while the magnet insertion holes 13, 14, parts of which have the openings 17, 18, are blocked.

摘要:
A punch apparatus for punching and laminating simultaneously a plural number of thin sheets is disclosed. This punch apparatus includes a punch provided on an upper portion of the punch apparatus, a die provided on a lower portion of the punch apparatus and used for punching a material to be processed, a stripper for guiding the punch during punching operation, a device for laminating punched materials using the punch as a laminating axis, a device for adjusting a relative position between the punch and the stripper when the upper and the lower portions of the punch apparatus are separated, and a device for adjusting a clearance between the die and the stripper during punching operation. The punch apparatus can open precisely almost straight very fine through-holes of a diameter of 100 μm or less even in a sheet of thin, soft and deformable material.
