Filed: 1984-01-12
Abstract: PURPOSE:To manufacture directly the titled compound from wet process phosphoric acid in a high yield by bringing the phosphoric acid into a neutralization reaction with ammonia under specified reaction conditions, adjusting the pH of the reaction product to a specified value, separating formed sludge by filtration, and concentrating the filtrate to deposit crystals. CONSTITUTION:Wet process phosphoric acid is reacted with ammonia to obtain ammonium secondary phosphate or ammonium primary phosphate. At this time, the reaction temp. is kept at 70-110 deg.C, the reaction is continued for 30-180min, and the pH of the reaction product is adjusted to 4.2-6.5. Formed sludge is separated by filtration, and crystals are deposited in the filtrate by concn. to manufacture purified ammonium phosphate in a high yield. Conventional ammonium phosphate obtd. by reacting wet process phosphoric acid with ammonia contains much impurities, so it can be used as fertilizer but can not be used as industrial chemicals as it is. By this method, purified ammonium phosphate of industrial grade can be manufactured directly from wet process phosphoric acid in a high yield.

Title: Protecting device for motor drive system
Inventor: SAWA EIJI
IPC: G05B19/19
Filed: 1993-01-14
Abstract: PURPOSE:To avoid the danger of a motor drive system by actuating a motor at the largest torque and then reducing gradually the output of the motor in a dangerous state such as an overload state, etc. CONSTITUTION:The temperature of a motor 4 and the temperature of a power converter 2 are detected by the temperature sensors 30 and 31. These detected temperatures are compared with each set temperature by the comparators 35 and 36 respectively. If either one of both temperatures is higher than the set level, an overload state is decided. Then the limit level of a limiter 38 is varied based on the decision of comparison. In other words, the limit level of the limiter 38 is reduced at a fixed rate when the overload state is decided. Meanwhile the limit level is increased at a fixed rate. Thus the command signal for motor drive is limited by the change of the limit level.
