Abstract: PURPOSE:To unify the quantity of NOX and CO generated, by a mthod wherein, in the titled device provided below a dispersion plate with an air chamber partitioned by the dispersion plate located at the bottom of a fluidized bed, the inside of an air chamber is divided into an air feed chamber with a high oxygen partial pressure and an air feed chamber with a low oxygen partial pressure. CONSTITUTION:In a fluidized bed device 1, a fluidized bed 4 is formed above a dispersion plate 2 located at the bottom thereof, and a heat transfer pipe 5 is installed within the fluidized bed 4. A part below the dispersion plate 2 forms an air chamber 11. In which case, a partition 19 divides the air chamber 11 into an air feed chamber 20 having a high oxygen partial pressure and an feed chamber 21 having a low oxygen partial pressure. Exhaust gas in a flue duct is guided into the air feed chamber 21 through a gas circulating duct 22, and meanwhile, the air passing through a preheater is guided into the air feed chamber 20 through an air duct 10. This suppresses combustion at the center of a furnace through the supply of inactive gas (exhaust gas) from the air feed chamber 21 to the center of the furnace, and reduces the production of NOX by means of CO, HC, etc. generated as a result of pyrolysis of coal.

Title: Slot waveguide for slot array antenna
Inventor: TERAKAWA TAKANARI
IPC: H01Q13/22
Filed: 1978-08-07
Abstract: PURPOSE:To exclude the phase error and to improve the array effect, by drilling in the notch to the wide surface of a rectangular waveguide so that it is made with the same slope angle as the slot slope angle to the narrow surface of the rectangular waveguide toward the orthogonal direction to the guide axis. CONSTITUTION:The slot 3 is made on the narrow surface 4 of the rectangular waveguide 1 in a slope angle of theta, and the notch to the wide surface 5 is made with the slope angle theta to the direction orthogonal to the guide axis. The guide wall current by TE10 mode flowing in and out to the slot 3 has a slope angle of theta on the narrow surface 4 and flows to the slot 3 with the slope angle theta the same as the case with the narrow surface 4, if the depth D of notch is small at the wide surface 5. Accordingly, the slot 3 makes the same operation as the slot excited with the current flowing on one plane unidirectionally. Thus, the slot 3 contributes to the excitation due to the guide current flowing to the wide surface 5 and can improve the array effect by increasing the slot conductance.

Abstract: PURPOSE:To enhance the rate of utilization of manganese dioxide and attain high capacity by furnishing a positive electrode black mix in which sticky powder is in gaseous phase quickly mixed with and dispersed in manganese dioxide with conductive powder fixed to its surface layer. CONSTITUTION:A black mix is prepared by quickly mixing and dispersing PTFE powder 3 as sticky powder in gaseous phase with/in manganese dioxide 1, in whose surface layer carbon powder 2 as conductive fine powder is dispersed uniformly and fixed, and a certain amount of this black mix is taken out and subjected to pressure molding into pellets to accomplish a positive electrode. This enlarges the contact frequency between the manganese dioxide 1 and carbon powder 2, and during discharge, supply of electrons to the manganese dioxide 1 is performed smoothly, so that the rate of utilization of manganese dioxide 1 is enhanced to cause increase in the discharge capacity. As the black mix does not contain any interface activating agent easy to adsorb water owing to accomplishment of dry mixing of the PTFE powder 3 solely, the storing characteristic is enhanced, and further the manufacturing processes can be reduced.
