Title: Liquid crystal display device
Inventor: KUBOTA KANEMITSU
IPC: G02F1/133
Filed: 1985-07-05
Abstract: PURPOSE:To uniform contrast and density over the entire surface of a liquid crystal display surface by putting a Fresnel lens between a liquid crystal display panel and an observer and varying the saw-tooth angle of the Fresnel lens locally. CONSTITUTION:Emitted light 13 from a back light is transmitted through the liquid crystal display panel 12 and then refracted by the Fresnel lens 11 to enter the eye of the observer 14. When an angle 15 is theta5, 16 theta4, 17 theta3, 18theta2, and 19 theta1 (angle to a line perpendicular to the panel), equations (1)-(4) hold, where psi is the saw-tooth angle as shown in a figure. When the Fresnel lens 27 is so designed that only light incident at a constant angle 20 of incidence enters the eye 23 of the observer over the entire surface of the display surface, the saw-tooth angle psi at a point 2 is only set to about 37.8 deg. so that theta5(20)=30 deg. and theta1(22)=10 deg..

Abstract: PROBLEM TO BE SOLVED: To prevent gas leakage from a heat treating furnace by providing a gas pipe with an exhaust gas pipeline for introducing decomposition gas downward from the gas pipe into a gas combustion furnace thereby preventing tar from adhering to the pipe to cause pressure rise. SOLUTION: A gas combustion furnace 34 introduces decomposition gas (exhaust gas) generated in a desalting furnace 1 and a volume reducing furnace 20 from pipes 35, 36 trough an exhaust gas pipeline 50. After tar is combusted, the decomposition gas is cooled, passed through a bug filter for removing dust and discharged.

The standing pipe 53 is coupled with the gas combustion furnace 34 and exhaust gas from the gas pipes 35, 36 is introduced from the inclining pipes 51, 52 into the gas combustion furnace 34 trough the standing pipe 53. The inclining pipes 51, 52 incline downward from the joint of the gas pipes 35, 36 and tar stands at the lower part of the standing pipe 53 upon liquefaction. Inclination angle is determined while taking account of the temperature, viscosity of tar, and the like, at the installation place.
