摘要:
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.

A display device and a fabrication method thereof are provided. In a dual-link structure for a narrow bezel, first link wirings are formed on the same layer that the gate lines are formed and second link wirings are formed on the same layer that the data lines are formed. The first link wirings and the second link wirings are formed in a non-display area. Or auxiliary link wirings are further formed over the first link wirings and the second link wirings respectively. Or the first link wiring and second link wiring are divided two pieces of sub-link wirings. The sub-link wirings consisting the one link wiring are connected respectively and are formed on the different layer, whereby a defective image due to a difference in resistance between neighboring link wirings can be improved.

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. The method for manufacturing molten irons according to the present invention includes steps of reducing mixtures containing iron ores in a reduction reactor and converting the mixtures containing iron ores into reduced materials, preparing lumped carbonaceous materials containing volatile matters as a heating source for melting the reduced materials, charging the lumped carbonaceous materials into a dome-shaped upper portion of a melter-gasifier and forming a coal packed bed, preparing fine carbonaceous materials containing volatile matters as a heating source for melting the reduced materials, injecting oxygen and the fine carbonaceous materials into the coal packed bed through a tuyere installed in the melter-gasifier, charging the reduced materials into the melter-gasifier connected to the reduction reactor and manufacturing molten irons, and supplying reducing gas in the melter-gasifier made from volatile matters contained both in the lumped carbonaceous materials and the fine carbonaceous materials to the reduction reactor.
摘要:
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.
