Both ends of the pipe are closed. A speaker to generate sound is fixed on the end of the pipe with a reflector at the other end. Piezoelectric ceramic is used as a speaker. A sweep signal is radiated from the speaker to the water column in the pipe. The sound pressure takes the largest value at the resonant frequency. The displacement of the reflector which is inserted from another end of the pipe by a plunger, corresponds to the length of the water column. The displacement of the reflector has good correspondence to the resonant frequency of the water column. It is found from the experiment that it is possible to accurately measure underwater displacement, using this sensor.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "45956", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Suzuki, Yuji"}]}, {"nameIdentifiers": [{"nameIdentifier": "45957", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ichimiya, Ryoichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "45958", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Watanabe, Tomoyuki"}]}, {"nameIdentifiers": [{"nameIdentifier": "45959", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sakamoto, Shuichi"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本機械学会"}]}, "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/110002380897", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "日本機械学会"}, {"subitem_rights": "本文データは学会の許諾に基づくCiNiiからの複製である"}]}, "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": "AN00187463", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03875024", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "鈴木, 祐治"}], "nameIdentifiers": [{"nameIdentifier": "45952", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "一宮, 亮一"}], "nameIdentifiers": [{"nameIdentifier": "45953", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "渡邊, 友行"}], "nameIdentifiers": [{"nameIdentifier": "45954", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "坂本, 秀一"}], "nameIdentifiers": [{"nameIdentifier": "45955", "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", "download_preview_message": "", "file_order": 0, "filename": "9_0207.pdf", "filesize": [{"value": "449.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 449400.0, "url": {"label": "9_0207.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3883/files/9_0207.pdf"}, "version_id": "87282f00-dcb4-463f-a2af-5e9dadc7f4f4"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Sensor", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Measurement", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Accuracy", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Sound", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Underwater Displacement", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Resonance", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Frequency", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Speaker", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Microphone", "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": "水中における音響信号を利用した変位の精密測定（音響周波数と変位との実験）", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "水中における音響信号を利用した変位の精密測定（音響周波数と変位との実験）"}, {"subitem_title": "水中における音響信号を利用した変位の精密測定（音響周波数と変位との実験）", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/5909", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-04-08"}, "publish_date": "2008-04-08", "publish_status": "0", "recid": "3883", "relation": {}, "relation_version_is_last": true, "title": ["水中における音響信号を利用した変位の精密測定（音響周波数と変位との実験）"], "weko_shared_id": null}
