During gear retraction, It looks like the 6 wheels gear door open, then a small part of them fold and they close with an opening this time. Is that so? Is it only a feature of the A380 or do other airliners have the same kind of retraction?

The subcontractor is probably Messier.
The door your talking about is probably a fixed door attached to the body gear. I couldn't tell from the pictures, but it appears that it would attach to the front of the gear and "close" as the gear retracts.

Discovery had a 2 hour documentary on the A380 last night, which included a bit on Goodrich & the test they did to see if the landing gear would withstand the forces on impact. Quite interesting, really.
Of course, as a lead up, they showed the low res clip of a KE 747 doing a horrible landing at Kai Tak, to point out the forces that may act upon a landing gear.

Quoting Brons2 (Reply 2): who's the landing gear subcontractor on the A380? Goodrich?
In Toulouse, France on April 27, 2005 the Airbus A380 took to the skies for the first time. Goodrich technology was on board for this revolutionary aircraft's test flight.
Goodrich is one of the world's largest suppliers of landing systems and provides both the main body and wing landing gear for the A380. Though Goodrich was already a major supplier for Airbus, it was the first time the company had been selected to provide landing gear for an Airbus aircraft. The components for the landing gear system are produced by Goodrich’s Landing Gear division and involve manufacturing facilities at Oakville, Ontario, Canada; Cleveland, Ohio; Tullahoma, Tennessee; and Krosno, Poland. The final gear integration takes place at the Goodrich facility in Toulouse, France before delivery to Airbus’ final assembly line.
Along with providing state of the art landing gear for the A380, Goodrich is also launching the next generation of evacuation systems with its A380 work package. Goodrich will supply 16 evacuation slide systems per aircraft, which are designed to be 10% lighter than current slides while still meeting all performance requirements.
Goodrich is also supplying innovative High-Density Discharge (HID) and LED-based exterior lighting, award-winning variable frequency technology for the aircraft’s power generation system (through its Aerolec joint venture with Thales) and flight controls that take advantage of the latest power by wire technology. And Goodrich will provide the primary and standby air data systems. The primary air data system will feature SmartProbeTM, another new Goodrich technology, which uses innovative multi-function sensing probes to aid reliability.
Goodrich is also providing an automatic ice detection system, and will bring its experience in aircraft materials and structures to bear in the development of the aircraft’s cargo system and with several structural components. Most recently, Goodrich was selected by Airbus to provide the aircraft’s cabin attendant and cockpit occupancy seats.

The outer body gear doors do indeed have a sub-segment each which folds out only when the gear is retracted. When it is extended this extra panel (which is hinged on the main door panel) is folded away to leave an opening just for the pylon.
The option to mechanically link the cover panel to the strut does not exist with the retraction mechanism used; The fold-away panel probably reduces drag and noise as well vs. a panel sticking out together with the extended pylon.
