Abstract: PROBLEM TO BE SOLVED: To suppress edge drop and to improve yield by executing rolling making the coefficient of friction between the edge parts of a rolled plate and the surface of work rolls in contact with the edge parts lower than the coefficient of friction in the middle part except the edge parts. SOLUTION: A metallic plate is rolled operating a work roll shifting mechanism or a work roll crossing mechanism. Upper and lower work rolls 1, 2 are shifted in the direction of the arrow and lubricating liquid is jetted to the upper and lower work rolls 1, 2 from lubricating liquid jetting nozzles 5. Rolling is executed making the coefficients of friction between the edge parts of the rolled plate and the surfaces of the work rolls lower than the coefficients of friction in the middle parts. To change the coefficient of friction, the jetting quantities to the edge parts of the rolled plate are increased as compared with the middle parts except the edge parts. Furthermore, as means for changing the coefficient of friction, high-concentration rolling oil is jetted to the edge parts and low-concentration rolling oil to the middle parts.  In this way, the edge drop in edge part is suppressed, defects in shape are prevented and yield is improved.

Abstract: PROBLEM TO BE SOLVED: To apply an ideal input/output characteristics only for a practical luminance signal by executing only gamma correcting processing on the stage of two-channel output and performing processing for suppressing a low level only for the luminance signal prepared from the two-channel output. SOLUTION: Concerning three primary color signals of respective pixels outputted from a color separating circuit 9, a matrix circuit 10 prepares a luminance signal Y and the color difference signal of the relevant pixel through prescribed operation expression. At a low input suppression circuit 11, only the luminance signal Y from the matrix circuit 10 is amplified based on an amplification degree to be changed corresponding to the input level. The luminance signal is level-suppressed by the characteristics equivalent to a sigmoid curve at both gamma correction circuits 7 and 8 and the low input suppression circuit 11, and the gamma correction is performed so that the degradation of S/N in a dark part is prevented by suppressing the luminance level in a low luminance area but the gamma can be '1' in any area excepting for the low luminance area.  Besides, concerning both the color difference signals, ordinary gamma correction is executed by the gamma correction circuits 7 and 8.

IPC: G06T17/20
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of finite elements in number and the increase of a calculation cost by executing division through the use of only a line to be used as a boundary line at the time of dividing the finite element. SOLUTION: A design line is treated as a ridge. The ridges (design line) are discriminated to be main ridges S1-S4 for expressing the main shape of parts and a sub-ridge F1 for expressing the minute shape except it. Nodes for dividing a shell (finite) element is provided in the main ridges and, in the meantime, the node is not always generated in the sub-ridge F1. The two kinds of ridges are used so that the finite element is prevented from becoming drastically small and also the division of the finite element by uniform size is enabled. Then, only the segment judged to be used as the boundary line at the time of division into the finite element is used as a division boundary line so as to execute division into the finite element at evey area surrounded by the division boundary line.
