摘要： PURPOSE:To provide a high speed injection type burner which has absorption against thermal expansion and contraction, excellent shielding ability, and excellent durability. CONSTITUTION:Air pipes 3 are concentrically disposed at specified intervals to the outer periphery of a gas pipe 1, and burner cases 4 are concentrically arranged at specified spaces on the outermost periphery. The outer peripheral surface of the rear end part of the gas pipe has a structure in which combustion gas is sealed by a packing material 10 embedded in the forward end of a seal nut 11. A ceramic air nozzle 6 is coupled with a connection at the forward end of an air pipe 3, a part of the outer periphery of the forward end of the air nozzle engages with an engaging groove 16 formed in a mixture nozzle 6, and the end face of the air nozzle 6 is brought into contact therewith with a distance which is enough to absorb the expansion and contraction of a burner. The rear end part of an air burner nozzle pipe 3 is provided with a positioning set nut 7, and the rear end face of the burner case 4 is secured in a manner to hold it between the nip formed by a fixed nut 8 and the set nut. Further, the outer peripheral surface of the rearmost end part of the air pipe 3 is forcibly adhered by means of a fixed bolt 12 mounted to the fixed nut 8.

摘要： PURPOSE:To obtain lanthanum chromite having a small particle diameter and uniform compsn. CONSTITUTION:The lanthanum chromite is produced by pyrolysis of La[Cr(CH2(COO)2)3].xH2O at >=750 deg.C. La[Cr(CH2(COO)2)3].xH2O is prepared by the reaction of potassium salt of chlomic acid with malonic acid to obtain a complex and then effecting ion exchange of potassium in the complex with lanthanum. Thereby, lanthanum chromite having 0.4-0.5mum grain diameter and fine and uniform compsn. is obtd.

摘要： PURPOSE:To contrive an increase in the temperature coefficient of resistance of a positive characteristic thermistor and the rate of change of resistance of the thermistor without changing the basic electrical characteristics of the thermistor by a method wherein a small amount of tin or selenium is added to the temporarily sintered powder of a composition consisting of barium titanate obtainable by replacing one part of barium with strontium and after they are mixed, the mixture is molded and sintered. CONSTITUTION:0.0005mol or less of tin or selenium is added to one mol of the temporarily sintered powder of a composition for positive characteristic(PTC) thermistor use, which consists of barium titanate ((Ba, Sr)TiO3) obtainable by replacing one part of barium with strontium, and after they are mixed, the mixture is molded and the molded product is fired in the atmosphere. Thereby, the temperature coefficient of resistance of the thermistor and the rate of change of resistance of the thermistor can be increased without changing the ratio of basic components of the PTC thermistor, by which a nominal resistance value of zero load specifying the field of use of the PTC thermistor is made to fluctuate.
