    Opis:
    In order to prevent hydrofoil colliding with cetaceans, the underwater speaker (UWS) has been installed to repel cetaceans. Yamada et al. (2012) analyzed and devised the UWS sound as it fits the cetaceans' acoustic properties to prevent the collision furthermore. The new UWS sound was devised and synthesized by Yamada et al. (2015) with expectation of avoiding collision with large cetaceans (Patent applied for, JP2014-171411). In this research project, the new UWS sound was investigated by the playback experiment on humpback whale (Megaptera novaeangliae) and by sighting survey in the actual hydrofoil shipping service route. As a result, a physiological and behavioral change of the humpback whale was observed in the playback experiment of the new UWS sound, and the chance of hydrofoil encountering cetaceans of the new UWS sound was smaller than that of the previous UWS sound. Therefore, the improvement of the new UWS sound was confirmed. Lastly, we wish this research project would contribute toward the safer cruise of hydrofoil in the future.

    Opis:
    In this report, we have described about new field emission array (FEA) structure built-in micro-column. This newly proposed FEA has multi-gated structured and is designed to form a crossover. We had already demonstrated the quad- and quintet- gated FEA. A crossover formation by was successfully observed for the first time. by the quintetgated FEA Furthermore electron beam lithography was demonstrated.

    Opis:
    Microcapsules containing tri-n-octylamine as an extractant with the diameter of less than 25µm were prepared by using SPG membrane emulsification and insitu polymerization method. The morphologies of microcapsules, the encapsulation efficiencies of tri-n-octylamine, the extraction properties of palladium (II) from hydrochloric acid solution and the back extraction properties of palladium (II) from microcapsules were investigated. The average diameter of obtained microcapsules was about half of the pore diameter of SPG membrane. The encapsulation efficiency of tri-n-octylamine was approximately 100% for all the microcapsules prepared in this study. Therefore, it can be said that there was practically no loss of tri-n-octylamine during the preparation of microcapsules. All microcapsules prepared in this study reached forward extraction equilibrium within 5 minutes and the forward extraction ratio reached nearly 1. The back extraction of palladium (II) from microcapsules was carried out using 0.1M-hydrochloric acid solution containing a prescribed amount of thiourea. The back extraction occurred promptly and the back extraction ratio was high enough to elute all palladium (II) out from the microcapsules. Furthermore, by repeating forward and back extraction experiments, the durability of microcapsules was examined. From the result, it can be said that tri-n-octylamine was encapsulated rigidly and there was no leakage during extraction and back extraction experiment. Thus it seemed that the microcapsules were capable to be used in a repeated operation.

    Opis:
    Large-diameter and through-hole type microcapsule with entrapped trioctylamine (TOA) as an extractant were prepared by (W/O/W) emulsification and in-situ polymerization method. The morphologies of the microcapsules, their encapsulation efficiencies for TOA, and their forward and back extraction properties for palladium(II) were investigated. The microcapsules ranged in size from 210-420 ěm. The encapsulation efficiency of TOA was approximately 100% for all the microcapsules, which indicates minimal loss of TOA during preparation of the microcapsules. Through-hole type microcapsules were obtained when inner aqueous phase contained a high concentration of sodium chloride, and at a moderate agitation speed in the first emulsification. With the through-hole type microcapsules the extraction equilibrium approached one, and the extraction rate was very high compared to other preparation conditions and (O/W) type microcapsules.

    Opis:
    We study the effects of exciton-longitudinal optical phonon interaction on the exciton binding energies in ZnS/$Mg_{x}Be_{y}Zn_{1-x-y}S$ single quantum wells. The heavy- and light-hole exciton binding energies increase to the exciton-logitudinal optical phonon interaction. The increase in the maximum heavy-hole (light-hole) exciton binding energy for x=0.74 is 68.3 meV (55.0 meV). In narrow ZnS/$Mg_{x}Be_{y}Zn_{1-x-y}S$ single quantum wells SQWs, the heavy- and light-hole exciton binding energies exceed the longitudinal optical phonon energy of ZnS when x ≥ 0.1.
