Abstract: An apparatus for cleaning a sensor includes: at least one fluid flow path unit assembled and arranged to correspond to a size and a field of view (FOV) region of a sensor unit and formed with a spray flow path for flowing a fluid supplied through an inlet nozzle, a cover unit coupled to each of the fluid flow path units to shield an opened upper surface of the fluid flow path unit, and a spray nozzle unit selectively coupled to the cover unit and formed so that the fluid flowing along the spray flow path is sprayed toward the FOV region.

Abstract: There is provided a method for manufacturing a rare earth sintered magnet having a stable magnetic performance, by uniformly distributing a heavy rear earth element to the surface of the magnet and the grain boundary inside of the magnet by using a mixture of a heavy rare earth compound or a heavy rare earth metal alloy and a rare earth magnet powder, to lower a decrease rate of the magnetic characteristics based on the temperature of the rare earth sintered magnet.

Abstract: A window jig complex structure includes a window jig and a protective cap extended from the window jig. The window jig includes a main jig part having longer sides extended in a first direction and shorter sides extended in a second direction, a first short side jig part bent from one of the shorter sides of the main jig part in a thickness direction at a first side of the main jig part, and a second short side jig part bent from another of the shorter sides of the main jig part at a second side of the main jig part. The protective cap is coupled with the second short side jig part.
