Abstract: A color liquid crystal display device in which a color filter is provided over the entire surface of the glass substrate. In a first embodiment, display electrodes extend over a plurality of color filter sectors to form segment electrodes. In a second embodiment, the transmissivity of light passing through the liquid crystal layer can be varied in levels by making the display electrodes in two-layer, operating voltage on each of the electrodes independently, and varying in levels the amplitude of voltage applied on the liquid crystal layer by the display electrodes. In a third embodiment, the amount of light transmitted in the display area of a color filter sector is controlled by two or more display electrodes which divide up the display area.

Abstract: Inclusion of alginate in enzyme-conjugate incubation solutions is used to improve performance of immunoassays. The total binding of antibody-signal producing species conjugate is enhanced and the specific binding is enhanced more than the non-specific binding. This allows a lower detection limit to be achieved in these assays.

Escape of the fluid is inhibited by a barrier layer of an oriented lyotropic liquid crystal polymer film. Preferred polymers include polybenzazole (PBZ) polymers.

Abstract: A method for immunochemical determination of a hapten in a sample is disclosed, in which(A) a high-molecular compound to which the hapten is bound (reagent A),(B) insoluble carrier particles carrying thereon an antibody to the hapten (reagent B), and(C) magnetic substance-containing insoluble carrier particles carrying thereon an antibody to an antigenic determinant in the high-molecular compound and different from the hapten (reagent C),are used. These three reagents are dispersed in the sample, then, a magnetic field is applied to separate from the reaction mixture unreacted reagent (C) and agglutinated particles formed from the reagent (B) and the reagent (C) through the reagent (A). The amount of the reagent (B) remaining dispersed in the reaction mixture is measured, thereby determining the extent of competitive inhibition to the agglutination of the reagent (B) and the reagent (C) through the reagent (A) by the reaction between the hapten in the sample and the reagent (B).

Abstract: An improved ferroelectric liquid crystal device comprising a pair of substrates each provided with voltage applying means, at least one of the substrates having an orientation control layer, and a ferroelectric liquid crystal layer disposed between the pair of substrates, the ferroelectric liquid crystal layer comprising specific .gamma.-lactone derivatives, which is useful as a liquid crystal shutter, liquid crystal display device or the like.

Abstract: The present invention is based upon the discovery that ordered polymers, such as PBzT, can be readily formed into tubular structures which retain a biaxial orientation imparted thereto during processing, and that these rigid, high-stiffness tubular components can exhibit near zero coefficient of thermal expansion (CTE). Zero CTE materials are not adversely affected by vast swings in temperature, e.g., from very hot to very cold in short periods of time, nor are they adversely affected by long term exposure to either temperature extreme. The tubular components of the present invention thus represent a revolutionary advance in space based hardware, as the extreme temperatures experienced there will not affect rigidity of structures built using these components.

Abstract: A developer unit which includes a developer tank housing a developing roller including a sleeve and a magnet member both rotatable, wherein the magnet member is rotated longer than the sleeve, and wherein the rotating direction of the magnet member is opposite to that occurring when the sleeve and the magnet member rotate simultaneously. This strengthens the stirring force for the developer, thereby enhancing the chargeability of the toner and maintaining a desired image density.

Abstract: The present invention provides human B lymphoblastoid cell line AC-33, which is novel, and excellent in proliferativity and fusion capability, and works well as the parental line for obtaining a human monoclonal antibody-producing hybridoma. Said hybridoma possesses excellent proliferativity and stable antibody productivity, thus permitting efficient antibody production over a long period.
