Title: Device for charging and discharging current
Inventor: YONEMARU MASASHI
IPC: H03L7/093
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To operate with voltage that is higher than the withstand pressure of a single transistor and also to improve an output constant current characteristic by serially connecting each transistor between a power source and a ground potential and specifying each gate voltage. SOLUTION: In a charge pump circuit of a PLL, an output transistor is a cascode structure and also respectively selects gate voltage of each transistor. That is, plural MOS transistors 1 and 2, and 3 and 4 are cascaded between a power supply terminal and an output terminal and between the output terminal and a ground terminal respectively. Bias voltages which bring the transistors 1 and 4 into a saturation state are applied to the gates of respective 1st transistors 1 and 4, and also, voltage of a voltage level which brings the transistors 2 and 3 into a saturation state or non-conductive state is switched and applied to the gates of 2nd transistors 2 and 3 in accordance with the on/off of a pulse. Thus, a PLL circuit having high performance which acquires constant current in a wide range is obtained.

The Fe in the coating liquid in the removing vessel 7, then, attains the supersatd. state by as much as a difference in solubility. The Fe combines with the Zn and Al in the coating liquid and crystallizes as an intermetallic compd., i.e., dross. The clean liquid obtd. by separating away this dross is returned to the coating cell 3. This clean liquid is kept at the temp. equal to the temp. of the coating liquid in the coating cell 3 and attains the state that the Fe is not satd.  As a result, not only the suspended dross but the dross deposited in the bottom as well are efficiently removed.
