Abstract: A remote locking release device in a bicycle wheel locking apparatus, including: a remote controller; a light signal receiving unit for generating a locking release signal by a locking release requirement signal received from the remote controller; a position detecting unit for detecting the present position of a locking bar and generating a locking state signal; a controller for generating a relay control signal by the locking release signal and the locking state signal; a relay driving unit for supplying a relay driving voltage by the relay control signal; and a relay for releasing the locking state by the locking bar with falling down a stopper by the delay driving voltage.

Abstract: The present invention relates to an emergency landing auxiliary apparatus of an aircraft using a parachute, whereby a rapid accident crash of an aircraft can be avoided through releasing the chute set inside an apparatus accepting room 11 and the landing distance of the aircraft can be reduced in case of an emergency landing. Therefore, the present invention is effective in decreasing a possible loss of lives and the damage of the aircraft itself.
