摘要： After a target compound is captured by an adsorbent within a trap column (7) held by a column rack (8) in a substantially vertical position and the column is filled with water to wash its inside, dichloromethane is slowly introduced from an inlet end (7a) on the lower side by a pump (5). The water within the trap column (7) is pushed upward by dichloromethane and exits from an outlet end (7b), to be disposed of via a two-way selector valve (12) and a disposal passage (14). Dichloromethane elutes the captured target compound. Therefore, when the eluate, which initially consists of water, changes via an emulsion to dichloromethane, the eluate contains an adequately high concentration of target compound. At this point, the two-way valve (12) is switched to a preparative separation passage (13). As a result, a solution that is adequately free from water and yet contains the target compound can be collected into a collection container (17), and the target compound in solid forms can be quickly obtained.

摘要： An optical transmission path in a Raman gain module (1) for transmitting signal light input from an input terminal (1a) and Raman-amplifying the signal light by pumping light supplied from pumping light source units (21, 22) is formed by connecting in series two Raman amplification optical fibers (11, 12) having different wavelength dispersion values. According to this arrangement, wavelength dispersion in the amplifier module (1) can be controlled using, e.g., the combination of the wavelength dispersion values of the Raman amplification optical fibers (11, 12). Hence, accumulation of dispersion into signal light and signal light transmission in an almost zero dispersion state are prevented, and degradation in signal light transmission quality due to the nonlinear optical effect is suppressed.
摘要翻译：拉曼增益模块（1）中的用于传输从输入端子（1a）输入的信号光并通过泵浦从泵浦光源单元（21,22）提供的光来对信号光进行拉曼放大的光传输路径是通过连接具有不同波长色散值的两个拉曼放大光纤（11,12）。根据这种布置，可以使用例如拉曼放大光纤（11,12）的波长色散值的组合来控制放大器模块（1）中的波长色散。因此，防止了色散在信号光中的积聚和几乎为零色散状态的信号光传输，并且抑制了由于非线性光学效应引起的信号光传输质量的劣化。

A first waveguide path 11 and a second waveguide path 12 are provided on a waveguide substrate PCL so as to intersect each other at a given angle. A trench T is formed in a straight line in the surface of the waveguide substrate PCL so as to cross the central axes of the first waveguide path and the second waveguide path.

摘要： The present invention relates to an optical multiplexer/demultiplexer comprising a structure for effectively lowering the crosstalk between adjacent signal channels, thereby realizing excellent wavelength multi/demultiplexing characteristics. The optical multiplexer/demultiplexer is designed such that, while adjacent channel waveguides are allowed to have optical path length differences different from each other, effective optical path length differences become constant between optical paths traveling by way of the channel waveguides adjacent each other in optical paths including slab waveguides as a whole, whereby the structure for connecting channel waveguides to flat connecting end faces of slab waveguides can be changed arbitrarily without being restricted by multi/demultiplexing conditions. As a result, it becomes easier to design the arrangement of channel waveguides, and their layout attains a higher degree of freedom, which makes it possible to design a structure for effectively lowering the crosstalk between adjacent signal channels.
