Title: Liquid crystal display device and its production
Inventor: SUZUKI HISATAKA
IPC: G02F1/1337
Filed: 1993-07-23
Abstract: PURPOSE:To provide a liquid crystal display device which is improved in visual angle characteristics not only in forward and backward visual angle directions but also in a direction perpendicular thereto and has a high display grade in the region of the equal visual angle characteristics extending over a wide range. CONSTITUTION:Regions where different orientation characteristics face each other and regions where the equal orientation characteristics face each other are made to coexist between both substrates 1 and 11. The visual angle characteristics in the direction perpendicular to the two directions, forward and backward, are formed by a combination of the equal pretilt angle delta between both substrates 1 and 11. Since the visual angle characteristics in the direction perpendicular to the two directions, forward and backward, are formed by the combination of the equal pretilt angle delta, the visual angle characteristics from two to three directions are uniformalized. The boundary 6 of the different orientation states of the one substrate is arranged so as to divide the one orientation state of another substrate and, therefore, there is no need for forming a black matrix at the boundary 6 by allowing for a deviation.

Abstract: PURPOSE:To prevent deformation and damage of an underground pipe, improving thereby execution efficiencies, by holding and fixing an underground pipe to a driving axial body provided therein by means of an expansion mechanism and imparting thrust to the underground pipe together with the driving axial body as an excavation means advances so that the thrust is dispersed. CONSTITUTION:An expansion bag body 40 of a driving axial body 2 is deflated so that said body 2 is inserted into an underground pipe 3 and connected to the rear part of an excavation means 1 which excavates horizontally from a vertical hole V.
