    摘要： The present invention, using a readily available sulfated chitin as an adsorbent, can permit platelet factor-4 to be recovered through specific adsorption from a solution containing the same factor, in by far increased yields as compared with the conventional process utilizing a heparin-immobilized affinity column, and provides the process for isolating, through purification platelet factor-4 which is suited for a commercial-scale, mass production process, wherein there can be offered the advantages of utilization of more readily available sulfated chitin, simplified procedure and improved production yields for the objective substance.

    摘要： Disclosed is an electrode for electrical discharge used for diesinking, comprising an electrode member produced by subjecting a base and binder of gypsum hemihydrate powder and a filler of conductive metal powder to modeling and/or molding and setting into a desired form of electrode, and followed by plating the electrode member with a conductive metal; and a process for manufacturing the same, wherein a gypsum hemihydrate powder, a gypsum dihydrate powder in an amount of 1% by weight of the gypsum hemihydrate powder and a conductive metal powder are kneaded in vacuo, and water is added thereto to continue further kneading in vacuo, followed by casting into a mold having a predetermined shape transferred thereon to carry out hydration, molding and setting to provide an electrode member; after the electrode member is dried, it is plated with a conductive metal to enhance mutual continuity in the conductivity of the former conductive metal powder and also to form a thin metal layer on the surface of the electrode member. Since the present electrode for electrical discharge machining is based on a gypsum, even one having a subtle and complicated shape can easily be produced using an easy-to-make mold made of a silicone rubber and the like with high accuracy at low cost, so that it is particularly suitable for producing dental crown and bridge one by one. Further, the strength of the electrode is enhanced synergistically by the base of gypsum hemihydrate and the conductive metal layer formed on the surface of the electrode member, allowing precise electrical discharge machining of hard materials such as titanium at the desired speed which was impossible by use of the conventional electrode impregnated with a conductive solution containing a graphite and the like dispersed therein instead of the plating treatment.
