Abstract: Disclosed herein is an apparatus for measuring the shape of a 3D object using an interferometer. The apparatus includes a light source unit, a beam splitter, a reference mirror, an actuator, an image pickup device, and a control unit. The light source unit emits light. The beam splitter divides the light from the light source unit. The reference mirror reflects light as a reference beam. The actuator moves the reference mirror. The image pickup device acquires a plurality of interference patterns by causing the reflected beam and the reference beam to interfere with each other. The control unit measures the shape of the object from the acquired interference patterns, outputs reference mirror drive signals to the actuator, and issues an image capture command at the end of image capture time that is shorter than settling time.

Abstract: The present invention relates to an apparatus for manufacturing molten irons by injecting fine carbonaceous materials into a melter-gasifier and a method for manufacturing molten irons using the same.

Abstract: A degreasing cloth includes a ground thread woven on a first surface, that forms a plurality of closely-spaced holes, and a plurality of pile threads of a predetermined length extending from the first surface. Each of the pile threads is inserted and bound to the ground thread and comprises a loop. The thickness of the ground thread is substantially thicker than the thickness of the pile thread. The ground thread forms a mesh. The mesh comprises a pattern of hexagonal lattice. The greasing cloth may be formed into various applications including a pot cleaner and a laundry bag. The degreasing cloth goes under tenter process to give strength and roughness.

Abstract: A heat exchanger usable with a ventilator, the heat exchanger having an improved structure so that air passing through the heat exchanger may be prevented from leaking. The heat exchanger of the general inventive concept includes a heat-exchanging element having a plurality of liners stacked in a uniformly spaced state and a plurality of spacers disposed between the liners to define air passages, and corner guides respectively coupled to corners of the heat-exchanging element. Each of the corner guides includes a guide channel forming a space to receive the corner of the heat-exchanging element so that the corner guides securely come into close contact with the heat-exchanging element, and to minimize a loosening of the corner guide due to an adhesive applied between the heat-exchanging element and the corner guide.

Abstract: An illuminated exterior decorative device for vehicles includes a decorative part and an illuminating part. The illuminating part illuminates the decorative part from behind and includes a light source and a light diffusion portion. The light source of the illuminating part is embedded in the light diffusion portion. The light diffusion portion of the illuminating part is optically transmissive, preferably transparent. The light source is disposed along the edge of the decorative part. The light source includes a plurality of light emitting device (LED). The illuminating part has substantially the same pattern as the decorative part. The decorative part may be provided as metal coating on the illuminating part.

Abstract: An illuminating rail system comprising a rail defined by an elongate rear surface and an elongate bottom surface, the rear surface attached to a wall outside the system, the bottom surface upwardly recessed to define along the rail a front panel, a rear panel, and a furrow between the front and rear panels, with an elongate illuminator retained in the furrow.

Abstract: This invention relates to a cool air supply apparatus for maintaining a homogeneity of cool air distribution in a cold-storage room includes a cool air guiding part for guiding cool air generated from a compressor to the cold-storage room and a cool air spouting part (104, 107, 109) having multiple spouting holes (104' and 109') for spouting the cool air supplied from the cool air guiding part from the walls and door of the cold-storage room.
