Title: Sample diluting method
Inventor: OOYABU MATASHIGE
IPC: G01N1/14
Filed: 1987-05-25
Abstract: PURPOSE:To improve analyzing accuracy, by discharging a specified amount of a sample so that the attaching amount on a container wall is suppressed to the minimum value, discharging a specified amount of diluting liquid at a high speed from a place higher than the sample discharging position, and diluting and regulating the sample to a specified concentration. CONSTITUTION:A path from a pure water well 7 to a nozzle 22 is filled with pure water by a switching driving of a diluter driving part 42 and a three-way solenoid valve 6. Then a specified amount of a sample is sucked through the nozzle 22 from a sample container on a sample line 31 on a turntable 3. Then, a sampler arm 21 is turned, and the nozzle 22 is set over a specified diluting container on a diluting line 32 on the table 3. Thereafter, a rack pinion 26 is driven. The tip of the nozzle 22 is stopped at a position in the vicinity of the bottom of the diluting container. The sucked sample is quietly discharged. When the discharge of the sample is finished, the pinion 26 is driven, and the nozzle is lifted. a specified amount of pure water is discharged at a high speed from a position higher than the position at the time of the sample discharge under this state. Since the sample is diluted into a specified concentration by the force of the discharging of pure water, the accuracy of analysis is improved.

Abstract: PURPOSE:To simplify the structure in comparison with the former angular casing in such a way that the sectional shape of a casing of a trough conveyor to convey flour, etc. is formed circularly or elliptically. CONSTITUTION:When a shaft 4 is driven by a geared motor, a chain 16 is turned in the direction as shown by arrows, objects to be conveyed which have been gradually thrown from an inlet port 19 are portioned out through a return housing 6 to the left and right coming into a feeding housing (a) through which the inlet port 19 is penetrated, the objects to be conveyed are conveyed through an attachment of a chain 16 which runs through the bottom part into a head part housing c, and further discharged through a discharge port 10. Since the housings (a), b are circularly or elleptically shaped in their sectional form, when manufacturing, it is enough only to cut the existing pipe material to the desired length, and to provide flanges for connecting them, and since the object to be conveyed runs of its own accord to the bottom part, there is not partial stangnancy.

Abstract: PROBLEM TO BE SOLVED: To solve such a problem that uniformization of the carbon concn. in a silicon single crystal ingot in the direction of its crystal growth axis is difficult by any conventional production, and to produce a silicon single crystal having a constant carbon concn. in the single crystal ingot and good crystal properties, at the time of producing a silicon single crystal in which the generation of oxygen precipitate is promoted by carbon doping, with a CZ(Czochralski) method. SOLUTION: In this production, at the time of performing a single crystal pulling-up operation in an atmosphere of a gaseous mixture obtained by mixing a gas contg. carbon and/or a carbon compound, either alone or together with another gas contg. carbon and/or a carbon compound, or the like, with an inert gas such as Ar, influence of the segregation coefficient of carbon at the time of growing a single crystal is remarkably mitigated and the carbon concn. distribution is almost uniform even in the diameter direction of a single crystal ingot thus produced.  Accordingly, the carbon concn. within a produced single crystal ingot can be adjusted to a constant value by changing the amount of a gas to be introduced at the time of growing a single crystal by pulling-up, based on the carbon concn. gradient within a produced similar single crystal ingot, measured after growing a similar single crystal by pulling-up while introducing a carbon-doping gas at a constant flow rate, in a previous run.

IPC: H05B33/10
Filed: 1989-05-22
Abstract: PURPOSE:To enhance luminance of a thin film electroluminescence element by subjecting a base to a heat treatment in the presence of an oxidizing gas after a light emitting layer is formed and before a conductive film is formed on the base. CONSTITUTION:A base is subjected to a heat treatment at least once in the presence of an oxidizing gas after a light emitting layer is formed and before a back electrode is formed. As the oxidizing gas, nitrogen oxide such as N2O and the like, carbon oxide such as CO2 and the like, sulfur oxide such as SO2 and the like are used, or inactive gases such as Ar, N2 and the like may be used after dilution. In an atmosphere containing oxidizing gas, the partial pressure of the oxidizing gas is more than 0.1 Pa. The heat treatment is carried out at temperatures in the range of 200 to 650 deg.C. Oxygen is thereby introduced into the light emitting layer to compensate for the defect of IVB group elements in the light emitting layer, thereby enhancing luminance of the thin film electroluminescence element.

Abstract: PURPOSE:To obtain focusing with high accuracy, by branching an optical path passing an objective system, observing an object to be examined with the one thereof, branching further the other optical system and providing a light projecting means in the one t hereof and a photodetecting means in the other. CONSTITUTION:When a semiconductor laser 17 is oscillated, laser light is converged with a lens 18 and the converged light illuminates a mask 19. The luminous flux past the area on the outside of the mask 19 passes a semitransparent mirror 20 and is reflected by an optical branching filter 13, from which the luminous flux is made incident through an objective lens 12 to an object 11 to be examined. This flux is reflected by said object, is passed through the lens 12 and is further reflected by optical branching filters 13, 20. The image thereof is formed with a lens 21, and is made incident via a filter 22 to a photodetector 23. If the object surface 11 and the photodetector are conjugate with each other, the light distribution on the photodetector 23 is such that the position of the optical axis peaks. However, in the case of a front focus or rear focus, the one side of the projected light is vignetted by the mask 19; therefore, the photodetector 23 is driven to scan the light distribution and the scanning is continued until the peak of the light distribution coincides with the boundary of the regions 23, 24.
