    摘要： An output driving circuit is provided that may reduce power consumption by decreasing static current leakage in a liquid crystal display device. The output driving circuit of an output buffer of a source driver integrated circuit may include: an output driving unit including a pull-up transistor and a pull-down transistor coupled to a source line driving signal output terminal; and a sub output driving unit configured to perform an output driving operation together with the output driving unit during a normal operation period of an active horizontal synchronization signal and configured to be disabled during a period in which the horizontal synchronization signal is inactive in response to a control signal, in order to reduce static current leakage flowing through the output driving circuit. Current leakage is reduced in the inactive period of a horizontal synchronization signal in an output driving circuit, thereby reducing power consumption of a liquid crystal display device.

    摘要： A data transmission device for reducing power consumption includes a data source configured to provide data, a data transmission line having a plurality of data transmission sections, and data storage units respectively coupled to the data transmission sections. The respective data storage units determine whether the data storage units store the provided data, and store the provided data based on the determination result. The provided data is sequentially stored into the data storage units, from one end of the data storage units to the other end of the data storage units. A data transmission controller is configured to control the data transmission sections and to transmit the provided data to one of the data storage units. Therefore, the data transmission device may reduce electromagnetic interference (EMI) that is proportional to the current in the source driver.

    摘要： A cutting insert has a top surface, a bottom surface, a plurality of side surfaces that connect the top and bottom surfaces. The side surfaces form an obtuse angle with the bottom surface as well as an acute angle with the top surface. The side surfaces include a first side surface and a second side surface, which form an obtuse angle with each other when seen from the above. A main cutting edge is formed at an intersection between the first side surface and the top surface. An inclined cutting edge, which is only for ramp milling, and a minor cutting edge are formed at an intersection between the second side surface and the top surface. An obtuse angle, which the second side surface forms with the bottom surface, is greater than that which the first side surface forms with the bottom surface.
