摘要： PURPOSE:To quantitatively analyze phosphorus with high accuracy by adding nitric acid and perchloric acid having ultra-high purity to a sample to be analyzed, electrically heating the sample and introducing the evaporated phosphorus into the argon plasma generated by 10-40MHz high-frequency induction heating. CONSTITUTION:An org. material, more particularly bacteria which are the sample to be analyzed are sampled directly into a boat made of a high melting and nitric acid and perchloric acid having the high purity are added thereto. The sample is electrically heated in an inert gas and is thereby decomposed and incinerated; thereafter the sample is heated to 1,500-2,500 deg.C (more preferably 1,700-2,200 deg.C) to be evaporated. The evaporated matter is introduced into the argon plasma generated by 10-40MHz high-frequency induction heating. The phosphorus is quantitatively analyzed from the emission intensity of the excited light. The phosphorus is thereby quantitatively analyzed easily and quickly with the high sensitivity and high accuracy.

摘要： PROBLEM TO BE SOLVED: To provide, in order to make contribution to industrialization of general purpose solder, a method and an apparatus for soldering in which an eutectic alloy mainly composed of tin/zinc can be utilized in the existing facilities to manufacture the tin/zinc solder under the condition that is has been difficult for the tin/zinc system alloy not including lead because zinc is easily oxidized to widely spread the wetted solder to the mother material of soldering object. SOLUTION: IN this method and apparatus for soldering, an alloy consisting of zinc of 3 to 12 wt.% and the remainder substantially composed of tin is placed in contact with a member to be soldered where oxygen concentration in the fused solder is 50 ppm or less and an oxide at the surface of fused solder is eliminated.

摘要： PROBLEM TO BE SOLVED: To make a solder wet well against a substrate by reducing oxygen content in a molten solder alloy which is mainly composed of zinc and tin so as to restrain generation of dross. SOLUTION: A solder alloy mainly composed of zinc and tin is heated to form a molten metal, and the oxygen content in the molten metal is reduced so as to restrain generation of dross. Then, a jointed member, on the surface of which the metal having wettability against the solder alloy is formed, is brought into contact with the surface of the molten metal, so as to form a solder layer on the surface of the metal. Generation of dross depends on the oxygen content in the molten solder, and when the oxygen content exceeds 50 ppm, the dross is surely generated. For reducing the dross, it is effective that oxygen scavenger chosen from, for example, Mn, Al, In, Si, Fe, Ge, P, C, N, B, H, and ammonium is added to the molten metal.

摘要： PROBLEM TO BE SOLVED: To efficiently heat a heating chamber without increase of the cost in a cooker where a heating cooking heater is provided outside the heating chamber. SOLUTION: Grooves 32, 33 are provided in an outer surface of a wall part (upper plate 25 and a bottom plate 26 of an inner box 22) of a heating chamber 23 followed by formation of protruded stripes 34, 35 protruded inwardly of the heating chamber 23, and heaters 34, 35 are formed into a rod shape which is then inserted into the grooves 32, 33 in a closed state. Hereby, the heaters 36, 37 are securely and directly brought into contact with the wall part of the heating chamber 23 increasing a contact area. Further, a back side of the grooves 32, 33 is formed into protruded parts 34, 35, and hereby the wall of the heating chamber 23 is reinforced so that the plate thickness of the wal part of the heating chamber 23 is reduced, and transmission of heat produced by the heaters 36, 37 into the heating chamber 23 is more improved.

摘要： PROBLEM TO BE SOLVED: To decompose a sample and adjust a decomposed soln., without causing contamination with reagents and environment by warming an Si material in a closed vessel to precipitate ammonium salt and volatilizing it away by an oxidative vapor. SOLUTION: A closed vessel 1 has a lid 1a, vessel for supporting a semiconductor substrate and mounting part 2a for mounting the substrate at the center and the vessel 3a and part 2a are filled with HF and HNO3 which are evaporated and absorbed by an Si wafer in the vessel to quickly decompose it. In the HNO3 or HF system, NO3 is reduced by protons into (NH4 )2 SiF6 , precipitating a white ammonium silicofluoride salt having a very strong complex forming power in the soln. This salt is formed with the acid vapor only, and so is a very high purity substance contg. a trace of impurity which is analyzed by the frameless atomic absorption or inductive coupling plasma mass analysis etc.

摘要： PURPOSE:To provide a material for selectively separating anion and method of selectively separating anion so that the objective anion for separation such as fluorine ion can be selectively and efficiently separated and removed from the liquid to be treated. CONSTITUTION:In this material for selectively separating anion, on the surface of a carrier 1 comprising a cation exchanging material, a metal element 2 which selectively makes ion coupling with the objective anion for separation is adsorbed in a charged state. This material for selectively separating anion is brought into contact with the liquid to be treated containing the objective anion 3 for separation and a coexistent material such as other anions 4 so that the objective anion 3 for separation is bonded with the metal element 2 in a charged state. Thus, the objective anion 3 for separation is selectively separated from the liquid to be treated.

摘要： PURPOSE:To make the steady running of a caster body possible even inside a curved pipe by raiseably connecting a pair of the caster bodies provided in parallel so that the phase of a roller supporting shaft rollably supported on the each supporting arm of a body structure at the at least three positions equally divided on the circumference may relatively shift as much as a fixed angle centering around a pivotally supporting point. CONSTITUTION:A body structure l is provided with a hollow shaft 1a to hold a cable 2 at its central part, and plural Y-shaped supporting arms 1b extending radially from the hollow shaft 1a are formed. Hand drum-shaped rollers 3 formed of the partial arc of the same circle as its rolling face are arranged at four equally divided positions on the circumference between the mutually opposite ends of the supporting arms 1b to rotatably bear the supporting arms respectively. The body structure 1 is symmetrically bisected on a line passing through the center of a hollow shaft 1a, and bisected faces are mutually openably connected through a hinge 5 to form a caster body 6. In mounting the cable 2, the divided faces of the bisected body structure 1 are unitedly fixed with screws 7. Thus even when the position of the running face of the cable 2 changes, the rollers 3 of the caster bodies 6 always roll with any of them brought into contact with the running face.
