Abstract: PURPOSE: To accomplish the removal of ammonium from waste water at a lower cost without any secondary pollution through extraction of ammonium absorbed by zeolite with a solution of sodium chloride and the like and a subsequent stripping thereof under a reduced pressure.  
     CONSTITUTION: Water in a storage tank 1 is fed into a packed tower 4 through a filter 2 to absorb ammonium ions therein by zeolite packed in the tower 4. Then, with the actuation of pumps P2 and P3, a solution of sodium chloride and sodium hydroxide in storage tanks 5 and 6 is circulated in the coruse of the tower 4, the pump 6 and the pump 5. Thus, the ammonium absorbed by the zeolium in the tower 4 is taken into the solution as ammonium ions. Then, the solution is circulated in the course of the tank 6, a heat exchanger 10 and a stripping tower 8 with the actuation of a pump P4, and then, a vacuum pump 11 is actuated. Consequently, the ammonium in the solution undergoes stripping by drop in pressure of the tower 8. The ammonium thus stripped is fed to a pyrolysis furnace 12 through the pump 11 to be separated into hydrogen and nitrogen. The hydrogen thus separated is burned in a combustion furnace

Title: Circuit for compensating distortion of multivalue quadrature amplitude modulated wave
Inventor: SUMI TOMOYA
IPC: H04J11/00
Filed: 1993-04-21
Abstract: PURPOSE:To fix the open loop transfer function of a feedback loop regardless of gain control of transmission power by permitting a control part to control a first attenuator so that the open loop transfer function of the feedback loop is always fixed in correspondence to the changing quantity when a second attenuator changes the gain of transmission power. CONSTITUTION:The second attenuator (ATT) 42 is provided for the input stage of AMP 3 of a circuit for compensating the distortion of a multivalued quadrature amplitude modulated wave to control the gain of transmission power. A control part (CT) 10 controlling feedback control use ATT 41 corresponding to the contents of changing control executed from the outside of this gain control use ATT 42 is provided to prevent the feedback loop from becoming unstable. Namely, when the attenuating quantity of ATT 42 is increased and transmission power from an output terminal 7 is reduced by external operation, CT 10 reduces the attenuation quantity of ATT 41 and increases a feedback quantity. When the attenuating quantity of ATT 42 is operated for reduction on the contaries, the attenuating quantity of the ATT 41 is increased and the feedback quantity is suppressed. Thus, control operation is executed so that the complete transfer function of feedback loop is always fixed regardless of the gain control of transmission power.
