Abstract: PURPOSE:To allow black and white display without coloration by forming oriented films of an inorg. insulator which are reverse in inclination direction from each other on the opposite surfaces of a pair of substrates and specifying the thickness of the liquid crystal layer thereof to a prescribed range. CONSTITUTION:Two sheets of the glass substrates 11 constituted by coating the surfaces of transparent electrodes 14 with inorg. insulating films 13 having a high dielectric constant, then forming the oriented films 12 of SiO formed by a diagonal vapor deposition method are so combined that the respective oblique oriented layers of the SiO are reverse inclined. In addition, the liquid crystal cell is so constituted that the spacing between the oblique oriented layers of the SiO attains 1.5 to 4.0mu. A liquid crystal compsn. mixture contg. a ferroelectric liquid crystal of an ester system which is liable to be oriented in the oblique oriented layer of the SiO is injected in this cell. Two sheets of polarizing plates are disposed on the upper and lower glass substrates in such a manner that the transmittance is lowest when a positive or negative voltage is impressed to the element. The ferroelectric liquid crystal element is thus obtd. The black and white display which is substantially free from the coloration is possible in this way.

Abstract: PURPOSE:To facilitate the production of the titled microspheres useful in the production of sintered microspheres, etc., by disintegrating a melt-blend of resin A and component B incompatible with resin A by immersion in a solvent which is a poor solvent for resin A but is a good solvent for component B and separating particles of resin A.

This melt blend is cooled directly or after it is heated at a temperature higher than any of the melting points of resin A and component B within 2hr. The obtained cooled blend is disintegrated by immersion in a solvent S which is a poor solvent for resin A but is a good solvent for component B (e.g., water) to obtain a suspension comprising solvent S in which component B is dissolved and particles of resin A are dispersed. The particles of resin A are separated from the dispersion. In this way, it is possible to obtain the titled microspheres of a particle diameter of 0.01-100mu suitable for use in, for example, sintered microfilters, fluidized bed coatings, electrostatic coatings, sol coatings, solid lubricants, and cosmetic additives.
