Intensive technological research on the Dry-bag CIP equipment was carried out to improve the dimensional accuracy and the productivity. The rubber mold design technology using FEM simulation during pressing was introduced, in order to achieve higher dimensional preciseness, and criteria for the selection of the In-line type or Off-line type, were established based on the powder flowability index proposed by Carr. Based on these research results, high productivity Off-line Dry-bag CIP equipment, which can realize good dimensional accuracy with high productivity, was developed even for non-granulated powders with poor packing density.

A bulk porous composite with plantinum nano-dispersion was synthesized in air atmosphere through the combination of several in situ reactions, including the pyrolysis of . A mixture of (dolomite), , and LiF (0.5 wt%, as an additive) was cold isostatically pressed at 200 MPa and sintered at for 2 h. The porous composite ( : Pt=99 : 1 in volume) had a uniformly open-porous structure (porosity: 56%) with three-dimensional (3-D) network and a narrow pore-size distribution, similarly to the porous composites reported before. Catalytic Properties (viz., NO direct decomposition and NO reduction by ) of the composite were investigated up to . In the absence of oxygen, the NO conversion rate reached ~52% for the direct decomposition and ~100% for the reduction by , respectively. The results suggest the possibility of the porous composite as a multifunctional filter, i.e., simultaneous hot gas-filtering and in one component.

While the period of high growth of Japanese economy, infrastructures were actively constructed. Now the structures are aged and its evaluation of integrity is one of significant topics to keep its serviceability and safety in Japan. Although the authors have been studied on tomographic techniques that are on the basis of elastic wave propagation for the evaluation, elastic wave difficultly propagate inside of structures if the structures are covered by stiff materials, e.g. steel reinforcement, and evaluation of integrity of the structures is difficult as consequence. Further, electromagnetic waves have been widely used for the inspection of concrete structures as well. However, dissipation rate of the electromagnetic waves is generally high in metals, and it is also difficult to penetrate inside of the structures. On the other hand, neutron beam is known as a radioactive ray which permeability is high and it would be applicable for the inspection of inside of the concrete structures. Thus, in this study, permeability of neutron beams to concrete specimens is discussed as preliminary study for establishing the inspection technique of concrete structures with neutron beam.
