The spindles could be driven very silently at high speed without vibration, and have already been used in practice for over two years. With these spindles, the efficiency of drilling small holes in pillar-plates has increased by 200 %. Experimental investigations on the relations between drilling efficiency and rotating or feeding speed were carried out in the laboratory, and it is concluded that in order to drill. Small precise holes (0.3mm-1.5mm) efficiently, drills must be chucked with eccentricity less than about 0.005mm, and must be driven with high speed over 10,000rpm.", "subitem_description_type": "Other"}]}, "item_9_description_32": {"attribute_name": "資料番号", "attribute_value_mlt": [{"subitem_description": "資料番号: SA1511444000", "subitem_description_type": "Other"}]}, "item_9_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "東京大学理工学研究所"}]}, "item_9_source_id_21": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0371-6090", "subitem_source_identifier_type": "ISSN"}]}, "item_9_source_id_24": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00162611", "subitem_source_identifier_type": "NCID"}]}, "item_9_text_34": {"attribute_name": "メタデータ提供者", "attribute_value_mlt": [{"subitem_text_value": "メタデータ提供者: ISASNII"}]}, "item_9_text_35": {"attribute_name": "JAXAカテゴリ", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ: 宇宙科学研究所"}]}, "item_9_text_43": {"attribute_name": "DSpaceコレクション番号", "attribute_value_mlt": [{"subitem_text_value": "DSpaceコレクション番号: 6"}]}, "item_9_text_6": {"attribute_name": "著者所属", "attribute_value_mlt": [{"subitem_text_value": "東京大學理工學研究所"}, {"subitem_text_value": "東京大學理工學研究所"}]}, "item_9_text_7": {"attribute_name": "著者所属（英）", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "The Institute of Science and Technology, University of Tokyo"}, {"subitem_text_language": "en", "subitem_text_value": "The Institute of Science and Technology, University of Tokyo"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "安川, 太郎"}], "nameIdentifiers": [{"nameIdentifier": "418929", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "關, 悟"}], "nameIdentifiers": [{"nameIdentifier": "418930", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yasukawa, Taro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "418931", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Seki, Satoru", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "418932", "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": "2020-01-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "SA1511444.pdf", "filesize": [{"value": "1.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1600000.0, "url": {"label": "SA1511444.pdf", "url": "https://jaxa.repo.nii.ac.jp/record/34201/files/SA1511444.pdf"}, "version_id": "24089106-1748-4a27-bdaa-8990b9d95196"}]}, "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": "小孔の加工能率の向上について : 精密ボール盤主軸の試作(應用力學)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "小孔の加工能率の向上について : 精密ボール盤主軸の試作(應用力學)"}]}, "item_type_id": "9", "owner": "1", "path": ["1890", "1908"], "permalink_uri": "https://jaxa.repo.nii.ac.jp/records/34201", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-03-26"}, "publish_date": "2015-03-26", "publish_status": "0", "recid": "34201", "relation": {}, "relation_version_is_last": true, "title": ["小孔の加工能率の向上について : 精密ボール盤主軸の試作(應用力學)"], "weko_shared_id": -1}
