Abstract: A ball joint press for installation/removal of ball joints or bushings into/from suspension components of vehicles. In general, the press includes first and second frame portions, a spine/shaft coupling the first and second frame portions together, and actuators coupled to one of the first and second frame portions. The actuators are sized and spaced such that combined forces of the actuators minimize a bending moment (and bending stress) about the shaft. The actuators may also share a feed line that provides for equal pressure across both actuators. This reduces an axis of bending of the shaft, and causes the first and second frame portions to remain substantially parallel and the force in line with an axis of motion to install or remove the ball joint.

Abstract: The collapsible sawhorse comprises a cross tie, a first vertical support member, and a second vertical support member.

As non-limiting examples, the project may be a construction material such as a board to be sawed, a temporary work surface such as a sheet of plywood, or a tool such as a chop saw. The collapsible sawhorse may be fastenerless in that the collapsible sawhorse may be assembled and disassembled without using tools.

Abstract: A holding apparatus, in particular a chuck, for a substrate comprises a main body with a upper side, a carrier element arranged in a recess of the main body so as to be vertically movable such that it can be adjusted between a protruding loading position and a retracted clamping position, the carrier element comprising a support surface for placement of the substrate. The support surface has a smaller diameter than the main body. A lifting element lifts the carrier element to the loading position. The carrier element seals the recess such that a sealed cavity is provided between the main body and the carrier element, which cavity can have a negative pressure applied thereto which counteracts the effect of the lifting element.

The drive bit may be axially movable relative to the pick tool to engage and drive the fastener picked up by the pick tool. The device may include a tool changer having one side that is operably connected to the driver, and another side that is operably connected to a fastener-specific pick tool, in which the pick tool can be separated from the driver to permit quick-changeover to a different type of pick tool.

Abstract: A grinding apparatus has a hermetically sealed chamber defined by a portion of a holding surface which extends radially outwardly from a wafer, an outer wall surface of a first annular packing, a lower surface of a plate, and an inner wall surface of a second annular packing. A negative pressure is developed by suction forces applied from the holding surface, allowing the atmospheric pressure to press the plate toward the holding surface and causing the first annular packing to press an outer circumferential portion of the wafer against the holding surface. Since the outer circumferential portion of the wafer is pressed against the holding surface under the suction forces from the holding surface and the atmospheric pressure, the forces pressing the outer circumferential portion of the wafer against the holding surface are increased easily at a low cost without increasing the size and weight of the grinding apparatus.

Abstract: There is provided a wafer grinding method of grinding a wafer having an orientation flat for indicating a crystal orientation in the condition where the wafer is held on a holding surface of a chuck table.

The suction holding portion has a first cutout portion corresponding to the orientation flat, and the frame portion has a second cutout portion formed along the first cutout portion. The wafer grinding method includes a holding surface grinding step of grinding the holding surface by using abrasive members of a grinding wheel, and a wafer grinding step of grinding the wafer by using the abrasive members in the condition where the wafer is held on the holding surface ground by the abrasive members.

Abstract: Interchangeable reaction washer initially penetrates with outward bottom serration edges only during manual pre tightening. Slippage is thereby avoided at begin of the consecutive power torque wrench assisted full tightening of the nut and/or bolt head resting on it. As the load ramps up, the reaction washer flattens out and the bottom serrations gradually penetrate radially inwards. Reaction and actuation sockets of varying sizes matching a broad range of reaction washers and nut and/or bolt heads may be interchangeably snapped on a reaction coupling connected to the torque wrench housing. A clearance undercut underneath the reaction washer torque receiving flanges absorbs eventual debris to further assist unimpeded and fast coupling of the system. Radially oriented contact faces between reaction washer and reaction socket provide a snug contact unaffected by their toroidal movement during washer flattening and a force transfer free of radial force components.

Abstract: A disc brake piston retraction tool includes a reversible ratchet wrench, a first pressure plate assembly, and a second pressure assembly. In the process of retracting a piston, a first engaging notch of a first L-shaped elastic plate of a first buckle member and a second engaging notch of a second L-shaped elastic plate of a second buckle member are pressed against a first force output shaft and a second force output shaft to provide an anti-rotation effect. Thus, when an operating handle of the reversible ratchet wrench is pulled back, it will not link a ratchet wheel, so as to carry out an effective operation of retracting the piston.
