摘要:
This polyimide film is superior in heat resistance, rigidity and high frequency properties, is free of inconveniences due to curling even when various functional layers are laminated by heating, and is preferable as a substrate film superior in thermal degradation stability for electronic parts. This polyimide film has a planar orientation coefficient of 0.79-0.89 as measured by an X-ray diffraction method, a difference in the surface planar orientation degree between one surface thereof and the other surface thereof of not more than 2 and a curling degree of not more than 5%, which is obtained by imidation of a polyimide precursor film having a particular imidation rate.

摘要:
A film thickness measurement apparatus includes: an ECT sensor for measuring a film thickness of a thermal barrier coating formed on a turbine blade; a storage unit for storing a measurement point on the turbine blade which is a point where the film thickness of the thermal barrier coating is measured; a laser displacement meter for measuring a shape of the turbine blade; a measurement position calculation unit for calculating an actual measurement point suitable for actual film thickness measurement using the ECT sensor, based on the shape of the turbine blade measured by the laser displacement meter and the measurement point on the turbine blade stored in the storage unit; and an arm drive unit for driving the ECT sensor to adjust a measurement position of the ECT sensor based on the actual measurement point calculated by the measurement position calculation unit.
