Spline-profile horn antennas optimized with dual conical modes
Get PDF本論文では，利得やビーム幅が周波数によって大きく変化しない多モードホーンの設計を行うため，交差偏波成分を最小にするデュアルモードの励振振幅に加えて，適切な球面波面を用いて最適化設計する方法を提案している．設計例として，比帯域32 %の周波数サンプル点で最適化した円形開口のスプラインプロファイル軸対称ホーンを示し，ビーム幅，利得，交差偏波特性の周波数特性について詳細に評価することによって提案する方法の有効性を検証している．To obtain a multimode horn whose gain and beamwidth do not significantly vary with frequency, this paper proposes optimizing the selection of the phase distribution or spherical wavefront on the horn aperture, in addition to adjusting the amplitude of the mode coefficients for minimizing cross-polarization components. As design examples, spline-profile axisymmetric horns with a circular aperture optimized at frequency points for a 32 % relative bandwidth is presented, and then the effectiveness of the proposed method is verified by thoroughly evaluating the frequency characteristics of beamwidth, gain, and peak cross-polarization level.原著論文departmental bulletin pape

American Protestant missionaries who came to Japan during the occupation period : the case of nisei (Second-Generation Japanese) Missionaries
Get PDF本研究は、占領期に来日した日系二世宣教師を事例にして、北米の日系人プロテスタント史と占領期日本プロテスタント史との繋がりを考察することで、当該時期の日米越境プロテスタント史研究に貢献することを目的とする。先ず、占領期日本における日米プロテスタント及びGHQ/SCAP によるプロテスタント宣教師受入体制の変遷を体制が整う1947年までについて概観する。次に、1945〜51年にGHQ/SCAPの承認を得て訪日した日系二世プロテスタント宣教師29人に着目し、彼(女)の特徴(国籍、性別、生年月日、来日日、活動種別、学歴、来日歴等)を、来日宣教師全体と比較し、日系二世の特徴を検討する。最後に、グレース・キョーコ・イマモト(Grace Kyoko Imamoto, 1920.1.14 - 2018.3.14)を事例に、来日日系二世宣教師の個人史を家庭環境、生活環境、強制収容、召命、来日経験、その後に分けて概観し、その顕著な特性と今後の検討課題を考察したい。This study aims to contribute to the research on the transnational Protestant history between Japan and the U.S. during the occupation period by examining the connection between the history of the Japanese American Protestants in North America and the Protestant history during the occupation era in Japan, using the Nisei (second-generation Japanese American) missionaries who came to Japan during that time as a case study. First, the study provides an overview of the changes in the system through which the American Protestant missionaries were received in Japan during the occupation, particularly focusing on the system up to 1947, when it was first fully established by the cooperation of both U.S. Protestants and GHQ/SCAP. Next, it examines the 29 Nisei Protestant missionaries who visited Japan from 1945 to 1951 with the GHQ/SCAP approval and such features as their nationality, gender, date of birth, date of arrival, types of activities the person was involved in., education, and prior visits to Japan. These characteristics are then compared to those of other groups of missionaries who came to Japan, highlighting the distinctive traits of the Nisei missionaries. Finally, the study examines Grace Kyoko Imamoto (January 14, 1920–March 14, 2018), as a case study, and reviews her personal history in terms of her family background, living conditions, internment, Christian calling, experiences in Japan, and later life. The study explores her remarkable characteristics and outlines the future areas to be investigated.論説(Article)departmental bulletin pape
Research on Otojiro Matsuo : focusing on his time at Doshisha and his period as a chaplain in Hokkaido prison
Get PDF本論文は松尾音次郎(1864-1950)について論究したものである。松尾は兵庫県明石の生まれで、1881(明治14)年9月に同志社英学校に入学し、卒業後神学科に進みキリスト教を学ぶ。その後1892年3月から北海道にわたり、樺戸集治監にて教誨師として働く。後に松尾はイェール大学で4年間学び、経済界に進んでいくが、いわゆる「北海道バンド」の一人として重要な人物である。これまで松尾音次郎については殆ど研究されてこなかったが、同志社関係、キリスト教関係、そして監獄関係の資料を駆使し、彼の重要な時期である同志社時代と監獄教誨師時代に光を当てて明らかにする。This paper focuses on Otojiro Matsuo (1864–1950). Matsuo was born in Akashi, the Hyogo Prefecture, and entered the Doshisha English School in September 1881. After the graduation, he pursued theological studies and learned about Christianity. In March 1892, he moved to Hokkaido, where he worked as a prison chaplain at the Kabato prison. Later, Matsuo studied at Yale University for four years before entering the business world, and becoming an important figure, as one of the socalled "Hokkaido Band." While research on Otojiro Matsuo has been minimal up till now, this paper sheds light on the important periods of his life at the Doshisha and as a prison chaplain, using sources related to the Doshisha, Christianity, and prisons.研究ノート(Note)departmental bulletin pape
