Abstract: There is provided a ferritic lightweight steel which contains 2.0 to 3.0 wt % manganese (Mn), 5.0 to 6.0 wt % aluminum (Al) and 0.1 to 0.3 wt % carbon (C) and has a tensile strength of 900 MPa to 1,108 MPa. The lightweight steel includes ferrite-austenite dual grains as a result of performing low-temperature tempering-induced partitioning (LTP) at 300° C. for 10 minutes after isothermal annealing.

Abstract: A network-based motor control system-on-chip (SoC) and a motor control method. The network-based motor control system includes a network unit; a first processor for exchanging a first data with the network unit and processing a first task related to the first data; a motor; a motor control unit for controlling operation of the motor; a second processor for exchanging a second data related to the operation of the motor with the motor control unit and processing a second task related to the second data; and a data sharing unit for sharing processing results of the first task and the second task by the first processor and the second processor, in which the first task and the second task are concurrently processed.

Abstract: An apparatus of thinning a glass substrate includes at least one chemical spray member, a chemical supply member, and a bath. The chemical spray member includes a first tube and a second tube enclosing the first tube. The first tube has a plurality of first spray holes disposed along a first direction. The second tube has at least one second spray hole disposed at a lateral portion of the second tube along a second direction. The chemical supply member includes a connection tube and a press pump. The connection tube is coupled to the chemical spray member, and the press pump is disposed at an end portion of the connection tube. The bath includes a chemical receiving member for storing chemicals and a fence disposed on the chemical receiving member. The fence receives the chemical spray member.

Abstract: An apparatus for etching a glass substrate includes a container for receiving an etching solution and at least two rollers disposed in the container. The at least two rollers may face with each other. The glass substrate is inserted between the at least two rollers, and the glass substrate is uniformly etched using the etching solution while revolving the at least two rollers.
