Abstract: A process for forming an inorganic material layer pattern on a substrate. The process includes the steps of transferring an inorganic powder dispersed paste layer supported on a support film to the surface of the substrate to form the inorganic powder dispersed paste layer on the substrate; forming a resist film on the inorganic powder dispersed paste layer transferred to the surface of the substrate; exposing the resist film to light through a mask to form a latent image of a resist pattern; developing the exposed resist film to form the resist pattern; etching exposed portions of the inorganic powder dispersed paste layer to form an inorganic powder dispersed paste layer pattern corresponding to the resist pattern; and baking the pattern to form an inorganic material layer pattern.

Abstract: Liquid mobility is judged by the steps of filling the specimen in a specimen chamber formed in a specimen bed made of a transparent material just up to the level of the upper surface of the specimen bed, of pressing a liquid-absorbent material keeper for keeping a liquid-absorbent material horizontally to make the liquid-absorbent material contact with the specimen bed from the upper side of the specimen chamber, and of continuously detecting an intensity of a scattered light coming from the specimen in the specimen chamber with an optical detector consisting of a light emitting source and a light receiver and being disposed on the side of the lower surface of the specimen bed while the liquid-absorbent material is forced to contact the specimen bed. The liquid mobility is grasped in a short period of time.
