Title: Fusing detector
Inventor: MIYAKE YASUAKI
IPC: H02H3/24
Filed: 1987-05-27
Abstract: PURPOSE:To make it possible to detect the fusings of fuses with certainty without having any relation to the number of fusing by inputting the voltage of current in-coming side and of out-going side of the fuse and providing an insufficient voltage detecting element that operates when a voltage of a specified value or below is detected. CONSTITUTION:When the fuses FA and FB of single phase or two phase are fused altogether, a zero phase voltage detecting element 2 detects the zero phase voltage V0 to give a signal to an AND gate 4. On the one hand, a zero phase current detecting element 3 does not detect the zero phase current 10, so the AND gate 4 outputs a signal and outputs a fusing signal FO through an OR gate 13. When all of the fuses FA-FC is fused, both of the zero phase voltage detecting element 2 and the zero phase current detecting element 3 don't operate. On the other hand, the voltage Va2 of current out-going side of the fuse FA is terminated, so an undervoltage detecting element 11 operates to give a signal to an AND gate 12. The voltage of current in-coming side of the fuse FA exists, so the undervoltage detecting device 10 don't operate. Accordingly, the fusing signal FO is outputed.

Abstract: PURPOSE:To make a lifeboat touch water smoothly by starting to run a lift winch for boat fall on the ship while applying a given tension to the boat rope when the boat reaches a specified position above the surface of sea. CONSTITUTION:After passengers and crew are on board, a lift winch is started to run with a first remote controlling cable 8 to lower the lifeboat 4 to a specific position above the surface of sea (for example, 3m above the surface of sea) and stop it temporarily. The detection of the specific position is done by a sea surface detector 9 hanging from the bottom of the lifeboat 4. Then, an automatic tension mechanism built into a winch 6 for the boat fall is operated with the second remote controlling cable 10 to apply a given tension to the boat fall 7 and then, the boat is lowered. Thus, when the boat touches water, the boat rope 7 is extended with a specific tension thereby enabling the boat to touch water smoothly not subjected to action of a lateral force.
