    摘要: This invention provides LC compositions useful as birefringent materials in electrooptic devices which exhibit zero or low negatively sloped birefringence dispersioon (e.g., exhibiting positive birefringence dispersion significantly lower than that of currently available LC compositions) or more preferably positively sloped birefringence dispersion in which birefringence of the material increases with wavelength. The invention provides compounds useful as components of LC compositions which exhibit negative birefringence where n0 is higher than ne. The compounds of this invention are dimers of LC-like compounds in which the monomers are linked to each other through a high birefringence moiety (dimerization linker). The LC monomers consist of an LC core and one or two tail groups. Preferred monomers for this invention have low birefringence in comparison to the birefringence of the monomer linking moiety. The dimers have normal positive birefringence dispersion to have birefringence that is lower in absolute value at longer wavelengths. But since they have negative birefringence, their birefringence actually increases (i.e., goes less negative) as wavelength increases.

    摘要: The invention relates to novel solid body forms of mesoprogestin 11β-[4E-(hydroxyiminomethyl)-phenyl]-17α-methoxymethyl-17β-methoxy-estra-4,9-dien-3-one (oxime J 867), particularly a highly pure and stable amorphous or highly crystalline form (ansolvate/anhydrate) of compound J 867. The invention also relates to methods for producing said novel solid body forms and to the use thereof in pharmaceutical compositions. The novel solid body forms are characterized by exhibiting a high degree of stability. The solid body forms of oxime J 867 can, in particular, be used in the area of fertility control and in hormone replacement therapy.

    摘要: An axial compact direct drive for a storage disk comprises a stator, a rotor carrying a hub for receiving storage disks and a bearing arrangement. The bearing arrangement is disposed at a radially external edge of the hub to rotatably support the hub against axial and radial movement. The rotor is electrically driven at locations in the center of the stator or at locations surrounding the stator.
