    摘要： Provided are a thermoplastic composite for an impact modifier and a method for preparing the same. More particularly, the thermoplastic composite includes a polycarbonate resin including carbon nanotube and cyclic butylene terephthalate impregnated into a fiber mat. The thermoplastic composite is prepared by uniformly coating a polycarbonate resin including carbon nanotube and cyclic butylene terephthalate on a fiber mat and heating to melt the resin, so that the melt resin is impregnated into the fiber mat. With superior mechanical strength, conductivity, electromagnetic shielding property and coating property, the disclosed thermoplastic composite may replace the currently used steel-based impact modifiers such as bumper back beams, front-end module carriers, door side impact bars, or the like.

    摘要： A jig for the batch production of optical communication apparatuses includes a jig body whose upper surface is provided with a plurality of U-shaped recesses arranged in a matrix array to receive silicon bases each carrying optical devices and a plurality of vacuum holes vertically formed through the jig body, to communication with the respective bottom surfaces of the U-shaped recesses. The silicon bases received by the U-shaped recesses are held onto the bottom surfaces thereof when a vacuum is applied thereto through the vacuum holes. A method using the jig enables batch production by simultaneously processing many silicon bases.

    摘要： A color image forming system including a photosensitive drum, a charger which charges the photosensitive drum, and a laser scanning unit which is installed below the photosensitive drum and radiates light onto the charged photosensitive drum, to form an electrostatic latent image. The system further includes a plurality of developing units with toner of at least four colors such as yellow, magenta, cyan, and black, arranged at different heights along the outer surface of the photosensitive drum to develop the electrostatic latent image with the toner when a developing roller installed in each of the developing units is maintained at a developing gap with the photosensitive drum. A transfer unit transfers the developed image onto a piece of paper, and a fusing unit is installed above the photosensitive drum and fuses the transferred image onto the piece of paper. The developing units may be arranged in the order of magenta, cyan, yellow, and black.
