Abstract: The present invention provides a dimming panel sequentially including: a first substrate; a liquid crystal layer; and a second substrate, the first substrate sequentially including an insulating substrate, a first electrode, a first insulator layer, and a second electrode, the second electrode including, in a plan view, linear electrodes parallel to each other with slit regions in between, and bridge electrodes each of which is disposed in one of the slit regions and is connecting two adjacent linear electrodes, the bridge electrodes including a first bridge electrode in a first slit region, a second bridge electrode in a second slit region adjacent to the first slit region, and a third bridge electrode in a third slit region adjacent to the second slit region, the first bridge electrode, the second bridge electrode, and the third bridge electrode being discrete from one another.

Abstract: A strip cooling apparatus for a continuous annealing furnace for continuously treating longitudinally fed steel strip has a pair of cooling gas chambers attached to the furnace walls on both sides of the strip so that the front of each chamber faces the strip. Each cooling gas chamber has nozzles having round outlets opening toward the strip surface on its front side to shoot forth a cooling gas jet against the strip furnace. The nozzle is separated from the strip by a distance z not larger than 70 mm and projected from the front of the cooling gas chamber by a length of not less than (100--z) z) mm. The cooling apparatus also has a pair of rotatably holding rolls reciprocatably attached to the furnace walls to press the strip at a right angle thereto. The holding rolls holds the strip and prevents the occurrence of fluttering.
