摘要： A solution containing a target compound is passed through a trap column (14) to capture the target compound in the column (14). Thereafter, wash water is introduced in the trap column (14). Then, the setting of a six-port valve (7) is changed and an on/off valve (6) is opened to introduce nitrogen gas through a supply-side passage (8) in the trap column (14). In this stage, the nitrogen gas is warmed by means of a heat-exchange block (10), and the trap column (14) is warmed via a column rack (15). Any water remaining in the trap column (14) is initially thrust upwards by the nitrogen gas, to be extruded from an exit edge (14b) and discharged through a discharge-side passage (20). Furthermore, any water adhering to adsorbent or the inner wall surface of the trap column (14) is quickly vaporized and carried away by the nitrogen gas. In this manner, any water remaining in the trap column (14) can be rapidly removed, so that no water will be included in an eluate in the subsequent stage where a solvent with a strong elution power is introduced into the trap column (14) to collect the eluate. Thus, the eluate is rapidly vaporized and dried, so that the target compound in solid forms can be efficiently collected.
摘要翻译： 含有目标化合物的溶液通过捕集塔（14）以捕获柱（14）中的目标化合物。 此后，将洗涤水引入捕集塔（14）中。 然后，改变六口阀（7）的设定，开通开闭阀（6），将氮气通过捕集塔（14）内的供给侧通路（8）引入。 在这个阶段，氮气通过热交换块（10）加热，并且捕集塔（14）通过柱架（15）加热。 残留在捕集塔（14）中的任何水最初被氮气向上推动，从出口边缘（14b）挤出并通过排放侧通道（20）排出。 此外，附着于吸附剂或捕集塔（14）的内壁表面的任何水都被氮气迅速气化并带走。 以这种方式，可以快速除去残留在捕集塔（14）中的任何水，使得在后续阶段，洗脱液中不会含有水，其中具有强洗脱力的溶剂被引入捕集塔（14） 收集洗脱液。 因此，洗脱液迅速蒸发并干燥，从而可以有效地收集固体形式的目标化合物。

摘要： An optical variable attenuator has a planar waveguide, which is provided with optical waveguides forming an input optical line A and an output optical line B. A cantilever is disposed at the upper face of the planar waveguide, whereas a movable mirror for reflecting light passing through the input optical line A toward the output optical line B is secured to the leading end part of the cantilever. An electrode is disposed at the upper face of the planar waveguide. The cantilever and the electrode are connected to each other by way of a voltage source. The voltage source applies a voltage between the cantilever and the electrode, so as to generate an electrostatic force therebetween, which flexes the leading end side of the cantilever toward the electrode. As a consequence, the movable mirror moves toward the electrode.

摘要： The present invention relates to an optical transmission system and a channel assigning method with structure to reduce dispersion of power levels among signals dropped at respective signal branchpoints on an optical transmission line out of signals of multiple channels amplified in an optical amplifier. The optical transmission system has an optical transmission line in which signals of multiple channels propagate, an optical amplifier provided on the transmission line, and a plurality of signal branchpoints disposed on the downstream transmission line in which the signals of the channels outputted from the optical amplifier propagate. Each of the signal branchpoints drops a signal of a channel with a lowest power level out of arriving signals in the channels. This reduces the dispersion of power levels among signals dropped at the respective branchpoints, as a whole of the optical transmission system.
