Abstract: A wind-water machine set is an evolving jet machine that moves the internal engine to the outside of the sleeve to work, instead of using a water jet as the main and air-jet as the auxiliary. When a ship uses multiple groups of wind-water machine set, there is a master control center for overall control and coordinated operation. Controlling the propulsion system makes the ship move forward and backward in an orderly manner. Control the surfing system to eliminate the bow water resistance and cooperate with the propulsion system. The steering control system is controlled to make the ship easy to operate the steering. Control the balance system to keep the ship balanced without swaying the roll angle. Control the draught system so that ships do not need ballast water. So that the ship can sail at super high speed, super fuel-efficient and safe.

Abstract: A coffee maker includes a main body and a movable module. The main body includes a cup holder, a liquid container, and a frame. The cup holder carries a coffee cup set. The liquid container is disposed on the cup holder for accommodating a liquid. The frame supports the liquid container. The movable module connects the cup holder or the frame to translate and rotate the frame for more evenly melting the coffee.

Abstract: A bicycle folding device comprising a first folding portion and a second folding portion. The first folding portion has a groove, a first axial hole, an axial arranged guide hole, a buckling groove. The second folding portion has an inner axial hole. The pivotal unit serves to pivot the first folding portion and the second folding portion. The quick-detaching unit serves to position the second folding portion. A lever set is placed at a middle section between the second inner end and the second outer end. The lever set has a lever, a handle at a front end of the lever; and a key which is supported by an elastomer and is at a distal end of the lever set. By above structure, the bicycle frame can be assembled and detached easily and firmly. No noise occurs as the bicycle frame is transferred.
