Abstract: The present invention relates to a stress-free lead frame (1) for a semiconductor. The stress-free lead frame (1) is provided with a stress-relief means (15) and an interlocking means (16) at the outer periphery. The stress-relief means (15) is capable of accommodating expansion and compression while the interlocking means (16) take care of shock and vibration during handling to thereby eliminate delamination of the lead frame (10).

Abstract: A method for extracting a shape variation descriptor from image sequence data for content-based image retrieval is disclosed. The method for extracting the shape variation descriptor from image sequence data for content-based image retrieval, image sequence data representing variation of object through a plurality of frames, the method includes the steps of creating a frame including variation information and shape information by accumulating the plurality of frames, the centroid of object regions in each frame aligned; and extracting shape descriptor from the frame.

Abstract: Disclosed is an apparatus and method for controlling feed quantity and direction in a sewing machine, in which feed quantity and direction of a workpiece is controlled by a motor, thereby not only allowing various patterns to be produced by stitches made up of upper and lower threads, but also allowing a speedy sewing operation. The apparatus comprises an operator interface means for inputting the feed quantity and direction of a workpiece according to an operator's plan, a motor driving control means for outputting a motor driving control signal according to feed information on the feed quantity and direction of the workpiece inputted through the operator interface means, and a workpiece feed control means for controlling rotation direction and speed of the motor according to the motor driving control signal from the motor driving control means.

Abstract: Disclosed are an apparatus for controlling a position of an embroidery frame, which is capable of performing an accurate embroidering operation by feed backing a position error due to mutual operations of interlocking devices for driving the embroidery frame using a displacement sensor for sensing a displacement of the embroidery frame, and a method thereof. The apparatus comprises an X-axis driver, a Y-axis driver, a sensor and a controller. The X-axis driver moves the embroidery frame along an X-axis direction. The Y-axis driver moves the embroidery frame along a Y-axis direction. The sensor senses a displacement of the embroidery frame to the X-axis and Y-axis directions, and outputs electric signals corresponding to the sensed displacement. The controller generates X-axis and Y-axis drive control signals based on the electric signal from the sensor in order to control the X-axis and Y-axis drivers, respectively.

Abstract: Disclosed is an apparatus for driving a shuttle of an embroidery machine. The apparatus comprises: a rotation shaft of the shuttle; a lower shaft which transfers a driving power to the rotation shaft, so as to rotate the shuttle; a first magnet provided at the rotation shaft; and a second magnet provided at the lower shaft and corresponding to the first magnet. The first magnet has a hollow cylindrical shape so that the rotation shaft can be inserted through the first magnet while firmly holding the first magnet. The second magnet has a hollow cylindrical shape so that the lower shaft can be inserted through the second magnet while firmly holding the second magnet.

Abstract: The present invention relates to a sintered ceramic composite implant material and a fabrication method thereof. A sintered ceramic composite implant material includes an apatite matrix phase, a ceramic secondary phase located in the apatite matrix phase, a barrier layer coating the ceramic secondary phase. The secondary phase compensates for and improves the mechanical properties of the apatite matrix phase and the barrier layer restrains an interfacial reaction between the apatite matrix phase and the secondary phase.
