Hereupon, of the three types of lens shutter (namely COMPER, PRONTOR and VARIO type), I have investigated the exposure time, exposure efficiency, exposure fluctuation and properties and velocity when it is opened and shut. From my experimental results, I have pointed out the fault of their inechanism and have suggested a new correct mechanism of the lens shutter. Moreover, this experiment has been done as part of study of im-provement of the lens shutter.","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":"信州大学工学部研究報告 2: 21-28(1953)","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_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121239","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":"市川,  誠","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":"Engineering02-03.pdf","filesize":[{"value":"386.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering02-03.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13220/files/Engineering02-03.pdf"},"version_id":"6c6b6743-da4a-483c-a42c-e5d27da913f3"}]},"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":"Lens Shutter の性能に就いて","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Lens Shutter の性能に就いて","subitem_title_language":"ja"},{"subitem_title":"ON THE PROPERTIES OF LENS SHUTTER","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1305"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-02-15"},"publish_date":"2011-02-15","publish_status":"0","recid":"13220","relation_version_is_last":true,"title":["Lens Shutter の性能に就いて"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T02:56:15.931322+00:00"}
