A double pipe and a heat exchanger having the same are provided. The double pipe including an outer pipe and an inner pipe formed within the outer pipe includes: a plurality of barrier ribs formed in a length direction and disposed at a predetermined distance in a circumferential direction between the outer pipe and the inner pipe; and a plurality of protruding portions formed at positions corresponding to each of the plurality of barrier ribs and protruded in a center direction and formed in a length direction of the inner pipe from an inner circumferential surface of the inner pipe. Therefore, by improving heat exchange efficiency by the heat exchanger having the double pipe, cooling efficiency of a cooling system can be improved.

A field emission backlight unit for a liquid crystal display (LCD) includes: a lower substrate; first electrodes and second electrodes alternately formed in parallel lines on the lower substrate; emitters disposed on at least the first electrodes; an upper substrate spaced apart from the lower substrate by a predetermined distance such that the upper and lower substrates face each other; a third electrode formed on a bottom surface of the upper substrate; and a fluorescent layer formed on the third electrode. Since the backlight unit has a triode-type field emission structure, field emission is very stable. Since the first electrodes and the second electrodes are formed in the same plane, brightness uniformity is improved and manufacturing processes are simplified. If the emitters are disposed on both the first electrodes and the second electrodes, and a cathode voltage and a gate voltage are alternately applied to the first electrodes and second electrodes, the lifespan and brightness of the emitters can be improved. The above advantages are also achieved as a result of the method of driving the backlight unit and the method of manufacturing the lower panel thereof.

A three-dimensional measurement system using an IGPS includes a rescale bar having linear scales thereon, a linear encoder for measuring an absolute length within which the linear encoder moves on the rescale bar, a plurality of optical transmitters that radiates pan beams, and a vector bar having one end attached to the linear encoder, and having a receiver to detect the pan beams radiated from the optical transmitters, the vector bar acquiring coordinates of two points where the vector bar moves by using the receiver, and measuring a relative length from the coordinates. A ratio between the absolute length and the relative length is applied in rescaling an actual distance between two positions to be measured.
