Abstract: A memory system, a memory controller are provided. The memory system includes: a memory device; and a memory controller configured to: control a patrol scrubbing operation in which data is read from and re-written to the memory device, based on a scrubbing cycle; and adaptively adjust the scrubbing cycle based on a comparison of an error count value of the memory device and a plurality of risk threshold values.

Abstract: A method for preparing error recovery of a memory device included in a memory system includes performing a training operation of the memory device upon power-on of the memory system, booting an operating system into a normal mode by operating the memory device using a selected operation frequency of a plurality of operation frequencies based on results of the training operation, detecting an error frequency among the plurality of operation frequencies in response to a change of the selected operation frequency of the memory device by the operating system, the error frequency being an operation frequency which causes at least one error in the memory device, and storing information regarding the detected error frequency in a first register included in a memory controller associated with the memory device.

Abstract: Provided are: an optical laminate comprising a second adhesive layer, a second adhesive layer laminated on the second adhesive layer, and a light shield part laminated between the first adhesive layer and the second adhesive layer; an optical member comprising same; and an optical display device including same.

Abstract: Disclosed is a device for checking a field of view of a surveillance camera for on-site work, which rapidly and accurately checks a field of view in a field through a projection image without checking a filmed image through a monitor, is capable of installing the surveillance camera and adjusting a position of the surveillance camera, and is capable of outputting a visual warning according to a linkage with various image surveillance systems.

Abstract: The present invention relates to a novel naphthyridinone derivative compound, a pharmaceutically acceptable salt thereof, a hydrate thereof, or a stereoisomer thereof, which are each relevant to a compound for inhibiting ENPP1, a composition for inhibiting ENPP1, and a method for inhibiting ENPP1.

Abstract: Heat exchanger comprising a pair of header tanks which are arranged to be spaced apart from each other, a plurality of tubes formed in two columns in the width direction so that both ends are connected to the pair of header tanks, and a plurality of fins interposed between the tubes and coupled to the tubes. The header tank is configured so that a first tank and a second tank are respectively coupled to one header having a central bent portion in the center portion in the width direction, which provides easy assembling of headers and tanks of two heat exchangers. Thermal stress caused by the temperature difference between two heat exchanging media is blocked so that damage to a coupling portion where the two heat exchangers are coupled or a bonding portion formed through brazing can be prevented. Thus, leakage of the heat exchanging medium can be prevented.

Abstract: The present invention relates to a polyester resin. The polyester resin is useful for bottles, sheets, multilayer sheets, stretched films and fiber applications due to excellent heat resistance and transparency, and in particular, the polyester resin has little deterioration of physical properties such as yellowing, etc., during processing. A process for making the polyester resin includes an esterification reaction between a dicarboxylic acid that includes terephthalic acid and a diol that includes isosorbide in the presence of a catalyst, followed by a polycondensation reaction on a product of the esterification reaction. In some embodiments, an initial mixing ratio of the dicarboxylic acid and the diol is between 1:1.02 and 1:1.04.

Abstract: A display device includes a display panel including a plurality of pixels, a folding area, a first non-folding area disposed on one side of the folding area, and a second non-folding area disposed on the other side of the folding area, a first adhesive layer disposed on one surface of the display panel, and a code pattern layer. The code pattern layer includes a light absorption layer disposed on one surface of the first adhesive layer, a base layer disposed on the light absorption layer, and a plurality of code patterns disposed on the base layer. A thickness of the base layer is smaller than a thickness of the first adhesive layer.

Abstract: The present invention relates generally to a lead frame which is bended with a predetermined angle many times in order that a sectional area of a punch to form two lead lines which are located in the center of tie bars is increased, and increase the inertial moment as to a sectional area in making a lead frame of a desired shape. And the above-mentioned lead frame comprises a dambar; inner leads which has a certain angle at the part being below half the distance from lead tips to the above-mentioned dambar, and is connected to the above-mentioned dambar; outer leads which is connected to the above-mentioned dambar, and is populated on a circuit board; and tie bars which support the above-mentioned inner leads in case of taping.
