Unspiked K-Ar dating procedure enables the correction for mass fractionated initial 40Ar/36Ar ratios, and has been successfully applied to young volcanic samples, especially younger than 0.5 Ma. We reconstructed the growth history of western to central part of Kuju Volcanic Group based on the unspiked K-Ar age data. The unspiked K-Ar ages for the small andesitic-dacitic volcanoes of Stage 1 (Kutsukakesan Volcano, Iozan Lava, Kuroiwasan Volcano, Narukoyama Volcano) provided with two age group of ca. 160-150 and ca. 90-80 ka, suggesting that Stage 1 may be divided into at least two sub-stages. During Stage 3 after the largest eruption associated with Handa pyroclastic flow deposit, some lava domes and stratovolcanoes in the central part (Ogigahana Volcano, Nakadake Volcano and Mimatayama Volcano) were built up from ca. 54 to 34 ka, which is older than the previous interpretation.Based on these K-Ar ages and estimated volume for each volcanic unit, we calculated the magma discharge rate during each volcanic stage and the whole period of the volcano history. The calculated magma discharge rate for Stage 1, 3 and 4 are 0.09, 0.12, 0.18 km3/ky, respectively, showing that the activity has slightly increased. The rate of 0.12 km3/ky for the whole period is similar to that for Aso and Unzen volcanoes lie to the west of this volcano.

On the 24th July, 2012, a large scale explosion occurred at Minamidake Summit crater of Sakurajima volcano, for the first time in last 1.5 years. This eruption is characterized by a clear, large preceding inflation ca.22 hours before the eruption. The juvenile glass particles in the volcanic ash of this eruption have less amount of microlite than those of Showa crater. The crystal size of microlite is also smaller. In contrast, their microlite number densities (MND) of plagioclase and pyroxenes are similar to those of Showa crater. According to the results of the decompression experiments by previous studies, the variations of crystallinity of microlite with the constant MND can be explained by the difference in the length of the duration for decompression, and/or the duration until the quench after the decompression. Considering these results, the juveniles of the summit eruption are derived from the eruption induced by relatively rapid decompression with rapid quench, and the juveniles from Showa crater are the products of the eruptions accompanied with the relatively slower decompression and/or the longer annealing after decompression. Therefore, it is interpreted that the 24th July, 2012 eruption was caused by rapid magma ascent with much shorter stagnation in the conduit. In contrast, the eruptions at Showa crater might have been induced by slower magma ascent and/or longer stagnation at a shallower depth of the conduit. This interpretation agrees with the data of geophysical observations. On matrix glass chemistry, juveniles of this summit eruption show the distinct trend from those of Showa crater. This feature can be produced by the difference in mode of microlite, which are crystallized during magma ascent. Accordingly, it is possible to evaluate the difference in magma ascent process, using the matrix glass chemistry.

水道水を電気分解処理して得られたアルカリ性水の炊飯水としての有効性について検討を行い,以下の結果を得た.(1) 白米と浸漬水の総体積変化は,アルカリ水,原水(水道水),酸性水の順に大きくなった.任意のpHに調整された試験水を用いた実験より,白米の膨潤度はpHの影響を受けていることが確認された.(2) 画像処理装置により炊飯米形状を二次元的に計測し,面積はアルカリ性水,酸性水,原水の順に大きく,アルカリ性水のものは原水のものよりも約4.5%の差がみられた.(3) 三粒法により各米飯のテクスチャーを測定したが,粘りと硬さの比がアルカリ性水,酸性水,原水の順に大きな値をとった.アルカリ性水により処理された炊飯米のテクスチャーが高い原因として,炊飯米表面の糊化した澱粉量が多いことによるものであることが考えられた.洗米において白米からの澱粉の溶出量は,アルカリ性水処理によるものが最も高く,炊飯米においても同様であった.この原因として,洗米では高いpHや界面活性的な働きが白米表面物質の遊離を促進するため,また炊飯米では高いミネラル濃度が澱粉細胞の細胞壁に沿って存在するタンパク質の可溶性を促進するためと推察された.

