Disclosed is a method of generating a reference frame of a video CODEC for implementing motion compensation through motion estimation. The present invention is to increase compression efficiency by additionally creating various reference frames applied to an intentional motion blur and a deblur filtering, and selecting reference frame having small residual frame data during execution of the motion estimation as final reference frames among original reference frames and various reference frames additionally created.

Disclosed are structure for inlaying precious metal in and outer peripheral surface of a ring and method for manufacturing a ring inlaid with precious metal in an outer peripheral surface. The ring includes a annular blank obtained by compressing a powdered mixture including 80 to 85 weight percent of tungsten carbide in a mold by means of a hydraulic press, and a precious metal inlaid in an outer peripheral surface of the annular blank after sintering the annular blank. An annular groove is formed at an outer peripheral surface of the annular blank, in which the annular groove is defined by sidewalls, which are inwardly inclined in a downward direction, and a bottom wall. Inclined slots having a gradient identical to that of the inclined sidewalls are formed at both lower edge portions of the annular groove, in which the lower edge potions are defined between the bottom wall and the inclined sidewalls. The precious metal is inlaid in the annular groove and the inclined slots in such a manner that an upper surface of the precious metal and the outer peripheral surface of the annular blank is the same level.

Disclosed are a jig and a method for forming a satin surface on an outer peripheral surface of a ring made of a rigid material by processing the outer peripheral surface of the ring using a diamond bite in a state in which inner and outer peripheral surfaces of the ring do not represent a perfect roundness and a center of the outer peripheral surface of the ring is offset from that of the inner peripheral surface of the ring. The method includes the steps of supporting both sides of the ring while rotating the ring, and processing the outer peripheral surface of the ring by using the diamond bite.

The inventors have discovered that aerodynamic forces contribute to disk fluttering. If the flow of air about these disk surfaces is unstable, the resulting aerodynamic forces can mechanically excite the disk surfaces, causing fluttering. The invention includes media enclosures constraining such aerodynamic effects, methods of making disk drives with these enclosures, the disk drives. This includes disk drives of at most 13 millimeters in height.

摘要:
A compression encoding method which, when performing data conversion using the fact that when data is converted into frequency components, the human eye is sensitive to components close to low frequency components and insensitive to components close to high frequency components, configures a filter in which importance is placed on DC data and its adjacent filter coefficients, calculates the cost for a conversion block which has undergone conversion and quantization, which is required for the data removal of compression encoding using the filter, determines data targets to be removed using the calculated cost and set reference values, and removes the corresponding data, thereby reducing the amount of data to be compressed and therefore increasing compression efficiency without influencing image quality.
