The seismo-counter consists of a short-period pick-up, amplifiers, squaring circuits and a series of flip-flop circuits, and drives an electro-magnetic counter only when it receives a seismic signal exceeding both the pre-set level of amplitude and the pre-set pulse rate. In this way, it counts the number of seismic events accurately being unaffected by simple pulse signals as often origined from artificial noise sources. The authors reconstructed <three four>sets of the seismo-counters and operated them successfully to register the daily frequency of earthquake occurrence at several localities in and around the Matsushiro seismic area.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"130600","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shibano, Mutsuro"}]},{"nameIdentifiers":[{"nameIdentifier":"130601","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sasaki, Koichi"}]},{"nameIdentifiers":[{"nameIdentifier":"130602","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsumoto, Shigeo"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033442","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":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"柴野, 睦郎"}],"nameIdentifiers":[{"nameIdentifier":"130597","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐々木, 幸一"}],"nameIdentifiers":[{"nameIdentifier":"130598","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本, 滋夫"}],"nameIdentifiers":[{"nameIdentifier":"130599","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":"ji0463012.pdf","filesize":[{"value":"631.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0463012.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33442/files/ji0463012.pdf"},"version_id":"6783f8e8-c859-46df-b15a-fd5d39ff4e9f"}]},"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":"32.地震回数計 : その試作と観測結果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"32.地震回数計 : その試作と観測結果","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4921","4922"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33442","relation_version_is_last":true,"title":["32.地震回数計 : その試作と観測結果"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:37:48.590375+00:00"}
