Abstract: A solar photovoltaic power generation panel mount has a solar photovoltaic power generation panel attached to a mount frame having a plurality of vertical and horizontal bars connected in a grid-like manner. Concrete foundations project upwardly from a mount installation surface at predetermined intervals in a right-left direction under front and rear sides of the mount frame, and the mount frame is supported by the concrete foundations so as to be positionally adjustable in the up-down and right-left directions by mounting brackets fastened to a top of each of the concrete foundations.

Abstract: A grooving machine efficiently and speedily forms different kinds of grooves on the surface of a plate work (W). The grooving machine comprises a work table (11) on which the work (W) is fixed, a frame (7), an X-axis slider (17) disposed above the work table (11) and horizontally movably supported by the frame (7), a Z-axis slider (19) vertically movably supported by the X-axis slider (17), a tool holder base (75) supported by the Z-axis slider (19), and different kinds of cutting tools (97A to 97C) attached to the tool holder base (75), for grooving the surface of the work (W). Any one of these cutting tools (97A to 97C) is indexed to a cutting position where the work (W) is grooved. The tool holder base (75) has a cutting liquid supply portion (109) for supplying cutting liquid to a cutting zone where the indexed cutting tool cuts the work (W), and a cutting liquid suction portion (111) for sucking and removing excessive cutting liquid.
