Abstract: A coating unit, an aging unit, and a solvent substituting unit are adjacently disposed. The waiting time period after a wafer is loaded to the coating unit until the coating process of the coating process is started, is adjusted so that the staying time period of the wafer in the coating unit becomes longer than the staying time period of the wafer in the aging unit and the staying time period of the wafer in the solvent substituting unit (whichever longer). The staying time period of the wafer in the coating unit is designated as a rate determiner. Thus, after the coating solution is coated to the wafer, the wafer is quickly conveyed to the next process. Consequently, since the solvent can be suppressed from evaporating, an excellent thin film can be obtained.

Abstract: A method for exposing photo-sensitive printing plates comprises applying a patterned coating to the printing plate to form a mask.

In a detailed embodiment an abradable coating having a metal volume fraction in the range of from 0.3 to 0.5 is applied to an inner circumference of a stator for a gas turbine engine compressor. The eddy current probe is positioned by a manipulator. A distance separating the probe and a surface of the coating is measured using a frequency above one megahertz (MHz). The thickness of the coating is measured by determining the rolloff frequency for the coating's complex impedance. The coating density is determined by its complex impedance at a characteristic frequency below four MHz. The density can be used as an indication of the performance of the coating with respect to abradability and the erosion resistance. The measurements may also be applied as a post-process quality control technique.

Abstract: In the present invention, a waste solution and a exhaust gas are guided together from a drain cup DC into a storing means through common discharge means. Naturally, the gas-liquid separation is performed within the storing means in place of performing the gas-liquid separation within the drain cup DC.

Further, since a minimum amount of the exhaust gas is kept discharged even during non-operation of the coating apparatus by using an exhaust gas damper whose degree of opening can be controlled, the waste solution stored in the storing means is prevented from being solidified.

Abstract: A body of a vehicle, that is supported by a carrier or conveyor is rotated about a rotational axis extending in an approximately horizontal direction of the carrier or conveyor. When the body is supported in a normally standing position with its roof at the top of the body and its floor at the bottom thereof, the center of gravity of a rotary member containing the body is set to be at a position underneath the rotational axis in a vertically extending plane containing the rotational axis. The body is locked by a clamping unit so as to prevent rotation when the body is coated in the coating station. In the drying station, the locking by the clamping unit is released and the body is then displaced at a given angle so as to cause rotation on account of inertia on the basis of its own weight. After the drying station, the forcible rotation is shifted to free rotation which in turn is caused to be converged into a rest or normally standing position.
