    摘要: An optical waveguide device has a function of removing or suppressing a higher-order mode component of propagating light. The optical waveguide device includes a curved waveguide having a curved shape where a curvature continuously changes. A first waveguide is coupled to one end of the curved waveguide and a second waveguide is coupled to the other end of the curved waveguide. A curvature of the first waveguide and the curvature of the curved waveguide are equal to each other in a coupling point in which the first waveguide is coupled to the curved waveguide, and a curvature of the second waveguide and the curvature of the curved waveguide are equal to each other in a coupling point in which the second waveguide is coupled to the curved waveguide.

    摘要: An optical device includes a rib waveguide that is a thin-film lithium niobate (LN) crystal, a buffer layer that is laminated on the rib waveguide, and an electrode that applies voltage to the rib waveguide. The buffer layer includes a thick-film part that is laminated on a rib of the rib waveguide, and thin-film parts that are laminated on slabs of the rib waveguide, where the slabs are located on both sides of the rib, and that have smaller thicknesses than a thickness of the thick-film part.

    摘要: An outdoor unit of an air conditioner includes a housing, a fan inside the housing and configured to cause air to flow and a machine room inside the housing at one side of the fan. A first partition inside the housing includes an inlet hole through which air flow from the fan enters the machine room. A second partition inside the housing, between the fan and the machine room, includes an outlet hole through which air in the machine room is sucked toward the fan. A fan guard is in front of the fan and includes an opening portion on one side of the fan guard that is positioned toward the first partition such that the air flow from the fan moves toward the machine room. A front cover, in front of the first partition, is configured to guide air having passed through the opening portion of the fan guide to the inlet hole of the first partition.

    摘要: Disclosed herein is a cleaner having an improved structure configured to improve the cleaning performance. The cleaner comprises a suction unit provided inside a body. The suction unit includes an impeller configured to suction air by rotating about a shaft, and a diffuser configured to guide air discharged from the impeller. The impeller includes a hub, and a blade disposed on the hub, and provided with a leading edge disposed in an upstream side in a direction in which air introduced into the suction unit flows, and a trailing edge disposed in a downstream side in the direction in which the air introduced into the suction unit flows. The leading edge of the blade forms an inclination of 60 degrees or more and 80 degrees or less with respect to an axial direction.

    摘要: An electronic device comprises: a memory to store an image input; a backlight unit; a driving unit to output a driving current to the backlight unit; and a processor to identify, based on a grayscale value of the image, a first intensity of the driving current corresponding to one from among a plurality of time sections of a backlight dimming section, obtaining, based on the identified first intensity, a first control value that allows control of an intensity of the driving current, providing a second control value, which is greater than a first control value to the driving unit, that allows the driving unit to output a driving current of a second intensity that is greater than the first intensity, and provide the first control value to the driving unit that allows the driving unit to output the driving current of the first intensity during the one time section.
