After connecting a terminal for the frequency output, a sinusoidal AC signal with a peak-to-peak voltage of 2V could be detected. The output frequency was approximately 8.4 MHz and its precision was 0.0001 Hz. Its long-term stability and temperature dependency were estimated to be better than 10－11/day and 10－11/K, respectively, which are smaller than the values listed in the datasheet. Although the warm-up time was about 20% longer than the listed value, the peak power consumption was about 33% smaller. 　　The high level of precision and stability would allow the device to be used to, for example, the frequency counter circuit of a proton precession magnetometer for measuring the geomagnetic total intensity.","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":"71469","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OGAWA, Tsutomu"}]},{"nameIdentifiers":[{"nameIdentifier":"71470","nameIdentifierScheme":"WEKO"}],"names":[{"name":"URANO, Sachiko"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032147","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観測開発基盤センター"},{"subitem_text_value":"東京大学地震研究所技術部技術開発室（開発系）"},{"subitem_text_value":"Center for Geophysical Observation and Instrumentation, Earthquake Research Institute, University of Tokyo"},{"subitem_text_value":"Laboratory for Technical Service and Development (Development Group), Technical Division, Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小河, 勉"}],"nameIdentifiers":[{"nameIdentifier":"71467","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浦野, 幸子"}],"nameIdentifiers":[{"nameIdentifier":"71468","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":"19_007-012.pdf","filesize":[{"value":"1.2MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19_007-012.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32156/files/19_007-012.pdf"},"version_id":"24258461-938a-4e63-bb50-7aa7f516fef2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Rubidium Atomic Frequency Standard","subitem_subject_scheme":"Other"},{"subitem_subject":"Frequency","subitem_subject_scheme":"Other"},{"subitem_subject":"Long-term Stability","subitem_subject_scheme":"Other"},{"subitem_subject":"Temperature Sensitivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Warm-up Time","subitem_subject_scheme":"Other"},{"subitem_subject":"Consumption Power","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":"中古ルビジウム発振器の性能評価試験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中古ルビジウム発振器の性能評価試験","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4461","4462"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32156","relation_version_is_last":true,"title":["中古ルビジウム発振器の性能評価試験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:11:09.325634+00:00"}
