Autodeposited coatings useful for protecting metal surfaces and in production of rubber-to-metal composites are obtained by curing adducts based on epoxy resins which are adhered to the metal surface. The truncation-compensated emission data then is used to generate an attenuation map for correcting a reconstructed emission image for effects of attenuation. A tension adjustment screw is operated to adjust tension applied to the snappy member, which can be visually observed using the scale. The dies have integrated circuitry and a plurality of bond-pads electrically coupled to the integrated circuitry. A level sensor detects inclination of the projected plane deviated from the reference plane and outputs an adjustment signal.