Canine parvovirus type 2 (CPV-2) is the main etiological agent of viral enteritis in dogs. Actually in literature, CPV-2 has been reported with clinical signs that vary from the classical disease, and immunochromatography test and PCR technique have been introduced to veterinary hospitals to confirm CPV-2 diagnosis and other infections. However, the reliability of these techniques has been poorly analyzed. In this study, we evaluated the sensitivity and specificity of veterinary clinical diagnosis, immunochromatography test and PCR technique. Our data indicate that variations in the clinical signs of CPV-2 complicate the gathering of an appropriate diagnosis; and immunochromatography test and PCR technique do not have adequate sensitivity to diagnose positive cases.

We investigate future changes in winter precipitation around Japan and their uncertainties using the downscalings of a non-hydrostatic regional climate model (NHRCM) with 20-km grid spacing according to global climate projections. The global climate projections were conducted by the atmospheric general circulation model with three patterns of sea surface temperature changes in the Coupled Model Intercomparison Project Phase 5 under the Representative Concentration Pathway 8.5. Moreover, three cumulus convective parameterizations were applied in the present and future climate experiments. The ensemble mean of nine future NHRCM experiments shows decreases in the winter precipitation on the coast of the Sea of Japan and over the Pacific Ocean in the south of the Japanese archipelago. The former decrease in precipitation results from a weakened winter monsoon. The latter corresponds to changes in extratropical cyclone number around Japan, which have a large uncertainty. On the other hand, winter precipitation increases over the northernmost part of Japan (Hokkaido) and the northeastern Asian continent. The strengthened northwesterly around Hokkaido, which results from the reduction of sea ice in the Sea of Okhotsk, causes increased precipitation in the inland area of Hokkaido. In addition, moistening due to global warming relates to increased precipitation in extremely cold regions. These signals are common to most experiments.

The effect of the Quasi-Biennial Oscillation (QBO) and the El Niño Southern Oscillation (ENSO) on the 11-year solar cycle modulation of the winter-mean North Atlantic Oscillation (NAO) is examined through analysis of observational data from 1958 to 2000. It is found that the solar cycle modulation of the NAO is more strongly enhanced in the westerly phase of the 50-hPa QBO wind and the cold phase of ENSO, although separation of these effects is statistically difficult. On these phases, the signal of the winter-mean NAO extends more to the upper stratosphere and summer-AO reappears more strongly in high solar years, whereas the signal is weaker throughout in low solar years.

This paper deals with the method of controlling an A/K prosthesis which allows disabled persons to ascend a staircase. Since conventional A/K prostheses are capable of only the function of walking on a level surface, disabled persons wearing conventional A/K prostheses have been compelled to walk on stairs with unnatural posture. The research study of developing powered A/K prostheses has the important themes of not only developing the mechanism of the prosthesis but also devising the controlling method. By measuring the axial forces acting on the socket ; which is the man-machine-interface, during walking, using the six axis force-moment sensor, the torque of a disabled side hip joint was calculated. We devised the control method using this torque as the control signal. Results of clinical walking experiments showed that a subject wearing the A/K prosthesis was able to walk with a joint angle pattern similar to that of unaffected persons. Furthermore, from the results of the inverse dynamics analysis, the subject was found to generate a similar torque pattern and power pattern at his disabled side hip joint. Thus the effectiveness of the controlling method proposed in this study was confirmed.

Descriptions are made of the theory and practice of the double spot high output ballast in which a fluorescent lamp is used.The theory states that, when the phase of the filament terminal voltage runs 90 degrees ahead of the tube voltage, the potential difference becomes equal between the opposing electrodes at both ends of the fluorescent lamp, thereby giving rise to the double spots, while the fluorescent lamp is in operation.Not only this fact in proved true, but also the quantitative reasoning on the formation of double spots is presented and backed up by some test data.

