Abstract: An electrocardiogram analysis assistance device (10) including: a peak estimation model (13C) employing waveform data of partial segments of waveform data in an electrocardiogram as input information and employing peak information indicating whether or not a predetermined type of peak related to electrocardiogram analysis is present as output information; an analysis waveform acquisition unit (11C) that acquires waveform data in an electrocardiogram for analysis; an analysis waveform select and extract unit (11D) that selects and extracts waveform data of a predetermined first period from the waveform data acquired by the analysis waveform acquisition unit (11C) as analysis divided waveform data, while each time shifting a predetermined shift period that is a shorter period than the first period; and a derivation unit (11E) that derives the peak information by inputting the analysis divided waveform data selected and extracted by the analysis waveform select and extract unit (11D) into the peak estimation mod

Abstract: A centrifugal extractor of non-contact journaled construction is provided in which, even under the environments of corrosive gase and mist-like liquid such as nitric acid mist generated in the reprocessing of a spent nuclear fuel, no problem in corrosion or deterioration of parts occurs and high reliability is obtained, and operation is enabled for a long period of time free from maintenance. A rotor 12 housed in a rotor housing 10 is journaled by a main shaft 14 and rotated and driven by a motor 16. The main shaft is surrounded by a drive-portion housing 30, and has a thrust magnetic disk 36 on the upper end and radial magnetic disks 46, 48 and a motor-rotor portion 54 in the circumference thereof.

Abstract: A centrifugal extractor has a rotor supported rotatably in a housing 10, and an aqueous phase liquid and an organic phase liquid are supplied to the outer circumference of the rotor and mixed between the housing and the rotor. A mixed phrase liquid is sucked into the rotor and is separated into two phases in a centrifugal force field generated in the inside of the rotor, and the separated aqueous phase liquid and organic phase liquid are discharged to an aqueous phase collector 50 and an organic phase collector 44, respectively. A cavity portion is provided in the center of the rotor, and a neutron absorption body 60 is disposed in the cavity portion. Preferably, the rotor has a lower rotating and supporting mechanism (such as a sliding bearing 66), and a neutron absorption material is sealed into the lower rotating and supporting mechanism. By such a centrifugal extractor, criticality safety and durability can be enhanced, even when the extractor is designed to be larger-size and larger-capacity.
