Title: Method for analyzing ethylenediaminetetraacetic acid
Inventor: HAMADA NAOKI
IPC: G01N30/06
Filed: 1988-12-29
Abstract: PURPOSE:To decrease the concentration of salt in a moving phase and to make it possible to perform detection so as not to shorten the life of an apparatus by using a material wherein specified quantities of tetrabutyl ammonium and organic solvent are mixed to the specified quantity of buffer at a specified concentration as the moving phase. CONSTITUTION:In a moving-phase tank 3, the following material is contained as a moving phase: a material wherein 2-30-millimol tetrabutyl ammonium and 5-30% organic solvent are added in phosphoric acid buffer solution whose hydrogen ion concentration is adjusted at pH 3-8. Transition metal ions are added into a specimen solution to be analyzed, and the specimen which is transformed into the chelate of iron-ethylenediaminetetraacetic acid is prepared. When the specimen is injected into a specimen injecting mechanism 2, the chelate is subjected to the action of the organic solvent in the moving phase and the tetrabutyl ammonium. The specimen is separated in a reverse-phase distributing column 1 which is filled with a filler whose functional group is octadecyl group. Light absorption occurs, and a sharp peak is generated. Ultraviolet-ray absorbance is measured 4 based on the peak.

Title: Constant current circuit
Inventor: SHIBUYA NAGAHISA
IPC: G05F1/10
Filed: 1988-12-30
Abstract: PURPOSE:To obtain the output of a constant current which is changed slightly with a constant voltage by generating a voltage difference to a constant-voltage which is slightly changed with the output of an operation amplifier on both sides of a constant current setting resistor, and outputting a constant-current in proportion to an input voltage. CONSTITUTION:A constant voltage, an input voltage, and each resistance value of resistors 4-9 are denoted as V1, V2, and R4-R9, respectively, and the resistance value of a constant current setting resistor 3 is denoted as R3. The output terminal voltage Vop2 of an operation amplifier 2 is shown by an expression I. Also, R6/R7=R8/R9=beta, and also, the resistance values R6-R9 is larger enough than the resistor 3, and comparing with a constant current outputted through the resistor 3, a current flowing to the output terminal of the amplifier 2 through the resistors 8, 9 can be disregarded. As a result, a constant current Iout outputted through the resistor 3 becomes Iout=beta.Vop2/R3 and shown by an expression II. Consequently, by selecting suitably values of the resistors 4 and 5, the output of a constant current which is changed slightly in proportion to an input voltage fluctuated arbitrarily can be obtained.

IPC: F02M47/00
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To avoid generation of negative pressure in a fuel injection pipe line by providing a pressure accumulator mechanism having a subsidiary chamber communicated to a fuel reservoir and having a fixed capacity, a piston facing to the sub-camber and holding the subsidiary chamber at fixed pressure, and a spring. SOLUTION: Fuel is gradually pressurized from a fixed injection beginning crank angle, and reached to a fuel reservoir 2 through an injection pipe and a fuel passage 4. Pressure in the fuel reservoir 2 is applied to a needle valve 3, and when it exceeds the valve opening pressure, the needle valve 3 is opened and fuel in the fuel reservoir 2 is injected from a nozzle 5 into the combustion chamber of an engine. After injection, when the pressure in the fuel reservoir 2 is lowered under the valve opening pressure of the needle valve 3, the needle valve 3 is closed, and simultaneously pressure wave is generated between a fuel injection pump and the fuel reservoir 2 of a fuel injection valve.  The pressure wave becomes large at the fuel reservor 2, reaches a subsidiary chamber 7 through a communicating hole 11, and when the pressure wave is lowered nearby negative pressure, a piston 8 provided in the subsidiary chamber 7 is pushed down by a spring 10, fuel in the subsidiary chamber 7 flows out into the fuel reservoir 2, and hence positive pressure is held.
