Title: Liquid crystal display device
Inventor: TOUJIYOU TOSHIHIKO
IPC: G09F9/35
Filed: 1983-01-31
Abstract: PURPOSE:To improve display quality by disposing a neutral polarizer on the outside surface of a liquid crystal display element with the absorption axis made parallel therewith, and disposing a polarizer having the absorption axis intersecting orthogonally with said absorption axis, a display pattern and a light source on the one outside surface thereof. CONSTITUTION:The light radiated from a light source 11 is polarized by a multicolor polarizer 10 and is made incident to a neutral grey polarizer 9. Since the absorption axis of the polarizer 10 intersects orthogonally with the absorption axis a2 of the polarizer 9, only the light of the wavelength region showing a specific color is made incident to a liquid crystal display element 1 and the other light cannot be transmitted through the polarizer 10. The same holds true of the case in which the driving voltage is not impressed between electrodes 3a and 3b. If the driving voltage is impressed between the upper and lower electrodes 3a and 3b in contrast with the above-mentioned case, the optical rotatory power of a liquid crystal 4 is lost between 3a and 3b and the light transmitted through the liquid crystal 4 is transmitted through the polarizer 6a as it is and only the character A of the color polarizer 10 of a negative-printed two- layered polarizing plate 8 is displayed in a red color on the black ground by an electrode pattern. As a result, the display pattern having high contrast is obtd.

Title: Method and apparatus for manufacturing cement clinker
Inventor: JIERAARU NAMI
IPC: F27B1/00
Filed: 1981-01-30
Abstract: A process and apparatus for manufacturing cement clinker in which pellets of raw material containing the necessary components for manufacturing the clinker are introduced into an apparatus where the pellets flow under gravity, successively through a preheating zone, a clinkering zone using a fluidized bed and a cooling zone. The pellets contain an amount of comminuted carbon determined so that its combustion produces an amount of heat within each pellet sufficient to carry out decarbonation of the material, taking into account the heat introduced by the hot gases passing upwardly through the apparatus. Decarbonation is completed at the base of the preheating zone and the pellets enter the clinkering zone at a temperature which is close to the clinkering temperature. Additional heat is supplied through burners within the clinkering zone.

Title: Production of phase shift mask
Inventor: SATO JUNICHI
IPC: G03F1/30
Filed: 1993-01-28
Abstract: PURPOSE:To form a groove-type phase shifter by dry etching a glass substrate while maintaining high selectivity for a Cr light-shielding film. CONSTITUTION:When a groove 1a as a phase shifter is formed on a glass substrate 1, it is difficult to completely align the edges of a resist mask 4 and a Cr light-shielding film 2 and the edge part of the Cr light-shielding film 2 is apt to be exposed. To prevent corrosion of the exposed area by F*, the exposed area is treated to make a surface protective area 5 by using an etching gas which releases isolated S in plasma under discharge dissociation conditions. A wall protective film 4 is formed by deposition of S on the side wall of the pattern, however, this film does not prevent etching in the exposed area of the glass substrate 1 because the deposited S is burnt and removed by O atom released from the exposed area. As for the etching gas, a sulfur compd. such as S2F2 and CSF2 is used.
