Abstract: PURPOSE:To remarkably reduce flocculation, to enhance scattering into the waste fossil fuel combustion gas and to compeletly preventing trouble due to sulfuric acid in the waste gas by coating the surfaces of the grains of MgO and CaO with a specified liq. organosilicic compd. CONSTITUTION:A liq. organosilicic compd. (its amt. controlled to 0.2-2.0wt.% based on MgO or a mixture of MgO and CaO) such as dimethylhydropolysiloxane and methylmethoxypolysiloxane is brought into contact with the grains of MgO and CaO (the content controlled to <=30wt.%) and chemically adsorbed on the surfaces of the grains. Consequently, the grains are coated with the monomolecular layer of the organosilicic compd. When the coated grains are scattered in the waste fossil fuel combustion gas, the flocculation of the grains is remarkably reduced, the fluidity is increased, the movement as the single grain is facilitated, and the scattering property is remarkably enhanced. As a result, trouble due to the sulfuric acid in the waste gas is completely prevented.

Title: Oil surface detection system
Inventor: TSUJI HIROYUKI
IPC: G01F23/22
Filed: 1986-12-01
Abstract: PURPOSE:To exclude errors due to the thermal diffusion coefficient of a temp.-sensitive element, by allowing the temp.-sensitive element to generate heat itself not only in the case of obtaining threshold value but also in the case of obtaining a comparing value. CONSTITUTION:At first, temp. is detected at a b-point. That is, the voltage VP at a P-point is converted to a digital value by an A/D converter 7 to be stored in RAM 9. When this detected temp. is the first one, the measurement of a time T2 is started and a transistor (TR) 4 is turned ON to allow a temp.-sensitive element 1 to begin to generate heat itself and the heat self-generation temp. of the temp.-sensitive element 1, that is, the voltage VP at the P-point to be converted to a digital value by the A/D converter 7 and predetermined operation is performed to convert said digital value to a threshold value. next, this threshold value is stored in RAM 9 and the measurement of a time T1 is started and, during this time, TR 4 is turned OFF to finish the self-generation of heat. After the elapse of the time T1, the same operation as that performed heretofore is performed and, when it is judged that the detected temp. is not the first one, the measurement of the time T2 is started and TR 4 is turned ON to allow the element 1 to start the self-generation of heat. After the waiting of the time T2, the voltage VP at the P-point, that is, the self-generation heat temp. is detected at an a-point to be converted to a digital value by the A/D converter 7 and this comparing value is compared with the threshold value previously stored. For example, when threshold value > comparing value is formed, it is judged that there is no oil.
