Filed: 1981-12-10
Abstract: PURPOSE:To output an accurate tracking control signal invariably by discriminating difference signals of symmetrical element couples of 4-split photodetecting element and changing over a switch generate a tracking control signal. CONSTITUTION:Detection outputs of symmetrical element couples of 4-split photodetecting element (a) and (c), and (b) and (d) of a photodetector 10 are supplied to subtracters U1 and U2 for subtraction; when the output of the subtracter U1 is positive or zero, the discriminator U5 of a control circuit 21 is put in operation and only when the output of the subtracter U2 is negative, a switch 20 is connected to a contact (g). By the inversion output by a subtracter U4 and the output by the subtracter U1, a tracking control signal is generated and when the output of the subtracter U2 is positive, the tracking control signal is generated by its output and the output of the subtracter U1. Even when the output of the subtracter U1 is negative, an accurate tracking control signal is outputted similarly.

Filed: 1987-08-12
Abstract: PURPOSE:To obtain the titled compound having extremely low intravenous toxicity and useful as an intermediate for X-ray contrast medium, by recovering the residue of acetic anhydride used in the reaction and acetic acid used as a solvent by distillation and repeatedly using the recovered materials in diacetylation reaction. CONSTITUTION:In the production of 3,5-diacetylamino-2,4,6-triiodobenzoic acid, residual acetic anhydride used in the reaction and acetic acid used as a solvent are recovered by distillation and used in the diacetylation reaction of 3,5- diamino-2,4,6-triiodobenzoic acid. The raw material cost can be remarkably reduced by this process. the distillation may be carried out under normal pressure or reduced pressure preferably in anhydrous state because acetic anhydride reacts with water to form acetic acid. Since the reaction system contains sulfuric acid, the distillation temperature is lower the better.
