Abstract: A polymer which contains amorphous aluminosilicate particles holding metal ions having a bactericidal action is physically stable and enables an ideal antibacterial or bactericidal action by the antibacterial metal ion in an excited state. The polymer is produced by mixing an organic polymer with said amorphous aluminosilicate solid particles before the polymer is molded. alternatively, the polymer is produced by molding an organic polymer containing amorphous aluminosilicate solid particles, and treating the molded organic polymer with a solution of a water-soluble salt of a metal having a bactericidal action, thereby allowing the metal ions to be held on at least some of the amorphous aluminosilicate solid particles.

Abstract: A method for fabricating a superconductive film com­posed of a RE₁Ba₂Cu₃O x  compound, or a (Bi·Sr·Ca·Cu·O) com­pound. Oxide or carbonate of the component material, namely Y₂O₃, BaCO₃, and CuO are mixed with a mixing rate of 1:2:3 in atom, according to the chemical formula of RE₁Ba₂Cu₃O x , and sintered to create a rhombic perovskite structure. The sintered mixture is powdered again, and further added powder of Y₂O₃ with a rate of 4-6 parts of Y, and 1 part of metal­lic Cu powder each for 1 part of Ba, and sintered again. Such sintered pellet is used for the source (3) of electron beam evaporator. By doing so, the rhombic perovskite structure is transferred to the film, and the added materials supple­mented the loss of these elements caused by the electron beam evaporation. For the (Bi·Sr·Ca·Cu·O) compound, a sintered pellet composed of a mixture of one part of BiO, 3-15 parts of SrCO₃, 4-30 parts of CaCO3, and 2-5 parts of CuO, each in atomic ratio of Bi, Sr, Ca, Cu is used.

Abstract: A method for multicast communication wherein a multicast message is distributed to all the nodes (101-118) in a multicast range. If a multicast message has a multicast range which is larger than one link in the network then the message is forwarded along a unique set of pathways through the range. The unique set of pathways is called a multicast spanning tree and is unique to all nodes which can communicate directly by virtue of a list of known nodes. The network is divided into areas (130-133) each of which contains a group of directly communicating nodes (123, 125, 127). A group of nodes (121-127) designated as level two nodes facilitates communication between the nodes in different areas.
