    摘要: A method for preparing a copper-containing hydrogenation reaction catalyst includes the step of reducing a formed precursor of a copper-containing hydrogenation reaction catalyst with hydrogen gas or a mixture of hydrogen and inert gas by liquid phase reduction in a stream of a solvent. The reductive activation is carried out by the two steps of performing the first stage of liquid phase reduction by which the catalyst precursor is activated in the temperature range of from 20.degree. to 140.degree. C. so that at least 10% by weight of the copper oxide contained in the catalyst precursor can be reduced by the time when the temperature passes 140.degree. C., and then performing the second stage of liquid phase reduction by which the catalyst precursor is further activated in the temperature range of from 140.degree. to 250.degree. C. The catalyst thus obtained has markedly improved catalytic activity and selectivity. An alcohol of high quality can be obtained at a high productivity using the catalyst in a fixed bed continuous reaction system.

    摘要: A plurality of crossconnect systems are respectively arranged at branch points of a network transmission line system. Each of the crossconnect systems includes a first setting unit, a second setting unit, and a checking unit. The first setting unit sets a primary transmission route of the network transmission lines. The second setting unit automatically searches for and sets an alternate route when a fault is detected in the primary transmission route set by the first setting unit. The checking unit checks the operation of each transmission line according to a predetermined timing.
