Main features are : storage of a large number of events, namely, 750 events on 4 channels, 2-minutes each and 100 Hz sampling rate ; including ADPCM (Adaptive Differential Pulse Code Modulation) speech synthesis ; a long (4 minutes max. on 4 channels) buffer size for the pre-event-delay using two 8 bit CMOS micro-processors. Events are identified by the event triggering algorithm. 100 Hz or 200 Hz samplings are used. On collecting data, the length of one sampling is compressed from 12 bit to 4 bit by ADPCM-IC and the compressed data are stored on digital tape. Records on the tape are synthesized by ADPCM-IC, or soft-ware on a mini-computer. By use of the ADPCM method, the total amount of data that can be put on a tape is practically increased fourfold. One cartridge tape (555-feet tape length) can store 72 MB of data when the data are synthesized. The time information is from a clock processor which can be adjusted at any time by a one minute pulse supplied from a precision clock or a 40 kHz standard time radio. Two field experiments showed the DOBSH worked correctly and proved its usefulness.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "128309", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kasahara, Junzo"}]}, {"nameIdentifiers": [{"nameIdentifier": "128310", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Takahashi, Masayoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "128311", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Matsubara, Tadayasu"}]}, {"nameIdentifiers": [{"nameIdentifier": "128312", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Komiya, Mitsunobu"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000032903", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00162258", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00408972", "subitem_source_identifier_type": "ISSN"}]}, "item_4_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "453", "subitem_subject_scheme": "NDC"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute, University of Tokyo"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}, {"subitem_text_value": "\u6d77\u5916\u7269\u7523\u682a\u5f0f\u4f1a\u793e"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u7b20\u539f, \u9806\u4e09"}], "nameIdentifiers": [{"nameIdentifier": "128305", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u9ad8\u6a4b, \u6b63\u7fa9"}], "nameIdentifiers": [{"nameIdentifier": "128306", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u677e\u539f, \u5fe0\u6cf0"}], "nameIdentifiers": [{"nameIdentifier": "128307", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u5c0f\u5bae, \u5149\u6607"}], "nameIdentifiers": [{"nameIdentifier": "128308", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ji0601002.pdf", "filesize": [{"value": "1.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1100000.0, "url": {"label": "ji0601002.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/32903/files/ji0601002.pdf"}, "version_id": "4a258da3-ec76-411d-b47a-f33145b7bf6e"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Mass Storage Digital Ocean Bottom Seismometer and Hydrophone (DOBSH) Controlled by Micro-processors Using ADPCM Voice Synthesizing", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Mass Storage Digital Ocean Bottom Seismometer and Hydrophone (DOBSH) Controlled by Micro-processors Using ADPCM Voice Synthesizing", "subitem_title_language": "en"}]}, "item_type_id": "4", "owner": "1", "path": ["80/4535/4777/4785", "9/504/4538/4779/4786"], "permalink_uri": "https://doi.org/10.15083/0000032903", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2008-05-30"}, "publish_date": "2008-05-30", "publish_status": "0", "recid": "32903", "relation": {}, "relation_version_is_last": true, "title": ["Mass Storage Digital Ocean Bottom Seismometer and Hydrophone (DOBSH) Controlled by Micro-processors Using ADPCM Voice Synthesizing"], "weko_shared_id": -1}
