Abstract: PURPOSE:To improve the reliability of sticking and the selectivity of polarizing plates by sticking a sheet with a self-adhesive part connected with a spring to one end of a surface protective film and moving a base plate, thereby sticking the polarizing plate onto a substrate. CONSTITUTION:The polarizing plate 1 and the substrate 2 for a liquid crystal display element are so positioned as to be integrally superposed while a separator 14 of the polarizing plate 14'' is not stripped. One end of the surface protective film 7 of the polarizing plate 1 is then adhered to the sheet 4 with the self-adhesive part. The separator 14 of the polarizing plate 1 is thereafter stripped over the entire surface to expose a self-adhesive layer 13 and the front end of the polarizing plate 1 is lifted by the elastic force of a spring 5. The front ends of the polarizing plate 1 and the substrate 2 are registered and the starting part for sticking is lightly pressed by a roller 3, then the base plate 6 is moved in the direction of an arrow. Pressure is thereby exerted between the base plate 6 and the roller 3 by which the polarizing plate and the substrate are continuously stuck together and the surface protective film of the polarizing plate is stripped. The sticking of the polarizing plate and the substrate without allowing air bubbles to enter the same is thereby permitted and the flawing of the surface of the polarizing plate is obviated.

Abstract: PURPOSE:To enable the regeneration of an element having a pinhole generated therein, by applying high voltage to both electrodes and allowing a large current to flow to a short-circuit area at the area where the pinhole is generated in the element. CONSTITUTION:A pyroelectric element 1 having a pinhole 1a, electrodes 2, 3, a power source 4, a condenser 5 and a switch 6 are provided. When the switch 6 opened at first is closed, because the pyroelectric element 1 itself permits the passage of no current, the charges of a condenser 5 flow to the pinhole 1a, where both electrodes 2, 3 short-circuit, all together in a concentrated state. Therefore, the short-circuit area generates heat and the electrodes at the short-circuit area are scattered and the electrode part short-circuited at the pinhole 1a is lost and both electrodes, 2, 3 are brought to an insulating state. By this method, the element having the pinhole generated therein can be regenerated.
