摘要： A process is described for the electrodepositon of copper on various surfaces. The process involves use of a nonconsumable counterelectrode. Of particular significance is the composition of the surface of the counterelectrode. The surface of the counterelectrode comprises iridium oxide and tantalum oxide. Such processes can be carried out at high speeds, with smaller and more efficient equipment and can use various copper compounds as a source of copper.

摘要： To regulate the DC input voltage to a deflection circuit, a saturable reactor winding is series coupled with an unregulated DC voltage, a diode, a flyback transformer winding and an input terminal of the deflection circuit. During retrace, the diode is forward biased and conducts input current to the input terminal. During trace, the opposite polarity trace voltage commutates off the diode and decouples the input terminal from the unregulated DC voltage at a varied instant within trace in accordance with the impedance of the saturable reactor winding. The average DC voltage across the diode fluctuates with diode conduction angle variations and maintains a regulated input voltage at the input terminal despite fluctuations in the unregulated DC voltage.
摘要翻译：为了调节偏转电路的直流输入电压，可饱和电抗器绕组与非稳压直流电压，二极管，回扫变压器绕组和偏转电路的输入端串联耦合。在回扫期间，二极管正向偏置，并将输入电流输入到输入端。在跟踪期间，相反的极性跟踪电压使二极管整流，并根据可饱和电抗器绕组的阻抗，将输入端子与未调节的直流电压在不同的瞬间解耦。二极管导通角变化时，二极管两端的平均直流电压波动，尽管未调节的直流电压有波动，仍保持输入端的调节输入电压。
