Title: Analyzing method for rare earth element in glass
Inventor: MIZUSUNA HIROBUMI
IPC: G01N21/73
Filed: 1991-09-20
Abstract: PURPOSE:To analyze rare earth elements incorporated in glass by the induction plasma emission spectral analysis (ICP-AES) method by chemically dissolving the glass by the acid dissolution method, and using the solution. CONSTITUTION:A preset quantity of a glass sample is weighed. It is put into the mixed acid mixed with preset quantities of HF, HNO3 (1+ 1) respectively, and the mixture is heated and acid-dissolved. When H2SO4 (1+1) is included in the solution and Ba, Pb are included in the sample, a preset quantity of HCIO4 is added in place of H2SO4, and it is heated and compressed until white smoke is generated, i.e., white smoke treatment. Hydrogen fluoricle is generated, and the fluoride of the rare earth element becomes a soluble sulfate. This solution is properly diluted, and it is fed to the nebulizer of an ICP-AES device for an emission spectral analysis. The rare earth elements can be detected and analyzed.

Title: Raising seedling culturing pot comprising full-ripe compost formed body and its production
Inventor: TAKASHIMA AKIRA
IPC: A01G9/10
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an environment-corresponding type or labor-saving type raising seedling culture pot capable of entirely planting seedling together with the pot when a molding is prepared by using a natural organic matter and transplanted a seedling therefrom in order to solve inconvenient problems such as waste material produced from already used raising seedling-culturing pot made of plastic, labor of operation, etc., in transplanting. SOLUTION: This pot for culturing raising seedling is produced from natural organic matter of wheat flour containing full-rise compost molding and gluten component. The method for producing the pot comprises adding 25-45 volume % wheat flour to 100 pts.wt. full-ripe compost and kneading these components while adding warm water and forming the kneaded material and drying and baking the kneaded product. Good-quality and uniform full-ripe compost capable of readily forming and solidifying and readily decomposing in sol is desirable as the full-ripe compost which becomes a raw material. For example, a formed body having durability is obtained from a compost produced by mixing feces and urine of livestock such as cow mature with a dried cellulose-containing organic matter such as wheat stem and chaff as a water content controlling material, fermenting and aging the mixture.

Abstract: PROBLEM TO BE SOLVED: To provide an inspecting device for exactly inspecting a differential transformer, even when the fluctuating amounts of the differential output of a differential transformer at the time of impressing an alternating magnetic field for inspection is largely varied for each product. SOLUTION: In a state in which an output voltage at the time of the power supply of a differential transformer 1 is held by a hold circuit 22, the power source of an alternating magnetic field generating circuit 20 for inspection is supplied, so that an alternating magnetic field for inspection can be impressed to the differential transformer 1. When the output voltage of the differential transformer 1 fluctuates to a positive side, the output voltage of the hold circuit 22 is compared with the output voltage of a positive side reference voltage circuit 24 by a positive comparator circuit 26. When the output voltage of the differential transformer 1 fluctuates to a negative side, the output voltage of the hold circuit 22 is compared with the output voltage of a negative side reference voltage circuit 25 by a negative side comparator circuit 27, and quality is discriminated.  Thus, the difference of the differential outputs before and after the alternating magnetic field for inspection is impressed can be detected, regardless of the polarities of the differential outputs so that the quality discrimination of the differential transformer 1 can be conducted exactly, even if the differential outputs are unstable. Also, the alternating magnetic field for inspection is impressed after the power supply of the differential transformer 1, so that the changing amounts of the differential output of the differential transformer 1 can be increased, and the quality discrimination can be conducted exactly.
