    摘要： A process for preparing simultaneously pyridine bases including 2-methylpyridine and 4-methylpyridine, occasionally, together with pyridine from acetaldehyde and ammonia by gas phase catalytic reaction, characterized in that the gas phase catalytic reaction is conducted in the presence of a catalyst prepared by (A) incorporating at least one compound containing at least one metal selected from the group consisting of tungsten, manganese, nickel, iron, cobalt, molybdenum, uranium, lead, silver, copper and tin into silica-alumina simultaneously with preparation of the silica-alumina, or (B) subjecting silica-alumina to ion exchange with ions of at least one metal selected from the group consisting of manganese, nickel, iron, cobalt, uranium, lead, silver, copper and tin to adsorb the ions on said silica-alumina. According to the process of the present invention, there can be obtained the desired pyridine bases in high yield, whereas formation of by-products including high boiling point pyridine derivatives is remarkably suppressed. The catalyst employed in the present process has a high resistance to the reaction atmosphere.

    摘要： An optical fiber board has a substrate, optical fiber arranged as wiring on the substrate, and extension portions in each of which some optical fibers are led out from the substrate to be adjacent to each other in a row. The adjacent optical fibers at a base portion of the extension portion are not fixed to one another. The adjacent optical fibers at a forward end portion of the extension portion are fixed to one another integrally. The base portion has a predetermined length from an edge portion of the substrate.
