Copper and stainless steel spheres in which Pt/Pt-13% Rh thermocouple was embedded were used as specimens. Heating efficiency was evaluated by a tangent of temperature vs. time curve of the specimen at the initial stage of heating. Experiments covered three types of the coil, namely, cylindrical, conical with 2/10 tapered, and 4/10 tapered coil. Experimental results are summarized as follows : 1) Relationships between heating efficiency vs. coil current indicate that the heating efficiency is proportional to the 2.3～3.0 power of the coil current for copper specimen and is proportional to the 2.0～2.2 power of the coil current for stainless steel specimen. 2) For stainless steel specimen, the heating efficiency is proportional to the 0.78 power of the frequency of coil current. 3) Above results do not agree with the theoretical predictions. The discrepancies presumably depend on the non-uniformity of the magnetic field through the coil and consequently depend on the local heating of the specimen. 4) Effect of the coil shape is not remarkable under the experimental conditions. 5) By assuming the average magnetic field in the coil, the theoretical calculations agree with the experimental results within the error of ±50%.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"397427 bytes","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"123191","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIRAISHI, Yutaka"}]},{"nameIdentifiers":[{"nameIdentifier":"123192","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAITO, Tunezo"}]}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北大學選鉱製錬研究所"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0040876X","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00168425","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"白石, 裕"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"斎藤, 恒三"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000658493.pdf","filesize":[{"value":"397.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000658493.pdf","url":"https://tohoku.repo.nii.ac.jp/record/50422/files/KJ00000658493.pdf"},"version_id":"8d84c95b-9d62-424f-94e4-64795c3c9448"}]},"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":"<報文>電磁浮揚の特性に関する基礎的研究(その2) : 加熱力について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<報文>電磁浮揚の特性に関する基礎的研究(その2) : 加熱力について"}]},"item_type_id":"4","owner":"3","path":["292"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"50422","relation_version_is_last":true,"title":["<報文>電磁浮揚の特性に関する基礎的研究(その2) : 加熱力について"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T18:18:28.046567+00:00"}
