Title: Liquid crystal alignment film, its production, liquid crystal display device using the same, and its production
Inventor: OTAKE TADASHI
IPC: G02F1/1337
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To obtain a new liquid crystal alignment film to extremely increase the viewing angle and a method for the production of this film, and to obtain a liquid crystal display device having the aforementioned liquid crystal alignment film, and a method for the production of the device. SOLUTION: The pretilt angle is uniformly varied in the radial direction from the center part to the peripheral part in each pixel, and the liquid crystal molecules are aligned along the pretilt angle. Thereby, the refractive index anisotropy of the liquid crystal molecules is averaged in all directions to the incident rays in each pixel unit when the display is observed in any direction to the normal line of a display screen. Thereby, variation in the transmittance depending on the visible direction is decreased, which increases the viewing angle to improve the viewing angle characteristics.

Inventor: KODAMA YUTAKA
IPC: B41J2/175
Filed: 1978-06-06
Abstract: PURPOSE:To eliminate air bubbles and clogging readily without removing the head by preventing the ink drops being injected from arriving at recording paper with a gutter and circulating the ink through changing over of valves thereby removing the air bubbles of the ink in the head and eliminating the clogging of the head. CONSTITUTION:When printing failure owing to production of air bubbles, etc. occurs, a gutter 8 is elevated by a solenoid or the like. Solenoid valves 6, 7 are then opened and closed and a pump 5 is energized. As a result, the ink circulates through the filter 3, head 1, gutter 8 for blocking the arrival of ink drops at recording paper 2 and ink tank 4. The air bubbles are exhausted through the vent hole of the tank 4, whereby the air bubbles in the head 1 are removed. When the valves 6, 7 are closed and opened, the nozzle clogging of the head 1 is removed by the ink which is boosted by the pump 5, thus the removal of the air bubbles and clogging may be readily and surely accomplished without removing the head.
