The barrel length was 0.9m. The tests revealed that the clearance between the jacket and the barrel (which together made up an Archimedean pump) should be a little wider for drilling in a liquidfilled hole than in a dry hole. With the clearance of 7.4mm, the pump could transport ice chips to the storage space between the booster and the sweeper, where the booster compacted chips by squeezing a large portion of the liquid through the sweeper which was permeable to liquid. The porosity of compacted chips could be as low as 35%.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido University/Institute of Low Temperature Science, Hokkaido University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1986-12-01"}],"displaytype":"detail","filename":"KJ00000012633.pdf","filesize":[{"value":"780.7 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012633","url":"https://nipr.repo.nii.ac.jp/record/2080/files/KJ00000012633.pdf"},"version_id":"f2187aa2-ae9a-41c5-8f5d-beee6c395ceb"}]},"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":"Development of an ice core drill for liquid-filled holes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of an ice core drill for liquid-filled holes","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["399"],"pubdate":{"attribute_name":"公開日","attribute_value":"1986-12-01"},"publish_date":"1986-12-01","publish_status":"0","recid":"2080","relation_version_is_last":true,"title":["Development of an ice core drill for liquid-filled holes"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:44:40.694172+00:00"}
