Abstract: Disclosed is to an improvement apparatus of surface roughness of hot/cold rolled stainless steel coils and the method thereof. The present invention provides an improvement apparatus of surface roughness of hot/cold rolled stainless steel coils including a water spray unit for spraying water on a surface of a cast stainless steel slab; a cutting unit for cutting the stainless steel slab; and a high-pressure water spray having at least one nozzle in a region where the stainless steel slab is cut by the cutting unit and discharged and installed to be symmetric in upper and lower parts of the stainless steel slab; and a roller brush installed to be in contact with and symmetric in the upper and lower parts of the stainless steel slab passed through the water spray so as to rotate at a high speed.

Abstract: Disclosed is an on-line quality prediction system for stainless steel slab and the predicting method using it, which can allow produced slab quality to predict in high precision on the on-line using a network based system by collecting all operation data available from a steel making process to a continuous casting process and then using them as a metallurgical calculation evaluating model through thermodynamics and statistics programs, the system comprises: a main computer collecting and storing information from a production line for the stainless steel slab; a thermodynamics calculation only computer mutually communicating with the main computer; and a server computer mutually communicating with the main computer, whereby it can overcome a limitation of a predicting method due to existing operation data and allow produced slab quality to predict in high precision on the on-line using a network based system by collecting all operation data available from a steel making process to a continuous casting process

Abstract: A system and method for supplying power to an Anti-lock Braking System (ABS) for a vehicle includes: determining whether an ignition key has been turned on; comparing voltage of a first battery unit, configured to apply the power to an ABS actuation unit, with voltage of a second battery unit, connected to the first battery unit, if the ignition key has been turned on; determining whether the ABS actuation unit is operating if the voltage of the first battery unit is lower than the voltage of the second battery unit; and charging the first battery unit with the power if the ABS actuation unit is operating, and balancing the voltage of the first battery unit and the voltage of the second battery unit if the ABS actuation unit is not operating.

Abstract: A nonvolatile memory device having self-presence diode characteristics, and/or a nonvolatile memory array including the nonvolatile memory device may be provided. The nonvolatile memory device may include a lower electrode, a first semiconductor oxide layer on the lower electrode, a second semiconductor oxide layer on the first semiconductor oxide layer, and/or an upper electrode on the second semiconductor oxide layer.

Abstract: Provided is a light emitting device assembly. The light emitting device assembly includes a submount including bumps, each having a bonded surface and a lateral surface surrounding the bonded surface; and a light emitting device including pads, each having a bonded surface corresponding to a bonded surface of a corresponding bump. Herein, edges of the bonded surface of each of the bumps are spaced a predetermined distance inward from edges of a corresponding pad.
