IPC: E05B81/54
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of a device by setting the same output logic for both setting and resetting sampling circuits when an oscillation circuit stops its oscillation. SOLUTION: The reset signals are supplied to the chattering avoiding circuits 6 to 8, a real function circuit block 15 and a latch circuit 12.

IPC: F04D25/16
Filed: 1986-09-19
Abstract: PURPOSE:To prevent buzzing phenomenon of a fan, by providing a means for transmitting the rotation between a plurality of fan drive shafts. CONSTITUTION:A rotation transmitting means, i.e. a V-belt 1, is stretched between cooling fans 4, 5 which are driven by means of motors 2, 3.
