摘要： PURPOSE:To enable a plurality of substances to be determined by utilizing a negative value of a result which is obtained by calculation using the energy differential method and by determining the substances. CONSTITUTION:A waist part of a human body is constituted of three substances of bone 11, muscle 12, and fat 13. A transmission information of X rays is measured by a specific measurement system. For example, the measurement system is constituted of an X-rays source, an X-rays line sensor, and an operation device and a two-dimensional measurement can be made by scanning an X-rays line sensor in synchronization with the X-rays source. Then, after measurement, by analyzing a measurement result of the number of count of each part in each energy, it can be identified that fat 23 exists at a negative region after a differential calculation processing. In this manner, not only the bone 11 which is included in a human body but also fat 23 are detected simultaneously for enabling quantitative measurement to be executed.

摘要： PURPOSE:To measure the density distribution of each component with high accuracy by infiltrating a resin or a metal into the gap in the interior of the powder compact of a ceramic or a metal to fix the compact, thereafter exposing the inside of the powder compact, and measuring the concentration distribution of the element at the exposed surface. CONSTITUTION:A powder compact and epoxy resin undergo degassing in vacuum. During this period, the powder compact is heated to about 200 deg.C in order to evaporate the adsorbed material in the surface of power. Then, the powder compact is cooled, and the powder compact and the epoxy resin are brought into contact. The atmosphere is returned into the atmospheric pressure, and the epoxy resin is infiltrated into the inside of the powder compact. After the epoxy resin is solidified, the powder compact is polished. The epoxy resin is brought into contact with a part of the exposed cross section, wherein the epoxy resin is not infiltrated, in the vaccum state. Pressure is applied, and the pressure is maintained until the resin is solidified. After the resin is solidified, the surface to be evaluated is finished as the mirror surface and exposed. The intensity of the characteristic X rays of uranium element at the exposed surface is measured by an energy dispersion type X-ray analyzer, and the relative density is obtained.

摘要： PURPOSE:To quickly and precisely analyze impurities contained in minute amount in a specimen for measurement of Bi oxide, when it undergoes a press process, by adding a specific amount of binder to the Bi oxide, and performing the press process under specific conditions. CONSTITUTION:A binder in an amount 2-10wt.% of the weight of Bi oxide is added thereto to perform a press process to prepare a specimen for measurement of Bi oxide under the conditions that the press pressure ranges 2-10ton and the press duration ranges 10-30sec. To make analysis, first a standard specimen for calibration curve is prepared by sampling a certain amount of Bi oxide as the object to be analyzed, to which such impurities as aluminum, Pb, Ni, etc., are added in the form of standard solution having a prefixed composition. They are crushed, kneaded, and pressure molded, in which paraffin may optimally be used as the binder powder. The X-ray intensity in this molding of standard specimen is measured, and the calibration curve is prepared. Alike the X-ray intensity in the specimen for measurement is determined, and the concentration of the impurities is quantified from the relationship between this determined intensity value and the calibration curve.

摘要： PURPOSE:To enable accurate determination of particle concentration in a liquid sample with unknown particle concentration by measuring the particles in liquid or gas in the region where beam waist volume and acoustic wave generation rate are in linear relation. CONSTITUTION:A sample liquid is sent to a cell 10. Optical system components such as the transmittance of a polarization filter 12, laser beam diameter and beam waist position, etc., are automatically adjusted so that the beam waist volume is set at maximum. Then, a laser beam is directed from a YAG pulse laser 11 to the cell 10, adjusted automatically similarly to the initial adjustment and the beam waist volume is calculated 33. After setting the beam waist volume to a value close to the initial set value, the particles are measured 28. By repeating this measurement, the relation between the beam waist volume and acoustic wave generation rate is examined 30 based on the result, and the existence of a linear relation is investigated 31. If they are not in linear relation, the beam waist volume is reset to a value smaller than the set value measured immediately before and the existence of linear relation for the set value is reinvestigated. If they are in linear relation, the volume setting is terminated and the continuous measurement of particles is performed.

摘要： PURPOSE:To design the enough security of a visual field and the prolongation of a maintenance cycle by preventing the cohesion and the accumulation of dust making a mirror downward when a lifter goes down and an image sensor has not detected the rotation of a package. CONSTITUTION:A link coupled with a rotatable mirror 7 is rotatably installed in a lifter 2 installed with an image sensor 4 and the mirror 7, and a pair of weights with a weight difference between both coupled with a wire rope 17 are held through pulleys 16a, 16b. The middle part of the wire rope 17 is connected to the link 9. Further, the rise of the lighter weight 14 due to the weight difference is bound by primary stoppers 20a, 20b when the lifter 2 goes down and by a secondary stopper 21 in the rising course of the lifter 2. By this, the link 9 rotates to the other side and the mirror 7 is rotated to the same direction because the weight 14 pulls the weight 13, and the wire rope 17 is run and moved to the weight 14 side.

摘要： PURPOSE:To measure density and the amount of moisture highly efficiently and stably by using a phoswich-type detector which is constructed by combining an NaI scintillator and a plastic scintillator optically with one photomultiplier tube. CONSTITUTION:A gamma-ray and a fast neutron-ray radiated from a radiation source 1 are transmitted through a substance 20 to be measured and are detected by a plastic scintillator 15, while the gamma-ray is detected also by an NaI scintillator 4. A pulse- shape discriminating circuit 16 separates a detection signal by the scintillator 15 from a detection signal by the scintillator 4 by utilizing a difference in a pulse rise time between the two signals. Next, the counting rate Np per unit time of the separated detection signal from the scintillator 15 and the counting rate Nc of the detection signal from the scintillator 4 are counted. Then, CPU 19 distributes the counting rate Np to a gamme-ray contribution part Ngamma and a fast neutron-ray contribution part Nn on the basis of a distribution ratio determined by the construction of a phoswich-type detector 3 and the radiation source 1m and calculates the amount of moisture of the substance 20 to be measured on the basis of the counting rate Nn of the fast neutron-ray and the density on the basis of the counting rate Ngamma of the gamma-ray.
