Modern day helicopters are frequently required to operate close to non-uniform ground surfaces. During operations above a moving ship deck, it can be foreseen that the hovering performance of the rotor has very different behavior compared with the cases of hovering above stationary flat ground plane. In this report, the hovering performance of the rotor above the moving ground in full ground effect is experimentally studied in order to provide qualified database for the validation of analytical study on dynamic ground effect. The moving ground is simulated by means of harmonic rolling and heaving motions of ground effect plate with variable amplitude and frequency. The thrust, torque and blade flap angle of the rotor were measured at rotor height from 0.4 to 1.5. It is shown that motion types of the ground and the amplitude and frequency of the moving ground have important effects on the variable loads in and out of the rotor disk in dynamic ground effect.

The main objective of this paper is to discuss the history of shrines in Karafuto based on materials from the pre-Russo-Japanese War period before Japan took over southern Karafuto. A comparison of shrines in Karafuto and other areas found three major characteristics of Karafuto. First, religious activities were allowed in the name of religious freedom between the invasion of the Soviet military and the repatriation of Japanese people. Second, Japanese made up a large majority of the population. Third, deities that people worshiped were diverse. From the second half of the Edo period, shrines‒mainly those enshrining Benten or a goddess of water and fortune‒started to be built in Karafuto. Japanese there engaged in religious activities even when Karafuto was inhabited by both Japanese and Russians from the end of the Edo period to the beginning of the Meiji period. It was confirmed that these shrines existed until the middle of the Russian occupation from 1875 to 1902. After southern Karafuto became Japanese territory as a result of the countryʼs victory in the Russo-Japanese War, many Japanese moved there and built new shrines. The vast majority of the population in Karafuto was Japanese, and shrines were built according to religious practices in mainland Japan. Therefore, shrines in the region have a historical background different from that of other overseas shrines in a narrow definition. It is unique that Japanese people in Karafuto were allowed to be involved in religious activities during the one and a half years between the Soviet invasion in August 1945 and the second repatriation of Japanese in January 1947. 279 shrines including those under the supervision of the colonial government of Karafuto and others managed by local communities were places of worship for Japanese in the area, despite differences in size and rank. Karafuto Shrine-a Japanese government-sponsored great shrine established in 1910 with construction completed on August 22, 1911‒was run by the national government but had strong commonalities with those established by local people. When comparing shrines and temples in terms of numbers of structures and monks, we realize that temples were far more powerful and influential. After Japanʼs defeat in World War II, shrines disappeared from Karafuto. They were founded for Japanese and thus perished when they left the region. In this paper, the history of shrines in the Northern Territories will be introduced based on materials from the Edo period. These materials indicate that no shrine in the territories was recognized by the Japanese government, and that local Japanese strived to have their shrines recognized.論文

比較的稀な限局的動脈狭窄性疾患のひとつである膝窩動脈外膜嚢腫の 1 例を経験した.症例は63歳女性で右下肢の間歇性跛行にて発症した.右側ABIは0.93と軽度低下を認めた.下肢造影CTにて右膝窩動脈に高度狭窄と血管内腔に突出する嚢胞状病変の所見を認めた.下肢MRI長軸像では右膝窩動脈周囲に縦長の嚢胞様腫瘤を認め,膝窩動脈を狭窄させていた.同腫瘤はT1強調像で低信号,T2強調像で高信号に描出されていた.短軸像では,花弁状に嚢胞状病変が膝窩動脈を取り囲んでいた.以上より外膜嚢腫と診断した.術前に血管エコーで嚢腫直上にマーキングを施した後,小切開にて外膜切開術を行った.膝窩部の可動域制限を心配することなく良好な経過を得た.本疾患の病態の理解が進み画像診断が向上したことにより,今後さらに低侵襲手術の対象となると考えられる.

This study focuses on the historical background, current conditions, and future directions of preserving and utilizing Japanese cultural and historical heritage in Sakhalin, formerly Karafuto, during the Japanese occupation (1905-1945). It also provides the first detailed descriptions of the remains of shrines. A project to preserve Japanʼs historical and cultural heritage in Sakhalin met with negative reactions at first. But since Soviet leader Mikhail Gorbachev introduced perestroika reforms in 1985, Japanese rule has been recognized as part of Sakhalinʼs history and various exchange programs have been organized, such as cultural exchanges between the Sakhalin Regional Museum and the Historical Museum of Hokkaido (now Hokkaido Museum) and economic exchanges between Sakhalin and Hokkaido. Moreover, the governor of Sakhalin issued the law to protect historical and cultural assets in 1999, and an academic conference titled "Sakhalinʼs Culture : Past Experiences and Future Perspective" was held the following year. Since then, international symposiums on the protection of historical and cultural heritage during the Karafuto era have taken place regularly to promote various projects to compile a list of Japanese heritage properties ( existing buildings and remains) in Sakhalin, evaluate them for preservation, and publish historical documents. These projects include, for example, transferring guardian lions in Karafuto Gokoku Shinto Shrine to the Sakhalin Regional Museum, restoring a victory monument in Tomarioru Shrine, and preserving the building of the former Hokkaido Takushoku Bank Odomari branch. A list of the remains of shrines suggested for restoration, maintenance, and installation of information boards includes Karafuto Gokoku Shinto Shrine in Yuzhno-Sakhalinsk (formerly Toyohara City); a monument for the landing of the Japanese Sakhalin Expeditionary Army in the Merei area and a monument for loyal souls in Nagahama Shrine in Korsakov (formerly Odomari); Higashi Shiraura Shrine in Dolinsk (formerly Ochiai); a monument for the opening of Sakhalin Island in the Shiranushi area and Honto Shrine in Nevelsk (formerly Honto); Chiritoru Shrine in Makarov (formerly Chiritoru); Esutoru Shrine in Uglegorsk (formerly Esutoru); and Maoka Shrine in Kholmsk (formerly Maoka). The information boards will explain the names of shrines and deities, founding years and building exteriors. These projects will help Sakhalin play a more important role as a crossroad connecting islands in Asia-Pacific countries and the European continent, promote exchanges among peoples and nations, and develop new approaches to preserving Japanese heritage in Sakhalin.論文

As for traction motor for railway vehicle, over fifty thousands DC motors are used only in Japan Railways Companies. Insulation breakdown is one of the biggest problem for traction motor and various kind of insulation tests are carried out for every motors at the time of overhaul. The methods and the way of these insulation tests are determined about thirty years ago or more. Materials of insulation and how to compose these materials have progressed in these days. So it is important to research what kind of insulation test is suited for traction motor.This time we made a research to estimate various kinds of insulation tests by carrying out dielectric breakdown test for over 150 motors. And this paper describes the result.

探査機が月や火星などの天体に着陸する際に、残留水平速度がある場合や斜面・岩などの存在する不整地へ着陸する場合においても転倒しない着陸システムについて研究を行った。探査機の着陸脚と天体表面の動的モデルを構築し、数値シミュレーションにより探査機の動的挙動を解析した。その結果から、着陸脚をセミアクティブに制御する方法を提案した。すなわち、伸縮式着陸脚の減衰係数を可変にすることができるデバイスを追加し、探査機の角速度と着陸脚の伸縮方向の符号の積に応じて当該脚の減衰係数を増減させるという方式である。本方式により耐転倒防止能力が大幅に上がることを数値シミュレーションおよび着地実験により検証した。
