The first generation (CA-3672) was completed in September 1998. Its sensitivity was low and its specification was not enough for precise observation of the ground motion, and we are improving it since February 2000. During the process, we carried out several observations to check their specifications and to compare with a water-tube tiltmeter that was already put to practical use in many observations. As a result, we have recently completed the new model CA-3917(fourth-generation). The measurement sensitivity of this tiltmeter using a XY magnetic detector is higher than 10-8 radian, and zero point drift is less than 10-8 radian/day. These values are enough to meet the practical requirement for measuring the crust deformation accompanied with volcanic activity. In this paper, we report the outline of the developing process of the tiltmeters.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜論説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71829","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKEDA, Toyotaro"}]},{"nameIdentifiers":[{"nameIdentifier":"71830","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Hidefumi"}]},{"nameIdentifiers":[{"nameIdentifier":"71831","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOYAMA, Etsuro"}]},{"nameIdentifiers":[{"nameIdentifier":"71832","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HIRATA, Yasuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"71833","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Shigeru"}]},{"nameIdentifiers":[{"nameIdentifier":"71834","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ONISHI, Masaomi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032213","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11602838","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute，University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学地震研究所火山噴火予知研究推進センター"},{"subitem_text_value":"火山噴火予知研究推進センター浅間火山観測所"},{"subitem_text_value":"地震地殻変動観測センター"},{"subitem_text_value":"地震地殻変動観測センター富士川地殻変動観測所"},{"subitem_text_value":"株式会社マコメ研究所"},{"subitem_text_value":"Volcano Research Center,"},{"subitem_text_value":"Asama Volcano Observatory, Volcano Research Center"},{"subitem_text_value":"Earthquake Observation Center"},{"subitem_text_value":"Fujigawa Observatory, Earthquake Observation Center, Earthquake Research Institute, University of Tokyo"},{"subitem_text_value":"Macome Corporation"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹田, 豊太郎"}],"nameIdentifiers":[{"nameIdentifier":"71823","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡辺, 秀文"}],"nameIdentifiers":[{"nameIdentifier":"71824","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小山, 悦郎"}],"nameIdentifiers":[{"nameIdentifier":"71825","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平田, 安廣"}],"nameIdentifiers":[{"nameIdentifier":"71826","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡辺, 茂"}],"nameIdentifiers":[{"nameIdentifier":"71827","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大西, 正臣"}],"nameIdentifiers":[{"nameIdentifier":"71828","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"08_016-025.pdf","filesize":[{"value":"4.2MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"08_016-025.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32222/files/08_016-025.pdf"},"version_id":"5f2826d5-e594-4dd8-bc91-858a121e147b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Tiltmeter","subitem_subject_scheme":"Other"},{"subitem_subject":"XY Magnetic Detector","subitem_subject_scheme":"Other"},{"subitem_subject":"High Sensitivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Magnetometer","subitem_subject_scheme":"Other"},{"subitem_subject":"Borehole","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"XY磁気センサーを用いた傾斜計の改良について（序報）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"XY磁気センサーを用いた傾斜計の改良について（序報）","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4483","4484"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32222","relation_version_is_last":true,"title":["XY磁気センサーを用いた傾斜計の改良について（序報）"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:07:01.936560+00:00"}
