Abstract: A miter saw includes a support mechanism for supporting a miter saw unit relative to a base in such a manner that the miter saw unit is both vertically and laterally pivotable. A position determining mechanism serves to selectively determine the position of the saw unit at any of positions including a vertical position where a saw blade is positioned substantially vertically relative to the base, and leftward and rightward pivoted positions where the saw blade is inclined laterally leftwardly and laterally rightwardly from the vertical position by a predetermined angle, respectively. The position determining mechanism includes movable side stopper members and fixed side stopper members on which the movable side stopper members abut, respectively. The movable side stopper members are mounted on a movable member which pivots laterally with the miter saw unit. The fixed side stopper members are mounted on a fixed member which is non-laterally pivotally movably mounted on the base.

Abstract: A machine for cutting a tube having a frame encompassing the tube on which supports are conducted and moveable in two vertically stacked axial directions on a plane running at a right angle to the tube longitudinal axis. At least two supports are driven exclusively in a single axial direction during the cutting process. A cutting head is mounted on each support, each cutting head having a disk milling cutter attached thereto. The disk milling cutters, which are rotary driven on a common cutting plane, simultaneously cut through the tube as the result of controlled movement of the supports in their axial directions. The disk milling cutters, moving in the same direction relative to the circumference of the tube, i.e. clockwise or counter-clockwise, simultaneously cut a section of the wall cross-sectional area of the tube. The machine also has clamping devices arranged in the vicinity of the disk milling cutters to secure the tube in place during the cutting process.

Abstract: A method and apparatus for curved-angle cleaving of optical fibers is presented. The method requires the introduction of a flaw in an optical fiber to be cleaved, and the application of predetermined stress and strain to the optical fiber in the vicinity of the flaw to cause curved-angle cleaving of the optical fiber at the flaw. More particularly, one embodiment of the method requires fixing first and second portions of the optical fiber, for example, by clamping, and introducing a flaw into the optical fiber between the first and second portions. Then, a substantially concentrated force is applied to the optical fiber between the flaw and the first portion of the optical fiber, on a side of the optical fiber opposite the flaw, in order to cause the optical fiber to cleave with a curved-angle cleave. Another embodiment of the method applies a substantially concentrated force to the fiber before introduction of the flaw.
