Title: Treatment of waste water containing ammonium ion
Inventor: TAKEUCHI HISAO
IPC: C02F1/469
Filed: 1986-01-10
Abstract: PURPOSE:To remove ammonium ions by exchanging ammonium ions with hydrogen ions, by contacting waste water containing the ammonium ions with an aqueous mineral acid solution through a diaphragm being a cation exchange membrane. CONSTITUTION:A cation exchange membrane composed of a p-styrene sulfonate- divinylbenzene copolymer, a p-styrene sulfonate-butandiene copolymer or p- phenyl sulfonate-formaldehyde copolymer is used as a diaphragm to form a dialytic apparatus. Then, waste water containing 100-1,000ppm of ammonium ions is contacted with an aqueous mineral acid solution containing an inorg. acid such as hydrochloric acid or sulfuric acid. By this method, only the mineral acid from the aqueous mineral acid solution can be diffused and dialyzed and recovered to a water side and said solution can be used as a stripping liquid and the cost of the mineral acid can be reduced.

Title: Digital system simulation
Inventor: RAYNER JAMES EDWARD
IPC: G06F17/50
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To increase the simulation speed by providing a simulator with simulation models, an event queue, and a delta queue. SOLUTION: A model 12 in the highest level selects optimum forms of an event queue 13 and a delta queue 14 for the model and constitute respective queues. The event queue 13 generates a schedule of changes to be executed at specific points of time, and the delta queue 14 is used to generate a schedule of changes which seem to occur instantaneously. The simulator uses times simulated in two forms, namely, an event time, and a delta time. These two different time forms, namely, the delta time and the event time have queue forming operations different by forms and different optimizations, and therefore, independent event queue 13 and delay queue 14 are used to easily optimize queue forming operations.

Filed: 1990-01-12
Abstract: PURPOSE:To realize a power supply bus line optimal in impedance by a method wherein the power supply line wire is divided into narrow power supply line wires through the intermediary of slits, and the power supply line wires are adjusted in wiring width by filling the slit of the same layer with a wiring material basing on the ratio of number of circuits to which the line wires concerned supply power. CONSTITUTION:A power supply wiring 1 is made to serve as a TTL output bus line, and a power supply wiring 4 is made to serve as an ECL output bus line. Provided that TTL circuits are larger than ECL circuits in number, slit filling patterns 6a are filled into slits to enable power supply bus lines 1-3 to serve as the TTL output bus line. Therefore, the TTL output bus line becomes large in width, so that it can be decreased in impedance and made smaller in fluctuation of ground level when a TTL output terminal is switched from a high to a low level. By this setup, a power supply bus line optimal in impedance can be obtained.
