In the use of this type of slip sensor, some difficulty was found in adjusting and resetting the voltage corresponding to the zero slippage, depending on the running gear prior to the operation. A different type of slip sensor was therefore designed and constructed to remedy this disadvantage. The photo-electric type pulse generator was used to detect the rotational speed of both front and rear wheels through the mechanical amplification by use of gears to obtain the required numbers of pulses per unit rotation of the wheel. The number of pulses generated from the wheels was converted to the frequency and then to the voltage. This output voltage was compared to the set voltage which corresponds to the set slippage. In turn this is properly determined from the relationship between the slippage and the pulling froce expressing the different shape due to the soil condition and running device. The difference between the output voltage and set voltage was amlified. Then the relay connected to the hydraulic directional valve to control lifting and lowering the implement mounted on the three point linkage moved on off, depending on the voltage difference. The slippage calculated from the difference indicated through the monitoring device mounted on the platform located in front of operator's seat. This monitoring device worked quite satisfactorily to help the operator in knowing how much draft force was acting on the implement through the indicated value of the slippage. The field test was done to validate the accurate response and action of the implement under slip draft control in two kinds of fields, sandy and paddy, after harvesting of rice. Through the satisfactory result of the field experiments, it was observed that this type of slip draft control system described here would be possible to apply to a commercial tractor without much modification and improvements. No problems of cost, accuracy or durability for practical use were found.","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学農学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0462-4408","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00234337","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"614","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Slip meter for direct indication and its application to draft control"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"attribute_name":"著者版フラグ","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":"伊藤, 信孝","creatorNameLang":"ja"},{"creatorName":"Ito, Nobutaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"竹内, 章博","creatorNameLang":"ja"},{"creatorName":"Takeuchi, Akihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"馬淵, 久志","creatorNameLang":"ja"},{"creatorName":"Mabuchi, Hisashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本, 昭裕","creatorNameLang":"ja"},{"creatorName":"Yamamoto, Akihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"AN002343370006111.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN002343370006111.pdf","url":"https://mie-u.repo.nii.ac.jp/record/6292/files/AN002343370006111.pdf"},"version_id":"7b18a937-c93b-4321-91ff-fde9f836ba03"}]},"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":"直視式すべり率計とそのけん引負荷制御への適用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"直視式すべり率計とそのけん引負荷制御への適用","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["499"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-03-29"},"publish_date":"2007-03-29","publish_status":"0","recid":"6292","relation_version_is_last":true,"title":["直視式すべり率計とそのけん引負荷制御への適用"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-13T04:07:28.839134+00:00"}
