Title: Method and apparatus for denitrating exhaust gas
Inventor: INATSUNE YOSHIROU
IPC: B01D53/94
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for denitrating exhaust gas having good denitration performance even under the conditions in which severe NOx regulation is required during the actuation of a waste heat recovering boiler, and a method for operating the apparatus. SOLUTION: The time for starting the injection of ammonia during the actuation of a denitration apparatus is set up at a point of time when the temperature of a denitration catalyst layer part reaches the boiling point or the vicinity of the boiling point of the condensed water of exhaust gas. Since the reduction of NOx can be attempted even in a low temperature area without lowering the activity of the denitration catalyst, the discharge of NOx can be controlled during the operation of a plant.  Although an exhaust gas temperature at the outlet of the catalyst layer increases behind that at the inlet of the catalyst layer, when the injection of ammonia is started at 140 deg.C of an exhaust gas temperature at the inlet, an exhaust gas temperature at the outlet corresponds to 100 deg.C (the boiling point of the condensed water of exhaust gas), and since the temperature of the entire catalyst layer is at the lowest 100 deg.C when the injection of ammonia is started at this point of time, the discharge of ammonia or NOx into the air can be prevented.

Title: Checking circuit for write quantity of cell of nonvolatile memory
Inventor: MIYAMOTO JUNICHI
IPC: G11C17/00
Filed: 1985-02-13
Abstract: PURPOSE:To check the data readout margin of a cell accurately and to eliminate the need for a special external input terminal by varying the level of an external input signal without varying the potential of a Vcc power source and checking the quantity of writing. CONSTITUTION:When the quantity of writing is checked, a signal R is '0' and a signal -R is '1'; and a transistor (TR) 24 of a voltage dividing circuit 21 turns on and TRs 28 and 29 of a control voltage generating circuit 26 turn on. For the purpose, the level of a signal applied to a pad 30 is varied on analog basis to vary the current of a TR 27, thereby controlling the potential of a common output node 25 on analog basis. In this case, the potential of the Vcc power source is not varied. When a memory cell to be checked and a dummy cell corresponding to it are selected as well as in read mode and amplification is performed by a differential amplifier circuit to perform detection, the output voltage of the control voltage generating circuit 26 is varied on analog basis. Consequently, the data readout margin of the memory cell 1 can be checked.
