With input compensation-type differential scanning calorimeters of the related art, the power supplied fluctuated even with non-endothermic reference materials, and the reference material side temperature therefore also fluctuated. The shaft, which comprises a magnetostrictive element extending therealong, is coupled with the fuel quality sensor. A second window is provided for spatially inserting anchors for the object, where each anchor specifies a desired characteristic of the object, such as a pose of a face. The method and apparatus provide a simple, efficient, cost effective and reliable means for applying a plaster-like coating to the exposed decorative surface of a workpiece for use on a commercial scale in the construction industry. If the received information shows failure of the temperature control, the gate terminal output a warning.
