  • Patent number: 6416826
    Abstract: A liquid crystal display element includes a cholesteric phase liquid crystal component and a space holding member held within a pair of substrates, wherein at least one of which is transparent. The liquid crystal component is a chiral-nematic liquid crystal material containing a liquid crystal pyrimidine compound having fluorine in the molecule, liquid crystal diphenylacetylene having fluorine in the molecule, and a chiral component. The liquid crystal component may also contain a liquid crystal phenylcyclohexane compound, a liquid crystal cyanobiphenyl compound, and a liquid crystal alkenyl compound. In the present invention, characteristics such as color purity and reflectivity are improved, contrast is increased, and the drive voltage can be reduced by including in the nematic liquid crystal component a liquid crystal pyrimidine compound having fluorine within the molecule, and a liquid crystal diphenylacetylene compound containing fluorine within the molecule.

  • Patent number: 5380745
    Abstract: A medicinal composition comprising a practically water-insoluble anthelmintic compound such as PF1022 substance, which is a cyclic depsipeptide compound, as an active ingredient, and one or more compounds selected from either or both of nonionic surfactants and fats and oils, optionally together with one or more aqueous solvents, wherein the total content of the additives is adjusted to not less than 1 part by weight, preferably from 5 to 50 parts by weight, based on the anthelmintic compound. This composition makes it possible to elevate water-solubility of the anthelmintic comopund and thus enhance its anthelmintic effect.
