Abstract: An image encoding/decoding method, device and recording medium based on accumulation of a region of interest of the present disclosure may include partitioning a current image to acquire a region of interest, cumulatively expressing the region of interest in a reference image of the current image and decoding the current image based on a reference image in which the region of interest is cumulatively expressed.

Abstract: The present invention relates to a multi-component host material and an organic electroluminescent device comprising the same. By comprising a specific combination of the multi-component host compounds, the organic electroluminescent device according to the present invention can provide high luminous efficiency and excellent lifespan characteristics.

Abstract: Disclosed is a trochoid pump for transferring high-viscosity liquids under high pressure. The trochoid pump includes an idler coupled to an inner through-hole inside a housing to be rotated, a rotor inserted into an inside of the idler, and a shaft configured to rotate the rotor, wherein the idler is provided with an inner toothed groove, into which the rotor is inserted and which has a plurality of projecting teeth, and recessed grooves, which are recessed with a predetermined depth along an outer circumferential surface thereof in a circumferential direction. Unlike an existing gear pump or trochoid pump, the trochoid pump for transferring high-viscosity liquids can reduce a viscous friction force, and can reduce the driving power.

Abstract: Disclosed is a two-liquid-type, double-row structured trochoid pump for transferring high-viscosity liquids under high pressure. A front body, a first housing, a center body, a second housing, and a rear body are successively coupled to form an outer body, and a first idler is coupled to an inside of the first housing. A first rotor is inserted into the first idler, a second idler is coupled to an inside of the second housing, and a second rotor is inserted into the second idler. A shaft is coupled to penetrate the front body, the first housing, the center body, the second housing, the rear body, and the first and second rotors, and the shaft is connected to an external electric motor. Accordingly, transfer equipment can be reduced in size and weight through reduction of an attachment and a controller, which constitute the transfer equipment, into one device.

Abstract: The present disclosure relates to a high-viscosity liquid feeding booster pump. The booster pump includes: a body having an actuator mounted at one side thereof and a discharge valve formed at the other side thereof, the body being formed internally with a chamber; a plunger configured to be inserted into the body, and advanced or retracted relative to the body by the operation of the actuator to generate a compressive force or a suction force; and a charge valve disposed at an intake port formed at an upper portion of one side of the body in such a manner as to be spaced apart from a discharge valve, and configured to be opened or closed in cooperation with the advancing or retracting operation of the plunger to supply a fluid to the inside of the body or interrupt the supply of the fluid.
