摘要： PURPOSE:To provide a determination method for glow discharge spectrochemical analysis excellent in the quantitative properties of bulk concentration of an alloy and the distribution thereof in the depth direction from the surface of the alloy. CONSTITUTION:Sputtering rate, emission intensity, discharge voltage and discharge current of a standard sample are measured under constant current mode or constant voltage mode. Bulk concentration of an allay or the concentration of the alloy in the depth direction from the surface is then determined based on the relationship between the emission intensity obtained from a sample to be measured and the sputtering time using an effective emission yield calculated based on the measurements.

摘要： PURPOSE:To enable analysis by obtaining two opposed fractured sections forming a grain boundary in a clean state, by feeding out two specimen pieces on a specimen holder to the outside of a container along with the specimen holder by a specimen feeding fork. CONSTITUTION:A specimen 14 is mounted between an upper specimen receiving stand 5 and a lower specimen receiving stand 6. A hydraulic cylinder 11 is controlled to fall the lower specimen receiving stand 6 and load is preliminarily detected by a load cell 10 and the cylinder 11 is stopped immediately before load is applied to the specimen 14. The hydraulic cylinder 11 is set to a predetermined strain speed to start a test and the specimen 14 is broken. After breaking, an upper side specimen holder 15 is detached by a specimen feeding fork 16 and the specimen 14 is delivered to a vacuum carrier fork 17 at a specimen delivery position. A lower side specimen holder 18 is raised to the specimen replacing position on the upper surface of a test stand 1 by controlling the hydraulic cylinder 11. The lower side specimen holder 18 is detached in the same way as the upper side specimen holder 15 by the specimen feed fork 16 to deliver the specimen to a vacuum carrier fork 17.

摘要： PURPOSE:To measure the composition and the thickness of a surface layer, by measuring the depth profile of the surface of a solid by spectrochemical analysis using glow discharge, converting the sputtering time into the thickness by matrix effect correction, and converting light emitting intensity into element concentration. CONSTITUTION:The depth profile of the surface of a solid, which is expressed by the sputtering time and the light emitting intensity of an element, is measured by spectrochemical analysis using glow discharge. The depth profile is divided at every unit time. The light emitting intensity of each element is converted into the concentration of each element by correcting the mutual interference effects of coexisting elements, and the composition is determind. Then, based on the determined composition, the sputtering speed is corrected, and the thickness at every unit time is determined. Based on the obtained composition and the thickness, the sputtering weight at the part of the unit time is determined. Thus the element concentration, thickness and weight of the surface layer of the solid are determined.

摘要： PURPOSE:To improve the uniqueness in corresponding relation between a magnetic field value and coil current by hunting the coil current near the objective magnetic field value and bringing the coil current close to the objective magnetic field value while the amplitude of the hunting is diminished gradually. CONSTITUTION:Secondary ions generated from a sample 1 are accelerated with an acceleration electrode 2, detected with an ion detector 10 through an electric field 3 and a magnetic field 4, and the results are output on an output device 12 through an arithmetic unit 11. On the other hand, all mass numbers required to analyse are obtained by calculation or measurement, and are previously memorised in a memory 13. When, the magnetic field 4, a magnetic field detecting element 5, magnetic field detecting circuit 6, magnetic field controller 8, and magnetic field generating circuit 9 form a feedback loop which is to obtain the magnetic field intensity corresponding to output of a magnetic field setting devive 7, a coil current is hunted near the objective magnetic field value by its dynamic characteristics, and the coil current is brought rapidly close to the objective magnetic field value while the amplitude of hunting is being gradually diminished.

摘要： PURPOSE:To compensate accurately the magnetic field intensity for peak center by introducing compensating quantity given as a function of the mass number. CONSTITUTION:A secondary ion generated in a sample 1 is accelerated with an accelerating electorde 2, and detected with an ion detector 10 through an electric field 3 and a magnetic field 4. Outputs of a magnetic field detecting circuit 6 and magnetic field value setting device 7 are compared with a magnetic field controller 8 comprising a comparator, and a magnetic field generating circuit 9 controls an exciting current to obtain magnetic fields of each step corresponding to the output. Because the magnetic field is controlled directly by signals which represent the magnetic field, a mechanism for conversion of magnetic field intensity to mass number is needless. An arithmetic processing unit 13 figures out a peak center magnetic field corresponding to the mass number referring to contents of a memory 17 when the mass number is input from an input unit 18 to the memory 16.

After that, an overhanging section 41 is fixed for the formation of a side-span girder 13. While a center-span girder 15 is assembled on a side-span girder 13a, a bridge pier 17 and an abutment 19 are constructed on the footing 7 below the girder 13, and the girder 13 is erected by being jacked down on the bridge pier 17 and the abutment 19. Concurrently with the assembly and erection of the girder, T-shaped precast retaining walls 43 are installed in two rows in the planned position of the bank 23, so that a base section 71 can be formed and so that a backfill 61 can be installed. An L-shaped precast retaining wall 65 is installed to form a side section 73, and back-filling is performed by means of a backfill 67 so that the bank 23 can be constructed.
