Abstract: A maintenance system for a wide area work-flow system in which plural work-flow systems operates with linking via a wide area network. A historical information management unit is connected to the wide area network and maintains operation history information for each of the plural work-flow systems operating automatically according to the work-flow defining a processing job flow. When a work-flow system of the plural work-flow systems recovers from system-down, mismatch or discrepancy is detected by comparing the historical information of the work-flow system with the historical information of the other work-flow systems of the plural work-flow systems. To improve the reliability, the operation history information stored in the historical information management unit is used when the work-flow systems are recovered from system-down.

Abstract: A plurality of SQUID flux sensors are supplied with their respective bias currents at the same time from a bias source. A superconducting multiplexer multiplexes output signals of the SQUID flux sensors during an interval of time when the bias currents are supplied to the SQUID flux sensors. A multiplexer, placed in a room-temperature environment, distributes each of the multiplexed output signals of the SQUID flux sensors to a respective one of the output terminals which correspond to the SQUID flux sensors. Each signal which has been output to an individual output terminal is counted by a counter, so that an external magnetic flux to a corresponding SQUID flux sensor is measured.

The fluxmeter further includes an offset detection unit which detects the offset quantity of the counter unit generated by the magnetic flux trapped by the SQUID ring, and a feedback unit that feeds back to the flux sensor unit a signal that is obtained based on the detected offset quantity and the counted result of the counter unit.

Abstract: An apparatus is provided for measuring a very weak magnetic field generated by a human body, etc. External magnetic noise components coming from other magnetic sources and existing around an object whose magnetic field is to be measured are detected by compensation coils of the apparatus. The compensation coils are oriented in multiple dimensional directions. The detected noise components are weighted and added to each other to correctly find the noise components. Thereafter, the noise components mixed in the objective very weak magnetic field are removed, thereby correctly measuring the very weak magnetic field.

Abstract: In a multi-channel SQUID fluxmeter for detecting magnetic flux signals by use of an array of SQUID flux sensors each comprising a digital SQUID for providing a pulse output, multiplexers and the like are appropriately used to allow pulse signals output from the SQUID flux sensors to be switched on a time series basis in order to obtain a magnetic flux signal for each channel. Thus, only one processing circuit need to be provided for a large number of SQUID flux sensors, thus reducing the scale of the fluxmeter and making the device small.
