Abstract: A method includes providing a substrate having a surface such that a first hard mask layer is formed over the surface and a second hard mask layer is formed over the first hard mask layer, forming a first pattern in the second hard mask layer, where the first pattern includes a first mandrel oriented lengthwise in a first direction and a second mandrel oriented lengthwise in a second direction different from the first direction, and where the first mandrel has a top surface, a first sidewall, and a second sidewall opposite to the first sidewall, and depositing a material towards the first mandrel and the second mandrel such that a layer of the material is formed on the top surface and the first sidewall but not the second sidewall of the first mandrel.

Abstract: A drag gain structure for the gravity wheel of fitness equipment includes an eccentric driving member disposed on the first side of the gravity wheel, which includes inner and outer side plate sections, and an interconnecting piece. The interconnecting piece is rotationally coupled to at least one of the plate sections. One end of outer side plate section is fitted over and fixed to the shaft, and one end of inner side plate section is connected to an eccentric position of gravity wheel through the first bias joint pin. A bearing pedestal is disposed on the second side of the gravity wheel, including a bearing screwed on the shaft, a pedestal shell fitted over the bearing and a radial protruding plate on the periphery of pedestal shell. The protruding end of the radial protruding plate is connected to an eccentric position of gravity wheel through the second bias joint pin.

Abstract: A magnetic control exerciser includes a base, a pulley device and damping device respectively disposed on the base. A first rope is coiled on the pulley device, wherein a first handlebar and a second handlebar are respectively transversally connected to a first end and a second end of the first rope. A second rope has two opposite ends respectively connected to the pulley device and the damping device for providing a damping and promoting the effect of the magnetic control exerciser in accordance with the present invention. The first handlebar has an original horizontal height higher than that of the second handlebar for providing different exercising modes. A seat is secured on the base for user to easily operate the first handlebar and the second handlebar.

Abstract: A rock climbing has a base placed flat on a bearing surface, a damping device mounted on the base, a pedal structure is connected to both sides of the damping device respectively and two rock climbing simulators upright fixed to the base. The two rock climbing simulators are mounted on both sides of the damping device respectively. Each rock climbing simulator is provided with a slide grip device, and each grip device is connected to a corresponding pedal structure. When the two pedal structures are trodden alternately, the corresponding grip devices reciprocate up and down, simulating the rock climbing action.

Abstract: An improved treadmill includes a pedestal, arm stand, drag wheel, two swinging rods and pedals, a stride regulating mechanism, and two elbow-type drive connecting rods. The arm stand is set vertically onto the pedestal's mounting surface. The drag wheel is pivoted axially onto the pedestal through a vertical framework. A mandrel is set transversely onto the center of the drag wheel. Two swinging rods have the pivotal end pivoted onto the pedestal and located at a spacing on two sides of the drag wheel. Two pedals are separately set onto the swinging ends of two swinging rods. Two elbow-type drive connecting rods are linked separately to the mandrel and two swinging rods of the drag wheel, and the stride regulating mechanism is set between two swinging rods. The treadmill has less driving members, lower manufacturing and assembly cost and better driving performance.

Abstract: A damper gear structure of a body-building apparatus features a unique structure with the central through-hole and driving shaft lever not contacting each other and forming a ring-shaped interval, and an additional configuration of a connecting and positioning member to combine the driving shaft lever with the damper gear main body. The damper gear can deviate the driving and connecting part beyond the outer diameter of the driving shaft lever to increase the lever arm when the driving shaft lever drives the damper gear main body, and achieves the same revolving inertia with a reduced outer diameter of the damper gear main body. In this way, the operational and production cost effectiveness are both improved. Moreover, due to the reduced outer diameter of the damper gear main body, the peripheral components can be closer or smaller, and consequently the body-building apparatus can have a light and handy design.
