Abstract: A corrected data generator for an image taking device includes a training plate having a reference pattern. A memory stores predetermined image information corresponding to the reference pattern on the training plate. A photoelectric section converts a light signal into a corresponding electric signal. Corrective information is generated in response to an electric signal of the reference pattern which is outputted from the photoelectric section, and in response to the image information stored in the memory. An electric signal of an object which is outputted from the photoelectric section is corrected in response to the corrective information.

Abstract: A modified strongly acidic ion exchange resin of a sulfonic acid type is disclosed. Modification is conducted by ionically binding a particular N,N-di-substituted mercaptoalkylamine to a strongly acidic ion exchange resin of a sulfonic acid type. The N,N-di-substituted mercaptoalkylamine is specifically represented by the following formulae: ##STR1## wherein R.sup.1 represents hydrogen or a C.sub.1-6 alkyl group, R.sup.2 and R.sup.3 independently represent a C.sub.1-10 alkyl group, a and b denote 0-3, respectively, a+b denotes 2 or 3, and m denotes 4 or 5. The modified ion exchange resin makes an improved catalyst in the preparation of a bisphenol by the condensation reaction of a phenol with a ketone.

Abstract: A process for producing 2,6-naphthalenedicarboxylic acid by oxidizing 2,6-dimethylnaphthalene by molecular oxygen in the presence of a catalyst including cobalt, manganese and bromine. The oxidation reaction is performed by using a 2,6-dialkylnaphthalene mixture of 2,6-dimethynaphthalene and a small amount of 2,6-diisopropylnaphthalene as a raw material. Thus, the desired 2,6-naphthalenedicarboxylic acid can be produced at a high yield.
