    摘要： A liquid crystal device is constituted by a pair of transparent substrates each having thereon a transparent electrode, and a chiral smectic liquid crystal composition lacking cholesteric phase disposed between the substrates so as to assume at least two optically stable states. At least one of the substrates is provided with an alignment film which comprises a polyimide represented by a recurring unit of formula (I) shown below and has been subjected to a uniaxial aligning treatment.
    wherein A denotes a tetravalent aliphatic hydrocarbon group free from a planar structure or a tetravalent alicyclic hydrocarbon group, and n is an integer of at least 1. The chiral smectic liquid crystal composition may preferably contain at least one species of fluorine-containing mesomorphic compound comprising a fluorocarbon terminal portion and a hydrocarbon terminal portion connected with a central core and having a smectic phase or a latent smectic phase.

    摘要： An image forming apparatus has a book binding mechanism for performing a book bind operation using front sheets of a plurality of sizes which can bind a bundle of sheet members recorded by said image forming apparatus, and have limitations on the numbers of recorded sheet members to be bound. The image forming apparatus further has output means for outputting sheet number data according to a bundle of sheet members; judge means for judging whether or not the sheet number data output from said output means is larger than a range of the limitation; detect means for, when the judged result from said judge means is affirmative, dividing the sheet number data, and detecting a divided sheet number value which falls within the range of the limitation; and control means for controlling to perform a book bind operation in units of the sheet numbers detected by said detect means.

    摘要： An optically active mesomorphic compound is represented by the following formula (I):
    wherein R₁ and R₂ are respectively an alkyl group having 1 to 16 carbon atoms, and C* denotes an asymmetric carbon atom. The mesomorphic compound has a fluorine atom directly connected to the asymmetric carbon atom and is effectively used as a liquid crystal component providing an increased spontaneous polarization and an improved responsive­ness.
