Abstract: The present invention is related to an open-end wrench including a first jaw and a second jaw and a throat section connected between rear ends of the two jaws. A toothed section is disposed on the inner side of the first jaw. The toothed section has multiple sharp teeth and a wide tooth positioned behind the sharp teeth. The wide tooth has a largest width among all the teeth. The bottommost point of the throat section is spaced from a front end of the first jaw by a first length. The bottommost point of the throat section is spaced from the tooth crest of the wide tooth by a second length, which ranges from ? to ½ the first length. The toothed section has a length, which is about ? the first length. The width of the wide tooth is 0.325 to 0.375 the length of the toothed section.

Abstract: A clamping ratcheting wrench is disclosed that is capable of being opened and closed without slipping the wrench over the end of a nut to be tightened or loosened. This wrench overcomes many problems because it may be used on a nut that is in a very tight position where a traditional wrench would not fit, nor would a conventional wrench be capable of ratcheting. The ratchet is effected by individual ratchet segments that are held in place when the wrench is opened. One of the true advantages of the various aspects is that the ratchet can be opened and closed once the ratchet segments are aligned, such that the segments are secured in place to allow the wrench to be opened up without having all the segments fall out of the wrench. A first aspect of the invention discloses an interlocking ratchet piece design, while a second aspect of the invention discloses another ratchet piece design with structural channeling to secure the ratchet segments in alignment so that the segments do not come out of the wrench.

Abstract: A spin chuck in an apparatus for single wafer wet processing has structures at its periphery that, in combination with a supported wafer, form a series of annular nozzles that direct flowing gas from a chuck-facing surface of the wafer, around the edge of the wafer, and exhaust the gas away from the non-chuck-facing surface of the wafer, thereby preventing treatment fluid applied to the non-chuck-facing surface from contacting the edge region of the wafer. Retaining pins with enlarged heads engage the wafer edge and prevent it from being displaced upwardly when a high flow rate of gas is utilized.

Abstract: A sheet restrainer is used to restrain movement of continuously traveling glass sheet and includes arms on either side of the glass sheet. A driving device coupled to the arms moves the arms from a retracted position in which the arms are withdrawn from the glass sheet to an engaged position in which the arms are near the glass sheet and in alignment with each other. Rollers are connected to the arms and contact the glass sheet in the engaged position. A damping device applies an adjustable damping force to at least one of the arms dampening movement of the arm in the engaged position thereby restraining movement of the sheet. In a method of operation, the damping devices restrain angular and/or lateral movement of the sheet by transmitting movement of the sheet against the rollers into a resistive damping force of the damping devices.