Report is made on the propagation of fractures in mild steel plates caused by impact of high speed bullets with observations on twinning of ferrite grains and distortion of twin lines. (1) On the propagation of fracture For as-rolled plates, resistance to fracture is larger in the direction of the rolling than in the direction perpendicular to it. This difference is lost by annealing. In annealed plates, the crack is apt to take its path along pearlite grains. In as-rolled plates, crack with bifurcation is observed. (2) On the deformation after twinning Micro-photographs show that the twinning is completed at the moment of impact followed by intense distortion of twin lines with the flow of ferrite grains. From this fact, it is denied that the twinning would proceed simultaneously with the brittle-type fracture.

This study attempts to establish the limits of the Chinese Communist Party leadership’s perception of Japan based on negotiations over the Fourth Japan-China Private Trade Agreement and the Nagasaki national flag incident. It explains the underlying rationale for and reason why the Chinese decided to break off relations with Japan, what their perceptions of the situation were, and what they had failed to perceive. In addition, this study analyzes the interaction between Chinese intelligence acquisition, data analysis and the perception of Chinese policy-makers. When the trade negotiations began in Beijing in September 1957, China’s policy-makers, albeit wary of the Kishi cabinet’s attitude towards China, were optimistic about the prospects for Japanese domestic approval of Sino-Japanese trade; China’s negotiators were not ready to compromise. After the negotiations broke down, demand for trade with China grew strong in Japan and the Kishi cabinet actively worked towards concluding an agreement, whereby the Chinese leaders, although holding fast to certain principles, displayed a more flexible stance. Negotiations were reopened in February 1958, but there was no change in the ambivalent position of the Chinese policy-makers on Japan and their negotiator won some concessions from the Japanese side. During these negotiations, any arbitrary analysis of information obtained by China’s pro-Japan intelligence agencies was checked and nothing suggested that the policy-makers entertained any noteworthy misunderstandings of Japan. China turned to stronger methods when Taiwan’s objection to the Fourth Japan-China Trade Agreement developed into a dispute between Japan and Taiwan. At the time of Japan’s general elections, Chinese policy-makers tried to encourage a more China-friendly public opinion by criticizing the policy towards China that the Kishi cabinet was practicing, thereby hoping to alter the Kishi government’s position on China. These moves were consistent with China’s existing policy of “Japan neutralization”. However, there was limited domestic criticism of how Kishi dealt with China, a fact that Chinese intelligence agencies were to some extent informed of. Motivated by a disapproval of the Kishi cabinet and high hopes for Sino-Japanese trade, they made arbitrary deductions based on gathered information suggesting that China’s hard-line stance was in fact bringing results. In these circumstances, Chinese policy-makers adopted an even tougher position on Japan in the wake of the Nagasaki national flag incident and decided to break off relations. The Chinese did not intend a complete and permanent cessation of relations, but rather wanted to apply pressure on Kishi. As such, the decision was in line with China’s policy of “Japan neutralization”. On the other hand, Kishi perceived China’s hard-line stance as interference with Japan’s general elections, and chose to observe calmly how events unfolded. Japanese opinion continued to support Kishi government policies. However, China’s pro-Japan intelligence agencies disregarded this fact and produced arbitrary intelligence that China’s hard-line stance was in fact bringing results. Hence Chinese policy-makers persisted with their hard-line stance and did not modify their “Japan neutralization” policy. In retrospect, this chain of events suggests that one cause for China’s failed Japan policy was the failure of its intelligence agencies to comprehend that mounting Japanese domestic demand for trade with China had the potential to alter Japan’s foreign policy. Chinese intelligence analysis had backed up its policy-makers’ hard-line stance, and hence China continued to maintain the ambition of achieving its “Japan neutralization” policy. The limited insight of China’s Japan-related intelligence agencies was the result of the following three factors: firstly, their abilities to collect and analyze intelligence were not yet fully developed;
