Leggings with knee pads and patches protect babies when they crawl or fall on hard or abrasive surfaces. It is checked for a normally sensed image obtained by normal image sensing whether each pixel data is data at the pixel position corresponding to dust. The head is then heated far above the decomposition temperature of the plastic still remaining, and the gaseous products thereby occurring are discharged. The surface adjoining the elevation in that direction has an extent in that direction such that an injection jet injected at the latest possible time point impinges onto the surface and is distributed both in the elevation direction and in the recess edge direction. Devices that include the transistors and methods for making the transistors are also disclosed.
