Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of an equipment and a chemical agent for removing calcium and reduce the amount of use of the chemical agent for preventing scale troubles by computing the target pH of a nitration tank based on the measurement of the M-alkaline strength and the Ca concentration in a nitration tank and adjusting pH in the nitration tank based on the computed result. SOLUTION: The Ca concentration and the M-alkaline strength in a nitration tank 1 is measured by a Ca concentration and M-alkaline strength analysis device 12. The measurement result of the analysis device 12 and the measurement result of a pH meter are input into a computation controller 13, and the computation is performed in compliance with a computation formula based on the above measurement values, and pH in the nitration tank 1 is controlled based on the computation result. The scale troubles in a system can be prevented by the arrangement. An equipment for removing calcium, therefore, is not necessary, and a device can be smaller in size. Also a chemical agent for removing calcium is not necessary to reduce the chemical agent cost. The formula is that the supersaturation = nitration tank target pH-[1.99-(log(Ca concentration/40/1000)+log(M-alkaline strength/100/1000)}].

Filed: 1992-05-29
Abstract: PURPOSE: To enable discriminating the most dangerous head-on collision from other collision, by making a human support system execute a desired action, when the difference velocity of a vehicle obtained by a computer exceeds a threshold value. CONSTITUTION: An acceleration sensor, e.g. piezoelectric sensor, of a measuring equipment 10 detects acceleration (which is negative, here). An estimation equipment 11 is provided with an A/D converter 12, a subtracted 15 and a threshold value switch 16. The velocity V of a vehicle is calculated by integrating the acceleration by a time part dt of equal interval, in a constant time interval, and stored in a storage device 14. The velocity V is reduced by subtraction of the time part using the preceesing speed. When the calculated difference speed ΔV is greater than or equal to the threshold value ΔVs, a human support system executes desired operation on the basis of a signal from an operating circuit 17. This method is performed by simple algorithm which can be stored in a microcomputer or a microprocessor.  The threshold value can be freely adjusted and espeially increased.

Abstract: PROBLEM TO BE SOLVED: To enhance the precision of detecting the movement of an object by excluding the object which moves in a monitor area in a short time concerning a monitor camera. SOLUTION: A video signal from an image sensor 1 is digitized by an A/D converter 2 and stored in a frame memory 3a and a background image being the reference is stored in a frame memory 3b.
