  • Publication number: 20240387546
    Abstract: A semiconductor structure includes a first transistor and a second transistor. The first transistor includes a first fin structure and a first metal gate over the first fin structure. The first metal gate includes a first work function metal layer and a first gap-filling metal layer. The second transistor includes a second fin structure and a second metal gate over the second fin structure. The second metal gate includes a second work function metal layer and a second gap-filling metal layer. The first metal gate and the second metal gate provide a same work function. A width of the first metal gate is equal to a width of the second metal gate. A width of a top surface of the first gap-filling metal layer is greater than a width of a top surface of the second gap-filling metal layer.

  • Patent number: 8783431
    Abstract: A fast detachable side wheel device, comprising: a first wheel cover, a second wheel cover, a wheel body, and a movable component. Firstly, wheel body is fixed in first receiving groove of second wheel cover as a replaceable component. Through positioning of a dovetail groove of first wheel cover and a dovetail tenon of second wheel cover, thus vibration, collision, or detachment of wheel body due to outside force can be avoided. Then, the movable component is used to control the positioning or detaching states between first wheel cover and second wheel cover, thus achieving fast and labor saving assembly and detachment of side wheels.

  • Patent number: 8720006
    Abstract: A retractable pulling rod utilizing an elastic extension device, comprising: a pulling rod set, a plug set, and elastic extension device. The pulling rod set is provided with a first socket, a second socket, and a third socket, sleeved onto each other through their ends of small diameters, and each is provided with at least a positioning hole. A first plug and a second plug are disposed respectively at bottom ends of first socket and second socket, to dispose a protrusion tenon of elastic extension device in an indentation slot inside second socket. Through using elastic extension device to assist steel beads of first plug and second plug to position in or detach from positioning hole, retractable pulling rod is extended or retracted smoothly.

  • Patent number: 8549705
    Abstract: A hollow wheel set, comprising mainly a wheel rack, a hollow rotation wheel, a restricting sleeve, and a restricting and fastening ring. The wheel rack includes a fixing arm, on said fixing arm is provided with a wheel fork. The hollow rotation wheel is sleeved onto the wheel fork. One end of the restricting sleeve is a sleeve connection portion, while the other end is a ring-shape blocking portion. The sleeve connection portion is sleeved and fixed on the outer perimeter of the wheel fork, and is located between the wheel fork and the hollow rotation wheel. The ring-shape blocking portion is on a side of the hollow rotation wheel. The restricting and fastening ring is fastened around outer perimeter of the wheel fork, and is locate on the other side of the hollow rotation wheel, to reduce size and weight of the hollow wheel set.
