IPC: G01N31/00
Filed: 1990-04-26
Abstract: PURPOSE:To make measurement down to a low concn. by adding tributyl phosphate and an org. solvent to a acidic soln. of hydrochloric acid and adding water or <=4N mineral acid thereto. CONSTITUTION:An operation is carried out in a clean bench as far as possible. Aluminum or the alloy thereof is generally dissolved by an aq. soln. of hydrochloric acid. The solvent mixture composed. of the tributyl phosphate and the org. solvent is added thereto to extract and separate uranium and thorium. The soln. is adjusted to about 8 to 11N, more preferably about 9 to 11N hydrochloric acid-acidity. The extracted solvent mixture is separated from the dissolved aluminum soln. and is then brought into contact with the water or about <=4N mineral acid to migrate the uranium, thorium, etc. The extraction liquid after the contact treatment is separated by a resting method, etc., and can be measured by an induction coupled plasma mass analysis method. Further, the extraction liquid is heated and concd. at <=100 deg.C, more preferably <=95 deg.C to a constant volume and is measured, by which the analysis of the trace level is executed.

Title: Signal transmitter
Inventor: AZEGAMI TADASHI
IPC: G06F3/00
Filed: 1981-07-17
Abstract: PURPOSE:To realize a long-distance transmission of signal, by eliminating the effect of the electrostatic capacitance caused between a driving line and a reference line and the effect of common impedance. CONSTITUTION:A capacitor 17 having sufficiently larger value than interline electrostatic capacitance is connected between a reference line 3 and a common 9 at a termination part 1. At the same time, current transformers 18a-18c and capacitors 19a-19c are provided to interface means 11a-11c. Then a reverse current is produced by the currents flowing through transmitting means 12a-12c and via the transformer a 18a-18c. This reverse current is flowed to the side of the line 3 to prevent the fluctuation of potential for the line 3. At the same time, the current flowing through the common impedance is offset by the reverse current. Thus the fluctuation is avoided for the common potential.

Title: Flow rate measuring apparatus

IPC: G01F1/68
Filed: 1983-06-23
Abstract: PURPOSE:To eliminate two fixed resistances composing a bridge while improving the strength by junctioning a plurality of two kinds of metal filamentous bodies alternately in series on a substrate as thermocouples to arrange the first junction group at the upstream of the electric heater and the second junction group at the downstream thereof. CONSTITUTION:For example, this apparatus is used to measure the flow rate of a sucked air of the engine. A plurality of two kinds of platinum thin film filamentous bodies M1-M100 and N1-N100 are junctioned alternately in series on a flow rate detection substrate 9 as thermocouple. As air flows parallel with the detection surface 9 in the direction of the arrow, the air heated with a heater 17 affects the second junction group 10B downstream but not the first junction group 10A upstream, which causes a temperature difference between both the junction groups 10A and 10B. Drawing the temperature difference direct as an electromovice force signal eliminates the need for drawing the temperature as resistance change to obtain it as power variation through a bridge circuit as in the past.
