  • Publication number: 20240153940
    Abstract: A semiconductor device includes a fin structure, a first conductive line, a second conductive line and a first conductive rail. The fin structure is disposed on a substrate. The first conductive line is arranged to wrap a first portion of the fin structure. The second conductive line is attached on a second portion of the fin structure. The second portion is different from the first portion. The first conductive rail is disposed in a same layer as the first conductive line and the second conductive line on the substrate. The first conductive rail is attached on one end of the first conductive line and one end of the second conductive line for electrically connecting the first conductive line and the second conductive line.

  • Publication number: 20240083723
    Abstract: A hand-held jack has a main body, including a frame on a grip, the frame having a shaft hole passing through a first chamber and a second chamber therein, a jacking member being fixed to a front end of the frame; and a slow-down device. The slow-down device includes a swing seat pushed by the first spring and mounted in the second chamber; at least one shaft clamp and at least one restricting plate urged by a third spring that are disposed in a first accommodating groove and a second accommodating groove of the swing seat for clamping a lift shaft; and an eccentric push member having an eccentric portion resting on the restricting plate and a push portion. When a workpiece is lifted by the hand-held jack, the slow-down device lowers the workpiece slowly.

  • Publication number: 20240082986
    Abstract: A corner clamp for woodworking includes a clamp body having a carrying seat, the carrying seat having a slide surface with an elongate guide hole and an anti-slip portion; a slider, having a frame-shaped base that includes a guide block, a press portion, an accommodating room and at least one receiving portion having a through hole; a chuck; at least one detent, having a detent body movable in the through hole; and an eccentric pull member, having a first eccentric portion relative to the detent. When the chuck clamps two boards, the eccentric pull member is pulled toward the chuck so that the first eccentric portion presses the detent to be in tight contact with the stop-slip portion to prevent the boards from loosening when the boards are clamped.

  • Patent number: 11923358
    Abstract: A device comprises a first transistor, a second transistor, a first contact, and a second contact. The first transistor comprises a first gate structure, first source/drain regions on opposite sides of the first gate structure, and first gate spacers spacing the first gate structure apart from the first source/drain regions. The second transistor comprises a second gate structure, second source/drain regions on opposite sides of the second gate structure, and second gate spacers spacing the second gate structure apart from the second source/drain regions. The first contact forms a first contact interface with one of the first source/drain regions. The second contact forms a second contact interface with one of the second source/drain regions. An area ratio of the first contact interface to top surface the first source/drain region is greater than an area ratio of the second contact interface to top surface of the second source/drain region.

  • Patent number: 11642760
    Abstract: A woodworking clamp having a connector is provided. Two ends of the connector are connected with two clamping members to constitute the woodworking clamp. The connector includes a housing, a receiving tube, a U-shaped buckle, a spring, and a button. When the end of a bar of the clamping member is fully inserted in a notch of the U-shaped buckle, the spring provides a force to return the U-shaped buckle to its original position to complete the locking. When the button is pressed down, that is, a hook of the U-shaped buckle is pressed down, a positioning pin of the bar is released from the receiving tube and the U-shaped buckle so that the bar of the clamping member can be pulled out from the connector.
