    • A silver halide color photographic material comprising a support having coated thereon at least one silver halide emulsion layer, the silver halide color photographic material containing a photographic cyan dye forming coupler represented by the following general formula (I): ##STR1## wherein R.sub.1 represents an aliphatic group, an aromatic group, heterocyclic group or a substituted amino group; R.sub.2 and R.sub.3, which may be the same or different, each represents an aliphatic group, an aromatic group or a heterocyclic group, or R.sub.2 and R.sub.3 may combine with each other to form a ring; and X represents a group capable of beiing released upon an oxidative coupling with a developing agent (including a hydrogen atom).The photographic cyan dye forming coupler has a high color forming rate and provides a high maximum color density even when a color developing solution which does not contain benzyl alcohol is used, and exhibits substantially no reduction in color density in the case of processing in a bleaching solution having a weak oxidation power or an exhausted bleaching solution.The silver halide color photographic material containing the photographic cyan dye forming coupler can provide color images having excellent fastness and color reproducibility and less stain in white background area.

    • PLCC (Plastic Leaded Chip Carrier) for a LSI having protuberances on the bottom along its lateral side, is provided with interconnectors between leg portions of adjacent protuberances. Each interconnector is a swelling from the bottom surface of the main body of PLCC to fill the gap, i.e. a channel, between the protuberances. The height of the filling, namely the height of the interconnector, is lower than that of prior art protuberance to leave some space. This space, a channel, serves as a duct for solvent to flow therein smoothly to and from the narrow gap between the soldered lead and the top of the protuberance and is located adjoining this narrow gap. Therefore, the undesirably remaining flux in this narrow gap is perfectly removed by this smooth flow of the solvent. The leg portion of the protuberance is strengthened by the interconnector so that the occurrence of a crack of the protuberance when the moled PLCC is ejected from the molding cavities is considerably reduced. The structure, using the interconnector, can also avoid using a slanted protuberance having a sharp top which is likely to hurt the fingers of a PLCC handler, or which has too narrow a bottom as a channel for solvent to smoothly flow.
    • 用于具有沿着其侧面的底部突起的LSI的PLCC(塑料引线芯片载体)在相邻突起的腿部之间设置有互连器。 每个互连器是从PLCC的主体的底表面膨胀以填充突起之间的间隙,即通道。 填充物的高度,即互连器的高度,低于现有技术的突起以留下一些空间。 这个空间,一个通道,用作溶剂的流通道,平滑地流到和焊接引线与凸起顶部之间的窄间隙,并且位于邻近该窄间隙处。 因此,通过溶剂的这种平滑流动,可以完全去除在该狭窄间隙中不期望的剩余通量。 突起的腿部通过互连器被加强,使得当从模制腔中排出弯曲的PLCC时突起的裂纹的发生显着减少。 使用互连器的结构也可以避免使用具有尖锐顶部的倾斜突起,该倾斜突起可能伤害PLCC处理器的指状物,或者具有太窄的底部作为溶剂平滑流动的通道。
