Title: Video signal quantizing method
Inventor: MASUNAGA MAKOTO
IPC: H04N5/76
Filed: 1989-03-30
Abstract: PURPOSE:To improve the gradation expressing capability when an output is given to a printer by compressing a level near a white level when a video signal subjected to gamma processing is processed linearly. CONSTITUTION:The gamma of a video signal to be given from 0 percentage level to 100 percentage level of a luminance signal is subjected to a complete linear processing and d='0' and c='121' are assigned to each level. On the other hand, the luminance signal from 100% level to 200% level outputs without applying linear processing to a data applied with upsilon given at first as it is. That is, the signal is outputted with the tilt of x/5+alpha, then a data (b) corresponding to the luminance 200% is set as b='255'. Thus, when a video signal having a bright part in the background is printed out, the whitening of the background is effectively prevented without making the part expressed substantially dark.

Title: Alloy for ic lead frame excellent in stress corrosion cracking resistance
Inventor: SAKAMOTO DAIJI
IPC: C22C38/00
Filed: 1988-04-01
Abstract: PURPOSE:To manufacture the title alloy excellent in plating suitability and solderability by reducing residual strain existing in an alloy without adding corrosion resistance-improving elements. CONSTITUTION:This alloy for IC lead frame has a composition consisting of, by weight, <=0.05% C, 0.05-0.5% Si, 0.1-1.0% Mn, 35-55% Ni, and the balance Fe and also has a structure in which the half-width of the X-ray diffraction peak in tie (311) crystal plane at the rolling surface is regulated to 0.65-0.85. The above halt-width is used as a semiquantitative index to the residual strain existing in the alloy, and sensitivity to stress corrosion cracking can be blunted by reducing the value of the above half-width. This value is limited to 0.650-0.85 because the mechanical strength of the alloy is deteriorated, on the contrary, when the value is too small and, as a result, the alloy is made unsuitable for IC lead. Since Sn+Pb, Mo, etc., are not added to the above alloy, plating suitability, mechanical strength, etc., are not deteriorated.
