Title: Liquid crystal cell and liquid crystal display device
Inventor: OKAMURA MORIYUKI
IPC: G02F1/1341
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent the washing away of liquid crystals near to an injection port at the time of liquid crystal injection, to enable the cleaning and expulsion near the injection port by washing-away and the easy attachment, detachment, etc., of a liquid crystal injection machine and to make a yield higher, a cost lower and productivity higher by subjecting the part near the injection port exclusive of the liquid crystal injection port to a liquid repulsion treatment in such a manner that the supplied liquid crystals are held right above the injection port and are not washed away to the outside of the injection area. SOLUTION: The liquid crystals 6 supplied from a liquid crystal supplying means are held in a high contact angle state by the liquid repulsion effect of a liquid repulsion treating agent 5 coated with a fluorinated hydrocarbon resin right above the liquid crystal injection port 4. The liquid crystal injection port 4 is then end-sealed to a hemispherical shape, by which the injection stage may be surely completed without the washing-away of the liquid crystals to the outside of the injection region enclosed by the liquid repulsion treating agent 5. The part near the injection port 4 is thus coated with the fluorinated hydrocarbon resin which is the liquid repulsion means with which this part is treated, by which the good injection may be achieved with an extremely little amount of the liquid crystals to be used.  As a result, the deficiency of the injection by the washing-away of the liquid crystals is eliminated and defects are decreased.

IPC: G02B6/36
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a connector which can remove undesirable non-signal light and can, therefore, improve the safety of the eye. SOLUTION: The connector has a fiber stub 8 which makes it possible to pass light between a semiconductor device such as a semiconductor laser and a waveguide such as an optical fiber.

Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To produce the subject polyurethane resin without eluting a metal catalyst to the outside of the system by using an isocyanate group-terminated prepolymer or a polyol having an alkoxytitanate structure in the molecule. SOLUTION: (A) A polyol having an alkoxytitanate structure in the molecule is reacted with a polyisocyanate in excess of isocyanate groups to thereby provide an isocyanate group-terminated prepolymer having the alkoxytitanate structure in the molecule. For example, (B) a tetraalkyl titanate (e.g. tetrapropyl titanate) is reacted with a polyol without containing a titanate (e.g. polyethylene glycol) to afford a polyol having the alkoxytitanate structure in the molecule. The objective resin is produced by, e.g. a method for using both the components A and B and reacting the component A with a short-chain polyol. Since the resultant resin has the titanate group having catalyst effects in the polymer, elution preventing effects on the catalyst are achieved.
