A thermal printhead includes a substrate, a glaze layer, a heating resistor, an electrode for energizing the heating resistor, the electrode being mainly composed of Au, and a protective film covering the heating resistor and the electrode. A cross-sectional shape of the shower sink includes a bottom wall having a large curvature, a first sidewall rising substantially vertically from one of opposite ends of the bottom wall, and a second sidewall rising from the other end of the bottom wall and having a curvature smaller than that of the bottom wall. The pointing device also having at least one movement transmission element disposed between the support element and the load to point the load relative to the support element. The trackable devices can be incorporated into the weave of a woven cloth or the matrix of a polymer member. For example, the relation is between command \u201cJump\u201d and movement of jumping. Vaccines comprising the genetically modified virus and polynucleotides are also provided.
