Abstract: A method of manufacturing a composite electrode for an all-solid-state battery includes: preparing a precursor solution by mixing at least one solid electrolyte precursor and at least one polar solvent; stirring the precursor solution; preparing an electrode slurry by adding an active material to the stirred precursor solution; and heat-treating the electrode slurry and obtaining the composite electrode for the all-solid-state battery, wherein the composite electrode for the all-solid-state battery includes: the active material; and a coating layer disposed on the active material and including a solid electrolyte.

Abstract: A method of manufacturing a filter pipe for vehicles which has an expanded tube portion with a different diameter at one side and is provided with a plurality of through holes formed along a circumferential direction includes: forming the plurality of through holes in a mother member; forming furrows at one end portion of the mother member; forming a planar member having the plurality of through holes and the furrows by a shearing process of the mother member; bending the planar member in a tubular shape and spreading the furrows to form an area where the furrows are formed in an expanded tube shape; and adhering both facing end portions of the planar member so as to form a body having the expanded tube portion at one side thereof.

Abstract: Disclosed are an apparatus and method for testing braking performance. The apparatus of the disclosed invention comprises: a driving unit which generates power; a test unit driven by the driving unit; and a control unit which controls the operation of a braking apparatus to generate a brake force on the test unit and to check braking performance. The present invention uses a rope unit moving at a speed for inducing a braking operation by the rotation of driving sheaves spaced apart from each other, rather than testing braking performance in an expensive elevator test tower, thereby preventing the possible dangers of tests conducted in said test tower. Further, the present invention controls loading capacity simply by controlling the loads of the driving unit to enable easy testing.

Abstract: An actuator for a vehicle capable of selectively opening and closing a waste gate valve provided in a turbocharger is disclosed. The actuator includes a driving motor having a motor shaft, a gear assembly comprising a plurality of gears engaging with each other and with the motor shaft, a connecting unit connected with the gear assembly to move along the operation of the gear assembly, wherein the connecting unit is connected with a waste gate valve provided in a turbocharger housing.

Abstract: An exhaust gas recirculation valve in a vehicle has two valves that are controlled individually by using one driving source. The exhaust gas recirculation valve enables secure operation of a vehicle even if the driving source is out of order. The exhaust gas recirculation EGR valve includes a driving unit having a driving motor for rotating a motor shaft and an interlocking unit for receiving rotational force from the motor shaft. A rod portion moves upon reception of the rotational force. A valve unit at an end portion of the rod portion controls a flow rate of the exhaust gas. A valve housing is coupled to the driving unit as one unit and has an EGR port and a bypass port. The interlocking unit includes a valve return member for rotating the motor shaft forcibly to make the valve unit to move to an initial position.

Abstract: The present invention relates to an exhaust gas recirculation (EGR) valve for a vehicle. The EGR valve includes a valve housing connected to an exhaust line for discharging exhaust gas therethrough, having a flow line with an inside area divided for taking and re-circulating a portion of the exhaust gas to a suction manifold, a driving unit on one side of the valve housing, and a valve unit mounted in a flow line of the valve housing for receiving driving force from the driving unit directly to control flows of the exhaust gas flowing through the flow line at the same time individually, thereby making stable control of the exhaust gas flowing through the EGR valve, preventing damage caused by the high temperature exhaust gas, and preventing the exhaust gas from leaking to an outside of the EGR valve.
