Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: Semiconductor device structures having gate structures with tunable threshold voltages are provided. Various geometries of device structure can be varied to tune the threshold voltages. In some examples, distances from tops of fins to tops of gate structures can be varied to tune threshold voltages. In some examples, distances from outermost sidewalls of gate structures to respective nearest sidewalls of nearest fins to the respective outermost sidewalls (which respective gate structure overlies the nearest fin) can be varied to tune threshold voltages.

Abstract: A method for calibrating a load testing machine includes a computational unit that is operable to carry out, in a fully automatic manner, an operation of calibration of the load testing machine in order to help reduce the cost of the operation of calibration of the load testing machine and to improve creditability thereof. The load testing machine, as well as a master load cell and a load reader thereof, is set in connection with a computational unit so that the computational unit is operable to directly output an instruction for an operation of the load testing machine and the computational unit is operable to directly record the load obtained with the load testing machine in the calibration and a corresponding calibration values from the force sensor of the testing machine. A set calibration parameters can be calculated and obtained for completing the calibration of the load testing machine.

Abstract: A control valve assembly structure for spray guns comprises a pistol body made up of water inlet and outlet conduits in fluid communication with a valve chamber having a control valve assembly mounted therein wherein the water inlet and outlet conduits and the valve chamber are respectively equipped with a first aperture, a second aperture, and a third aperture having a narrowed opening to form a stop seat for the abutting location of an end cover. The end cover has a receiving section and an actuating groove disposed therein for the accommodation of a valve seat and a spring element respectively, permitting a valve sleeve and a plunger flexibly pushed by the spring element to abut tight against a flexible valve whose water-sealing portion is stretched to tightly seal off the third aperture thereby, facilitating an even application of force thereon as well as an easier and economical processing thereof.
