The present invention features a reciprocating wire saw particularly adapted or configured for cutting hard materials. In one aspect, the reciprocating wire saw comprises (a) a flexible wire; (b) a plurality of cutting segments fittable onto the flexible wire, wherein each of the cutting segments comprises an outer surface; and a (c) plurality of superabrasive particles braze bonded onto the outer surface of the cutting segments to form a cutting wire. In another aspect, the reciprocating wire saw comprises a plurality of superabrasive particles braze bonded directly to the wire itself to form a cutting wire. The cutting wire is unique in that it comprises a pre-determined superabrasive particle concentration and is configured to cut various materials, such as granite, in a reciprocating manner.

Reciprocating wire saw for cutting hard materials

The present invention discloses a CMP pad dresser which has a plurality of uniformly spaced abrasive particles protruding therefrom. The abrasive particles are super hard materials, and are typically diamond, polycrystalline diamond (PCD), cubic boron nitride (cBN), or polycrystalline cubic boron nitride(PcBN). The abrasive particles are brazed to a substrate which may be then coated with an additional anti-corrosive layer. The anti-corrosive layer is usually a diamond or diamond-like carbon which is coated over the surface of the disk to prevent erosion of the brazing alloy by the chemical slurry used in conjunction with the CMP pad. This immunity to chemical attack allows the CMP pad dresser to dress the pad while it is polishing a workpiece. In addition to even spacing on the substrate, the abrasive particles extend for a uniform distance away from the substrate, allowing for even grooming or dressing of a CMP pad both in vertical and horizontal directions. A method of producing such a CMP pad dresser is also disclosed.

A decomposable ROM image sequentially including an OS header corresponding to an OS image, the OS image, a non-OS header corresponding to a non-OS image and the non-OS image. To compose the decomposable ROM image, the OS header, which includes OS size information of the OS image and the non-OS header, which includes non-OS size information of the non-OS image are created first. Then, the OS header, the OS image, the non-OS header and the non-OS image are sequentially combined. To decompose the decomposable ROM image, the OS image is retrieved from the ROM image according to the OS size information obtained from the OS header. The non-OS image is then retrieved from the ROM image according to the non-OS size information obtained from the non-OS header.

A motorcycle rear wheel brake pedal comprises a brake tread rod, a tread plate, a tread plate base, a fastening plate, and a fastening element. The brake tread rod is fastened at one end thereof with a motorcycle frame and is provided at another end thereof with a pedal seat on which the fastening plate is retained securely. The tread plate base is secured to the upper surface of the fastening plate and is provided on the upper surface thereof with a plurality of skidproof elongated ribs fastened thereto. The tread plate is provided with a plurality of elongated through holes corresponding in location, number and shape to the skidproof elongate ribs of the tread plate base. The tread plate is fastened to the tread plate base such that the skidproof elongate ribs of the tread plate base are received in and jutted out of the elongate through holes of the tread plate for providing the tread plate with a skidproof surface.

An improved brake lever includes a lever body, a protective strip and a cap. The lever body is provided with a longitudinal slot which has a narrowed slit merged into the lever body at both ends of the longitudinal slot. The protective strip can be readily received and retained with the longitudinal slot. The end portion of the lever body has a flat portion which is provided with a dowel hole. The dowel hole has a narrowed inlet. The bottom side of the cap is incorporated with a bead. By this arrangement, the bead of the cap can be readily received and retained by the dowel hole. Accordingly, a compact and firm engagement is ensured between the cap and the lever body. Consequently, an improved brake lever with above described advantages is achieved.

A improved footrest includes a supporting bracket which is made from rigid material and a supporting stuffing which is made from soft material. The first supporting bracket has a hollow chamber at its center and is provided with a plurality of elongate slots formed in its wall. The supporting stuffing has a passage defined in the center and a plurality of projecting ribs formed on its outer surface in alignment with the slots of the supporting bracket. A shaft member is received and retained within the passage of the supporting stuffing to provide a rigid support to the supporting stuffing and the supporting bracket. The shaft member has a cylindrical recess at one end and a hole is provided through the outer wall of the shaft member such that the hole is in communication with the recess. A connecting adaptor has a lug at one end and a shaft at the other end. The lug of the connecting adaptor has a hole therein and can be attached to a frame of the motorcycle using a bolt and a nut. The shaft of the connecting adaptor is provided with an annular slot in alignment with the hole of the shaft member. Accordingly, the connecting adaptor is rotatably retained within the shaft member by utilizing a dowel screw which passes through the hole of the shaft member and projects into the annular slot of the shaft of the connecting adaptor. Accordingly, an improved footrest assembly which provides excellent support and frictional contact is achieved.

Footrest assembly for motorcycle

A footrest including a supporting bracket pivotally mounted to a motorcycle by a supporting bracket assembly. An elongate slot is formed in an upper surface of the supporting bracket, and a receiving chamber is formed in an underside of the bracket, the slot and chamber being in communication through a plurality of holes formed therebetween in the bracket. A resilient pad is disposed in the elongate slot, and a reflective rod is disposed within the chamber. A plurality of dowel posts project from the underside of the resilient pad and extend through the holes between the slot and the chamber to engage the reflective rod such that the pad and the reflective rod are retained in the supporting bracket.
