They have extremely small period derivatives and several distinct characteristics. Some of them seem to be useful as time standard. Making use of the timing stabilities, an attempt to detect the cosmic background gravitational radiations has been made elsewhere. We have been considering to make such observations using the deep space tracking telescope in Usuda. Recently we detected the pulse from PSR 1937+21,which is the most promissing object for the timing observations. We also estimate the dispersion measure which is in agreement with the previous observations. we are designing a timing equipment to be used in regular observations in the near future.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166877000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"国立天文台"},{"subitem_text_value":"国立天文台"},{"subitem_text_value":"国立天文台"},{"subitem_text_value":"国立天文台"},{"subitem_text_value":"名大空電研究所"},{"subitem_text_value":"名大空電研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"平尾, 淳一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河島, 信樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤本, 真克"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松田, 浩"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平林, 久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮地, 竹史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"御子柴, 廣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小島, 正宣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"丸山, 一夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAO, J.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWASHIMA, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"FUJIMOTO, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUDA, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRABAYASHI, S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYACHI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIKOSHIBA, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOJIMA, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MARUYAMA, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0166877.pdf","filesize":[{"value":"494.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166877.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33028/files/SA0166877.pdf"},"version_id":"bea9f343-c093-48c3-add5-949b052acf9e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ミリ秒パルサー","subitem_subject_scheme":"Other"},{"subitem_subject":"タイミング観測","subitem_subject_scheme":"Other"},{"subitem_subject":"背景重力波","subitem_subject_scheme":"Other"},{"subitem_subject":"周波数標準","subitem_subject_scheme":"Other"},{"subitem_subject":"millisecond pulsar","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"timing observation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitational background radiations","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"frequency standard","subitem_subject_language":"en","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":"ミリ秒パルサーのタイミング観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ミリ秒パルサーのタイミング観測"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33028","relation_version_is_last":true,"title":["ミリ秒パルサーのタイミング観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:17:42.040838+00:00"}
