A power circuit for a battery for, even when an idle-stop operation is continuously performed, preventing reduction of an electric power supplied to a motor at start-up to obtain a set engine rpm. The power circuit includes a series-connected power supply in which a battery having a load and a capacitor group are connected in series with each other, a DC / DC converter for shifting electric power between the battery and the capacitor group, and between the battery and the load, and a controller for controlling the DC / DC converter. The controller detects the voltage of the capacitor group, and when the voltage detected is lower than a first threshold voltage, controls the DC / DC converter so that the capacitor group is charged with electricity.

Flat electrolytic capacitors, particularly, for use in implantable medical devices (IMDs), and the methods of fabrication of same are disclosed. The capacitors are formed with an electrode stack assembly comprising a plurality of stacked capacitor layers each comprising an anode sub-assembly of at least one anode layer, a cathode layer and separator layers wherein the anode and cathode layers have differing dimensions that avoid electrical short circuits between peripheral edges of adjacent anode and cathode layers but maximize anode electrode surface area. The electrolytic capacitor is formed of a capacitor case defining an interior case chamber and case chamber periphery, an electrode stack assembly of a plurality of stacked capacitor layers having anode and cathode tabs disposed in the interior case chamber, an electrical connector assembly for providing electrical connection with the anode and cathode tabs through the case, a cover, and electrolyte filling the remaining space within the interior case chamber. The plurality of capacitor layers and further separator layers are stacked into the electrode stack assembly and disposed within the interior case chamber such that the adjacent anode and cathode layers are electrically isolated from one another. The anode layer peripheral edges of the anode sub-assemblies of the stacked capacitor layers extend closer to the case side wall than the cathode peripheral edges of the cathode layers of the stack of capacitor layers throughout a major portion of the case chamber periphery. The separator layer peripheral edges extend to the case periphery and space the anode layer peripheral edges therefrom. Any burrs, debris or distortions along or of any of the anode layer peripheral edges causing the anode layer edges to effectively extend in the electrode stack height direction causes the anode layer peripheral edges having such tendency to contact an adjacent anode layer. In this way, anode layer surface area is maximized, and short circuiting of the anode layers with the cathode layers is avoided. A case liner can also be disposed around the electrode stack assembly periphery.

An object of the present invention is to provide a management technique for managing power supply modules. In multiple computer equipment 100, in response to a load state, if an operation system 1101 issues a command that changes a processor state of a processor 1021 to a sleep state, a management module 107 is notified through a management network MI that the processor state has changed. The management module 107 holds a system information 108, and performs the steps of: updating system information 108 because the processor state has changed; from this system information 108, calculating the power consumption required for the multiple computer equipment 100; determining the number of required AC-DC power supply modules 1061, 1062, . . . to be operated; and changing the number of operating AC-DC power supply modules 1061, 1062, . . . by use of a control interface PA.

The present invention relates to a method of monitoring line faults in a medium voltage network (1) of the type comprising an electricity generating plant (3) supplying electricity to a plurality of customers over a network of medium voltage power lines (5), a control centre computer (9) and a plurality of measurement sensors (7) located remote from the electricity generating plant on the medium voltage power lines, each of the measurement sensors (7) further comprising three individual measurement units, each measurement unit mounted on a different phase of the medium voltage power line (5) with respect to the other measurement units of that measurement sensor, and each measurement sensor (7) having means to communicate with the control centre computer (9). The method includes the steps of synchronizing the measurement sensors (7) and thereafter calculating the out of balance current for the medium voltage line (5) on a cycle by cycle basis. On the measurement sensor (7) detecting a fault in the line a line fault measurement report is sent to a control centre computer (9) for further analysis. The method allows for the determination of the likely cause of a fault as well as the likely location of a fault.

A magneto-resistive device has a magnetic free layer (33), a magnetic pinned layer (31) having a magnetic moment larger than that of the magnetic free layer, and an intermediate layer (32) provided between the magnetic free layer and the magnetic pinned layer. The negative-resistance device is characterized in that the negative-resistance device shows negative resistance by making the magnetic free layer continually change the magnetization direction along with the increase of the voltage which is applied to a magneto-resistive device so that electrons flow into the negative-resistance device from a magnetic free layer side.
