Its applications have been developed in fuzzy and adaptive control method used in washing machines. To date, technologies of computers with high speed and ADC (Analog Digital Converter) with wide dynamic range have been advanced. Therefore, the digital feedback control method has enough potential to be employed to a servo-type seismometer instead of its analog feedback circuit. However, to use the digital feedback control, the problems to be overcome still remain. Those are the dynamic range and the data acquisition speed of ADC/DAC (Digital Analog Converter). This paper proposes an idea to obtain ADC/DAC with wide dynamic range and high-speed data acquisition. In a case of DAC, we use two devices for one data output. One is used to convert upper-half bits of the data and the other is for lower-half bits. ADC also has the same situation. By the above-mentioned method using the two devices with smaller bit-width, the higher data-acquisition speed and the data with a wider dynamic range will be obtained. Now, we will try to develop a PID digital feedback control circuit using the method. The method is patent pending.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜論説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71968","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OTAKE, Yuji"}]},{"nameIdentifiers":[{"nameIdentifier":"71969","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TSUJI, Nobuyuki"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032245","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1144042X","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute，University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学地震研究所技術開発室"},{"subitem_text_value":"ツジ電子株式会社"},{"subitem_text_value":"Laboratory for Technical Service and Development, Earthquake Research Institute, University of Tokyo"},{"subitem_text_value":"TSUJI Electronics Co., Ltd"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大竹, 雄次"}],"nameIdentifiers":[{"nameIdentifier":"71966","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻, 信行"}],"nameIdentifiers":[{"nameIdentifier":"71967","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":"2017-06-12"}],"displaytype":"detail","filename":"05_023-028.pdf","filesize":[{"value":"1023KB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"05_023-028.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32254/files/05_023-028.pdf"},"version_id":"9655d45f-7b65-487e-946e-5b0a210ab662"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"control","subitem_subject_scheme":"Other"},{"subitem_subject":"PID","subitem_subject_scheme":"Other"},{"subitem_subject":"seismometer","subitem_subject_scheme":"Other"},{"subitem_subject":"servo control","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ディジタルPIDフィードバックコントローラーの高速・高ダイナミックレンジ化の提案（地震計への応用）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ディジタルPIDフィードバックコントローラーの高速・高ダイナミックレンジ化の提案（地震計への応用）","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4489","4490"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32254","relation_version_is_last":true,"title":["ディジタルPIDフィードバックコントローラーの高速・高ダイナミックレンジ化の提案（地震計への応用）"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:05.345862+00:00"}
