An irreversible temperature indicating paint comprises 29 wt % to 37 wt % cobalt chromite spinel, alumina, gold purple and frit, 35 wt % to 45 wt % acrylic resin and 20 wt % to 30 wt % silicone resin excluding solvent. A drawing output processor transmits original data A1 which is original electric drawing data to an order receiving unit with a tag T attached. The tear seam defines an airbag door. The first snap ring secures the upper bearing to the rotor shaft. Afterwards, a second dielectric layer is formed in the third trench. The bilateral filtering is performed before image reconstruction by producing a noise equivalent data set from the acquired projection data and then converting the bilateral filtered values back to a projection data set suitable for image reconstruction.
