    • The heat-sensitive record material, in which color images are produced by a color-forming reaction between a colorless or pale colored basic chromogenic material and a color developer, comprises a novolac-type epoxy resin or a diphenyl sulfone derivative represented by the formula (III) in the color forming reaction system.In the former case, it is preferable to use a novolac-type epoxy resin represented by the formula (I) together witha a compound represented by the formula (II) and, in the latter case, the desired effects can be obtained by using 3-dibutylamino-6-methyl-7-phenylaminofluoran as the basic chromogenic material. ##STR1## wherein X is halogen or alkyl having C.sub.1 to C.sub.5, and a is an integer of 0 to 4; and n is an integer of 0 to 20, each of R.sub.1 .about.R.sub.6 is hydrogen, halogen, C.sub.1-5 alkyl or C.sub.1-5 alkoxyl, R.sub.7 is ##STR2## R.sub.10 is hydrogen or alkyl; each of p and q is 0 or an integer of 1 to 5; each of r and s is an integer of 1 to 5; each R.sub.8 and R.sub.9 is halogen, alkyl or alkoxyl; l is 0 or 1; u is 0 or an integer of 1 to 5; and t is 0 or an integer of 1 to 4.

    • A carrying system for carrying a lead frame of a semiconductor device includes first and second carriers located on the same side of a carrier line, one carrier located above the other carrier. The first and second carriers are movable from along the carrier line, from a start point to a processing area and to an end point. The first and second carriers each include a holder for holding the lead frame on a specific end of the lead frame. By holding the lead frame on the same side of the carrier line and at a specific end of the lead frame, holding position deviation is minimized.
    • 用于承载半导体器件的引线框的承载系统包括位于载体线的同一侧的第一和第二载体,位于另一个载体上方的一个载体。 第一和第二载体可以沿着载体线从起点移动到处理区域和终点。 第一和第二载体各自包括用于将引线框架保持在引线框架的特定端部上的保持器。 通过将引线框架保持在载体线的同一侧并且在引线框架的特定端部处,保持位置偏差被最小化。
