    摘要: The present invention provides a method for producing ceramic fine particles comprising the steps of supplying gaseous starting materials or starting material droplets to a reaction space arranged in an annular portion between inner and outer cylinders of a coaxial, double-cylinder reaction apparatus, the reaction apparatus having a stationary outer cylinder and a rotatable inner cylinder; and subjecting the gaseous starting materials or the starting material droplets to reaction in the reaction space while rotating the inner cylinder. Also, the present invention provides a production apparatus used therefor. In the present invention, by utilizing the Taylor vortex flow as the flow for a CVD reaction field or a pyrolytic reaction field, uniform ceramic fine particles can be produced at a high yield because of an even temperature distribution, and an even concentration distribution of the reaction gases or an even concentration distribution of the droplet number in the vortex flow, and residence time of the resulting fine particles locked in the vortex flow.

    摘要: A coating apparatus 10 is disclosed, which comprises a slot 18 and a chamber 17 formed upstream the slot 18 such as to distribute a coating liquid 12 in a coating width direction. The coating liquid is coated such that it is pressed against a web 11 as it is discharged from the slot. The slot gap H of the slot and the slot gap error .DELTA.H in the coating width direction satisfies a relation .DELTA.H/H.ltoreq.0.05 and the pressure loss Pb of the coating liquid flowing in the chamber in the coating width direction, and the pressure loss Ps flowing in the slot satisfies a relation as follows. Pb/Ps.ltoreq.0.15
