    Abstract: PURPOSE: To provide a method for eliminating heavy metal ions from an aqueous solution by selectively separating the heavy metal ions in a short time for recovery without requiring addition of an assistant to the aqueous solution, and on the other hand a method for enriching the heavy metal ions from an aqueous solution by selectively separating the heavy metal ions in a short time for recovering the heavy metal ions for use for an absorbent, wherein the heavy metal ions are easily available, simply handled and produced at a low cost. CONSTITUTION: A copolymer composed of ethylene, (meth)acrylic acid and a (meth)acrylate is used for eliminating or enriching heavy metal ions from an aqueous solution. In this case, carboxyl groups of the copolymer may be neutralized by metal ions up to 100%.

    Abstract: PURPOSE: To make mass production and to perform a forming processing of melted materials which harden gradually, by pushing out polymer melted material including an effective substance and forming between a belt and a roller or between two belts. CONSTITUTION: A mixing and pushing out machine 1 is provided with plural hoppers 2, hoppers supplying solid composition and liquid composition of a mixed substances if necessary and a pipe which supplies an inert gas and performs deaeration. It is provided with further one or more nozzle 3. Forming elements (a roller and a belt or a pair of belts) are desirable to contain a cooling device generally used which cools to 10 to 20 deg.C by cooling liquid. If plural nozzles are installed, forming dents are provided on a roller and/or a belt or (in case of a pair of belts) on one or both belts, and the dents are one row or plural rows and run in circulation. It is desirable to contain an exfoliation roller in order that the formed tables are removed completely from forming dents without damage at the end part of the cooling zone.

    Abstract: PURPOSE: To simplify the tablet stamping method, by pushing out a medical mixture containing a polymer binding agent and forming the materials still plastic into solid type medical tablets by a table stamping machine generally used at 25 deg.C. CONSTITUTION: Melted materials are introduced into the die of a tablet stamping machine by a transport member which can be heated and next pressed and cooled in a generally used method. Still plastic and viscous materials with high temperature can also be directly measured and supplied to the die of the tablet stamping machine by a nozzle and a measuring means. Afterward, the press forming is made together with cooling in a generally used method. Just after pushing out, still hot and plastic or viscous materials are pressed and formed into solid type tablets of medical forming substance at 25 deg.C. The medical mixture to be pushed out are mixtures of one kind or plural kinds of pharmaceutics effective substances and one kind or plural kinds of supplementary agent generally used for medical tablets manufacturing. These are one kind or plural kinds of polymer components, become a paste or viscous state by melting or softening, therefore, is possible to be pushed out.
