Therefore, recent years this amplifier has increasingly come into practical use for amplifying under a few cycles of frequency, i. e. dc. A magnetic amplifier, however, has not yet come to be put to practical use for audio frequency. It is the purpose of this paper to analyse the magnetic amplifier that amplifies audio frequencies. And the equations of output power, input power and amplification are introduced. The results obtained by these equations almost agree with experimental tests made for magnetic amplifier that amplifies a single frequency, 50 cycles.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 8: 53-68 (1959)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","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":"青木,  頼元","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering08-06.pdf","filesize":[{"value":"601.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering08-06.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13161/files/Engineering08-06.pdf"},"version_id":"9d23c5a4-adb8-46ff-aae9-b06b670bfbef"}]},"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":"低周波磁気増幅器","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低周波磁気増幅器","subitem_title_language":"ja"},{"subitem_title":"Magnetic Amplifiers for Audio Frequencies","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1299"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-02-15"},"publish_date":"2011-02-15","publish_status":"0","recid":"13161","relation_version_is_last":true,"title":["低周波磁気増幅器"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T04:50:30.214573+00:00"}
