The memory array includes first and second ferroelectric memory devices formed along a gate electrode, a channel layer and a ferroelectric layer between the gate electrode and the channel layer. The ferroelectric memory devices include: a common source/drain electrode and two respective source/drain electrodes, separately in contact with a side of the channel layer opposite to the ferroelectric layer, wherein the common source/drain electrode is disposed between the respective source/drain electrodes; and first and second auxiliary gates, capacitively coupled to the channel layer, wherein the first auxiliary gate is located between the common source/drain electrode and one of the respective source/drain electrodes, and the second auxiliary gate is located between the common source/drain electrode and the other respective source/drain electrode.

Abstract: A separation and recycling method for recycling uranium and fluoride from a waste liquid sequentially and separately is disclosed. The method comprises a uranium-recycling process and a fluoride-recycling process. In the uranium-recycling process, an alkali metal compound or monovalent cation and a coagulant aid are added into the waste liquid to promote the precipitation of uranium. In the fluoride-recycling process, an alkaline earth metal compound, a strong acid and a coagulant aid are added into the uranium-removed waste liquid to precipitate fluoride. By means of the method of the present invention, the uranium and fluoride contents of the uranium-removed and fluoride-removed waste liquid are compliant with the effluent standards of the environmental laws.

Abstract: A power supply is used in a computer. The power supply includes a main power circuit, an auxiliary power circuit and a switching circuit. The main power circuit has a first main output terminal for outputting a first operating DC voltage. The auxiliary power circuit has an auxiliary output terminal connected to a standby circuit of the computer for outputting a standby DC voltage. The switching circuit is interconnected between the first main output terminal and the auxiliary output terminal. When the computer is in a power-off state, the switching circuit is shut off, and the standby circuit is powered by the standby DC voltage. When the computer is in a power-on state, the switching circuit is conducted, and the first operating DC voltage is transmitted to the standby circuit through the first main output terminal and the switching circuit so as to power the standby circuit.

Abstract: A power source includes a power input terminal, a filtering unit, a main circuit and a capacitor energy release circuit. The power input terminal receives an AC voltage. The filtering unit is connected to the power input terminal for filtering off noise contained in the AC voltage. The main circuit is connected to the filtering unit and a load. The AC voltage is filtered by the filtering unit and converted into an output DC voltage by the main circuit, and the output DC voltage is transmitted to the load. The capacitor energy release circuit is connected to the power input terminal, the filtering unit and a common terminal for detecting whether the AC voltage is received by the power input terminal. When the AC voltage is not received by the power input terminal, electric energy stored in the filtering unit is discharged.
