Abstract: An improved process for producing a silicon carbide ceramic micro tubes (SiC micro tube) from a silicon-based polymer fiber by applying an ionizing radiation such that the surface part of the fiber selectively undergoes oxidative crosslinking, extracting the uncrosslinked core part of the fiber with an organic solvent to form a hollow fiber, and firing it in an inert gas is characterized by using a polymer blend of polycarbosilane and polyvinylsilane as the silicon polymer or applying the ionizing radiation to the silicon-based polymer fiber as it is cooled. The two methods may be performed either individually or in combination to produce tubes with their wall thickness controlled at a desired value in the range of 2-10 ?m although this has been impossible to achieve in the prior art.

Abstract: To obtain high-directivity, stable, and high-intensity ion beam. An ion beam irradiator 10 is constituted by a combination of a laser-driven ion/electron generator 20 and an ion transporter 30 and is configured to guide ion beam with low directivity emitted from the ion/electron generator 20 to the output end while increasing the directivity of the ion beam or focusing the ion beam at the ion transporter 30. In the ion transporter 30, an electron absorber 33 is provided around a beamline 31 at a location on the upstream side in terms of the flow of the ion beam relative to multipole magnets 32. The electron absorber 33 is formed of a material (e.g., polytetrafluoroethylene (PTFE)) that can effectively absorb high-energy electrons. The electron absorber 33 is surrounded by an X-ray shield 34 made of heavy metal such as lead.

Abstract: 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 P1 through P14 and 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 Y4 through Y7 and Y12 through Y15 operate as gates and the molecule Y cannot make transition from a rotational level to another when a gate is found between them.

Abstract: The current methods of removing the surface-deposited layer contaminated by radioisotopes has the disadvantage of rigorous applicability conditions in such terms as the substance to be treated, the area and the shape, so the scope of their applicability is quite limited; in addition, 100% decontamination is not guaranteed and in spite of more than 50% that can be decontaminated, a greater part of the deposited radioisotopes remain unremoved, limiting the decontamination performance of the methods. Parts, structural components, etc. that have their surfaces contaminated by radioisotopes in the accelerators, nuclear reactors, RI product manufacturing factories, nuclear fuel factories, nuclear fuel reprocessing factories, etc.
