  • Patent number: 5586475
    Abstract: A rachet-type hand tool having a sleeve-like guide freewheelingly mounted about a main body portion of the tool. A main shaft is rotatably mounted within the interior of the main body. An upper end of the shaft is secured to a three-way rachet mechanism. An operating rod/socket coupler releasably couples tool implements such as screwdriver heads, hex heads and the like to the operating rod. A torque extension handle is releasably mounted to the upper end of the main body and is provided with short and long lever arms selectable for gripping by the user to obtain the desired torque. Finger holes are provided in the torque extension handle for rapid rotation of the tool for insertion or removal of a screw, bolt or the like when only very light friction is encountered. An opposite arm of the torque extension handle is easily removed and can be replaced by another torque extension arm.

  • Patent number: 5586925
    Abstract: An apparatus and method for artificially weathering large amounts of marble by use of a horizontally disposed drum having a stone lined interior surface. The drum houses a large quantity of marble having similar surface hardness together with a slurry of abrasive material including silica, clay, and gravel which operates to cushion the marble from chipping during tumbling of the marble. The stone lining of the drum absorbs the impact of marble to reduce or prevent chipping of the marble. The marble and slurry are rotated at a particular speed for a predetermined amount of time. Various types of acid can also be inserted into the mixture providing a faster processing time and surface etching not possible with straight abrasion techniques. The processed marble is removed from the drum and sliced in half so to provide two pieces of weathered tile each having a flat mounting surface.

  • Patent number: 5584146
    Abstract: In accordance with the present invention, a polishing pad useful for polishing a semiconductor-comprising substrate is disclosed. The polishing pad is constructed to include conduits which pass through at least a portion of and preferably through the entire thickness of the polishing pad. The conduits, preferably tubulars, are constructed from a first material which is different from a second material used as a support matrix. The conduits are positioned within the support matrix such that the longitudinal centerline of the conduit forms an angle ranging from about 60.degree. to about 120.degree. with the working surface of the polishing pad. One preferred method of fabrication the polishing pad is pultrusion, where the tubulars are pulled through a resin bath to apply a coating of resin and then through a series of dies in which the resin is cured to provide a support matrix around the tubulars.

  • Patent number: 5584752
    Abstract: A pair of supporting arms are rotatably attached to both ends of a fixed shaft. A supporting shaft extends across forward ends of the supporting arms and in parallel to the fixed shaft. A grinding roller on which an abrasive tape is arranged, and guide rollers sandwiching it are attached to this shaft. Axial centers of the grinding roller and the guide rollers are in an eccentric state. Thus when the guide rollers contact a color filter, a gap is given between the grinding roller and the color filter, and projections can be ground corresponding to the gap.

  • Patent number: 5582082
    Abstract: An open-end wrench for gripping a hardware element such as a hexagonal nut or the hexagonal head of a bolt is disclosed which allows the wrench to be used for rotational driving of the hardware element in either direction without requiring the wrench to be periodically removed, repositioned, and replaced on the hardware element in order to continue rotation of the hardware element in the desired direction. A retaining member having an opposing jaw is mounted onto a handle having a fixed jaw in a manner whereby the retaining member has simultaneous freedom of movement in both a linear direction and in a rotational direction between first and second positions. When the handle of the wrench is turned in one direction, the nut or the head of the bolt will be rotated, while when the handle of the wrench is turned in the opposite direction, the jaws of the wrench will slip over the nut or the head of the bolt in a ratcheting manner.

  • Patent number: 5582536
    Abstract: It is an object of the present invention to provide an apparatus and a method for manufacturing a wafer, which are the most suitable for meeting the requirement for the mirror grinding surface of the wafer's chamfering portion. As a result, when the ingot is sliced, a wafer being sliced is chamfered at the same time. And, it is also possible that before the ingot starts to be sliced by the blade, the grindstone is pressed against the outer periphery of the slicing position to form a V-shaped groove along the outer periphery of the slicing position, so that the chamfering can be performed.

  • Patent number: 5579753
    Abstract: A concrete cutting saw is provided for the cutting of grooves in the surface of wet concrete. The concrete saw generally comprises a motor driven rotating cutting blade mounted on a support structure. The concrete saw is supported during cutting by wheels, and has a skid plate with a slot through which the rotating cutting blade passes to cut the concrete. The cutting blade is mounted with a sound deadening blade housing and a number of shields and guards located about the skid plate. The skid plate is movably attached to the concrete saw and resiliently urged against the concrete during cutting so that it remains in contact with the surface of the concrete surrounding the cutting blade during cutting. The skid plate is constrained into a bowed configuration so that it is substantially flat during cutting. A variable speed transmission is drivingly connected to the wheels to propel the saw across the concrete during cutting.

  • Patent number: 5573442
    Abstract: An apparatus for measuring the width of a cutting blade in a linear motor is activated when the cutting blade is raised. A working pin is advanced and one end of a detecting pin is abutted against an edge of the cutting blade. Thereafter, the working pin is returned. The blade width is derived by deducting the number of inputted driving pulses in returning from the advanced position of the detecting pin. The cutting blade is polished each polishing cycle for predetermined times by polishing rollers. The width of the cutting blade is measured by blade width detecting means during each predetermined polishing cycle. The measurement value of the blade width is fed back into a control device so that the subsequent polishing time of the cutting blade with the polishing rollers is adjusted until it becomes appropriate. The expiration of the useful life of the polishing rollers is determined when a long polishing time is required.
