In this apparatus, a barium titanate transducer is coupled to the one end of the wire, and the transducer emitts the longitudinal waves into the wire. Then the waves travel along the wire toward the other end of it and these waves partly reflected according to the conditions of the termination. When the waves have a sinusoidal waveform of certain frequency, they form ultrasonic standing waves along the wire. From the measurements of these standing waves along the wire, we can obtain the following important quantities in transmission characteristics of the wire or of the load impedance. (1) The half wave-length is obtained from the distance between the successive minima in the standing wave pattern. (2) When the diameter of the wire and the density of the wire material is known, the Young's modulus of the materials and the characteristic acoustic impedance of it will readily be calculated. (3) From the standing wave ratio, the reflection coefficient of the load terminating the wire will be calculated. (4) And, at the same time, if the distance from the terminating point to the point where the velocity indicates a minimum amplitude is known, the value of the mechanical impedance of the load will be calculated by the ordinary impedance chart. The principle of these methods, instrumental consideration, and some observed result. are discussed.","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 10: 230-250 (1960)","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":"安田,  力","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":"Engineering10-12.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering10-12.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13146/files/Engineering10-12.pdf"},"version_id":"ec759f39-68b8-43d3-a95f-667d0ff3ea56"}]},"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":"超音波定在波測定装置","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超音波定在波測定装置","subitem_title_language":"ja"},{"subitem_title":"Ultrasonic Standing Wave Detector","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1297"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-01-05"},"publish_date":"2011-01-05","publish_status":"0","recid":"13146","relation_version_is_last":true,"title":["超音波定在波測定装置"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T04:50:53.311115+00:00"}
