The purpose of ASR-80R system is to gain origin times of airgun or explosion for seismic reflection/refraction study using an ocean bottom seismometer. The system using a microprocessor can save approximately 340 of airgun firing time within ±2 miliseconds precision. The maximum recording time is 3 hours for 30 seconds airgun firing interval time by digital form. On shipboard, the firing times are stored in IC memory, and then these are loaded on an audio cassette tape by 1,200 Baud-rate. The loading time is very short: approximately 30 seconds. The data obtained on shipboard using the above system are transferred from IC memory of the ASR-80R to mini-floppy disk in the IDS-8000Z microcomputer system at a land-based laboratory.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128821","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saitoh, Makoto"}]},{"nameIdentifiers":[{"nameIdentifier":"128822","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kasahara, Junzo"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033039","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":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"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":"東海大学海洋学部"},{"subitem_text_value":"東京大学地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"斉藤, 誠"}],"nameIdentifiers":[{"nameIdentifier":"128819","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"笠原, 順三"}],"nameIdentifiers":[{"nameIdentifier":"128820","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0561009.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0561009.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33039/files/ji0561009.pdf"},"version_id":"15115b2d-bdd9-4091-b909-8d6bb4f06f21"}]},"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":"マイクロプロセッサーを使用したエアガン発音時刻収集システム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マイクロプロセッサーを使用したエアガン発音時刻収集システム","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4825","4826"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33039","relation_version_is_last":true,"title":["マイクロプロセッサーを使用したエアガン発音時刻収集システム"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:40.851086+00:00"}
