摘要： PURPOSE:To contrive to improve qualities of product and to miniaturize facilities, by forming a glass ribbon while impressing a electromagnetic field of direct current to a molten metallic bath, further advancing the ribbon on the surface of the molten metallic bath and cooling. CONSTITUTION:A bath 2 having a molten metallic bath 1 is equipped with electromagnets 4, 10 and 11 of direct current, respectively and provided with a linear induction motor 12, coolers 8 and 9. An advancing magnetic field is impressed to the molten metallic bath 1 by the motor 12 and driving force is generated through Lorentz force to lower the first bath face. When molten glass is fed to the first bath face, a glass ribbon in the target thickness is formed on the second bath face. Successively glass flow is suppressed by the electromagnets 4 and 10 and the glass is rapidly cooled by the coolers 8 and 9. Since distortion is decreased by suppression of glass flow, qualities of glass are improved. Facilities are shortened and miniaturized because of large temperature gradient of cooling.

摘要： PURPOSE:To obtain an opalescent glass exhibiting opalescent color by reflection, exhibiting also red-yellow color by transmission, by regulating the ratio of (B2O3+CaO)/(Na2O+K2O+Al2O3) and (CaO+BaO)/(Na2O+K2O), respectively among oxides contained in each specified amt. CONSTITUTION:The above described opalescent glass is constituted of 60-75% SiO2, 4-9% Al2O3, 0.5-15% CaO, 0-8% MgO, 0-10% BaO, 5-20% CaO+ MgO+BaO, 3-14% B2O3, 2-13% Na2O, 0-5% K2O, and 2-13% Na2O+K2O, by weight. Further, the compsn. of the opalescent glass is regulated essentially by >=1.2 weight ratio of (B2O3+CaO)/(Na2O+K2O+Al2O3) and >=1.0 ratio of (CaO+BaO)/(Na2O+K2O). This opalescent glass reflects particulary rays of light in the range from near ultraviolet region to visible region effectively, and transmits effectively the rays of light in the range from visible region to neat infrared region. Accordingly, the glass is effective for preventing decoloration and deterioration of interior products due to light such as solar rays in the range from near ultraviolet region to visible region.

摘要： PURPOSE:To produce thin glass without cutting glass ribbon or to produce thick glass at high workability, by forming a level difference between the surface of the baths for the upper stream and the downstream by the impression of an electromagnetic force to molten metal, thus adjusting the thickness of glass ribbon to a target thickness between the first and second levels of the upper and the downstream baths. CONSTITUTION:The flow rate of molten glass 10 is adjusted by a refractory tool 11 and the molten glass flows down on the horizontal surface 13 of the molten metal in the first bath from an end of a lip 12. The flowed down molten glass has low viscosity and proceeds forward while spreading on the first bath surface 13 forming glass ribbon 16 having a thickness corresponding to the equilibrium condition. Magnetic field moving in the direction toward downstream is generated by a linear motor 19 provided below the bath 17, thus a thrust exerts in the downstream direction of the molten metal forming in the downstream side a horizontal second bath level 20 higher than the level of the first bath. The glass ribbon formed to a thickness corresponding to the equilibrium condition has a target thickness when it reaches the second bath level 20 after flowing down the inclined bath surface 22. Then, the molten glass is cooled, and desired float glass is produced.

摘要： PURPOSE:To provide the subject paper containing a fluorinated pitch, etc., excellent in water repellency and resistance to water-containing alcohol, having an affinity to organic solvents except alcohol and useful for separation of an organic solvent from a water-organic solvent-based mixture. CONSTITUTION:A fluorinated pitch and/or a heat-treated fluorinated pitch is dissolved in a fluorine-based solvent (e.g. hexafluorobenzene) and a paper is treated with the resultant solution to obtain the objective paper. In addition, the concentration of the fluorinated pitch in the solution is preferably 2-10wt.%.

摘要： PURPOSE:To obtain a fluorinated pitch having high F/C ratio and uniform properties and useful as a humidity sensor, a positive electrode material for lithium cell, etc., by directly reacting fibrous pitch with fluorine gas at a specific temperature range. CONSTITUTION:The objective fluorinated pitch can be produced by directly reacting a coal-based or petroleum-based fibrous pitch (having diameter of usually about 5-20mum) with fluorine gas diluted to about 0.5-100% with preferably Ar gas, He gas, N2 gas, etc., at a temperature between 0 deg.C and the softening point of the pitch. The reaction is carried out preferably by continuously introducing a fluorine containing gas into a reactor containing a fibrous pitch and passing the gas through the reactor.

摘要： PURPOSE:To produce ribbon-like foam glass continuously and stably, by controlling stream of molten tin and preventing a powder raw material continuously fed to the surface of molten tin from dispersing to the bath surface. CONSTITUTION:A powder raw material 8 is continuously fed to the bath surface of molten tin 2 contained in a bath 1. The molten tin is made to flow at 50-300m/H flow velocity from the upper stream to the down stream below the powder raw material 8. The powder raw material 8 is prevented from dispersing to the bath surface. Consequently, ribbon-shaped foam glass 7 is continuously and automatically produced.
