A gyroscopic power generator which generates high speed rotation of permanent magnets using vibrations of human body in daily life is developed. A prototype generator and its fundamental characteristics based on the analysis of the rotor dynamics are presented. Various ways are tried in order to gain higher output power of the generator. High level potential of the generator and its availability for a mobile phone are verified. However, a gyroscopic power generator is difficult to maintain the rotation. Also, an initial velocity is needed for the rotor because it is a non-linear system. So we developed several ways to activate the rotor by external power automatically. The fact that the rotor can be accelerated to sufficient speed for stable rotation is verified.","subitem_description_type":"Abstract"}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"master"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"新領域創成科学研究科人間環境学専攻"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"修創域第3496号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院新領域創成科学研究科環境学研究系人間環境学専攻"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"笠原, 学"}],"nameIdentifiers":[{"nameIdentifier":"8985","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":"2017-05-31"}],"displaytype":"detail","filename":"K-02260-a.pdf","filesize":[{"value":"680.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨(summary)","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/3851/files/K-02260-a.pdf"},"version_id":"7fade4cb-6efc-4dd4-a7c2-f9157f143001"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Gyroscopic","subitem_subject_scheme":"Other"},{"subitem_subject":"Vibration","subitem_subject_scheme":"Other"},{"subitem_subject":"Generator","subitem_subject_scheme":"Other"},{"subitem_subject":"Prototype","subitem_subject_scheme":"Other"},{"subitem_subject":"Self activation","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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"ジャイロ型発電機高出力化の研究（要旨）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ジャイロ型発電機高出力化の研究（要旨）"}]},"item_type_id":"7","owner":"1","path":["234","256"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-12"},"publish_date":"2012-10-12","publish_status":"0","recid":"3851","relation_version_is_last":true,"title":["ジャイロ型発電機高出力化の研究（要旨）"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:45:32.676867+00:00"}
