Abstract:
An adjustable coupling including an axle, a fixed toggle mounted around the axle to hold a first frame rod, two movable toggles turned about the axle to hold a second frame rod and a third frame rod respectively, two locating plates mounted around the axle and prohibited from rotary motion relative to the axle and coupled with the movable toggles through a respective toothed joint, two cam holders fixed to the axle at two opposite ends, and two mushroom cam mounted around the axle and engaged with the cam holders, when the mushroom cams are fully received into the cam holders, the movable toggles can be disengaged from the locating plates and turned relative to the axle to adjust the angular positions of the second and third frame rods relative to the axle.
Abstract:
An integrated circuit device having reduced-height gate stack is fabricated by using a patterned oxide hard mask to pattern the underlying metal layer. The oxide mask is removed and the patterned metal is subsequently used as a mask to etch the polysilicon layer.
Abstract:
A hand portable riveter includes a handle pivoted to a casing to move a pull shaft through a transmission mechanism, causing it to set a rivet or rivnut via a riveter tip assembly, wherein the transmission mechanism consists of a pressure bar pivoted about a pivot in the middle and having a front fork stopped around a neck portion on the pull shaft and a rear fork, and a roller mounted on the rear fork by a pin; turning the handle in one direction causes the pressure bar to press the pull shaft downwards; turning the handle in the reversed direction causes the roller turned along the casing to give a pressure to the pressure bar in lifting the pull shaft.
Abstract:
A field effect transistor is fabricated with an ion implanted silicide layer and a conducting diffusion barrier pad layer that acts as a diffusion mask. The dopants from the silicide layer are diffused into the substrate to form shallow source/drain regions.

Abstract:
The present invention relates to a multi-functional riveter, whose basic structural components include a body and a body head having a hollow upper portion with an extended hand grip. Located within the interior of the body head is a lever hinged thereto. The one end of the lever is connected to a transmission shaft which, in turn, is attached to a press handle extended and exposed to the outside of the body. The other end of the lever is coupled with a sleeve. The basic structures mentioned above are all indispensable parts of a riveter layout. The functional enhancement and improvement embodied in the present invention are based on specific mechanical arrangements designed to allow a rivet-pulling apparatus, a nut-pulling apparatus, and an anchor rivet apparatus to be integrally disposed within a riveter through its sleeve, resulting in a convenient and multi-functional riveter with the characteristics of a structural simplicity, among other things.
Abstract:
A freehub of a bicycle contains: a body fitted and rotating on a rotary shaft. A receiving sleeve is connected with the body and fitted on the rotary shaft, and the receiving sleeve includes an accommodation holder configured to accommodate a freewheel. A ratchet assembly is mounted between the body and the receiving sleeve, the ratchet assembly includes multiple chutes, and a central axis of a respective chute is not parallel to a central axis of the rotary shaft. A toothed ring is fitted between the fixing element and the body. The ratchet assembly includes multiple teeth, multiple engagement elements, and multiple resilient elements. A respective resilient element abuts against the respective chute and a respective engagement element, such that the respective engagement element is urged by the respective resilient element to linearly move toward the respective tooth so as to engage with the respective tooth.
Abstract:
A hinge structure includes a first base, a second base, a first linking rod, a second linking rod, and a torque assembly. The first linking rod has a first pivot part, a first sliding part, and a second pivot part. The first pivot part is pivoted to the first base, and the first sliding part is slidably connected to the second base. The second linking rod has a second sliding part, a shaft part, a third pivot part, and a fourth pivot part. The second sliding part is slidably connected to the first base. The third pivot part is pivoted to the second base. The second pivot part is pivoted to the fourth pivot part. The torque assembly has a sleeve part sleeved on the shaft part and a connection part connected to the second base. The sleeve part generates torque during rotation with respect to the shaft part.
