Filed: 1988-06-17
Abstract: PURPOSE: To form a read line having a narrow width and to reduce power consumption by irradiating the beam of a laser diode on a voice track while converging the beam with an optical system consisting of a convergent concave mirror having a prescribed inclined angle or the like. CONSTITUTION: An incident beam 9 is forked by reflecting the 1st-order beam 3 from a laser diode 4 by a plane mirror 12. The incident beam 9 is reflected by a convergent concave mirror 12 to become a read beam 40, which passes a circular opening for irradiation 15 to be irradiated on the voice track of a film 16 and is converted into an electric signal by a photocell 34. At this time, the mean inclined angle of the concave mirror 12 is properly adjusted within the range of 5 deg.-85 deg.. Thus, the width of the read line is made to be a prescribed narrow width and also since the beam having a low divergence is used. the energy loss is prevented and power consumption is reduced by using such an optical system.

IPC: G02F1/13
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent overfilling of liquid crystal and provide a method of manufacturing liquid crystal cell permitting compatibility of filling-time shortening and display failure reduction by adjusting an area of an opening part in contact with liquid crystal material smaller than an actual opening part area, and filling the liquid crystal material while pressurizing it.

The liquid crystal material is injected by pressure from the liquid crystal inlet 5 by using such a liquid crystal injection system while de-gassing the inside of the liquid crystal cell 1 from a discharge port. Thus, although a liquid crystal injection time is aimed at shortening, this method permits to perform accurate adjustment of the injection pressure, prevent overfilling of the liquid crystal material, and prevent gap material from moving, and prevent a flow mark from occurring.  Therefore, it is possible to provide a liquid crystal display device of excellent display quality at a low cost.
