A novel zone melting method to purify industrial phosphorus is introduced. Since there is no chemical solvent for phosphorus, chemical extraction purification does not work for arsenic purification. Zone melting is a method for removing impurities from solid materials. This method with a special set.....

The invented double-balanced quadrature-input quadrature-output divider (QIQOD) is based on conventional multiplier-based regenerative dividers but employs four different feedback loops with appropriate phase shifts. By making use of quadrature phase outputs from any quadrature signal generator, the.....
