Abstract: A method includes depositing a first work-function layer and a second work-function layer in a first device region and a second device region, respectively, and depositing a first fluorine-blocking layer and a second fluorine-blocking layer in the first device region and the second device region, respectively. The first fluorine-blocking layer is over the first work-function layer, and the second fluorine-blocking layer is over the second work-function layer. The method further includes removing the second fluorine-blocking layer, and forming a first metal-filling layer over the first fluorine-blocking layer, and a second metal-filling layer over the second work-function layer.

Abstract: A system includes one or more data processors configured to run a basic input/output system (BIOS) service and a bootloader configuration manager for tuning kernel parameters. The system further includes a non-transitory computer-readable storage medium containing instructions which, when executed on the one or more data processors, cause the one or more data processors to perform operations. The operations include receiving administrative inputs and checking the administrative inputs against a checklist to determine whether any errors are introduced by the administrative inputs. The operations further include writing the administrative inputs to a temporal configuration file in response to no errors being introduced by the administrative inputs. The operations further include exporting the temporal configuration file to a designated output path. The exported temporal configuration file includes kernel parameter settings for configuring a bootloader of a computing device.

Abstract: A photovoltaic power generation system includes a photovoltaic power generation module, a capacitor, a DC/AC voltage converter, a filter, a relay, a PWM controller, a calculation module, a control module, and a grid. The control module traces the maximum power of the photovoltaic power generation module, and detects whether the grid is abnormal or not. Finally, the DC power outputted from the photovoltaic power generation module is transferred to the AC power and outputted to the grid via the DC/AC voltage converter by using the PWM controller.

Abstract: A fall-proof structure to prevent the connecting rods of a lamp from falling down, in which the lower ends of the connecting rods each have a threaded end and two symmetrical lugs; the connecting rod is to be connected together with a threaded sleeve having a slot; the outer end of the threaded sleeve is mounted with an adjusting nut, a spring washer, and a washer; then, the threaded sleeve passes through a round hole of the base housing, and is mounted, inside the base housing, with a rotation-limiting disk, and a power-connecting plate; finally, the end of the connecting rod is mounted with a slip-resistant nut. The lower part of the base housing has a limiting groove for receiving the lug of the rotation-limiting disk. The tightness of the connecting rods can be adjusted by turning the adjusting nut; the rotation-limiting disk and the limiting groove in the base housing are used for preventing the connecting rods from falling down.

Abstract: A lamp shade structure for easily mounting a snap-socket; the socket has two symmetrical hook grooves on the outer lower part thereof to facilitate connection with a lower shade portion, which is cup-shaped member with a screw hole in the center thereof, and two symmetrical snap fasteners; each of the snap fasteners has a hook to be engaged with the corresponding hook grooves so as to have the socket mounted on the lower shade portion in a simple and snap manner.

Abstract: A desk lamp with adjustable lights mainly comprising a cone-shaped stationary base, a rotary head supporting member, a rotary head, a bow-shaped hollow arm and lamp housings; the rotary head is mounted on the top of the cone-shaped stationary base; the lamp housings are disposed at opposite ends of a bow-shaped hollow arm, which is attached to the rotary head; since the rotary head can rotate 360 degrees in horizontal direction, and pivot in the vertical direction with respect to the cone-shaped stationary base, the light of the lamp can be adjusted by a user; moreover, since the light of the lamp can be thrown first on the surface of the cone-shaped stationary base, and then is reflected to a desk surface, the light becomes much mild to a user than a direct light beam.
