Title: Image reader
Inventor: NAGASE MASAAKI
IPC: H04N1/40
Filed: 1987-04-20
Abstract: PURPOSE:To set the optimum threshold value level automatically without necessitating complicated adjustment, by providing a measuring means which measures the density distribution histogram of an original read signal, and a means which stores and sets a binarized threshold value level corresponding to the output of the measuring means. CONSTITUTION:The titled device is equipped with a circuit 2 which reads an original on which the frame designation of a mark position, etc., is applied by a dropout color and measures the histogram of density from the original read signal (a) to remove a frame, and a circuit 3 which stores and sets the binarized threshold value level corresponding to the original read signal (a). And a picture signal (a) is obtained by reading the original on which no information is written, and the histogram of the density is measured from the picture signal (a), then, the optimum threshold value level is set corresponding to a measured result. Thus, it is possible to set a binarized threshold value to remove the dropout color automatically and surely at one time of easy operation.

Title: Automatic gearshift controller for automobile
Inventor: NAJIMA HIROHISA
IPC: B60W10/06
Filed: 1985-05-09
Abstract: PURPOSE:To reduce a shift shock without entailing any increase in a heating value of shift elements including a brake band and so on, by regulating engine output so as to come nearer to output after the shift timing, at the time of gearshifting. CONSTITUTION:A controller 13 judges the shift element of a transmission by each signal out of a throttle sensor 14 and a car speed sensor 15 and thereby outputs at operating signal to each of solenoid valves 12A-12E whereby coupling and release of each shift element are carried out. In addition, the controller 13 outputs a fuel-cut signal to a fuel injection controller 18 for the specified time long when it judges as gearshifting time. With this constitution, while the fuel-cut signal is inputted, the output of an injection pulse signal to a fuel injection valve 17 is stopped and fuel injection is also stopped. Therefore, even if a difference in revolving speed between both engine and driving wheel sides is large, a part of the turning energy is absorbable at the engine side, thus a shift shock is reducible.

Title: Fuel injection valve for internal combustion engine
Inventor: SOGAWA TOSHIO
IPC: F02M47/02
Filed: 1978-08-09
Abstract: PURPOSE: To provide a simple construction and gradually rising up injection rate characteristic, an accumulator is provided in the nozzle spring chamber, and an orifice between the nozzle spring chamber and the accumulator.  
     CONSTITUTION: Pressure in the nozzle spring chamber 11 can be changed by throttling effect by properly determining the diameter d of the orifice 18 installed between the nozzle spring chamber 11 and the accumulator 14. This adjusts the capacity of the accumulator 14 to absorb the pressure increase in the nozzle spring chamber 11. Thus, this construction works against the load of the nozzle spring 9 as well as the pressure in the nozzle spring chamber 11 for valve needle 2 opening motion. This provides gradual injection rate rise-up characteristic when fuel feed is increased, effecting reduced combustion noise.

IPC: H04B3/23
Filed: 1981-06-24
Abstract: PURPOSE:To improve the converging characteristics of an echo canceler, by using a recursive filter at the inside of the echo canceler. CONSTITUTION:A reception signal inputted from an input terminal at the reception side is transmitted to a terminal device 7 through an output terminal 4 at the reception side and a hybrid coil 6. A part of a reception signal passes through the coil 6 and enters an input terminal 5 at transmission side as an echo. The reception signal is transmitted to a recursive coefficient calculator 9 and a forecast device 10 at the inside of an echo canceler 1 via a register 8. The recursive coefficient obtained at the calculator 9 is transferred to forecast devices 10, 14, and 19. A convolutional operating device 13 performs convolutional operation for the signal in a register 2 and a residual signal of a subtractor 11. An adder 19 forms a virtual echo and a subtractor 20 subtracts an output of the adder 19 from the echo signal to eliminate the echo.

Abstract: PURPOSE:To prevent swing of a consumable nozzle at the time of welding by forming a flux ring for preventing swing so as to have shape which is made by mixing and harding a flux material and binder material and prevents swing of the consumable nozzle by approaching to both base materials. CONSTITUTION:The consumable nozzle 24 is inserted at between both base materials 10, 12 to be welded and a welding wire passed through the nozzle 24 is fed to execute the welding. At this time, as the consumable nozzle 24 is under cantilever state with only upper part fixed, the tip part thereof is easily swung. However, prior to swing of the consumable nozzle 24, anyone of four projections 44 in the flux ring 40 is brought into contact with the base material 10, 14 to prevent swing of tip part in the consumable nozzle 24. By this method, as the welding wire guided in the consumable nozzle 24 is accurately positioned at center of both base materials 10, 12, the development of imbalance to melting of both materials 10, 12 can be prevented.
