Abstract:
A socket includes a plurality of protrusions circumferentially disposed around a circular top opening in a top portion of the socket, whereby upon insertion of a driving (or coupling) shaft of a spanner with square head portion into the square hole in the socket, the square head portion of the driving shaft will be respectively biased or thrusted by the protrusions and then smoothly guided or slid through a sloping surface tapered downwardly radially from the circular opening into the square hole for quickly coupling the driving shaft of the spanner with the square hole in the socket.A socket further includes plural bottom protrusions disposed around a circular bottom opening in a bottom portion of the socket, and eighteen faces formed in a hexagonal bottom hole of the socket for helping a quick coupling of a nut or bolt into the bottom hole of the socket.

Moreover, a metal-oxide-semiconductor transistor includes a substrate, a gate dielectric layer, a gate conductor layer and a repair layer. The gate dielectric layer is formed on the substrate. The gate conductor layer is formed on the gate dielectric layer. The repair layer is at least partially formed on a sidewall of the gate conductor layer.
Abstract:
The present invention relates to a method for gate leakage reduction and Vt shift control, in which a first ion implantation is performed on PMOS region and NMOS region of a substrate to implant fluorine ions, carbon ions, or both in the gate dielectric or the semiconductor substrate, and a second ion implantation is performed only on the NMOS region of the substrate to implant fluorine ions, carbon ions, or both in the gate dielectric or the semiconductor substrate in the NMOS region, with the PMOS region being covered by a mask layer. Thus, the doping concentrations obtained by the PMOS region and the NMOS region are different to compensate the side effect caused by the different equivalent oxide thickness and to avoid the Vt shift.
Abstract:
Switching mode power supplies (SMPS) and control methods used thereof are disclosed. An exemplifying SMPS is coupled to control an inductive device. The SMPS comprises a voltage divider and a peak controller. The voltage divider comprises a resistor and a controllable resistor connected in series through a connection node. The resistance of the controllable resistor is variable, controlled by a control signal. The voltage divider generates a limiting signal at the connection node based on a line voltage at a line voltage power node. The peak controller controls a peak current flowing through the inductive device according to the limiting signal.

A metal shell with printing patterns has a metal body, a printing layer and an electroplating layer. The metal body has an outer surface and an area. The printing layer is attached to the outer surface of the metal body to form the printing patterns and has an area smaller than that of the metal body. The electroplating layer is attached to the outer surface of the metal body at a region beside the printing layer.

The discharging/charging circuit charges based on a feedback signal relative to output of the power conversion system. A switching-disabling control signal is produced based on the charge of the discharging/charging circuit, to disable the power conversion system.
Abstract:
A mobile device and a method for sharing a hardware device thereof are provided. Two operation systems are executed on the present mobile device simultaneously, and an embedded controller is configured to communicate among the two operation systems and a shared hardware device of the mobile device. When one of the operation systems encodes an operating command into a uniform message and transmits the uniform message to the embedded controller, the uniform message is decoded into the operating command by the embedded controller such that the hardware device operates according to the decoded operating command. On the other hand, when the embedded controller receives input data from the hardware device, the embedded controller encodes the input data into the uniform message and transmits the uniform message to one of the operation systems. The operation system receiving the uniform message decodes the uniform message into the input data.
Abstract:
A method for gradually adjusting screen brightness when switching an operating system is provided. The method is used for gradually adjusting the brightness of a screen of an electronic device by a controller thereof when the electronic device is switched from a first operating system to a second operating system. First, an operating system switching signal is received. Then, a first brightness value of the first operating system is obtained. The screen brightness is gradually adjusted from the first brightness value to a predetermined second brightness value. Afterwards, the first operating system is switched to the second operating system, and the screen brightness is further adjusted from the second brightness value back to the first brightness value. Accordingly, a user can sense the switching of the operating system more intuitively and has enough time to get used to the change of the screen brightness and the displayed frame.
