Abstract: A railess variable seatback type rear seat includes: a linear movement device configured to convert a rotation of a motor into a linear movement; a sliding movement device configured to convert the linear movement into a sliding movement in which a seat cushion is pushed forward or backward; and a reclining angle change device configured to convert the sliding movement into a reclining movement, and to fold a seatback, which is connected to the seat cushion, forward or to recline the seatback backward.

Abstract: In the case of a gas in which several gases are mixed, a type and concentration of the gas may be incorrectly measured when measured using only an optical band-pass filter. The invention of the present application is directed to providing a technology in which a plurality of broadband band-pass filters having overlapping regions are provided to calculate a magnitude of absorption for each wavelength band for light passing through each broadband band-pass filter, thereby identifying the presence of a gas of interest and the presence of a gas other than the gas of interest.

Abstract: The present invention relates to a novel polycyclic compound employed in an organic layer of an organoelectro luminescent device, wherein the organoelectro luminescent device employing the compound according to the present invention has remarkably improved luminous efficiency and a long lifespan. According to the present invention, it is possible to implement a highly efficient and long-life organoelectro luminescent device that can be effectively applied to various display devices.

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 is an apparatus for verifying a malicious code machine learning classification model, which includes: a main feature processing subsystem performing feature extracting and processing functions in an input file; and a multi-layer cyclic verification subsystem performing multi-layer verification in order to determine whether the file is normal or malicious based on the extracted and processed features to verify a machine learning model that classifies malicious codes, thereby ensuring reliability of a prediction result for a machine learning model.

Abstract: A load line type phase displacement unit which is capable of reducing the time which is required for designing the system and increasing the system fabrication efficiency by simply adjusting a phase difference of an input signal by adjusting the length of a stub after the impedances of a main line and a stub are made identical with a characteristic impedance. The unit a main line unit having a main line having a characteristic impedance Z.sub.0 and an identical impedance Z.sub.c and a plurality of stubs having an impedance Z.sub.c of the main line and an identical impedance and being capable of changing a phase difference of an input signal, and a sub-line unit having a stub having an impedance which is identical with the characteristic impedance Z.sub.0 of the main line and a sub-line which is connected in parallel with the stub for compensating for error information based on the malfunction of the main line unit.
