Title: A/d conversion circuit
Inventor: SHINOZAKI SATORU
IPC: H03M1/36
Filed: 1989-09-05
Abstract: PURPOSE:To improve the accuracy of linearity by arranging reference resistance element arrays setting a reference voltage of each level of an analog input signal in parallel and cancelling a slight difference of the resistance of the parallel resistors. CONSTITUTION:An array of reference resistors 2A-2H equivalent to right reference resistors 1A-1H connected in series is arranged in parallel, a fixed voltage caused between a positive reference voltage input terminal 4 and a negative reference voltage input terminal 3 is applied opposite to the arrangement of the layout of the resistor arrays, connecting points of resistive elements of equi-potential of each resistive element array, that is, resistors 1A and 2A, and resistors 1B and 2B are connected in parallel. When the resistance of the reference resistive elements is changed gradually from the upper to the lower direction shown in figure, the resistance of the resistive elements in the adjacent parallel resistive element array is similarly changed gradually, and even when the relative error changes slightly, the error in the change such as the error in the reference voltages by the resistors 1A, 2A is compensated. Thus, the DC linearity is improved.

Abstract: PURPOSE:To improve the accuracy of microanalysis by constructing a titled cuvette in such a manner that the electrode of an atomic absorption spectrophotometer contacts a graphite base material and the inside peripheral film of thermally decomposed carbon and does not contact the outside peripheral film of the thermally decomposed carbon. CONSTITUTION:The pyrocuvette formed by coating the thermally decomposed carbon on the surface of the cylindrical graphite base material 8 is so constructed that the electrode 1 of the atomic absorption spectrophotometer contacts the base material 8 and the inside peripheral film 7 of the thermally decomposed carbon and does not contact the outside peripheral film 6 of the thermally decomposed carbon. A coke-series artificial graphite material which is worked to a cuvette shape is preferable for the base material 8. The film 7 or end face film 10 is formed by vapor deposition to a laminar shape of which the section is contacted with the electrode 1 to permit the flow of electric current to the film 7. The film 7 formed to >=30mum thickness is preferable as the current is easier to flow to the film 7. The part of the film 6 near the electrode 1 is removed by machining, etc., so as not to contact the electrode 1. The accuracy of the microanalysis is thus improved.
