Abstract: A press molding die structure having a paired press lower die and press upper die that are relatively movable to each other in which a work transferred into a portion between the press lower die and the press upper die is press-molded thereby to form a molded work. A concave portion is formed to a molding surface of the press lower die, and a suction cup of a vacuum stabilizer is provided to the concave portion formed to the molding surface of the press lower die, wherein the suction cup elastically sucks and retains the work at least at a time when the press molding dies are opened, thereby stabilizing a posture of the work.

Abstract: There is provided a dispersion method of stirring a material to be dispersed in a cavity of a container, so as to create a laminar flow of the material by the stirring action, and a dispersing apparatus including a bottom member and a column-shaped rotating shaft that rotates in the cavity of the container, in which the rotating shaft is provided with two vanes attached thereto with a predetermined inclination, at positions circumferentially spaced by 180 degrees, and the vanes are located at non-overlapping positions in an axial direction.

Abstract: The disclosed is a method for manufacturing polymer composite in which a polymer as a dispersion medium and an additive to be added to the polymer is stirred for mixing in a cavity of a vessel to prepare a polymer composite in which the additive is dispersed in the polymer with a prescribed condition, wherein the stirring for mixing is performed under temperature conditions of not more than the softening temperature of the polymer until the additive is dispersed in the polymer with a prescribed condition, thereby the polymer is forced to lower the molecular weight thereof ephemerally by subjecting at least a part of chemical bonds in the polymer to cleavage, and thereafter the cleaved parts are rejoined.
