Title: Image processing method
Inventor: NEISAN M MORONY
IPC: H04N1/405
Filed: 2001-04-19
Abstract: PROBLEM TO BE SOLVED: To form effectively a compressed image including half-tone. SOLUTION: A first base coefficient set which is formed by forward transformation (e.g. discrete type cosine transformation) of space image data is combined with a second base coefficient set corresponding to frequency region transformation of half-tone texture which is previously determined (step 480). The compressed image data are formed by quantization (step 440) and entropy coding (step 450) of the combined base coefficient. A source space image including the previously determined half-tone texture is reconstructed by an inverse transformation which is executed successively after compression release process. As a result, execution of half-tone process in a space region can be saved after a compression process.

Title: Oil-impregnated sintered bearing
Inventor: NISHIO KENJI
IPC: F16C33/10
Filed: 2001-04-19
Abstract: PROBLEM TO BE SOLVED: To provide an oil-impregnated sintered bearing capable of avoiding a decrease in efficiency of rotation even at low temperatures, during or immediately after startup, and thus prolonging the service life of a rotating shaft and that of the bearing. SOLUTION: A resin sliding portion 22 made from a nonporous fluororesin is formed on a circumferential portion of the inner peripheral surface 21 of the bearing 15 so that the rotating shaft 14 slides while abutting the resin sliding portion 22. The possibility of lubricating oil being pressed into the inner peripheral surface 21 by the rotating shaft 14 is thus eliminated. Even without lubricating oil, this arrangement has reduced sliding resistance between the bearing 15 and the rotating shaft 14, as compared with an arrangement wherein the rotating shaft 14 and a metallic member slide against each other.  Further, the thickness of the resin sliding portion 22 is set at approximately 20% or less of the wall thickness of the bearing 15, thus avoiding a decrease in inside diameter of the bearing 15 caused by the shrinkage of the resin sliding portion 22 when the bearing 15 is at low temperatures.
