Abstract: The assistant landing device of a troubled airplane of the present invention comprises a storing chamber under the front end of the airplane, which has a freely opened door, and a strengthen network the front end of which is connected with the airplane body. When the network is expanded from the storing chamber, it will not affect the descent of the front and back landing gears. A plurality of canopy packets arranged as an array are installed on the front and back sides of the network and may be opened by controlling so that a group of canopy packets are formed on the right and left sides of the body of the airplane so that the airplane may be descended slowly. Each of the canopy packets has a large and a small canopy packets and a gas container for being quickly charged with air so that the small canopy packet may be opened.

Abstract: A life parachute including a canopy formed of pieces of fabric sewed together, sheaths extending from the center of the canopy in a spoke-wise manner, and an inflatable envelope connected to a compressed gas container by way of a conduit. The inflatable envelope has a main body in the center thereof and legs extending spoke-wisely from the periphery of the main body; the legs and the main body are interconnected and inflatable. The number of legs is equal to that of the sheaths. The free ends of the legs are inserted into the corresponding sheaths and then secured onto the canopy so that the main body of the inflatable envelope can be maintained at the central portion of the canopy.

Abstract: A container includes a wall body having a projection extending inwardly from the internal wall surface of the wall body and a cavity extending inwardly from the external wall surface of the wall body into the projection with an opening which is located at the external wall surface. A rotatable member is rotatably and unremovably received in the cavity. A portion of the rotatable member protrudes out from the opening of the wall body. Whereby, the rotatable member can be rotated by a user's fingers so as to enhance the aesthetic quality of the container.
