Abstract: A power supply unit supplies power to a load, and the power supply unit includes a power factor corrector, a DC conversion module, and an isolated conversion module. The power factor corrector is plugged into a first main circuit board and converts an AC power into a DC power. The DC conversion module is plugged into the first main circuit board and converts the DC power into a main power. The isolated conversion module includes a bus capacitor, the bus capacitor is coupled to the DC conversion module through a first power copper bar, and coupled to the power factor corrector through a second power copper bar. The first power copper bar and the second power copper bar are arranged on a side opposite to the first main circuit board, and are arranged in parallel with the first main circuit board.

Abstract: Disclosed herein are related to a memory system including unit storage circuits. In one aspect, each of the unit storage circuits abuts an adjacent one of the unit storage circuits. In one aspect, each of the unit storage circuits includes a first group of memory cells, a second group of memory cells, a first sub-word line driver to apply a first control signal to the first group of memory cells through a first sub-word line extending along a direction, and a second sub-word line driver to apply a second control signal to the second group of memory cells through a second sub-word line extending along the direction. In one aspect, the memory system includes a common word line driver abutting one of the unit storage circuits and configured to apply a common control signal to the unit storage circuits through a word line extending along the direction.

Abstract: A hinge includes a base, an arm, a mounting member, a hinge spring, a fixing pin member, and a damping device. Two ends of the arm are pivotably connected to the base and the mounting member, with the hinge spring exerting elastic force on the base and the arm. The damping device is mounted in the base and includes a fixed seat mounted in the base, a sliding block movably received in the fixed seat, a damping member mounted between the sliding block and the fixing pin member and abutting the base, and an elastic element. The sliding block includes a front portion facing the arm and a rear portion connected to the elastic element pressing against the fixed seat.

Abstract: A hinge includes a base, a crank, a bottom board, a crank engagement seat, and a fixed seat. The crank is pivotably connected to the base. The bottom board includes at least one retaining portion, a first rivet hole and a vertical elongated hole. The crank engagement seat is connected to the crank and located between the fixed seat and the bottom board. The crank engagement seat includes first and second through-holes and a second rivet hole. The fixed seat includes first and second adjusting holes. A first adjusting member is extended through the first adjusting hole and the first through-hole into the first rivet hole. A second adjusting member is extended through the second adjusting hole into the second rivet hole. The bottom board and the crank engagement seat can be slightly moved in the vertical direction. The crank engagement seat can be slightly moved in the horizontal direction.

Abstract: A hinge includes a base, an arm, and an elastic element. The base includes a recessed body having a rear wall with a supporting portion. The arm includes a pivotal portion and two cam portions. A first pin section of a fixing pin member is extended through the pivotal portion and connected to the base. The elastic element includes two front elastic portions, a rear elastic portion, two intermediate portions each interconnected to one of the front elastic portions, and two extensions each interconnected between the rear elastic portion and one of the intermediate portions. The front elastic portions press against the cam portions. The intermediate portions are connected to the base by a second pin section of the fixing pin member. The rear elastic portion abuts the supporting portion of the rear wall.
