Title: Production of 3,5-diamino-2,4,6-triiodobenzoic acid
Inventor: UTSUNOMIYA ATSUSHI
IPC: C07C229/60
Filed: 1987-12-18
Abstract: PURPOSE:To efficiently obtain the title compound useful as an intermediate for roentgenographic contrast media with extremely low intravenous toxicity, by concentrating and recovering hydrochloric acid from a reaction system and repeatedly using the resultant hydrochloric acid for reaction. CONSTITUTION:3,5-Diamino-2,4,6-triiodobenozoic acid is obtained. In the process, hydrochloric acid from a reaction system is concentrated, recovered and repeatedly used for reaction. Iodine monochloride as an iodinating agent is reacted with 3,5-diaminobenzoic acid in an aqueous solution of hydrochloric acid to provide the aimed compound. In the reaction, the resultant filtrate after filtering off crystals of the aimed compound is treated with active carbon to remove a very small amount of iodine and organic substances. After concentration at a temperature within the range of 100-109 deg.C, the hydrochloric acid in a high concentration is recovered and repeatedly used as a solvent for the next reaction to simplify waste liquor treatment.

This substrate and the selected dense phase gas (e.g. CO2 ) are brought into contact with each other under the pressurization above the critical pressure of the gas. Next, the temp. of the gas is changing by a series of steps between the temp. higher than the critical temp. of the gas and the temp. lower than this critical temp. to change the phase of the gas between the liquid state and a supercritical state. The temp. at the completion of the respective steps is maintained for a prescribed time and the contact of the gas with the substrate contg. the contaminants is maintained for a prescribed time in the respective steps. The solvent vector of the gas are applied at this time, by which the >=2 contaminants are removed from the substrate.

IPC: G01G23/01
Filed: 1989-12-11
Abstract: PURPOSE: To determine the operation of a weighing apparatus accurately and automatically by checking the operation using a signal related to a varied parameter from a capacitance detection circuit. CONSTITUTION: The weighing apparatus comprises a variable capacitance load cell 20, and a capacitance detection circuit 22 generating an analog signal indicative of the weight of the load cell 20. An analog weight signal from the circuit 20 is converted through an A/D converter 25 into a digital value which is transmitted to a microcomputer 28. The computer 28 compares the weight signal received from the converter 25 with a determination value stored in a memory 30 and presents the comparison results on a display 31. The determination value is the difference between the reading of weight when no load is applied to the weighing apparatus and a reading obtained after a determination circuit 35 is instructed by the computer 28 to vary the value of the parameter in the circuit 22.

Title: Semiconductor optical waveguide
Inventor: WAKAO KIYOHIDE
IPC: G02B6/122
Filed: 1987-12-16
Abstract: PURPOSE:To smooth a reflection mirror surface and to reduce the reflection loss on the reflection mirror surface by forming layers with a low and a high refractive index by using the same semiconductor materials which differ in added impurity concentration. CONSTITUTION:A semiconductor layer which is provided with an optical waveguide and has the high refractive index and semiconductor layers on both sides which have the low refractive index are formed of the same semiconductor materials, and they are made different in impurity concentration to form the high-refractive-index layer with small impurity concentration and low-refractive- index layers which have large impurity concentration. For example, an n<-> InP layer 12 is larger in refractive index than n<+> InP layers 13 and 14, so light is confined to the n<-> InP layer 12, wherein the optical waveguide 11 is formed at a large-film-thickness part. Thus, the high-refractive-index layer provided with the optical waveguide and the low-refractive-index layers are formed of the same semiconductor materials, and consequently the smooth reflection mirror surface can be formed by etching to reduce scattering, thereby obtaining the optical waveguide which has small loss and changes the traveling direction by 10 deg..
