摘要： Disclosed is a method for forming a buffer layer for growing gallium nitride single crystals on a sapphire substrate using hydride vapor phase epitaxy (HVPE), wherein the buffer layer is formed in the form of a doped vertical gallium nitride (GaN) single crystal film with a nanoporosity of 0.10 to 0.15 μm on the sapphire substrate by reacting HCl and NH3 as a Group III/V mix gas.The nanoporous buffer layer interposed on the interface between the sapphire substrate and galluim nitride reduces tensile stress generated by the difference in thermal expansion coefficient between gallium nitride and the sapphire substrate, enables growth of the gallium nitride layer to a thickness of 1 micrometer (m) to several millimeters (nm) without causing cracks, and reduces the lattice constant difference to improve crystallinity.

摘要： A walk-in apparatus for vehicle seats can be constructed of parts required to realize the walk-in operation, thus reducing the production cost and the weight of the apparatus. Moreover, apparatus can reduce the volume of the entire apparatus so that it can be easily applied even to a small-sized seat, for example, that of a small vehicle.

摘要： A walk-in and folding apparatus for a seat includes a locking link installed on a cushion frame by means of an elastic hinge, and connected with a locking unit via a first wire so as to, upon rotation, release the locked locking unit, and a walk-in pin installed on a frame of a seat back by means of another elastic hinge, protruding towards the locking link so as to, upon folding of the frame of the seat back, force the locking link to rotate, and connected with a folding lever in such a manner as to rotate in association with the same so as to, upon a folding action caused by operation of the folding lever, rotate so that it does not interfere with the locking link.
