摘要： PROBLEM TO BE SOLVED: To suppress the vibration of a sensor for diagnosis, reduce the friction between an image transmission cord and the wall in a pipe, and to achieve a stable and accurate diagnosis, by sending a diagnosing device into the pipeline by means of an intermittent fluid or a spiral flow fluid. SOLUTION: A compressed air is supplied to an inlet unit 3 via an annular Coanda slit 4, thus generating a Coanda spiral flow. An image transmission code 7 and an image sensor 5 for diagnosis at the tip are inserted into a pipeline while vibration and friction with the inner wall of the pipeline are small due to the Coanda spiral flow fluid flow generated in a flexible hose 2 and the pipeline 1, thus diagnosing the pipeline at a required position. An inclination surface 9 where a diameter is reduced toward a connection part 8 is formed near a Coanda slit 4 of the inlet unit 3. A spiral flow is formed by the inclination surface 9 and an image transmission cord 7 is guided by a negative pressure suction force generated at an introduction port 6.

摘要： PROBLEM TO BE SOLVED: To avoid a work-flaw and distortion by cutting with a high speed rotary cutting edge while jetting water for working a place other than observed with an electron microscope, and polishing with a side surface of the high speed rotary cutting edge while jetting polishing liquid when a place including the sample place is worked. SOLUTION: A rotary cutting edge 1 is rotated fast with an air spindle motor 1-1, and a cut sample 2 is held on a sample bed 2-1 which is set on a working position. Polishing liquid 3 flows through a circulation system such as a polishing liquid tank 4, a supply pump 5, a supply pipe 6, a nozzle 7 and a discharge pipe 9, etc., and it is automatically switched to water, which is supplied from a supply system pipe 12 through an control valve 12-1, with a supply system three way cock 13. When a place other than observed with an electron microscope, of the cut sample 2 is worked, cutting work is performed with the fast rotary cutting edge 1 while jetting water. Meanwhile, when a place which contains the to-be-observed part is worked, non-contact polishing is performed with a side surface of the fast rotary cutting edge 1 while jetting polishing liquid. By this method, the to-be-observed part of the cut sample 2 which has no work-flaw or residual distortion is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a stable plasma flow with little turbulence which is converged to the blowout axis by making a current flow to a high frequency coil, and making a spiral flow passing a gradually contracted tube part into a plasma. SOLUTION: An inert gas is supplied from a gas feed port 6, and the gas is blown out through an annular Coanda slit part 3. The angle θ of an inclined surface 3 is set to 5-70 deg., whereby a Coanda spiral flow which is one kind of turning flows is formed in the process of passing in a gradually contracted tube part 7 to develop a strong negative pressure sucking force in a suction port 2, and the spiral flow is consequently sucked into a device through the suction port 2 by the negative pressure sucking force. Further, the current is made to flow to a high frequency coil 8 wound on the outer wall of the gradually contracted tube part 7 to make the spiral flow passing the gradually contracted tube part 7 into a plasma. Thus, the plasma flow containing this turning spectrum component is converted to the blowout axis, and further forms a stable plasma flow with little turbulence.

摘要： PURPOSE: To improve the efficiency of removing operation at the time of accumulating and condensing the product at a specified position by accumulating and condensing more product CONSTITUTION: Since a drainpipe Pa is clamped by the inclined faces of the tip faces of treating devices A, a magnetic field is inclined, the magnetic field at the place of the tip face abutting on the drainpipe Pa is the strongest, hence more product is accumulated and condensed in the drainpipe Pa at the abutting part, and the product is gradually sucked and moved toward a discharge port Pb where the magnetic field is weak.

摘要： PURPOSE:To enable very small amounts of impurities to be detected in materials with high purity by installing a vacuum evaporation source inside a sample chamber vacuum tank, coating the contaminated surface of the constituents of a device by means of metallic thin films so as to reduce the effect on memory due to contaminated layer and/or influence of contamination caused by remaining gases. CONSTITUTION:Prior to the spectroanalysis of a sample 6, a material stage 7 is moved from the position of a analysis to give no hindrance to the process of vacuum evaporation, for the purpose of coating a contaminated layer on the surface of a lead-out electrode 9 etc., with a metallic thin film. Then, a vacuum evaporation source 15 is actuated, to generate metallic vapor 16 which is guided to adhere to the lead-out electrode 9 or the surface of a cover in a primary ion optical system to form a vacuum evaporated metallic thin film. Owing to the abovementioned constitution, a memory effect or contamination by remaining gas used to hinder a microanalysis can be alleviated to enable very small amounts of impurities to be detected in materials with high purity.

摘要： PURPOSE:To increase a sensitivity by irradiating compound ions containing an oxygen ion or oxygen from an ion source different from a primary ion source and conducting an analysis with an oxygen density of 30atom.% or above in an analyzing region from the surface of a specimen to an about 2,000Angstrom depth. CONSTITUTION:An ion implantation optical system 2 for sputtering a specimen in an analysis is provided together with a primary ion optical system 1 composed of, for example, an ion source 4 and the like and an analytic result is displayed on a CRT 16 or the like via a secondary ion optical system 3. The optical system 2 is constructed so that accelerating energy can be set to 1-1,000kV. Accelerated ions are irradiated from an implanting ion source 10 on the surface of a specimen 9 to increase an oxygen density on a measuring surface and increase the yield of secondary ions of impurities in the specimen. Accordingly, the highly sensitive analysis can be conducted.
