Title: Method and apparatus for analysis of slug
Inventor: YAMAMOTO AKIRA
IPC: G01N21/71
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which an instruction based on an analyzed value can be given precisely and quickly to a refining operation by a method wherein the bonding species of an element contained in a slug is identified on the basis of a wavelength at which the intensity of the directly collected infrared emission spectrum of the slug displays a peak and its concentration is quantitatively determined. SOLUTION: In this method, infrared rays are collected directly from a slug inside a refining container by using a collecting and condensing system 5 which is installed at the upper part of the refining container. That is to say, an optical fiber 1 is cooled by a water-cooled jacket 2, and a condensing optical system 4 which is composed of a convex lens and a concave lens collects the infrared rays from the wide range of the slug. At this time, dust particles which disturb a measurement are removed as an inert gas 13 from an atmosphere up to the surface of the slug to be light-collected by using a gas blowoff port 12, and a part of the inert gas 13 is blown to the surface of the lens so as to prevent the dust particles from being stuck.  A spectral device to which the collected infrared rays are conveyed from the optical fiber 1 measures the intensity of every infrared spectrum of the bonding species of an element contained in the slug, and the bonding species of the element is identified on the basis of the peak wavelength of the intensity of the spectrum. The intensity of the spectrum is compared with a working curve, and the concentration of the bonding species is quantitatively determined.

Title: Production of compound semiconductor single crystal
Inventor: SATO TAKAYUKI
IPC: C30B15/00
Filed: 1991-12-05
Abstract: PURPOSE:To efficiently obtain a uniform large-sized crystal low in dislocation density by starting the growth of crystal and changing the atmosphere pressure stepwise to obtain the desired crystal barrel diameter. CONSTITUTION:The growth of crystal is started by the liq. encapsulating Czochralski method under the atmosphere pressure P1 higher than the dissociation pressure P0. The atmosphere pressure is then kept at the constant pressure P1 until achieving the length L2 which is greater than L1 where the shoulder formation of the crystal has been completed. The average pressure changing rate is then controlled to <=1kg/cm<2>.min, the pressure P1 is lowered to P2, and the pressure control is stopped at L3. Meanwhile, after the barrel diameter is stabilized at L2 which must be as close to the substrate as possible, the compd. semiconductor single crystal is produced while maintaining the pressure P2.

Filed: 1989-12-14
Abstract: PURPOSE:To improve the wear resistance of the material in a high temp. range by impregnating an Mo-Si-Ni series material constituted of an intermetallic compound into the pores of an iron-base sintered material. CONSTITUTION:An Mo-Si-Ni series material substantially consisting of an intermetallic compound Mo(Si,Ni)2 is impregnated into the pores of an iron-base sintered material having 5 to 25vol.% porosity to form a wear-resistant material such as a valve seat. Because the Mo(Ni,Si)2 intermetallic compound has a relatively low m.p., its infiltration can sufficiently be executed, and since the above m.p. is equal to or above the using temp. of the iron-base sintered material, elution does not occur, so that the intermetallic compound has hardness equal to that of hard grains. In particular, resistance to abrasive wear can be increased.

IPC: G03G15/01
Filed: 1989-12-12
Abstract: PURPOSE:To always accurately detect the density of a developed image by holding a sensor on a transfer material carrier so that a detection optical path may be held between the surface of an image carrier and the transfer material carrier and detecting the density of a toner image on the image carrier opposed to the sensor on the detection optical path. CONSTITUTION:The sensors 100 and 101 which optically detect the density of the toner image are held and provided on the transfer material carrier 36 so that the detection optical path 50 may be held between the surface of the image carrier 1 and the carrier 36. At the time of detecting the density of the image, a reference pattern is exposed and developed at a specified position on the image carrier 1. Since a transfer sheet is not fed in such a case, the developed images of the reference pattern are opposed some time on the sensors 100 and 101 and the detection optical path 50 by the rotation of the image carrier 1 and the transfer material carrier 36. At such a time, the transfer sheet does not shield the detection optical path 50 and the surface of the transfer material carrier 36 is cleaned at a proper time, so that the detection optical path 50 does not receive the effect of contamination. Thus, the density of the developed image is accurately detected.

Filed: 1988-12-21
Abstract: PURPOSE:To make it possible to separate the regulation of a reaction solution from the measurement of a reaction speed by providing a refrigeration chamber for keeping a plurality of reaction solutions already regulated, a heating chamber for heating the solutions to a solution temperature suited for analysis and a means of having the reaction solutions sucked into measuring cells. CONSTITUTION:A sample is injected separately in reaction vessels S, a prescribed quantity of reagent is added thereto and then all the vessels S are accommodated in a refrigeration chamber 3. Next, a belt conveyor 7 is operated and the vessels S in the refrigeration chamber 3 are moved thereby to a heating chamber 4. A reaction solution in each vessel S is thereby heated. At the time point when the reaction solution is heated near to a measurement start temperature, the vessel S is taken out of the heating chamber 4 and the reaction solution is sucked into a flow cell 13 of an absorbance measuring element 10. Since the reaction solution is kept in the refrigeration chamber 3 whose temperature is lower than a room temperature, in this constitution, reaction of a target substance with the reagent proceeds little, and since a time required for the rise in temperature is the heating chamber 4 is short, in addition, the reaction proceeds in the same process as when the reagent is added initially. By measuring the speed of a change in the absorbance in this stage, accordingly, the concentration of the target substance in the sample can be measured accurately.
