| 20100298107 | NYLON CONVEYANCE ROLLER - The present utility model is a nylon conveyance roller used for the lifting platform loader of aircraft cargo transit wagon, wherein there is a tunnel going through the said roller for placing the axle. The tip and toe of the said roller are provided with plane structure, and the outer surface of the said roller is frosted texture. The material Nylon, designed for making the said conveyance roller, is suitable. It can increase the friction between the roller and the floor of container and container plate during cargo conveyance, making skidding conditions or noise during rotating friction unlikely. By using nylon as material, the said roller can boast good wear resistance, low noise, a slim likelihood of skidding condition, and environmental compliance. | 11-25-2010 |

| 20110039672 | FUNCTIONAL ROLL INCORPORATING A STRUCTURE OF A LATTICE-SHAPED FLUID (GAS-LIQUID) GUIDEPATH - Conventional art has a structure consisting of a roll axis incorporating a structure of fine pores, and a roll unit provided around the outer circumference of a roll axis, wherein internal pressure of the roll axis is dispersed to the roll unit to make a fluid (gas-liquid) suction action, thus reducing the pressure loss and obtaining even distribution of the fluid (gas-liquid). As such, instead of a tubular roll axis, the structure of a roll axis is made fin-shaped or groove-shaped to maximize the action surface area that works on the inner pressure of the roll axis of the roll unit. However, other problems such as inefficiency of the fluid (gas-liquid) suction action and lack of mechanical strength of the roll axis remains. To solve these problems, this invention provides a functional roll incorporating a structure of a lattice-shaped fluid (gas-liquid) guidepath made of high-density porous sheet material to activate the internal pressure of the roll axis, therein the structure of the lattice-shaped fluid (gas-liquid) guidepath, consisting of an internal pressure action space made of a cut-out portion provided on the circumference of the roll axis, and in the axis direction of the roll unit, and an internal pressure branching guidepath made of low-density porous sheet material, or a space communicating with the internal pressure action space, as well, being provided in the radial direction of the roll unit. | 02-17-2011 |
