A shift register without a feedback signal of a post-stage shift register utilizing a latch mechanism and a clock signal to control the voltage of an output of the shift register is provided. In order to provide a method for controlling a microcontroller in a control unit that better protects the verification of memories of the microcontroller against unauthorized intervention, a verification program is stored in a write-once memory area of the rewritable memory area and a service program is stored in the read-only memory area. 5 wt % Mn to port hole extrusion or port hole extrusion and drawing-elongation processing and wherein a difference in electric conductivity between individual portions in lengthwise direction of the hollow material is not more than 1. These primary color images and their primary color fragments are transformed into arrangements of points, at which laser-induced marks are produced.
