Filed: 1986-01-31
Abstract: PURPOSE:To enable the securing of a broad dynamic range with a single unit, by changing a voltage to be applied to a photoelectric multiplier tube according to a light detection output. CONSTITUTION:A light detection current Ip output from a photoelectric multiplier tube 1 according to the quantity of light l to be detected, converted into a voltage E0 with a current-voltage converter 3 of a detection circuit 2 and a high voltage is applied via a switch SW from a power source 5. Consequently, the voltage 5 supplies the voltage E0 by reducing the absolute value of a small driving voltage (-VH) all for the larger voltage E0. Therefore, the sensitivity of the multiplier tube 1 is automatically heightened for less quantity of light and it automatically lowered for a larger quantity of light, thereby compressing variation of the detection voltage E0. This can secure a broad dynamic range with a single photodetector.

IPC: G02F1/1337
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To form an alignment layer for a liquid crystal having good alignment of molecules without rubbing treatment by allowing a polymer soln. having strong polar groups on the molecular ends to flow on a substrate while applying a DC electric field perpendicular to the substrate and then baking the soln. on the substrate. SOLUTION: A soln. 5 of an oligomer or polymer having strong polar groups such as trifluoromethyl groups introduced to at least one of the molecular ends is made to flow on a substrate 2 while a DC electric field perpendicular to the substrate 2 is applied. By this method, the molecular and with substitution of strong polar groups is adsorbed to the surface of the substrate 2 and the solvent is vaporized by heating or the soln. is cured by heating while molecules of the alignment layer are aligned in one direction by the flowing force of the soln. 5. The trifluoromethyl groups on the molecular end of the polymer which flows on the interface between the substrate 2 and the polymer soln. 5 adsorb the surface of the substrate 2 by Coulomb force.  The solvent molecules collide in the direction of the flow with the polymer molecules which adsorb at the molecular end to the surface of the substrate 2, which render the molecular chains of the polymer oriented in the flowing direction. By carrying out this process for a given time, a film of certain thickness containing aligned polymer molecular chains can be formed on the interface of the substrate 2.
