IPC: B01D53/56
Filed: 1979-10-31
Abstract: PURPOSE: To simply save the amount of fuel by a method wherein part of waste gas containing unburnt component is jetted into the heating furnace as a diluting gas and mixed with combusted gas, and the mixed gas is mixed with the remaining waste gas and heated to a temperature of denox reaction.  
     CONSTITUTION: A combusting oxygen source such as air or waste gas is used as a fuel for combustion. This combusted gas is projected from the burner 13 in the combustion chamber 11, and part of waste gas containing unburnt component such as Co or hydrocarbon, e.g., sintered waste gas, is injected from the branch duct 17 as a diluting gas. As a result, the temperature of the combusted gas is decreased and at the same time the unburnt combponent in the diluting waste gas oxidizes and generates heat. In this process, a preferable condition is a combusted gas temperature at 750W1,000°C which is maintained by controlling the amount of diluting gas with the flow damper 18, and a gas staying time in the combustion chamber 11 maintained at 0.5W1sec. Then, the mixed gas is guided to the mixing chamber 12 through hot draft duct 14 to be mixed with the remaining waste gas from the duct 15, and the mixed gas is raised to about 400°C, or denox reaction temperature, and is guided through duct 16 into the denox reactor.

Abstract: PURPOSE:To charge electrostatically high-resistance toner to a high level and to obtain a visible image of stable high quality, by providing a magnetic field producing means of establishing at least an AC magnetic field between the AC and DC magnetic fields at an opening. CONSTITUTION:A photoreceptor 1 positioned facing the opening 9 of a container 4 is driven to rotate, for example, counterclockwise and a latent image forming device forms an electrostatic latent image of the surface of the photoreceptor. As the photoreceptor 1 rotates, toner charged to specific polarity, e.g. opposite to the polarity of charges of the latent image separates from magnetic material powder and moves to the latent image where the latent image faces the opening 9, making the latent image visible. This visible image itself is transferred to transferring paper. Then, toner as much as the toner moving to the photoreceptor 1 is supplied from the container 4 to surfaces of particles 18 successively and charged by the vibration of the particles 18. In this case, the toner is stuck to each magnetic substance particle 18 preferably in a very thin layer to improve the picture quality of the visible image formed of the toner.

Abstract: PURPOSE:To narrow the width of an active layer under satisfactory controllability, and to suppress a decrease in the yield due to step cut in the case of a buried epitaxial layer, a buried leakage, etc., due to narrowing by forming the outside of a double channel in a forward mesa and an inside, i.e., a mesa stripe to become a light emitting unit vertically or in a reverse mesa shape. CONSTITUTION:A mesa stripe 9 including an active layer 3 and double channels 100 at both sides of the stripe are formed by etching to a part underneath the layer 3 with mixture solution of HCI:H2O2:CH3COOH. Here, an SiN film 21 to become a mask is deposited directly on a P-type InP clad 4 at the stripe 9 disposed at the center of the channel 100, while an SiN film mask 21 exists on a P-type InGaAsP cap layer 20 outside the double channel. Here, the close contact of an InP/SiN with etchant of (chloric acid + hydrogen peroxide) is excellent, side etching is small, and the stripe 9 at the center becomes a reverse mesa shape, but since a region formed through the region 20 has a higher etching speed of InGaAsP than that of InP, the side surface outside the channel becomes a forward taper.
