    摘要: An apparatus and a process for producing a laminate for electronic parts such as ceramic capacitors. After a predetermined pattern for forming an internal conductive layer is formed on a self-supporting green sheet which contains inorganic powder and an organic binder, the self-supporting green sheet is taken up by a columnar roll and laminated. At this point, the position of the same pattern on the green sheet G2 of the next cycle to be laminated adjacently onto the green sheet G1 of the previous cycle as the above pattern with respect to the predetermined pattern on the green sheet G1 taken up by the columnar roll is determined.

    摘要: A meta-type wholly aromatic polyamide containing, as principal repeating units, meta-phenylenediamineisophthalamide units is dissolved in an amide compound solvent; the resultant polymer solution is subjected to a wet-spinning procedure wherein the polymer solution is extruded in the form of filamentary streams into a coagulation bath containing an amide compound-containing solvent and water but substantially not containing salts, through spinning orifices of a spinneret, to coagulate the extruded filamentary polymer solution streams in the coagulation bath; the coagulated porous undrawn filaments are subjected to a drawing procedure wherein the porous undrawn filaments are drawn in a plasticizing drawing bath containing an aqueous solution of an amide compound solvent; the resultant drawn filaments are washed with water, and then heat-treated (for example, further drawn at a draw ratio of 0.7 to 4.0 while being heated at a temperature of 250 to 400° C.), to provide uniform and dense meta-type wholly aromatic polyamide fibers.
