Articles exhibiting flame retardancy and heat resistance are fabricated from a composition that includes specific amounts of a poly-polysiloxane block copolymer reaction product, a flame retardant, and a reinforcing filler. The method comprises providing a calibration chart not built in the image-capture apparatus. Also provided are a tiltingangling pressure oil feed means comprising a tiltingangling directional control valve 19 for controlling a flow of pressure oil to be fed to one of the cylinders 9,10 and a selector valve 20 for selectively feeding pressure oil, which flows out of the directional control valve 19, to one of the cylinders 9,10.
