20100097572 | Deforming method for deformable mirror, aberration compensation method for optical apparatus, aberration compensation method of ocular fundus observation apparatus, aberration compensation apparatus, optical apparatus and ocular fundus observation apparatus - A deforming method for a deformable mirror having plural electrodes and a reflective membrane which are distorted by static voltages. The Zernike voltage template used to deform a deformable mirror is adapted for aberration correction by calibrating each component template according to the specificity of the mirror. The voltages applied to the electrodes to form a surface profile of the reflective membrane are measured based on the reflection light from the membrane. A certain number of voltage-by-electrode patterns each of which corresponds to a different reference profile of the reflective membrane and specifies each set of a voltage and an electrode to which the voltage is to be applied are stored preliminarily. The reflective membrane is deformed to a desired profile by superposing preliminarily stored voltage-by-electrode patterns. The deformation of the mirror is corrected by calibrating each template according to the operational environment. | 04-22-2010 |

In an ink composition for printing on foamed paper containers, which contains a colorant, a binder resin and a solvent, a resin having an elongation ratio (elongation ratio as measured with a small-size tensile tester manufactured by Intesco Co., Ltd., under the conditions of a tensile speed of 100 mm/min and room temperature (25° C.)) of 400% to 3,000% is used as the binder resin. The binder resin is preferably a mixture of a urethane resin:vinyl chloride/vinyl acetate copolymer (=50:50 to 99:1), and the urethane resin is more preferably a polyurethane-urea resin. A non-aromatic solvent is used as the solvent. | 05-05-2011 |
