Title: Quantitative analysis of copper peroxide (cu3+) in oxide superconductor
Inventor: HAYASHI MASARU
IPC: G01N31/00
Filed: 1987-07-29
Abstract: PURPOSE:To easily and rapidly determine copper peroxide (Cu<3+>) by decomposing a sample to be analyzed with an inorg. acid added with an Fe<2+> ion soln. and titrating the unreacted Fe<2+> ions in the resultant sample soln. with a standard oxidation soln. CONSTITUTION:Gaseous N2 is fed from an inert gas supplying device 3 into a analyzing vessel 1 to replace the air with the gaseous N2. This supply is continued until the titration ends. A prescribed amt. of the ground analysis sample is then weighed into the vessel 1. The standard Fe<2+> ion liquid and the inorg. acid are then added thereto and the soln. is heated to at least >=30 deg.C on a hot plate 2 which is a heat source to decompose the oxide superconductor. Then, part of the instantaneously dissolved Cu<3+> ions react with the Fe<2+> ions to form Cu<2+>. The unreacted Fe<2+> ion remaining in the resultant sample soln. are thereafter titrated with the standard oxidizing liquid, by which the copper peroxide (Cu<3+>) in the oxide superconductor is determined.

Abstract: PURPOSE: To form a laminated sheet having improved water absorption and good punchability and impact resistance, by combining two kinds of substrates, each subjected to a special pretreatment, as substrates to be impregnated with an unsaturated resin.  
     CONSTITUTION: (A) Substrates (e.g., kraft paper) are pretreated with a treating resin (e.g., melamine resin or phenol resin) and an epoxy resin to infiltrate the resins into the substrates and then the substrates are impregnated with an unsaturated resin solution (e.g., liquid composition, viscosity 500W4,000 P, consisting of an unsaturated polyester, a crosslinking agent, a thermal polymerization initiator, etc.). Similarly, (B) substrates pretreated with the treating resin only are impregnated with the unsaturated resin solution. Then, the sabove-produced substrates are laid so that the substrates obtained in (B) form both of the external layers and at least one substrate obtained in (A) forms an internal layer, and the resulting assemblage is contact-molded under heating to form a laminate sheet.

Title: Measuring device for temperature of coke oven
Inventor: BIZEN YOSHIHIRO
IPC: G01J5/00
Filed: 1981-11-26
Abstract: PURPOSE:To accurately measure temperature, by a method wherein a memory operating circuit, storing a larger output after an output from a thermometer is compared in order, is installed, and a data, stored in the circuit, is converted into temperature. CONSTITUTION:After an output signal measured by a thermometer 2 is amplified it is sampled at intervals of a given time based on a signal from a sampling signal generator A and is A/D-converted. It is then stored as a digital volume in a memory operating circuit C, and only a larger data is left after comparison of the sizes of the data with each other. This causes leaving of a maximum value of a single flue nozzle. The largest value is transmitted as the temperature data of the nozzle to a control room D. This enables the maximum value against the flue nozzle to be measured, to be found in order, whereby based on the value, temperature of each combustion chamber is found, the temperature of each combustion chamber is displayed by processing the data, and simultaneously, the combustion condition of each combustion chamber is controlled.

Title: Corrosion resisting material for hydroelectric power plant, and hydroelectric power plant using the material
Inventor: KANAZAWA YUKIO
IPC: C22C38/22
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain a corrosion resisting material having sufficient corrosion resistance even in highly corrosive water by incorporating a specific composition of Cr, Mo, and the balance essentially Fe. SOLUTION: The corrosion resisting material is composed of a cast stainless steel having a composition consisting of, by weight, 12.5-17% Cr, 0.5-4% Mo, and the balance Fe with inevitable impurities. Owing to this composition, the corrosion resistance of the material in highly electrically conductive water, such as seawater, acidic river water, and river water of >=100 gS/cm<2> electric conductivity, can be improved. Cr is an important element to improve the corrosion resistance of the material itself in the above conductive fluids. However, the corrosion resistance of the alloy is sharply reduced when its content is above the upper limit value as well as below the lower limit value.  Mo is an element which contributes to the improvement of pitting corrosion resistance in conductive water by the coexistence with Cr, but a problem of embrittlement of the material is brought about when its additive quantity exceeds the upper limit value.

Filed: 1986-08-13
Abstract: PURPOSE:To enable printing to be executed even in the case where a character which can not be printed in one line is mixed, by a method wherein by judging whether a character information having the size concerning a plurality of lines exists in the line of an indicated document memory or not, a printing start line is determined and at the same time, the feed quantity of form is determined according to the judged result. CONSTITUTION:After indicating the line required to be printed by the cursor key or the like of a key board, the control program of one line printing is started by pushing down a one line printing indication key. For judgement of a character information, when a carrier returns to the original position (STPC=0) by the reverse rotation of a carrier motor 18, whether a flag FLG is turned on or not is observed. When the flag FLG is turned off, i.e. when any four times magnified character does not exist in a printed line, a form is fed by a line pitch content. On the other hand, when the flag FLG is turned on, the form is fed by 16 dot content corresponding to the dot number of a thermal head. Even if any magnified character exists in the case where printing is effected while preparing a sentence line by line, the magnified character can be made out without being interrupted midway.

Title: Electronic apparatus for internal-combustion engine
Inventor: YOSHIDA TATSUYA
IPC: F02D41/26
Filed: 1983-10-12
Abstract: PURPOSE:To prevent a control circuit from coming into a runaway state without fail, by installing an logical circuit taking ''AND'' of a low voltage detection reset circuit, a power-on reset circuit and an output of the low voltage detection reset circuit. CONSTITUTION:In a power-on reset circuit 13, its output signal temporarily becomes a low level when a power source is switched on. A watchdog timer 14 outputs a reset signal when a pulse is not inputted within a fixed period of time from a control circuit 17. A low voltage detection reset circuit 100 takes in voltage of a battery 1 and outputs the reset signal when the battery voltage becomes less than the specified value. When any signal of these reset circuits 13, 100 and the timer 14 becomes a low level, output of an AND circuit 15 also comes to the low level. Thus, even if the battery voltage temporarily drops, the control circuit can be reset securely.
