Title: Converting device of mechanical displacement for aircraft
Inventor: UDAGAWA TOMOYUKI
IPC: G01D5/20
Filed: 1979-10-15
Abstract: PURPOSE: To keep fixed the absolute value and phase of an exciting current constantly by using a constant-current circuit as a power circuit exciting the primary winding of the converting device.  
     CONSTITUTION: In between a constant-voltage source V and the primary winding P of a converter PC is inserted the constant-current circuit CI consisting of a differential amplifier A1 such as an operational amplifier and a resistor R1 feeding back the current as the power circuit, whereby the terminal voltage of the resistor R1 generated by the current flowing to the primary winding P is negatively fed back to the inversion input of the differential amplifier A1 and thus the current flowing to the primary winding P is kept constantly fixed. By this, a large-sized and heavy choke coil becomes unnecessary and the absolute value and phase of the electrical output are turned to be stable and can be kept fixed.

Title: Method and apparatus for spectrochemical analysis utilizing atomic light emission
Inventor: KAJIWARA HISAO
IPC: G01N1/00
Filed: 1984-06-26
Abstract: PURPOSE:To remove interference component elements in a sample, by guiding the sample to the inside of a cation exchange film tube, whose outside is filled with a specified removing liquid, and exchanging the ion exchanging group in the tube by the cation in the sample. CONSTITUTION:When a pump 4 is driven, a sample in a bath 1 passes cation exchange film tubes 2 and 2' and flows out of a capillary 6 of an outlet part 5. A spectrochemical analysis apparatus utilizing atomic light emission is provided in this way. When the sample passes the cation exchange film tube 2' in a bath 3, the sample is contacted with a removing liquid in the bath 3. The ion exchange group in the cation exchange film 2' is exchanged by the cation in the sample. Even if interference component elements are present in the sample, the elements are removed and are not included in the liquid, which flows out of the capillary 6. Therefore, even if the interference component elements are included in the sample, the element to be measured can be accurately measured.
