IPC: A61M29/02
Filed: 1990-02-23
Abstract: PURPOSE:To achieve a higher insertability with a higher fastening performance and with limited damage to living body by attaching a simple expansion control means to a fastener. CONSTITUTION:A tube body 3 shrinks in a dry condition and an expansion limiting tube 4 gets tight on an external surface of the tube body 3 being slackened in a bellows, while an ERBD tube 2 shrinks as a whole.

Title: Protective relay
Inventor: SATO CHIKAO
IPC: H02H7/045
Filed: 1990-02-23
Abstract: PURPOSE:To prevent unnecessary locking of a protective relay by an unnecessary operation of a second harmonic content rate detecting element even in a region of a fundamental wave current being small, by a construction wherein an output of the relay is locked by the logical product of an output of a main detecting element of the protective relay and an output of the second harmonic content rate detecting element. CONSTITUTION:When a power is supplied to a transformer to be protected, an exciting rush current flows and a ratio-differential element 6 operates, while a second harmonic content rate detecting element 7 operates. As the result, an AND circuit 10 delivers an output '0' to be introduced into an AND circuit 13 through an NOT circuit 11. Even when an output of the ratio-differential element 6 introduces '1' into the AND circuit 13 through a time delay circuit 12, therefore, an output of a relay 1A is locked and thus a false operation of the relay 1A is prevented.
