Abstract: Provided is a device for upscaling resolution based on a slice image, in which a low-resolution image is divided into a plurality of slice images so that a high-resolution image is generated. The device includes a convolution operation unit configured to convert a low-resolution input slice image into a high-resolution output slice image using a convolutional neural network. The convolutional neural network includes a cascading block configured to perform a convolution operation using a convolution filter having a predetermined size and a residual operation on an input feature map generated from the low-resolution input slice image to generate an output feature map, and an upscaling block configured to upscale the output feature map to generate the high-resolution output slice image.

Abstract: There is provided a camera module including a plurality of ball bearings to support the driving of a lens barrel at the time of compensating for unintended camera movement due to disturbance such as hand shake. The lens barrel may be driven in first and second directions, independently, by one driving force exerted in the first direction perpendicular to an optical axis and by another driving force exerted in the second direction perpendicular to both the optical axis and the first direction, thereby preventing driving displacement from being generated at the time of compensating for unwanted motion such as hand shake while securing reliability against external impact, and having reduced power consumption at the time of compensating for the disturbance.

Abstract: A coil component includes a body having a first surface, and a first end surface and a second end surface connected to the first surface and opposing each other in a length direction; a support substrate disposed inside the body; a coil portion comprising a first coil pattern and first and second lead-out patterns, each disposed on a first surface of the support substrate; first and second slit portions, respectively defined on edge portions of the first surface of the body to expose the first and second lead-out patterns; and first and second external electrodes disposed on the first and second slit portions to be connected to the first and second lead-out patterns. At least one of the first and second lead-out patterns has a thickness greater than a thickness of each of the first coil pattern and the first dummy lead-out pattern.

Abstract: A coil component is provided. The coil component includes a body having fifth and sixth surfaces opposing each other, first and second surfaces respectively connecting the fifth and sixth surfaces of the body and opposing each other, and third and fourth surfaces respectively connecting the first and second surfaces of the body and opposing each other in one direction, a recess disposed in an edge between one of the first and second surfaces of the body and the sixth surface of the body, a coil portion disposed inside the body and exposed through the recess, and an external electrode including a connection portion disposed in the recess and connected to the coil portion, and a pad portion disposed on one surface of the body. A length of the pad portion in the one direction is greater than a length of the connection portion in the one direction.

Abstract: Disclosed herein is an apparatus for evaluating the safety of a building. The apparatus includes first and second measurement instruments which measure earthquake accelerations of the top and bottom stories, a fast Fourier transform unit which performs fast Fourier transform on the earthquake accelerations, an integration unit which double-integrates the measured earthquake accelerations and creates drift data of the top story and the bottom story, a maximum inter-story drift ratio calculation unit which calculates a maximum inter-story drift ratio, a natural frequency change rate calculation unit which determines a natural frequency of the building, and compares the natural frequency with an ambient natural frequency of the building so as to calculate a natural frequency change rate, and a building safety evaluation unit which compares the maximum inter-story drift ratio and the frequency change rate with preset evaluation criteria and outputs a result of evaluation in the safety of the building.

Abstract: An apparatus for forming a beam member for a torsion beam in a rear wheel suspension system of an automobile wherein said apparatus includes top and bottom dies for forming a U-shaped or V-shaped section and an extension section of the beam member, upper and lower pad-dies coupled to top and bottom dies for forming a rectangular section of the beam member before operation of the top and bottom dies, and left and fight cams installed at both sides of a pipe so as to be horizontally inserted into the pipe by a hydraulic cylinder for maintaining inner shapes of the extension section and the rectangular section, said cams preventing both distortion and wrinkling from occurring on the rectangular section and the extension section of the beam upon operation of the top and bottom dies, thereby allowing the beam member to be formed to have different cross sections at different portions of the beam with complete symmetry, by a single process.

The apparatus comprises top and bottom dies for forming a U-shaped or V-shaped section and an extension section of the beam member, upper and lower pad-dies coupled to top and bottom dies for forming a rectangular section of the beam member before operation of the top and bottom dies, and left and right cams installed at both sides of a pipe so as to be horizontally inserted into the pipe by a hydraulic cylinder for maintaining inner shapes of the extension section and the rectangular section. The cams prevent both distortion and wrinkling from occurring on the rectangular section and the extension section upon operation of the top and bottom dies, thereby allowing the beam member to be formed to have different cross sections at different portions with a complete symmetry by a single process.

Abstract: The present invention relates to a packing unit for a refrigerator having a detachable door handle, the packing unit comprising an outer case to protect an external appearance of the refrigerator, an upper shock absorber accommodated in the outer case and connected to an upper part of the refrigerator and formed with a handle accommodating part to accommodate the door handle detached from the refrigerator, and a lower shock absorber accommodated in the outer case and connected to a lower part of the refrigerator. An increase of a pack volume due to the door handle is prevented and the door handle is safely accommodated within an additional component the packing unit.
