The authors, therefore, had studied a measuring device for that purpose. The principle of this device is based on the fact that as air is confined in a enclosure of constant temperature and volume, the head loss between two points can be determined by comparing the absolute pressure of the each point with the confined air pressure. Such device had been used to measure the head loss at some mines and tunnels, and fine results had been obtained. But difficulty exists in manipulation of this device. So the authors improved some parts of the device. Present paper describs the principle of this device and results of its improvements.","subitem_description_type":"Abstract"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TD00004080","subitem_relation_type_select":"NCID"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"4298373","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"DANNO, Masaru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKIMOTO, Masaki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-08-04"}],"displaytype":"detail","filename":"AN00215401-027-02-001.pdf","filesize":[{"value":"480.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00215401-027-02-001.pdf","url":"https://u-fukui.repo.nii.ac.jp/record/21713/files/AN00215401-027-02-001.pdf"},"version_id":"60183a77-cc0c-4176-b4c3-af783d06507b"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Study on the Measurement of Tunnels Head Loss","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Study on the Measurement of Tunnels Head Loss"}]},"item_type_id":"10002","owner":"1","path":["2265"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-11-02"},"publish_date":"2011-11-02","publish_status":"0","recid":"21713","relation_version_is_last":true,"title":["Study on the Measurement of Tunnels Head Loss"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T13:14:23.922451+00:00"}
