Title: 複合材料用のナット板締結具アセンブリ
IPC: F16B37/04

IPC: H01H83/14
Filed: 2008-01-11
Abstract: A residual current device comprises a circuit (CT, 10, 12) for detecting a current imbalance in an AC supply to a load indicative of a residual current and providing a corresponding output. A relay RLA has contacts SW1 in the AC supply to the load. The relay contacts SW1 automatically close when a closing current is passed through the relay and is thereafter maintained closed so long as a holding current, less than the closing current, passes through the relay. A capacitor C1 is connected to the AC supply in parallel with the relay RLA such that, upon application of power from the AC supply, current flows to the charge storage device. An electronic switch SCR2 in series with the relay is turned on when the voltage on the capacitor exceeds the breakover voltage of a Zener diode ZD2 to allow discharge of the capacitor through the relay to provide a current exceeding the closing current, the AC supply thereafter providing a holding current for the relay at least when the supply is at a certain minimum voltage. An output from the current imbalance detecting circuit opens contacts SW3 in series with the relay to interrupt the current flow through the relay.

Abstract: <P>PROBLEM TO BE SOLVED: To prevent information leakage, even if information fed back from a recipient side to a sender side is attacked by an attacker.  <P>SOLUTION: A sender divides secret information into n pieces of distributed secret information, and transmits the distributed secret information to a recipient through n communication paths. The recipient detects the number of error information out of the received n pieces of distributed secret information, and determines whether the number of error information exceeds a predetermined allowable value or not. If the number of error information exceeds the predetermined allowable value, the recipient selects x pieces of distributed secret information out of the distributed secret information, and acquires a mask value for the x distributed secret information. Then, the recipient transmits the mask value to the sender. The sender selects x pieces of distributed secret information out of the transmitted n pieces of distributed secret information, and acquires a mask value for the x pieces if distributed secret information in the same method as that used by the recipient. The sender transmits the selected distributed information until the number of error information becomes smaller than the allowable value, using the fact on whether the received mask value and the acquired mask value match each other, as an error information value. The recipient restores the secret information from the distributed secret information, when the number of error information becomes smaller than the allowable value.  <P>COPYRIGHT: (C)2011,JPO&INPIT
