摘要： PURPOSE:To obtain stable, highly reliable solution by using a container, which can be tightly sealed, and providing an agitating mechanism for the solution in the container and temperature and water-quantity controlling mechanisms. CONSTITUTION:When a tightly sealed container 2 is heated to a constant temperature, the internal pressure in the container rises up, and the boiling point of the solution in the container 2 rises up at the same time. At this time, the chemical reaction between a sample to be analyzed 12 in the continer 2 and mineral acid 11 is accelerated at the speed twice the speed under the atmospheric pressure. The gas, which is evaporated and generated from the heated mineral acid 11, is dissolved into the solution again by the action of the inner pressure of the container since the tightly sealed container 2 is used. The gas is not discharged to the outside of the container. In the agitation in the container 2, the sample 12 is uniformly dissolved into the entire mineral acid 11 by the agitation of the sample 12 and the mineral acid 11 in the container 2 all the time. Thus, the generation of sediment is prevented, and the optimum solution for analysis is obtained.

摘要： PURPOSE:To discharge pulverulent materials without choking at the sides of a tank, by providing a discharge opening at the lower part of the tank and setting the bottom face of the tank and the whole crossing lines of the bottom face with the side faces on slanting planes or curved face slanting down toward the discharge opening. CONSTITUTION:A discharge opening 4 directing to the outside is equipped at the lower part of the side face 2 of a container 1. The bottom face 3 of the container and the whole crossing lines of the bottom face 3 with the side faces 2 are designed so that these are on an inclined plane or curved face going down to the discharge opening 4. In this structure, the stored pulverulent material flows down toward the discharge opening 4 along the inclination of the bottom face 3 by its own gravity. The pulverulent materials are discharged without bridging, since the load right before the discharge opening 4 is different, depending on the direction. The inclination theta of the bottom face 3 ranges should preferably be 10-45 deg. in this case.
