Despite the machine type, centrifugal(CT) or two-chamber pressure(PR)machine, jet flow and F type filling were observed in the occlusal area. The flow pattern in the axial area, however, was controlled by the main body force of each casting machine; it was the B type for PR and the F type for CT. Major factors related to internal defects were sprue diameter for PR and sprue-attachment position and angle for CT.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39944","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Kouichi"}]},{"nameIdentifiers":[{"nameIdentifier":"39945","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okawa, Seigo"}]},{"nameIdentifiers":[{"nameIdentifier":"39946","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kanatani, Mitsugu"}]},{"nameIdentifiers":[{"nameIdentifier":"39947","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakano, Syuji"}]},{"nameIdentifiers":[{"nameIdentifier":"39948","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Miyakawa, Osamu"}]},{"nameIdentifiers":[{"nameIdentifier":"39949","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kobayashi, Masayoshi"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本歯科理工学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002992612","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本歯科理工学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00127279","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02865858","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡辺, 孝一"}],"nameIdentifiers":[{"nameIdentifier":"39938","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大川, 成剛"}],"nameIdentifiers":[{"nameIdentifier":"39939","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金谷, 貢"}],"nameIdentifiers":[{"nameIdentifier":"39940","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中野, 周二"}],"nameIdentifiers":[{"nameIdentifier":"39941","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮川, 修"}],"nameIdentifiers":[{"nameIdentifier":"39942","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 正義"}],"nameIdentifiers":[{"nameIdentifier":"39943","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":"2019-07-30"}],"displaytype":"detail","filename":"110002992612.pdf","filesize":[{"value":"835.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110002992612.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2932/files/110002992612.pdf"},"version_id":"4679950e-bbe4-4dbd-8b04-4ce95730aab3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"チタン","subitem_subject_scheme":"Other"},{"subitem_subject":"湯流れ","subitem_subject_scheme":"Other"},{"subitem_subject":"鋳造欠陥","subitem_subject_scheme":"Other"},{"subitem_subject":"加圧鋳造","subitem_subject_scheme":"Other"},{"subitem_subject":"遠心鋳造","subitem_subject_scheme":"Other"},{"subitem_subject":"Titanium","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow of molten metal","subitem_subject_scheme":"Other"},{"subitem_subject":"Casting defect","subitem_subject_scheme":"Other"},{"subitem_subject":"Pressure casting","subitem_subject_scheme":"Other"},{"subitem_subject":"Centrifugal casting","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"U字型キャビティ内のチタン湯流れ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"U字型キャビティ内のチタン湯流れ"},{"subitem_title":"U字型キャビティ内のチタン湯流れ","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","476"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-04-05"},"publish_date":"2012-04-05","publish_status":"0","recid":"2932","relation_version_is_last":true,"title":["U字型キャビティ内のチタン湯流れ"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:08.258092+00:00"}
