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.
摘要翻译：本发明提供了用作电光装置中的双折射材料的LC组合物，其显示零或低负斜率的双折射分散体（例如，显示出比当前可用的LC组合物显着低的正双折射色散）或更优选正斜率双折射色散，其中双折射材料随波长增加。本发明提供了用作LC组合物的组分的化合物，其中n0高于ne，表现出负双折射。本发明的化合物是通过高双折射部分（二聚接头）将单体彼此连接的LC样化合物的二聚体。 LC单体由LC核和一个或两个尾组组成。与单体连接部分的双折射相比，用于本发明的优选单体具有低双折射。二聚体具有正常的正双折射色散，使双折射在较长波长下的绝对值较低。但是由于它们具有负双折射，所以随着波长的增加，它们的双折射实际上增加（即，变得越来越小）。

摘要： The invention relates to chiral nonracemic liquid crystal compounds which are useful as components in liquid crystal compositions to impart high polarization to the mixture. The materials of this invention can be combined with liquid crystal host materials to impart improved properties to mixtures. Chiral nonracemic compounds of this invention can function as additives or dopants in host materials to impart chirality into an LC material. Most generally the invention provides mixtures containing one or more chiral nonracemic dopants which have a chiral nonracemic tail that is an optionally substituted α-ester γ-lactone of the formula: where * indicates a chiral carbon; R1 is a straight-chain or branched alkyl or alkenyl group wherein one or more non-neighboring carbon atoms can be replaced with an oxygen atom and wherein one or more carbons can be substituted with one or more halogens; R2 and R3, independently of one another, can be hydrogen, a halogen or a lower alkyl or alkenyl group; and X is hydrogen or a lower alkyl group. LC compounds having a chiral nonracemic tail of this general formula have large dipoles (and large spontaneous polarization (Ps)) and when doped into hosts such as achiral smectic C FLC hosts, lead to improved switching speeds of the FLC materials.

摘要： A rear-wheels transmission and suspension system, adapted for modifying a two wheeled motorcycle into a motorcycle containing two rear wheels, includes a suspension device, a rear axle and a transmission device. The suspension device includes a supporting frame longitudinally extending along the central axis of a construction frame and pivotally connected with a seat portion of the construction frame of the motorcycle for supporting the rear axle at the rear end the supporting frame while defining a transmission cavity after a rear end of the supporting frame and at a central position behind an output of said engine along the central axis of the construction frame. Therefore the transmission device is able to be supported by the rear axle in the transmission cavity to transmit a rotation output from the engine to drive the rear axle to rotate for driving the rear wheels to rotate.
