Title: Method for calibrating thickness measuring device
Inventor: ISHIKAWA HIROTOSHI
IPC: G01B21/08
Filed: 1987-12-14
Abstract: PURPOSE:To remove the effect of a gap, by performing zero measurement by upper and lower detection heads at the time of calibration and giving a definite gap to again perform zero measurement to calculate the detection characteristic to the gap and correcting the measured value on the basis of the detection characteristic value at the time of measurement. CONSTITUTION:At first, the interval between an upper detection head 2 and a lower detection head 3 is measured by the gap sensor 5 mounted on the base 301 of the lower detection head 3. Next, zero measurement is performed in a usual state and in such a state that the head interval is widened by definite quantity as compared with the usual state to calculate a characteristic in a Z-direction. The gap Z between the upper and lower detection heads 2, 3 imparts different values like C1, C2 at the time of the first calibration and at the time of this calibration, and an error (d) is generated between an initial gap Z0 and the value by the zero measurement when the lower head 3 is lowed, for example, by DELTAZ as shown a chart. Therefore, a correction signal dm is calculated from the gap measured value Zm between the heads 2, 3 and a newly formed Z-direction characteristic curve C2 at the time of measurement by the gap sensor 5 and the value detected by a sensor coil 304 is corrected using the signal dm.

Abstract: PURPOSE: To always maintain the inside of a working chamber in the clean condition by limiting oil staying between a drive shaft and a partition wall by difference of gas pressure between a drive chamber and a working chamber. CONSTITUTION: The discharge pressure of a pump 23 is adjusted, so that the difference of gas pressure corresponding to the surface tension of lubricating oil 26 at a level A is generated between the backward space 19 of a piston working chamber and a piston drive chamber 15.
