Title: Liquid crystal display device
Inventor: YOSHIDA HIDESHI
IPC: G02F1/1335
Filed: 1989-08-04
Abstract: PURPOSE:To improve contrast by confining the product of the refractive index anisotropy DELTAn and thickness d of a twisted liquid crystal layer of <=0.7mum, thereby decreasing the fluctuation in the dispersion angle of the light passing a driving panel to <=45 deg. to obtain the common optical axes of the respective wavelength components in a stretched film. CONSTITUTION:The super twisted nematic liquid crystal is used as the twisted liquid crystal and the double refraction DELTAn.d of the liquid crystal layer 4 are specified to about 0.6mum. The stretched film 5 is for correcting the dispersion of light and the stretching direction of the stretched film 5 is approximately aligned to about the center of the dispersion angle. The respective R, G and B components in the stretched film 5 are polarized with the stretching direction of the stretched film 5 as the common optical axis so that the polarization direction of the respective R, G and B components at the time of emission from the stretched film 5 are nearly in alignment to the stretching direction and the dispersion of light is nearly absorbed. The fluctuation in the dispersion angle of the light past the driving panel is confined to <=45 deg. in this way and the liquid crystal axes of the respective wavelength components in the stretched film are made common. The contrast is thus improved.

Title: Method of establishing signal passage between at least two apparatuses and arrangement of apparatuses
Inventor: BERUNARUDO FUAN SUTEENBURUUFUE
IPC: H04B1/20
Filed: 1987-08-17
Abstract: In a system comprising a collection of signal processing apparatuses (1, 2, 3, 4) and a switching device (5), each apparatus is connected, by means of a universal connector (6, 7, 8, 9) which is identical for each apparatus, to an arbitrary connection of the said switching device. The signal path between two or more connected apparatuses is established in that a first apparatus supplies a report command for the switching device in at least one further apparatus, after which the switching device finds out to which connector a further apparatus is connected in that said further apparatus in reaction to the report command has supplies an identification signal as a result of which the switching signal recognises the connector to which said further apparatus is connected. Once it has been found out to which connector the first and the further apparatuses have been connected, the switching signal establishes a signal path herebetween.

Abstract: PURPOSE:To reduce a noise component in a digital signal and to calculate ghost information accurately by providing a noise eliminating circuit between a video signal A/D converting circuit and a ghost arithmetic circuit. CONSTITUTION:A signal passed through a transversal filter (TR)1 is subtracted from an input video signal to obtain a ghost-free output video signal. The leading edge of a vertical synchronizing signal is extracted 3 from the output composite video signal and its difference 4 from a slightly-delayed signal is calculated. This difference signal is converted by the A/D converting circuit 5 into a digital signal and is supplied to a noise eliminating circuit 8 to remove random noise by digital processing and to apply the resulting signal to the ghost arithmetic circuit 6. The amplitude of a ghost and a delay time are calculated on the basis of the noise-removed digital signal to change the tap gains at every stage of the TF1.

Title: Manufacture of thermosettable coloring agent
Inventor: FUOOCHIYUNATO JIEI MIKARU
IPC: C08J3/20
Filed: 1988-08-17
Abstract: Processes characterized by dissolving a dye in a solution of organic solvent and an epoxy resin type polymer, which requires a curing agent in order to create a resultant nanosphere that will crosslink through the action of the curing agent, and not simply as the result of a solvent removal which defined each nanosphere. The dye may be in a concentration range of 1% to 50% by weight of solvent, and the organic solvent must have limited solubility in water, typically less than 20%. An initial intermolecular mixing step dissolves dye and epoxy resin within a solvent so as to make a homogeneous solvent/polymer/dye intermediate mixture, that then is dispersed as nanoparticles in water, and thereafter crosslinked. Surfactants may be used to assist in dispersing the dye/polymer/solvent solution into the water continuous phase.
