    Abstract: A mode conversion and mode separation branched dielectric waveguide element for light comprising branches having optically different characteristics which are surrounded by a medium or media having different refractive indexes from that of the dielectric material or materials forming the branches. In one embodiment, one of the surrounding media is an electrooptical crystal provided with at least one pair of electrodes near the parting portion of the branches. As a modification, the branches may be connected at the opposite ends thereof to form a by-pass construction.

    Abstract: Heavy metal adsorbents comprising granules of a mixture of nitrohumic acid and at least one binder selected from the group consisting of a carboxyl group-containing polymeric compound and a water-insoluble salt thereof. These heavy metal adsorbents are produced advantageously by either a process wherein a mixture of nitrohumic acid and a carboxyl group-containing polymeric compound is kneaded with an aqueous solution of alkali and the kneaded mixture is first subjected to an acid treatment and then shaped into granules, or a process wherein nitrohumic acid and a carboxyl group-containing polymeric compound are dissolved in an aqueous solution of alkali, the solution is acidified to form a precipitate and then the precipitate is separated and shaped into granules. The granular products thus obtained can be further improved in mechanical strength by means of a heat treatment.

    Abstract: This invention provides a method for underwater frictional welding of metallic articles, which method comprises preparatorily wrapping a heat insulating material such as tape around the periphery at the terminal face of each of the metallic articles subjected to welding, abutting under pressure the terminal faces of the metallic articles against each other and welding the confronting ends of the metallic articles by utilizing the frictional heat produced in the terminal faces by the relative rotary motion and the pressure exerted in the axial direction.

    Abstract: A composition is produced by combining one or more members selected from the group consisting of omega -vinyloxyalkyl cinnamate, omega -vinyloxyalkyl styrylacrylate and homologs thereof with a cationic polymerization catalyst. This composition is polymerized or copolymerized to form a novel photosensitive polymer. The product of polymerization or copolymerization is a linear polymer or linear copolymer in which only the vinyl group is polymerized and the photosensitive group is quantitatively retained in the side chain. This polymer or copolymer enjoys a high degree of photosensitivity and permits the photocrosslinking reaction to occur uniformly.
