20140048519 | LASER PROCESSING APPARATUS - A laser processing apparatus including a processing head for applying a laser beam to a workpiece. The processing head includes a focusing lens and a collecting unit provided between the focusing lens and the workpiece for collecting debris generated by the application of the laser beam focused by the focusing lens to the workpiece. The collecting unit includes a suction source for sucking the debris and a suction line having one end connected to the suction source and the other end opening to the front side of the workpiece. The laser processing apparatus further includes a cleaning liquid supplying unit for supplying a cleaning liquid to the suction line. | 02-20-2014 |
20140305917 | LASER PROCESSING APPARATUS AND LASER PROCESSING METHOD - A laser processing apparatus includes a chuck table for holding a workpiece. A laser beam is applied to the workpiece. A laser beam oscillating unit oscillates the laser beam and a processing head having a focusing lens focuses the laser beam. A dust collecting unit collects debris generated by the application of the laser beam. The dust collecting unit includes a suction passage having an opening for allowing passage of the laser beam to be focused onto the workpiece by the focusing lens. The suction passage extends symmetrically with respect to the opening, and a vacuum source draws the debris. The suction passage has a first end and a second end selectively connected to the vacuum source. | 10-16-2014 |
20140311471 | CUTTING APPARATUS HAVING BLADE COVER - A blade cover covers a cutting blade mounted on a spindle. The blade cover has a bottom portion formed with an opening from which the lower end of the cutting blade projects. A cutting fluid is supplied to the upper surface of a workpiece in the periphery of the opening of the blade cover. A discharge opening is formed in the blade cover. Air is sucked from the discharge opening by a vacuum source. The cutting fluid supplied to the upper surface of the workpiece is taken from the opening into the blade cover in association with the rotation of the cutting blade and thereafter discharged from the discharge opening to the outside of the blade cover. Accordingly, scattering of the cutting fluid can be suppressed. | 10-23-2014 |
20150183130 | CUTTING APPARATUS - A cutting apparatus including a holding unit for holding a workpiece, a cutting blade having a peripheral cutting edge for cutting a workpiece, a spindle unit including a spindle for rotating the cutting blade, a blade cover mounted on the spindle unit for covering the cutting blade, the blade cover having a bottom portion formed with a slit for allowing projection of a part of the cutting edge of the cutting blade, and a cutting fluid supplying unit for supplying a cutting fluid to the upper surface of the workpiece on both sides of the slit. The cutting fluid is not directly supplied to the cutting blade, but it is supplied to the upper surface of the workpiece. Accordingly, there is no possibility that the cutting fluid may be scattered by the rotation of the cutting blade. | 07-02-2015 |

20100170184 | Brackets and Bracket System For Assembling Playground Equipment - A bracket system for assembling playground equipment includes a plurality of deck support brackets, at least two vertical frame brackets, at least two horizontal frame brackets, a swing bracket, and at least two ladder brackets. The deck support brackets secure horizontal deck support beams to vertical frame beams at first points along the vertical frame beams. The vertical frame brackets attach to at least two adjacent vertical frame beams at second points above the first points. The at least two horizontal frame brackets fix at least one horizontal frame beam to the at least two adjacent vertical frame beams at the second points; the horizontal frame brackets and the vertical frame brackets interconnect. The swing bracket fastens a swing support beam to the at least one horizontal frame beam at a third point along the at least one horizontal frame beam. The at least two ladder brackets connect a ladder to one of the horizontal deck support beams. A piece of playground equipment assembled with the bracket system and a method of assembling playground equipment with the bracket system also are disclosed. | 07-08-2010 |
