Abstract: A ceiling fan and a structure thereof are provided. The structure includes a blade holder, a plurality of blades, and a plurality of positioning elements. The blade holder includes a holder body and a plurality of support platforms. The holder body has a plurality of first matching structures spaced apart from each other. Each of the support platforms includes a first positioning structure. Each of the blades has a second matching structure and a second positioning structure. The second matching structures can be guided by the first matching structures, so that each of the blades is disposed at an installation position on one of the support platforms along an oblique track. When each of the blades is located at the installation position, the first positioning structures and the second positioning structures abut against each other.

Abstract: Methods of cutting gate structures, and structures formed, are described. In an embodiment, a structure includes first and second gate structures over an active area, and a gate cut-fill structure. The first and second gate structures extend parallel. The active area includes a source/drain region disposed laterally between the first and second gate structures. The gate cut-fill structure has first and second primary portions and an intermediate portion. The first and second primary portions abut the first and second gate structures, respectively. The intermediate portion extends laterally between the first and second primary portions. First and second widths of the first and second primary portions along longitudinal midlines of the first and second gate structures, respectively, are each greater than a third width of the intermediate portion midway between the first and second gate structures and parallel to the longitudinal midline of the first gate structure.

Abstract: A fingerprint identification apparatus, including a light path adjustment element, an optical filter layer, and an image sensor, is provided. The light path adjustment element is disposed on a transmission path of an image beam from a fingerprint of a user. The optical filter layer is disposed on a transmission path of the image beam from the light path adjustment element. The optical filter layer has openings. An inclined image beam in the image beam is obliquely incident to the light path adjustment element. The light path adjustment element adjusts a light path of the inclined image beam to be transmitted to the openings along a normal direction. The image sensor is disposed on a transmission path of the image beam from the optical filter layer. The image sensor has pixels. Positions of the pixels respectively correspond to positions of the openings.

Abstract: A folding combination tool kit includes two oblong friction plates connected in parallel by bolts and nuts to hold a set of tools, enabling the tools to be respectively turned about the bolts in and out of the space defined between the oblong friction plates, wherein a flat connector is pivoted to one of the bolts, and an auxiliary tool is detachably coupled to the flat connector, the flat connector having a pivot hole, which receives one bolt, two shoulders bilaterally disposed at one end, and a flat, stepped, coupling portion at an opposite end for holding the auxiliary tool, the auxiliary tool having a first end, which is stopped at the shoulders of the flat connector when the auxiliary tool is coupled to the flat connector, a coupling notch longitudinally disposed on the first end and forced into engagement with the coupling portion of the flat connector, a second end, and a locating notch at one lateral side thereof between the first end and the second end for engagement with the locating rod when the au

Abstract: A bicycle tool assembly which includes a hollow handle, a coupling block fastened to one end of the handle by a tongue-and-groove joint to hold a driving element, for example, an open-end spanner, a box-end spanner, a hexagonal wrench, a cabinet tip, a Phillips head tip, or a hexagonal head tip, and a tire repair tool slidably mounted in an opposite end of the hollow handle, the tire repair tool having a front hook for pulling a bicycle tire out of the rim, a tire pressure releasing pin in the middle for fastening to the valve of the bicycle tire to release the pressure of the inner tube, and a coupling tail engaged with a tapered hole in the hollow handle to hold the tire repair tool in the operative position.

Abstract: An adjustable spanner includes a connecting member which comprises a center tool hole for inserting a screw-driver for use as a handle, two horizontal openings longitudinally aligned on the same plane at two opposite sides by the center tool hole, two vertical screw holes spaced on the same side and respectively disposed in communication with either horizontal opening; and two symmetrical jaw plates connected parallel to the connecting member and respectively retained in either horizontal opening of the connecting member, having each a plurality of vertical mounting holes spaced in a longitudinal direction and alternatively connected to either screw hole on the connecting member by a respective screw, and side notches bilaterally spaced along the respective length for clamping on the workpiece to be turned.

Abstract: A bicycle pedal crank dismounting device for dismounting a bicycle pedal crank, comprised of a hollow screw member and a stop rod, the screw member having a hexagonal hole on one end, an expanded bottom hole on an opposite end, and an inner thread linked between, the stop rod being fastened in the expanded bottom hole on the screw member by a C-shaped retainer ring, whereby the crank is dismounted by driving the screw member into the crew hole on the crank with the stop rod stopped against the bottom bracket bearing axle after the crank lock screw was removed, and then driving the crank lock screw into the inner thread of the screw member to turn the crank out of the bottom bracket bearing axle in the reversed direction.

Abstract: A folding tool set includes a handle formed of two opposite oblong cover plates connected by a first screw bolt and a second screw bolt, a set of left-handed tools respectively pivoted about the first screw bolt between the cover plates, a set of right-handed tools respectively pivoted about the second screw bolt between the cover plates, a plurality of oblong spanners made to slide between the cover plates at different elevations and set to cover the sets of left-handed and right-handed tools within the handle, and at least one hexagonal tool bit respectively received within the handle between the set of left-handed tools and the set of right-handed tools.
