Recently the treatment of mine drainage, especially acid mine drainage (AMD) is attracting a lot of attention, including the passive treatment that is a cost-effective and energy efficient process. In such a process, the natural geochemical reaction, gravitational flow, bacteria metabolism, etc, are utilized for the active treatment, enabling continuous addition of chemical reagents and maintenance of mechanical facilities, and so on. For a long time, the development of the passive treatment was mainly carried out in North America and Europa, thus, much useful knowledge is cultivated and many experimental and actual sites are operated in these area. In this paper, the useful knowledge, information and instances related to the passive treatment are reviewed. The performance of sulfate reducing bacteria (SRB) is very important for the treatment of the mine drainage from non-ferrous mine sites. Thus, the matters related with SRB, that is, the reaction, the reactor and the operation are also described in detail.

In this paper, construction logic of a man/machine safety work system is presented. Especially in a system where the human and machine cooperatively work on the time axis, safety assurance requires the human and machine to maintain different positions or states. A control of this positional relationship or state change is defined as block section control. In Chapter 3, the safety of the platform door system composed of train doors and platform doors is discussed. These systems are characteristic in that it has two or more safe areas and that its hazardous area change to safety area. The concept of the man/machine safety work system is applied to the station platform door system, and the conditions for assuring the safety of the control the station platform door system are derived.

In 1903, Hirata was sent to go to England for three years as a student of the Department of Education in order to study “English and a Method of Teaching English”.On the 21st of Fubruary, he left Yokohama for England, taking with him words of encouragement and farewell gifts presented by his teachers and his students. He arrived in London at the end of April. While staying in Japanese Cosulate, he saw the sights of London and sometimes visited the museums. He also frequented the theaters with his friends to see the plays such as “Much Ado About Nothing, ” “Dante, ” “Sapho, ” “Tristram and Iseult”.He met Mr. Osman Edwards again whom he had maintained a close friendship with in Japan five years before. When he was in Japan to study Japanese plays and actors, he was accompanied by Hirata to the plays (Noh and Kabuki) and sometimes translated his essays of “On Japanese Plays” into Japanese so that Edwards could contribute to Japanese magazines.This time, Edwards welcomed Hirata warmly, showing him around London to see the art museums and theaters. He often took Hirata to the Playgoer's Club.Hirata also visited Hogetu Shimamura. Shimamura had been staying in England for a year as a student from Waseda University and began a friendship with him in London. Before long Hirata decided to go and study at Oxford University and moved there. Hirata's association with Hogetu in Oxford continued until he left for Germany at the end of July in 1904. The state of their association can be seen in “Diary from March 8, 1902” written by Hogetu himself. Hirata associated with Japanese students in Oxford with an introduction from Hogetu. In October he began to present himself at the lectures of Dr. H. Sweet, Prof. Walter Raleigh, Prof. A.S. Napier, Lecturer E.de Selincourt at Merton, Magdalen, Balliol College and so forth.

1 0 0 0 OA 草津白根山火口湖湯釜の化学組成経年変化から推定するマグマ脱ガスモデル

草津白根山の火口湖湯釜の化学組成経年変化からマグマの脱ガスモデルを提案する.1966年から1981年までは,マグマを取り囲むように形成された熱水二次鉱物からなるシーリングゾーンが成長し,マグマから放出されるSやClの流量は漸減しつつあった.1982,83年の噴火の際は,シーリングゾーンが破壊し,一部は熱水に再溶解し,火口湖に供給され,湖水の硫酸イオン濃度が上昇した.1990年には破壊されたシーリングゾーンを貫いて地下水が冷却しつつあるマグマに浸入し,マグマに残存していたClを熱水に抽出した.このためにClに富んだ熱水が発生し,火口湖に供給され,塩化物イオン濃度の上昇を引き起こした.
