Title: Treatment for waste gas of coal combustion
Inventor: ITOU HAYAMIZU
IPC: B01D53/77
Filed: 1981-08-31
Abstract: PURPOSE:To prevent the corrosion and clogging of an air preheater owing to the formation of NH4 salt by adding Ca(OH)2 slurry into the high-temp. waste gas between a dry denitrator and the air preheater and adsorbing away the SO3 in the gas. CONSTITUTION:The waste gas from a coal firing boiler 1 is conducted to a high- temp. electric dust precipitator 2, where the gas is removed of dust. After NH3 is added through a supply pipe 3, the gas is conducted into a denitrator 4, where NOx is converted to N2 and H2O. At the same time, part of SO2 is converted to SO3. In succession, the waste gas is introduced into a spray dryer 5. When Ca(OH)2 slurry is supplied into the gas and is allowed to react with the SO3 in the gas in the dryer 5, gypsum is formed; at the same time, the slurry is dried by the high-temp. waste gas to fine powder. The waste gas is conducted through an air preheater 7 and a gas-gas heat exchanger 8 into a wet desulfurizer 9, where the gaseous SO2 and said fine powder are removed. Thereafter the gas is released through a chimney 10.

IPC: F23N5/12
Filed: 1984-07-04
Abstract: PURPOSE:To prevent the extinguishing of fire due to the malfunction of a combustion detecting device by a method wherein dewing on the surface of porcelain for the flame rod is prevented in the initial stage of combustion to prevent the temporary reduction of the current value of the flame rod. CONSTITUTION:The flame rod 3 for a secondary combustion chamber 2 is attached through a mounting fitment 4 so that the porcelain 3a thereof does not contact directly with the combustion chamber 2. The mounting fitment 4 is a tubular body and is formed with small holes 4a on the upper and lower parts thereof and a path 4b, communicated with the small holes 4a and including a part of the porcelain 3a.

Title: Subscriber circuit of telephone set
Inventor: HIYAMA KUNIO
IPC: H04Q1/32
Filed: 1982-08-11
Abstract: PURPOSE:To decrease the load of a processor, by providing a counter counting the change in a line signal in a subscriber circuit and counting the change in the signal with the hardware. CONSTITUTION:A line signal LS is inputted to an FF6 and the output of the FF6 is inputted to an FF7. Logical gates 11, 12 detect that the values of the FFs 6, 7 are the same and an FF8 is operative accordingly. For example, suppose that the period of a clock signal CK is 2ms, when the signal LS within 2ms is changed, the content of the FFs 6, 7 is not the same and no signal is outputted from the gates 11, 12. Thus, even if a short pulse due to the chattering enters the signal LS, it is eliminated. Then, the number of dial pulses is counted by inputting an output of the FF8 to a counter 9. On the other hand, a processor 1 fetches the content of the FF8 and counters 9-1-9-4 by transmitting a specific address to an address bus 2.

Title: Deviation correcting system for running sheet
Inventor: CHIYOU HIDEYUKI
IPC: B65H23/032
Filed: 1978-11-09
Abstract: PURPOSE: To precisely correct bit by bit a deviation of a running sheet, by changing the angle of a guide roller as a result of the guide roller being rotated in a deviation correcting direction through the working of a deviation detecting mechanism, and  simultaneously, by causing the detecting mechanism to be moved following in the wake of a deviation direction of the edge of the running object.  
     CONSTITUTION: An endless belt R is placed vertically passing around guide rollers 2 and 3. If the belt R is displaced to a deviation detecting mechanism 6 while the belt is running in the condition described above, the displacement of the edge of the belt results in pressing outward a touch lever 8 against a spring 9. As a result, a flow passage in a valve system 7 is switched, a piston rod 13 of an air cylinder 13 being then moved backward by virtue of compressed air from a compressed air source. Consequently, a fixing stand 4 whereon two rollers 2 and 3 are situated is rotated counterclockwise about an axis 5, the deviation correction of the belt, thus, being performed. Simultaneously, the detecting mechanism 6 is rotated outward centering around a rotatably-fixing part 11 serving as a fulcrum through the medium of a crank system 10, the detecting mechanism 6 being displaced following in the wake of the deviation direction of the edge of the belt R. Thus, the detecting mechanism 6 completes arrangements for subsequent detecting.

Abstract: In order to limnit the exhaust particulate emission when supercharging a pressure wave machine-supercharged internal combustion engine, an exhaust particulates filter is arranged in the high-pressure part of the exhaust gas system ahead of the pressure wave machine. By increasing the supply of fuel to the engine itself and/or briefly closing a charge air flap valve a recirculation flap valve and/or brief opening of a exhaust gas by-pass valve, the exhaust gas attains the combustion temperature of soot components deposited on the surface of the filter. These soot components are burned off, and the filter is automatically regenerated.
