An elevator system includes multiple elevator cars within a hoistway. The metal last layer is formed over the dielectric layer, and the metal last layer has first and second locations that are spaced apart from each other. A c+ axis vector indicating a <0001> axial direction of the base tilts toward an m-axis of the group-III nitride semiconductor at an angle of not less than 63 degrees and less than 80 degrees with respect to a vector indicating a direction of an axis normal to the semipolar surface. The sensor holding plate includes a fixing portion for fixing the sensor holding plate to the second member, a sensor holding member for holding the sensor substrate, and a plurality of arm portions provided in the relative movement direction with the sensor holding member in-between and extending from the fixing portion to constitute a cantilever. The aliphatic polyether polyol has a nominal functionality of from 2 to 4. Note that the probability distribution specifies the probability that the resampled signal would be sampled at specific quantization levels.
