    摘要: Polymeric composites may be produced by a process comprising melt-kneading an organophilic clay and a polymer at an average reduced pressure of at 5×104 Pa, a maximum reduced pressure of at least 1×105 Pa, and a total shear strain between 105 and 107, and/or a total shear energy per unit volume falling between 1010 and 1014 Pa. Polymeric composites produced under these conditions may have 50% or more of the entire layers of the layered organophilic clay dispersed as monolayers.

    摘要: A polylactic acid composition containing polylactic acid and ester-based plasticizer, wherein a content of the ester-based plasticizer is 16 to 33 wt %, and when the composition is highly deformed by stress loading as the relation between the stress and the deformation deviates from linear viscoelastic behavior and thereafter the stress is released, residual deformation measured after the stress is released is not less than 66.0% after 0.2 minute of the stress release, and is not more than 34.0% after 240 hours of the stress release.

    摘要: A resin seal apparatus includes a movable bottom die vertically moved by an elevator mechanism, a transport mechanism horizontally moving the movable bottom die having placed thereon a printed circuit board with a semiconductor chip mounted thereon, an intermediate die abutting against a periphery of the printed circuit board when the movable bottom die is moved upward, a film of resin stretched by a film stretch mechanism over the intermediate die and the printed circuit board, a die for a chip, pressing a back surface of the semiconductor chip via the film of resin, and a top die pressing a top surface of the intermediate die via the film of resin. This apparatus allows a PCB with a semiconductor chip mounted thereon in the form of a flip chip to be sealed with resin in a reduced period of time to fabricate an electronic component.
