| 摘要 | PURPOSE:To enable the measurement of the maximum value (or minumum value) of temperature without necessitating a power source ordinarily, by converting a temperature into a mechanical position, by memorizing the maximum value (or minimum value) of the temperature as the mechanical position, and by converting same into an electric signal as occasion calls. CONSTITUTION:A temperature-position converter 1 is deformed by a temperature applied thereto, and thereby a configuration memory alloy 2 is deformed. The deformation of the configuration memory alloy 2 is left as it is at a normal temperature even when an applied force is removed. A position-electricity converter 3 outputs an electric signal proportional to the deformation of the configuration memory alloy 2. In this way, the configuration memory alloy 2 maintains the maximum displacement given thereto, and the output of the position- electricity converter 3 is the electric signal propotional to said displacement. Since the highest temperature (or lowest temperature) is thus memorized in the displacement, a power source needs to be impressed only when the electric signal is required. So as to eliminate a memorized value, the configuration memory alloy 2 is heated by a heating body 4, and thereby the displacement can be eliminated. | ||||||
