Abstract: In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

Abstract: A remote control apparatus is provided.

Abstract: Provided is an electronic device. The electronic device includes a communicator that wirelessly connects the electronic device to an external device, and a controller that controls the communicator and transmits a wake-up signal to the external device, in response to an input to turn on the power of the electric device, to instruct the external device in a standby state to initiate an audio output preparing operation. The standby state corresponds to a state in which the external device attempts to establish a connection.

Abstract: A method for manufacturing a hollow hydro-formed product using a multi-tube assembly is provided, which comprises the steps of: (a) stably placing a multi-tube assembly in a Die, the hollow inner tube having fluid channel holes radially formed therethrough; (b) injecting fluid into the inner periphery of the inner tube; (c) applying fluid pressure to the inner periphery of the outer tube by the fluid while the fluid is discharged through the fluid channel holes of the inner tube; and (d) obtaining a formed product having an intended outer peripheral shape completed according to diameter-enlargement and plastic deformation of the outer tube. The inner periphery of the outer tube is pressed and hydro-formed by discharging the fluid through the fluid channel holes of the inner tube formed through the inner tube of the multi-tube assembly.

Abstract: A warm hydro-forming device comprises: an upper mold and a lower mold respectively mounted to an upper mold die and a lower mold die; a lifting die installed to the lower mold die through a guide unit, an upper portion of the lifting die being connected to the upper mold die through a lifting unit to cooperatively operate in an upward and downward direction with the upper mold die; a pair of hydraulic pressure cylinders for providing an axial compression force to the tube component and supplying a forming hydraulic fluid into the tube component; an ascending and descending unit for ascending or descending the upper mold die; and a heating unit associated with the lifting die such that the heating unit can move toward or away from the tube component. The heating unit heats the tube component and a forming hydraulic fluid through a high frequency induction heating.
