Title: Liquid crystal display device
Inventor: ASANO KAZUO
IPC: G02F1/133
Filed: 1988-09-10
Abstract: PURPOSE:To decrease leak light and to obtain high contrast by providing a liquid crystal cell having a liquid crystal layer disposed in such a manner that the nematic liquid crystal added with an optically active substance forms a twisted structure between a pair of electrode substrates having oriented layers and providing a pair of polarizing plates disposed on both sides of the liquid crystal cell. CONSTITUTION:The twist angle alpha of the twisted structure of the liquid crystal layer 20 is 220 to 300 deg.. This twist angle alpha can be regulated by the orientation treatment direction of the oriented layers formed respectively to a pair of the substrates 11, 12 and the kinds, amts., etc. of the nematic liquid crystal and the optically active substance to be added thereto. The product DELTAn.d of the magnitude DELTAn of the refractive index anisotropy of the nematic liquid crystal and the thickness d(mum) of the liquid crystal layer 20 is required to be 0.60 to 1.1mum. The angles (deviation angles) beta and gamma between the polarizing plates 41 and 42 and the orientation direction of the liquid crystal molecules in contact with the surfaces of the substrates 11 and 12 adjacent to the respective polarizing plates satisfy equations I and II. The leak light is decreased in this way and the higher contrast than heretofore is obtd.

Filed: 1988-09-09
Abstract: PURPOSE:To enable even a projection optical system sensitive to any changes in temperature to maintain the image formation characteristics by a method wherein an image formation characteristics correcting means to correct the fluctuations in said characteristics caused by the passage of illuminating light as well as a thermostatic means for the projection optical system only are simultaneously actuated to be complemented with each other. CONSTITUTION:The fluctuations in the environmental conditions are measured by a measuring instrument 14 to transmit the signals of the fluctuations to a controller 10. The environmental conditions, magnification and the changes in the focal positions are previously measured by experiments to be stored in the controller 10 in the forms of formulas or tables, etc., for computing the changeable amounts. Next, the changes in the image formation characteristics by the absorption of illuminating light are computed by shifting an illumination intensity sensor 11 to the position below a projection lens system 7 so that the lens system 7 may measure the passing energy to transmit the signals of the measurements to another controller 11. Through these procedures, the image formation characteristics can be easily corrected with high precision by especially thermostatting the title projection optical system only furthermore the system can be simplified because the change in the image formation characteristics by the absorption of illuminating light can be coped with simply by averting the effect of the change in outer temperatures measured by integrating the illuminating energy.

CONSTITUTION:The dial 1 is constituted of the dial plate 2 consisting of a copper material and an auxiliary member 3 of an ornamental element consisting of characteristics and symbols. Pale color and transparent plastic paint is applied on the surface. An auxiliary member 3 has two pieces of foot parts 3A having about 3mm diameter for the purpose of mounting, is inserted into the guide holes 2A provided on the body 2 and is fixed by caulking and adhesive agent. Since the paint 5 is applied as well in the hole 2A having no need for painting at the time of painting of the body 2, the holes 2A are irradiated with the laser beam to burn the paint 5A in the hole part in order to remove the paint. Since the material of the body 2 is the copper system, the holes 2A are not deformed by the output of the laser beam and the initial size of the processing is assured. The positioning of the laser beam and the holes 2A is automated by automatically calling out the coordinate data of the holes 2A from a CAD and combining the data with a multiaxis NC control unit using a three-dimensional table.
