Abstract: The present invention relates to a method for manufacturing a plate or a film which manufactures a plate by injecting a resin in a microchannel structure, wherein channels with a width of w and a depth of h are arranged at a distance of p on a base plate with a thickness of t. In the microchannel structure, the w is selected by the diameter size of a microball to be formed on the surface of the plate and satisfies a relation of h>=2w and p=(w+channel wall thickness), and the channel wall thickness is selected by a distance between the microballs. Additionally, the method for manufacturing the plate or film controls the pressure of the resin injected to the inner space of the channel so that microball shapes are formed on the surface of the plate at regular distances. The present invention has an effect of manufacturing the plate or film with light scattering properties and liquid contact properties different from the existing product by using the resin. The microball structure is shown on a free surface according to physical properties without artificially reproducing the surface shape of a mold or die, thereby having an effect of simplifying the molding of a complex polymer surface structure.

Furthermore, the present invention is effective in the membrane cleaning process such as backwash; has excellent filtration efficiency which significantly improves the water permeability, and at the same time has excellent rejection coefficient.

Abstract: PURPOSE: A road information displaying device for reverse-transferring hybrid energy is provided to reverse-transfer electricity produced by solar heat, wind power, and geothermal heat, thereby reducing cost and economizing the use of electricity. CONSTITUTION: A road information displaying device for reverse-transferring hybrid energy comprises a plurality of display panels(140), a power supply device(150), a control unit(160), and a reverse-transferring device. The power supply device produces electricity using a solar panel(170), a wind turbine(180), or a geothermal rod(190) during the LED(Light Emitting Diode) light out of the display panel. The reverse-transferring device converts the produced energy into electricity and reverse-transfers the converted electricity to a common use electric-point system(E).
