Abstract: A semiconductor device with dual side source/drain (S/D) contact structures and a method of fabricating the same are disclosed. The method includes forming a fin structure on a substrate, forming a superlattice structure on the fin structure, forming first and second S/D regions within the superlattice structure, forming a gate structure between the first and second S/D regions, forming first and second contact structures on first surfaces of the first and second S/D regions, and forming a third contact structure, on a second surface of the first S/D region, with a work function metal (WFM) silicide layer and a dual metal liner. The second surface is opposite to the first surface of the first S/D region and the WFM silicide layer has a work function value closer to a conduction band energy than a valence band energy of a material of the first S/D region.

Abstract: A lubricatable ball spline device includes a ball spline shaft, a ball nut slidably sleeved on the ball spline shaft and having oil guide holes, a linear bearing unit mounted between the ball spline shaft and the ball nut, a bearing ring rotatably sleeved on the ball nut and having an oil supplying hole, a positioning portion disposed between the bearing ring and the ball nut, and an oil passage corresponding to the oil supplying hole. The oil supplying hole, the oil passage, an oil storage space of the positioning portion and any one of the oil guide holes cooperatively form a continuous oil path.

Abstract: A lubricatable ball screw device includes a ball screw shaft, a ball nut slidably sleeved on the ball screw shaft and having oil guide holes, a linear bearing unit mounted between the ball screw shaft and the ball nut, a bearing ring rotatably sleeved on the ball nut and having an oil supplying hole, a positioning portion disposed between the bearing ring and the ball nut, and an oil passage corresponding to the oil supplying hole. The oil supplying hole, the oil passage, an oil storage space of the positioning portion and any one of the oil guide holes cooperatively form a continuous oil path.

Abstract: A harmonic drive featuring helix-facilitated lubrication includes a circular spline, a flexspline, a wave generator, and an agitating member. The flexspline meshes with the circular spline. The wave generator has a bearing installed within the flexspline, an elliptic wheel positioned in the bearing, and a shaft coupling connecting the elliptic wheel. The agitating member is located in a lubricant-holding space between the wave generator and the flexspline, and has a rotatory part and blade parts formed about a rotatory part. The rotatory part of the agitating member is connected to the shaft coupling of the wave generator, so that when the agitating member is driven by the shaft coupling, the helical blade parts agitate lubricant to perform convection, thereby better lubricating the bearing of the wave generator.

Abstract: The present invention relates to provide an air-guiding cover, comprising: an inner ring; an outer ring being arranged around the inner ring and defining a windward plane between the outer ring and the inner ring; and a plurality of air-guiding fins being arranged in the inner ring. The air-guiding fins have an inclination with respect to a normal axis of the windward plane, and the inclination increases progressively as the air-guiding fins extend from the inner ring toward the outer ring.

Abstract: A waterproof structure of a handheld lamp installed at a power socket includes a base having an accommodating space, a circuit board installed in the accommodating space, a port soldered to the circuit board and corresponsive to a slot of the base, and a thermosetting gel covered onto the port and the soldered portion of the circuit board and the port. The base has a corresponding cover made of a thermosetting gel by injection, so that the cover is packaged into the base, and the circuit board and the port are packaged in the base and the cover, and an interface of the port will not produce any gap. Therefore, moisture or dust will not enter from the interface to achieve the waterproof and dustproof effects.

Abstract: A cold/hot air radial and circulatory delivery device, comprising a cylindrical shell, which comprises a base part, an air inlet part, a middle electromechanical gear, an airflow suction motor, an air outlet part, and a circuit distribution area. The base part is set under the cylindrical shell so as to erect the cylindrical shell on the ground. The middle electromechanical gear includes a cooling/heating apparatus. An airflow guiding plate is set on the airflow outlet, wherein the guiding plate is a cone whose center is concave, making the profile of the guiding plate form concave arcs surrounding the cone in a V-shape, whereby when the guiding plate is placed on the cylindrical shell, the cooled/heated air can smoothly blow forth radially in a wide angle, equalizing the ambient temperature effectively through circulating currents.

Abstract: The invention provides a wind direction cover of an electric fan, comprising a central cap, an external circular frame, a plurality of wind guiding blades between the central cap and the external circular frame which are concentric with the central cap, and a plurality of anchor plates of the wind guiding blades. The exterior side of the most internal wind guiding blade is parallel to the flank of the central cap, and the exterior sides of external wind guiding blades slant toward the external circular frame, angulating the exterior sides of the wind guiding blades with the parallel plane of the flank of the central cap, and the more external the wind guiding blade is, the larger its angle slanting toward the external circular frame is.
