In this study, the effect of air space in waterproof sealed case of undersea magnetic field resonance type wireless power transfer (WPT) is reported. It has been reported that the transmission power is increased by the air space between the transmitter and receiver coil in the waterproofing case and the wall surface of the case. We evaluated the dependence of the thickness of the air space from measurement and magnetic field analysis. The measurement and magnetic field analysis results indicated the similar tendency to increase the transmission power by 9.8% with the 10‐mm air space at the transmitter side and the 30‐mm air space at the receiver side. 相似文献

The degradation of 1,4-dioxane was investigated on a laboratory scale. The extents of degradation and/or removal of 1,4-dioxane by ozonation at pH 6–8, UV irradiation, aeration, and addition of H2O2 were very limited. On the other hand, the degradation of 1,4-dioxane by O3/UV and O3/H2O2 was accelerated compared with the above respective methods. The amounts of 1,4-dioxane degraded per amount of ozone consumed in O3/UV and O3/H2O2 were also higher than in ozonation. The amount of 1,4-dioxane degraded in O3/UV was affected by the intensity of UV irradiation, and that in O3/H2O2 was affected by the amount of H2O2 added only in the case of a high initial concentration of 1,4-dioxane. 相似文献

An improved light-weight Compton camera exhibiting low power consumption was developed to be mountable on an unmanned helicopter to detect cesium radiation hot spots and confirm the decontamination effect of cesium-affected areas. An increase in the Ce:Gd3(Al,Ga)5O12 scintillator array from 4 × 4 to 8 × 8 and expansion of the interlayer distance enhanced the detection efficiency and angular resolution, respectively. Measurements were performed over the Ukedo riverbed in Namie, Fukushima Prefecture (Japan). The helicopter's flight path and speed were pre-programmed to lines interspaced by 5 and 10 m intervals and 1 m/s, respectively, facilitating measurements over areas of 65 × 60 m2 and 65 × 180 m2 at a height of 10 m for approximately 20 and 30 min, respectively. Results provided accurate ambient dose equivalent rate maps at a height of 1 m with an angular resolution corresponding to a position resolution of approximately 10 m from a height of 10 m. Hovering flights were executed over hot-spot areas for 10–20 min at a height of 5–20 m. Gamma-ray images of these hot spots were obtained using a reconstruction software. Comparison between position-shifted measurement results showed that the angular resolution coincided with that evaluated in the laboratory (approximately 10°). 相似文献
