Abstract: PURPOSE: To provide a fuel injection system of a simple and economical structure, which is capable of supplying well-atomized mixture to a plurality of cylinders by use of a common fuel injection valve.  
     CONSTITUTION: A Karman vortex flow meter is designed to measure fluid flow rate by detecting flow caused in thru-hole 3 each time vortex is produced by vortex generating means 2 disposed in fluid as resistance change of hot wire 4 and thereby measuring its frequency or period of vortex generation. Therefore, if such a Karman vortex flow meter is used as sensor for detecting flow rate of suction air and fuel is injected to the area where fluid flow is disturbed by the Karman vortices, fuel is well mixed with air and a mixture containing highly atomized fuel can be obtained. In the arragement of this invention, nozzle 15 of fuel injection valve 14 is opened at a downstream side of vortex generating means 11 to inject fuel to the portion where fluid flow is highly agitated by Karman vortices, so that fuel is supplied to cylinders after it is well mixed with suction air from suction port 7.

Title: Automatic tracking device
Inventor: TERADA TOSHIYUKI
IPC: H04N7/18
Filed: 1994-06-03
Abstract: PURPOSE:To provide an automatic tracking device which can track even an object moving at a low speed by selecting the rewriting operation of the contents of a memory that stores the luminance signal of the moving object based on the moving state of the object and by controlling the tracking of the object when the total of fine moving amount of the moving object exceeds a single block unit. CONSTITUTION:A CDS circuit 2 samples the electric signals received from an image pickup element 1 and transmits an image pickup signal. Thus pickup signal is converted into a digital signal by an A/D converter 3, and a line memory 4 fetches in sequence the luminance signals Y equivalent to a single line in a fixed video signal extracting area that is equivalent to a single screen of the signals Y. Then a memory 6 included in a CPU 5 fetches a new signal Y for each field of a moving object. Meanwhile a memory 7 fetches the signal Y preceding by a single field before movement of the object. A correlative function is calculated to the data showing the arithmetic parts divided equally into a prescribed number of blocks stored in the memory 7 before and after movement of the moving object. Then a shift position showing the highest correlativity is detected through the complementary correlation. The tracking control of the moving object is possible when the accumulation of fine moving amount of the object exceeds a single block unit.

IPC: F03B15/04
Filed: 1982-07-14
Abstract: PURPOSE:To permit to restrict the revolving speed increase of the water wheel and a generator upon interrupting a load at a low rate by a method wherein a guide vane is closed totally and a runner vane is fully opened quickly simultaneously with the interruption of the load of the valve water wheel. CONSTITUTION:In the water wheel having variable opening degrees of the guide vane and the runner vane, and guide vane 11 is fully closed simultaneously with the interruption of the load, as shown by a broken line in the diagram (a). On the other hand, the runner area vane 12 is fully opened rapidly simultaneously with the interruption of the load, as shown by a broken line in the diagram (b). According to this method, the flow amount of water flowed through the water wheel is somewhat increased compared with a conventional decreasing method, however, a water wheel efficiency is decreased and the loss of the water wheel is increased, thereby enabling to prevent the increase of the revolving speed. As a result, the increasing value 13 of the revolving speed of the water wheel generator becomes about 40% of the maximum increasing value DELTAn, as shown by the broken line in the diagram (c) and may be reduced lower than the value in the conventional method.
