Title: Combustion control device
Inventor: KOYAMA YOSHITOSHI
IPC: F23N1/02
Filed: 1989-11-10
Abstract: PURPOSE:To prevent abnormal combustion from taking place by providing a flame detecting element to detect flames of a burner to control speed in the case of variation of output of a fan motor and a proportional valve in response to detected values from the flame detecting element when number of revolution of the fan motor and opening of the proportional valve decrease. CONSTITUTION:A flame rod 8 serving as a flame detecting element to detect flames of a burner 7 is connected to an outdoor control device 6 through a flame current detecting circuit 9, while an indoor control device 5 is connected to the device 6 to receive command from a control part 4 and further a burner motor control circuit 10 and a proportional valve control circuit 11 are connected to the device 6. Air-fuel ratio is controlled using functions to increase or decrease, by certain proportion, number of revolution of a DC motor 12 and opening of a proportional valve 13 by means of the device 6. When the number of revolution of the motor 12 and the opening of the valve 13 are reduced by certain proportion, decreasing speed is slow and hence unbalance, i.e., excess of air, due to either the fan motor or the proportional valve is eliminated, so that flame condition becomes stabilized, avoiding thereby abnormal combustion such as blow-off or back fire.

IPC: G06F17/50
Filed: 1987-11-20
Abstract: PURPOSE:To remarkably shorten a processing time by executing a tracing processing successively in a straight proceeding direction before and after a branching point and executing folding line transform processing by using tracing point information. CONSTITUTION:A picture element string PX of data 42 is scanned and the black picture element PS of a tracing starting point is detected and stored to a memory 50 as data 51.

Next, the direction D0 and a minimum direction D1 of direction difference are obtained and the size of the direction difference between the direction D1 and another direction D2. When the direction difference between the directions D1 and D0 is minimum, decision is made as almost straight processing direction. When the direction difference between the directions D1 and D0 is large, the decision is made as the branching point and the tracing of the picture element string is finished. By executing the folding line transform processing with respective tracing information TR1 and TR2, even in the branching point, the data of folding lines L1 and L2 to be successive in the straight proceeding direction can be obtained and one processing to connect the folding line later can be omitted. Then, the processing time is wholly shortened.

Title: Method for purifying exhaust gas in melting type municipal incinerator
Inventor: SATO TAKERO
IPC: F23J15/02
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To remove by adsorption hazardous substances contained in exhaust gas by separating and collecting char contained in combustible gas produced by a melting furnace and blowing the char into the exhaust gas after the combustible gas has been subjected to combustion treatment. SOLUTION: Gas produced in a furnace 1 is a combustible gas containing carbon monoxide, hydrogen and hydrocarbon. Because of an atmosphere which contains almost no oxygen the char thus generated contains a large amount of carbon. The char is composed of carbonized paper, wood and garbage in crude waste, which have been formed by subjecting to carbonization and scattered by an ascending gas within the furnace. Almost all of the char is collected by a cyclone 2. The char has fine holes and a specific surface and functions as an adsorbent by increasing the amount of usage. The char is blown through a blowing position where temperature of gas is 30 deg.C or lower and contaminants on a surface of the char is not evaporated. The contaminants on the surface of the char is removed and purification of exhaust gas is implemented.

IPC: G09G3/294
Filed: 1990-10-31
Abstract: PURPOSE:To prevent mistakes in discharge by applying to the cathode of a display cell a pulse train of the same width as a writing pulse and the same interval as maintaining pulses, and lowering the voltage between the cathode and a display anode. CONSTITUTION:During the period from the application of a scanning pulse to a cathode kj to the application of an erasing pulse, a pulse of the same width tauw as a writing pulse applied to a display anode Dj and the same period T as a maintaining pulse is superimposed on the potential Vo of the cathode kj. In order to cancel the writing pulse, the amplitude Vwe of the pulse should desirably be as near as the amplitude Vwp of the writing pulse. When the base potential of the display anode Dj is Vb(bias potential) the voltage between both of the electrodes when the writing pulse is applied with the timing different from that of the scanning pulse is Vwp + Vb - Vwe. When the amplitude Vwe is equal to the amplitude Vwp the voltage between both of the electrodes is Vb and there is no possibility of mistakes in discharge even with the maintaining pulse which is subsequently applied.
