Abstract: When an optically anisotropic material is manufactured, an optically anisotropic liquid crystal layer with good adhesion properties and without irregular alignment is formed on a substrate. The optically anisotropic material having the optically anisotropic liquid crystal layer formed on the substrate can be manufactured by subjecting the surface of the substrate to rubbing treatment, subjecting the rubbing-treated surface to surface treatment with the hydrolysate of an alkoxysilane compound, applying a polymerizable nematic liquid crystal composition to the surface-treated surface, subjecting the applied polymerizable liquid crystal composition to alignment treatment, and subjecting the polymerizable liquid crystal composition to curing treatment while the alignment state thereof is maintained, whereby the optically anisotropic liquid crystal layer is formed.

Abstract: A simple technique for introducing a hybrid alignment or a homeotropic (vertical) alignment into liquid crystal films, which, by their nature, tend to have a horizontal alignment of liquid crystal molecules. The technique does not require special alignment films. A liquid crystal composition for forming a liquid crystal film contains a polymerizable liquid crystal compound and a hydrolysate of an alkoxysilane compound. The hydrolysate of the alkoxysilane compound contains a siloxane oligomer of which degree of polymerization is from 2 to 25. Furthermore, the alkoxysilane compound is a trialkoxysilane compound having a functional group. This liquid crystal film composition can be produced by hydrolyzing an alkoxysilane compound to obtain a hydrolysate and then uniformly mixing the hydrolysate with a polymerizable liquid crystal compound.

Abstract: After a probe control means causes a longitudinal wave probe to carry out transmission and reception, it slides a shear wave probe to the same position. The probe control means rotates the shear wave probe at each predetermined angle and rotates it 180° while causing it to carry out the transmission and the reception at each rotating position. A measured data analyzer 16 calculates the constant of texture induced anisotropy in a test piece from echo data when both the probes carry out the transmission and the reception. With this arrangement, it is possible to measure the residual stress of a material, in which both texture induced anisotropy and residual stress induced anisotropy mixedly exist with pinpoint accuracy by separating only the texture induced anisotropy from the material.
