  • Adsorption agent for noble metal, method for manufacturing the same, and method for recovering noble metal
    Patent number: 8936666
    Abstract: A noble metal adsorption agent includes algae or residue of algae having an amino group as a functional group. A noble metal is retrieved by a method including: adsorbing the noble metal on the noble metal adsorption agent; and retrieving the noble metal. The noble metal is solved in a liquid. Thus, by using the noble metal adsorption agent, the noble metal is selectively retrieved.
    Type: Grant

  • Adsorbent and method of collecting precious metal using the same
    Patent number: 8535625
    Abstract: An adsorbent contains a carbohydrate having an ether linkage. Alternatively, an adsorbent contains a carbohydrate having a cross-linkage formation produced by a dehydration reaction using a strong acid. In collection of a precious metal using the adsorbent, the adsorbent selectively adsorbs a precious metal dissolved in a solution.

  • Injection molding machine
    Patent number: 5007822
    Abstract: As injection molding machine in which a plurality of stationary molds (29) are securely disposed in a row on a stationary platen (3) and transversely extending parallel to one another, and a moving mold (6) to be coupled with the stationary molds is supported as a unit displaceable in a lateral direction in a mold holder with regard to a moving platen (4), by coupling and clamping the moving mold (6) and one of a plurality of stationary molds (29) together, injection molding is accomplished, thus by changing stationary molds one after another and clamping the moving mold, the injection molding is accomplished to obtain multi-colored or multi-material molded products. The moving mold protrudes a small distance beyond the end surface of the mold holder facing the stationary mold to minimize flash produced by slanting due to off-center pressure on the molds.
