Title: Recovery of high purity triniobium octachloride from niobium-titanium alloy scrap or ferroniobium
Inventor: ITO FUJITAKA
IPC: C01G33/00
Filed: 1989-06-27
Abstract: PURPOSE:To recover Nb3Cl8 of high purity by chlorinating NbTi alloy scraps or ferroniobium at elevated temperature and hydrogenating NbCl5 to remove Ta. CONSTITUTION:NbTi alloy or ferroniobium is directly chlorinated over 250 deg.C, preferably at 300 to 500 deg.C, and the chlorination is continued utilizing the reaction heat. Formed high boiling chlorides of Fe, Al, Ni, W or the like are separated, then low-boiling chlorides such as TiCl4, SiCl4 or other chlorides are distilled off, thus NbCl5 is purified by distillation at 254 deg.C. The purified NbCl5 is reduced with hydrogen gas at 400 to 600 deg.C, preferably at 580 deg.C to exclude out TaCl5 boiling at 242 deg.C from the system to recover Nb3Cl8 of high purity free from Ta.

IPC: H03B19/14
Filed: 1983-09-05
Abstract: PURPOSE:To make wide-band signal multiplication possible by providing a transistor TR, which cuts off a push-pull TR circuit of a high frequency multiplying circuit for a certain time, for this push-pull TR circuit. CONSTITUTION:A push-pull operation is performed by TRs 1 and 2 to cancel the generation of even-order higher harmonic components. The emitter of a TR3 is connected to emitters of two TRs 1 and 2 commonly. The bias potential due to resistances 6 and 7 is set to a value higher than that due to resistances 4 and 5 by a potential corresponding to an odd multiplier. Then, a current is flowed to TRs 1 and 2 only, for example, for periods shown in a figure, and the current is cut off for the other periods by the TR3. Since harmonic waves in multiplications other than triplication are reduced considerably in this constitution, selectivity characteristics of tuning circuits 8 and 9 are set relatively widely, and as the result, transmission characteristics having a wide group delay time characteristic are realized.
