Abstract: Provided is a heat storage device which can stably store heat by storing heat within a fixed temperature range. A heat storage device (10) of the present invention is characterized in being provided with a heat resistant frame (11), which is filled with one kind of alloy or mixed salt having a predetermined eutectic temperature, alternatively, a heat resistant frame (11), which is filled with two or more kinds of alloys or mixed salts having different eutectic temperatures, by having the alloys or the mixed salts adjacent to each other in the order of eutectic temperature levels with a partitioning wall (11a) therebetween.

Abstract: A method that manufacturers an optically active carboxylic acid ester at high yield and high enantioselectivity is provided. An optically active carboxylic acid ester is manufactured at high yield and high enantioselectivity by reacting a racemic carboxylic acid and a specific alcohol or phenol derivatives in a polar solvent having a dipole moment of 3.0 or higher in the presence of an acid anhydride and an asymmetric catalyst, esterifying one enantiomer of the racemic carboxylic acid at high selectivity, and increasing the amount of esterified carboxylic acid by racemizing the optically active carboxylic acid which is the other enantiomer not used in esterification.

Abstract: A simple and practical image restoring device capable of improving the performance of image restoration. An image restoring device (100) is provided with a first restoration processing unit (160a) and estimates original image information from the degraded image information into which information unnecessary for the original image information is incorporated. A correlation calculating section (164) calculates the correlation value of the estimation error of when the state amount of a system at time n+1 including the original image information is estimated by information up to time n or the time n+1 with respect to the degraded image information of only the time n.
