Abstract: An embodiment roof structure for a vehicle body includes a roof side body disposed on both sides of the vehicle body and including a side closed section along a length direction of the vehicle body, a roof ring assembly mounted inside the roof side body and including a reinforcement closed section adjacent to the side closed section along the length direction of the vehicle body, a moving guide portion mounted to the roof ring assembly, and a moving roof detachably mounted on the roof ring assembly and configured to be slidable along the moving guide portion.

Abstract: An embodiment roof structure for a vehicle includes a roof rail assembly configured to be connected to side structures disposed on both sides of a vehicle body, the roof rail assembly including an opening defined therein, a removable roof panel detachably provided in a first section of an area of the roof rail assembly, the first section including an edge region of the opening, and a fixed roof panel connected to a second section of the area, the second section being outside the first section.

Abstract: The present invention relates to a manufacturing apparatus and method for customizing a H2/CO synthetic gas in a desired ratio by producing a synthetic gas in which H2 and CO are mixed through hydrolysis of both carbon dioxide and a nitrogen compound with low power. In a low-power electrochemical apparatus for producing a synthetic gas according to the present invention, by performing the reduction of the carbon dioxide at the cathode and the oxidation of the nitrogen compound at the anode at the same time, carbon dioxide conversion efficiency may be improved 30% or more compared to the conventional carbon dioxide conversion system, and a synthetic gas with a desired H2/CO ratio may be produced by controlling the H2/CO ratio of the produced synthetic gas, and by reducing a driving voltage, the corrosion problem of electrode materials may be inhibited and the durability of electrodes may be increased.

Abstract: A vehicle body rear connection structure includes an extension rear transverse that connects a pillar member disposed in a vertical direction of a vehicle body to a transverse member disposed in a width direction of the vehicle body at a rear of the vehicle body, and of which a seat belt mounting portion is formed, and a reinforcement transverse extension which is mounted on a side of the extension rear transverse, and a lower portion of which is connected to a floor panel.
