  • Patent number: 6807730
    Abstract: A pad structure for a semiconductor package is provided by forming solder lands at predetermined locations on a printed circuit board. First circular pad portions are formed protruding laterally from upper surfaces of the solder lands. Second circular pad portions are formed protruding laterally from other lateral sides of the pads. The leads are secured to the pads of the semiconductor package so that, when the first and second circular pad portions are pushed laterally, the circular pad portions do not contact each other, thereby preventing short circuits.

  • Publication number: 20010043880
    Abstract: The thermal conductivity of the alloy of the invention can achieve 146 W/m·K, an increase of 45% compared with that of common aluminum die casting alloy-ADC12. The casting defects like shrinkage cavity, micro-porosity and amount of dross also become much less than those of pure aluminum. Further, the fluidity and mold erosion resistance of this alloy is also better than that of pure aluminum and almost equivalent to that of ADC12. When the aluminum die casting alloy of the invention is applied to a heat sink, the thermal resistance is even lower than that of ADC12 and 1070 pure aluminum.

  • Patent number: 6023298
    Abstract: A current frame containing a multiplicity of current block signals is predicted based on a previous frame by employing an apparatus which produces a predicted current block signal corresponding to each of the current block signals. The apparatus first calculates a correlation factor depicting an improved correlation between the current block signal and a corresponding predicted block signal selected from the previous frame based on an estimation of the motion between the current and the previous frames. Once the correlation factor is computed, the predicted current block signal is determined based on the correlation factor and the current and the predicted block signals.

  • Patent number: 5781249
    Abstract: A motion vector detecting method determines a motion vector of a search block included in a search frame of a video signal by using motion vectors of processed neighboring blocks, wherein the search frame is divided into a multiplicity of blocks which include a set of processed blocks whose motion vectors have been determined, and the set of processed blocks contain the processed neighboring blocks which are neighboring blocks of the search block, by: (a) selecting an X-vector and an Y-vector among the motion vectors of the processed neighboring blocks, wherein the X-vector is a vector which is most similar to a horizontal vector the and the Y-vector is a vector which is most similar to a vertical vector, to thereby provide a group of candidate vectors which include the X-vector, the Y-vector and a 0 vector; (b) deciding a candidate motion vector among the group of candidate vectors; and (c) providing the candidate motion vector as the motion vector of the search block in case a distortion between the search

  • Patent number: 4945264
    Abstract: An interface control circuit comprising a buffer, an inverter, an OR gate and delay means. The interface control circuit can be utilized in digital systems for communication handshaking such that a buffer output current will actively flow through line stray capacitance thereby greatly reducing the rise time from a LOW state to a HIGH state, or charges in the line stray capacitance will actively discharge through the buffer means if negative logic mode is used thereby enabling a great reduction in fall time, therefore a much faster and efficient digital system can be obtained through the use of the invention.
