Molecules of a specific species can be selectively excited among molecules of a plurality of species that show only a slight difference of mass. Energy levels can be displayed on a graph where the horizontal axis indicates excitation energy. Assume an instance where an electromagnetic wave showing a comb-shaped spectrum having a plurality of narrow bands as indicated by Pthrough Pand tuning with excitation energies corresponding to the rotational levels of molecule X is irradiated onto the molecule X. The molecule X can sequentially make transitions to higher energy levels by using an electromagnetic wave showing such a comb-shaped spectrum. The energy levels of molecule Y are not synchronized with the comb-shaped spectrum. The two ranges of Ythrough Yand Ythrough Yoperate as gates and the molecule Y cannot make transition from a rotational level to another when a gate is found between them.

Selective molecular excitation method and isotope separation method using the same, isotope analysis method, selective molecular excitation apparatus and isotope separation apparatus

A braided structure forming method suitable for forming a braided structure of a complicated structure capable of serving as the core of FRP and FRTP, in which a speed of pulling up or down a braided structure is varied in process with time to vary the structural density thereof.

Braided structure forming method

Multi-layer tubular braided structures are produced by apparatus including a plurality of generally concentric pairs of serpentine, intersecting bobbin carrier-guiding tracks. A bobbin carrier driving gear group is associated with each pair of tracks, adjacent gear groups meshing at a plurality of bobbin carrier crossover points. According to the method, multi-layer tubular braided structures are produced by circulating a first group of bobbin carriers exclusively along one track of a first pair of tracks, circulating a second group of bobbin carriers exclusively along one track of a second pair of tracks, and circulating at least one other group of bobbin carriers exclusively along at least portions of the other tracks of said pairs of tracks via the crossover points.
