Abstract:
Disclosed is an elementally mixed Al—Cu—Zn base powder blend for a sintered Al base alloy. The powder blend includes more than 5.6 wt % and less than 9 wt % Cu, 1˜5 wt % Zn, and a balance Al. With the powder blend, an article of a sintered Al base alloy having higher wear resistance as well as higher tensile strength can be fabricated.
Abstract:
An apparatus and method are provided for compensating a block error in an image frame. This may include a video codec decoder for decoding an inputted image frame, and outputting a decoded image frame. An error concealment block may detect an error-generated block in the decoded image frame and compensate the detected error block through a median filter, and output the compensated image frame.
Abstract:
The vacuum insulator in accordance with the present invention comprises glass white wool body which density is 0.1˜0.5 g/cm3 in density and is below 0.0023 kcal/mh° C. in thermal conductivity, and a non permeable container surrounding the body in which the pressure is between 10−6 ˜10−1 torr. The vacuum insulator is fabricated by piling up glass white wool, thermal-pressutizing the piled glass white wool to form a body of 0.1˜0.5 g/cm3 in density wherein the pressurizing is done at 0.007˜1.5 kg/cm2 and under 20° C. for more than 10 minutes, putting the body in the non-permeable container, and producing a vacuum in the container.
