Title: Denitration
Inventor: SAKAMOTO TOKUO
IPC: B01D53/74
Filed: 1990-11-09
Abstract: PURPOSE:To suppress the exhausted NOx concentration lower and to suppress the discharge of NH3 by supplying the ammonia of a specified ratio of a stoichimetric quantity of ammonia necessary for the reduction of supplied nitrogen oxides and the ammonia of the quantity controlled by feeding back the nitrogen oxide concentration at the exit of the reactor to a reactor. CONSTITUTION:A treated gas from a treating gas source 1 is mixed with ammonia supplied from an ammonia source 2 and introduced to the reactor 3 to reduce the NOx in the reactor. The gas at the exit of the reactor is properly treated and exhausted. The NOx concentration at the inlet of the reactor is measured with a NOx analyzer 4 and the signal is transferred to a control section 7 and the theoretical quantity of NH3 necessary for the reduction reaction is calculated from the concentration of NOx at the inlet. On the other hand, the NOx concentration of the exit is measured with a NOx analyzer 5 at the reactor exit and the supplying NH3 quantity is calculated together with a theoretical quantity of NH3 and based on the value an NH3 flow rate regulating valve is controlled. By adopting this method, the NOx concentration at the exit is stabilized in a certain range, even through excess or shortage of NH3 occurs with uncertain elements such as NO/NO2 ratio, the flow rate variation of a treating gas, the analytical accuracy of the NOx meter.

Filed: 1991-11-19
Abstract: PURPOSE:To facilitate the control of an etching depth, to enable the reduction of the surface roughness of an etched surface and the formation of plural grooves of different depths with one time of etching. CONSTITUTION:An excimer laser oscillator 1 is arranged above a photosensitive glass plate 10 and the front surface 10a of the photosensitive glass plate is irradiated with an XeCl excimer laser 1a via an exposing mask 2. A laser of a pulse oscillation control type including the sensitivity wavelength region of the photosensitive glass is used for the laser. The energy intensity per pulse of the laser is specified to 80mJ/cm<2> and the front surface is irradiated with about 2 pulses. The total exposure is specified to about 160mJ/cm<2>. As a result, exposed parts 11 are formed on the front surface 10a but the total exposure is small and, therefore, the exposed parts are stopped at the prescribed depth from the front surface and the parts below these parts are non-exposed parts. Such photosensitive glass plate is heat treated to form crystal parts 11a and non-crystal parts 11b. Grooves of a prescribed depth are formed by etching in the crystal parts 11a. Since the base and both flanks of the grooves are the non-crystal parts, the surface roughness is small.

Abstract: PURPOSE:To prevent production of a slack on a sheet material by a method wherein a first and a second flapper are disposed on the same plane extending approximately at right angles with a sheet material to be conveyed, and the second flapper is held in a manner to make contact with the first flapper. CONSTITUTION:For example, during single-sided duplication, a sheet material on which a picture is formed by the passage of the sheet material through a first conveyance passage P1 enters through a first discharge roller 21 and a gap between a main and an auxiliary flapper 32 along a main flapper 31 shown by a solid line. the sheet material is moved toward a second discharge roller 22 on the second conveyance passage P2 as it pushes up the flapper 32 by a distance equivalent to the thickness of the sheet material. In this case, since all of a load exerted on the sheet material under gravity of the flapper 32 is supported by the flapper 31, the sheet material is conveyed approximately in a flat state without slacking in a waveform manner, and production of wrinkles and damage of a picture due to local excessive slide friction are prevented. Further, hooking of the sheet material by a corner part 31d at the tip of the flapper 31 can be reliably prevented from occurring during switch back.
