In order to make reproducible and reliable temperature measurements based on IPTS-68 firmly established down to 13.81K and acquire some correct calibration curves, using Chromel vs Au-0.07at%Fe (KP/AuFe) thermocouples, and Pt-0.5 mol%Co(PCoRT) resistance bulbs as a first transducer, we have operated 'in-place' calibration for traceable temperature measurement by a cryogenic temperature calibrator. Various factors affording influences on the accuracy of measurement have been investigated, e.g., the suitability of inserted length for sensor, connecting method of compensating lead wires, the structure of fixed points, the stability of amplifiers, the properties of recording instruments, at every experiment. Lately we have succeeded in establishing the measurement system with the allowance less than 0.5K.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166606000","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"青柳, 鐘一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"霜田, 正隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"加勇田, 清勇"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"斉藤, 猛男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山谷, 寿夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岩間, 彬"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AOYAGI, Shoichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIMODA, Masataka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAYUTA, Seiyu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAITO, Takeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMAYA, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IWAMA, Akira","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":"SA0166606.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166606.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32837/files/SA0166606.pdf"},"version_id":"37118f67-b156-4f93-9746-766946954f9d"}]},"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":"LH_2/LOX エンジン開発における極低温温度計測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LH_2/LOX エンジン開発における極低温温度計測"}]},"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":"32837","relation_version_is_last":true,"title":["LH_2/LOX エンジン開発における極低温温度計測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:22:45.090335+00:00"}
