    摘要: A seamless locking drain connector structure of a metallic sink is provided. A water outlet of a bottom of the metallic sink is integrally formed with an annular ring extending outward from the bottom of the metallic sink. The annular ring is fixedly connected with a connecting sleeve. The connecting sleeve is formed with outer threads. An open end of a stepped trough of the drain connector is formed with a retaining rim portion relative to the bottom end of the connecting sleeve. The retaining rim portion is connected with a locking sleeve. The locking sleeve is formed with inner threads corresponding to the outer threads of the connecting sleeve. The inner threads mesh with the outer threads, such that the retaining rim portion of the drain connector is tightly locked to the bottom end of the connecting sleeve to connect with the annular ring and the water outlet.

    摘要: The present invention provides a tunable circuit for quickly optimizing an electrical field generated by the F-N tunneling operation. To optimize this electrical field, the charging of the positive charge pump is begun after the charging of the negative charge pump. The tunable circuit of the present invention provides a means to detect the optimal negative voltage at which pumping of the positive voltage should begin. The tunable circuit includes a resistor chain coupled between a first reference voltage and a negative voltage from a negative charge pump. When charging of the negative charge pump begins, a comparator compares the voltage at a node within the resistor chain to a second reference voltage. In accordance with the present invention, the node voltage within the resistor chain is equal to the second reference voltage when the negative voltage is equal to the voltage to be detected. Thus, the comparator generates a trigger signal when the voltage at the node decreases to the second reference voltage. This output signal triggers the pumping of the positive charge pump. By changing the resistance within the resistor chain, the positive charge pumping may be initiated at varying negative voltages. In the present invention, additional resistance is added to or removed from the resistor chain via metal options or switches.
