Information of surface vibration velocity on the piezoelectric transducer and sample are effectively used. Rectangular pulse having the time width of resonance period of transducer was adopted to cancel the mechanical ringing. Exciting efficiency of transducer was improved by lager than 20 dB compared to our previous study. Imaging for the thin brass plate with etched \"3\" character is clearly imaged using time difference mode. As the result of experiment, possibilities as a tool for evaluating the thin plate like solid sample around several tens of μm such as electronic devices are revealed.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人 日本画像学会"}]},"item_10001_relation_12":{"attribute_name":"NII論文ID NAID","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"130007432995","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11370/isj.57.422","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA1137305X","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-4425","subitem_source_identifier_type":"ISSN"}]},"item_10001_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"秋田大学　理工学研究科"}]},"item_10001_version_type_20":{"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":"今野, 和彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IMANO, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-11-07"}],"displaytype":"detail","filename":"572-4-1.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"riA_2019_4","url":"https://air.repo.nii.ac.jp/record/3816/files/572-4-1.pdf"},"version_id":"3732af97-8013-4b6f-865d-dfc15997903a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"振動速度","subitem_subject_scheme":"Other"},{"subitem_subject":"超音波","subitem_subject_scheme":"Other"},{"subitem_subject":"圧電振動子","subitem_subject_scheme":"Other"},{"subitem_subject":"振動速度差","subitem_subject_scheme":"Other"},{"subitem_subject":"伝搬時間差","subitem_subject_scheme":"Other"},{"subitem_subject":"薄板状試料","subitem_subject_scheme":"Other"},{"subitem_subject":"Vibration velocity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ultrasonic wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Piezoelectric transducer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Velocity difference","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Time difference","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Thin sample","subitem_subject_language":"en","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":"振動速度情報を用いた薄い板状試料の超音波イメージング","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"振動速度情報を用いた薄い板状試料の超音波イメージング"}]},"item_type_id":"10001","owner":"18","path":["630"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-11-07"},"publish_date":"2019-11-07","publish_status":"0","recid":"3816","relation_version_is_last":true,"title":["振動速度情報を用いた薄い板状試料の超音波イメージング"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-25T11:15:03.416727+00:00"}
