A method and apparatus for making a nut having a first end, a second end, and defining an orifice extending between the first end and the second end. Among the plurality of circuit cells, one or more circuit cells at least in the vicinity of an end portion on the first chip side are arranged having a steplike shift in a direction apart from the first chip side with decreasing distance from the center portion to the end portion on the first chip side. The first and second temperature-dependent voltages varying according to a temperature and the third temperature-dependent voltage is constant regardless of variation of the temperature.
