摘要:
A superconducting junction element has a lower electrode formed by a superconductor layer, a barrier layer provided on a portion of a surface of the lower electrode, an upper electrode formed by a superconductor and covering the barrier layer, and a superconducting junction formed by the lower electrode, the barrier layer and the upper electrode. A critical current density of the superconducting junction is controlled based on an area of the lower electrode.

摘要:
A process for forming a thin oxide film on an underlying surface adapted for film formation thereon according to a radio frequency magnetron sputtering method using an oxide target(s). The excitation frequency is higher than 13.56 MHz and provides a lower negative target self-bias voltage permitting improved film formation.
摘要:
A transmission line protection system arranged such that a leakage current detector is provided at an end of an insulating device such as an insulator connected at one end to a corresponding one of arms of a steel tower and connected at the other end to a transmission line of each phase, thereby detecting an arrester leakage current flowing in the transmission line of each phase, an output signal of the leakage current detector being led to a repeater through an optical fiber cable, an output of the repeater being transferred to a control/supervisory board in a substation through an optical fiber cable. In the control/supervisory board, preferably, a received digital signal which was converted from an analog signal at said leakage current detector is displayed on a cathode ray tube. In such an arrangement, it is possible to smoothly perform supervision of the status of the transmission lines without causing maloperations due to influences from the transmission lines.

摘要:
According to an aspect, an information processing device includes: a receiver configured to receive information related to a plurality of smart meters; a controller configured to determine presence or absence of an anomaly in each of the smart meters based on a reception status of the information from each of the smart meters; and an output unit configured to output information indicating presence or absence of an anomaly in each of the smart meters. The receiver receives the information from the smart meters in a cycle of a first predetermined time. The controller determines that an anomaly is occurring in a smart meter from which information has not been obtained for a second predetermined time that is longer than the first predetermined time. The second predetermined time is n times as long as the first predetermined time, and n is equal to or greater than 2
