The numerous kinds of process variables in the systems, such as pressure, different pressure, flow rate and level etc. , primarily convert angles or displacements, then they are measured by electrical quantities with the various methods. The mutual induction angular displacement transducer performs the conversion from amguar displacement to electrical quantities, which consists of the semi-toroidal or circular shaped core and the semi-toroidal solenoid coil with primary and secondary windings. The primary windings are connected series and the two secondary windings are connected counter-series each other as well as two sectional type linear differential transformer. When any angular displacement is given to the core located in the semitoroidal solenoid coil, it induces the secondary output voltage proportionl to the angular displacement. Many angular displacement transducers, such as a hall-generator, heat conduction, resistance (potentiometer type), photo-cell, code plate and electromagnetic induction, have been developed till quite recently from the various countries. The outline of their principle of operations and the characteristics are introduced in the second chapter. In the third chapter, analysis of the conversion characteristics made by using modeling methods of flux distribution on the core of the mutual induction angular displacement transducer and its experimental results are described. The shapes of the flux distributions on the core is assumed as rectangular, parabolic and sinusoidal. The limitation on the linear range of the output voltage and on the constancy of the primary inductance are theoretically analyzed by the above mentioned flux distribution, and satisfactory coincidence is obtained with the experimental results. Improvement of the linearity of the output voltage by the magnetic field compensation and the asymmetrical winding methods based on the modeling analysis are also discussed in this chapter. In the fourth chapter, the theoretical equation of secondary output voltage on the mutual induction angular displacement transducer is derived by the quantity of the coupling factor which depends on angular displacement. Frequency characteristics of the transducer, and comparison of the different transducers, which have different winding constructions and core materials, are checked in this chapter. The transducer is able to measure electrically the mechanical angular displacements from 0 to 50 degrees with the linearity ± 1.0 per cent at the exciting frequency 1 kilocycles. 1 minute (=0.0167 degrees) of angular displacement is detectable in the vicinity of electrical zero point characteristics by DC output signal.","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":"信州大学工学部紀要 19: 71-116 (1965)","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_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","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":"山田,  一","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":"Engineering19-07.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering19-07.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13102/files/Engineering19-07.pdf"},"version_id":"21a47f25-849b-4c18-b487-c4be865d5298"}]},"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":"相互誘導形角度トランスジューサの変換理論","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"相互誘導形角度トランスジューサの変換理論","subitem_title_language":"ja"},{"subitem_title":"Conversion Theory on Mutual Induction Angular Displacement Transducer","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1288"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-30"},"publish_date":"2009-03-30","publish_status":"0","recid":"13102","relation_version_is_last":true,"title":["相互誘導形角度トランスジューサの変換理論"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T04:47:15.561776+00:00"}
