Abstract:
A stress-reduced circuit board includes an insulating substrate, and first and second electrically conductive layers which are stacked one upon the other, and which respectively have peripheral marginal regions that are configured in a stepped arrangement. The first electrically conductive layer is configured to have an area dimension larger than that of the second electrically conductive layer and a thickness not greater than that of the second electrically conductive layer so as to minimize stress caused by a difference in coefficients of thermal expansion between the insulating substrate and the first and second electrically conductive layers.
Abstract:
A method for encoding a frame of visual data which includes the steps of encoding an original full resolution frame, storing coded data for the encoded full resolution frame, reconstructing and storing encoded full resolution frame, downsampling the original full resolution frame to render it a reduced spatial resolution frame, encoding the reduced spatial resolution frame, storing coded data for the reduced spatial resolution frame, reconstructing and storing the reduced spatial resolution frame, upsampling and storing the reconstructed reduced spatial resolution frame, comparing a characteristic in the reconstructed full resolution frame with said characteristic in the original full resolution frame to determine the deviation of the reconstructed full resolution frame from the original full resolution frame with respect to said characteristic, comparing said characteristic in the upsampled reconstructed spatial reduced resolution frame with said characteristic in the original full resolution frame to determine the deviation of the upsampled reconstructed spatial reduced resolution frame from the original full resolution frame with respect to said characteristic, selecting the frame with the lesser deviation from the original full resolution frame with respect to said characteristic, and outputting the coded data corresponding to the frame with the lesser deviation from the original full resolution frame with respect to said characteristic to the bitstream.

Abstract:
A method for enhancing strength and hardness of powder metallurgy stainless steels comprises steps of fabricating a stainless steel powder into a green compact; placing the green compact in a reducing environment and maintaining the green compact at a sintering temperature to form a sintered body; and placing the sintered body in a carbon-bearing atmosphere and maintaining the sintered body at a carburizing temperature below 600° C. to implant carbon atoms into the sintered body and form carburized regions in the sintered body. Thereby, the strength and hardness of powder metallurgy stainless steels can be improved. As the carburizing temperature is lower than 600° C., chromium would not react with carbon. Therefore, the strength and hardness of powder metallurgy stainless steels can be enhanced and the superior corrosion resistance is still preserved.
Abstract:
A cutter includes a cutter handle and cutter head including a main body and a plurality of curved cutting edges separately extending from a periphery of the main body. Each cutting edge has a top surface, a first side blade surface, a second side blade surface, and a bottom surface. The top surface, the first side blade surface, the second side blade surface, and the bottom surface intersect to form a front edge, a middle edge, and a back edge. The front edge, the middle edge, and the back edge cooperatively form an edge tip. A tangent of the middle edge at the edge tip intersects with the bottom surface to form a cutting angle in a range from 30° to 60°.
