Abstract: A power tool is provided with selectable remote power inlet locations (18A, 15A) by providing conduits (16A) for transmitting power from the re-mote location to the power switch (20). The remote power inlet (18A) is firmly connected to the conduit so that it is pos-sible to support the weight of the tool by the remote power inlet. In some configurations, the power conduit or conduit cover (16A) serves as a trigger guard or hand guard on the tool grip. Both pneumatic and electrical versions are dis-closed.

Abstract: This invention provides automatic and reliable determination of the touch point of a clutch 20 controlled by an automatic clutch actuation controller 60. This invention determines the touch point upon power-up while idling the engine 10, with the transmission 30 in neutral and an input shaft brake 28 applied. The clutch actuation controller 60 gradually engages the clutch 20 so that the measured transmission input speed matches a reference speed signal preferably between 40% and 60% of the idle speed. If the actuation is slow enough, this reliably provides the degree of clutch engagement at a small torque matching the braking torque which is the touch point. If there is no previous knowledge of the touch point, the clutch 20 is applied at a fast rate and an approximate touch point is determined, then the clutch 20 is positioned below the approximate touch point and is again applied at a slow rate to more accurately ascertain the touch point. If there is previous knowledge of the touch point, the clutch 20 is positioned just below the old touch point and is applied at a slow rate to determine a new touch point. The new and old touch points may be combined to determine the updated touch point.

Abstract: A  single  needle  system  for withdrawing donated  blood, processing the blood to harvest components such as platelets, and returning processed blood to the donor through the single needle.          Processing is performed by a centrifuge which separates blood components into stratified layers with a buffy coat containing platelets and white blood cells stably interfacing a red blood cell layer. Blood is withdrawn during a draw cycle and returned to the donor during a return cycle.  A recirculation system is provided so that blood flows at a reduced rate through the processing system during the return cycle in order to minimize return cycle time while maintaining the stable position of the interface between buffy coat and red blood cell layers.   A storage bag receives processed blood during the draw cycle and blood is squeezed from the bag during the return cycle, a portion returned  to  the  donor  and  another  portion  entering  the recirculation path.  A pressure sensor is located in the return path to indicate an empty storage bag upon a precipitous drop in pressure.  In that manner an immediate switch to the draw cycle is made to further minimize return cycle time.  To still further minimize the return cycle time, flow resistance in the return path is minimized with more than 80% of the flow resistance in the return path associated with the needle.

Abstract: The printing operation of an ink jet printer is controlled based on the density of the image to be printed. Using the density, a required drying time for each swath of printed matter is determined based on the image density. Also using the density, a maximum print frequency of firing the ink jets is determined. The density is determined by filtering stored print data by dividing the print data into blocks and determining a maximum number of ON pixels in a block. Such filtering enables clusters of ON pixels to be detected thus providing a more accurate determination of the density.

Granted: 2004-05-25
Abstract: In the magnet motor stator, magnet insertion holes are provided, a pole is formed with a plurality of insertion holes, and flat magnets are inserted into the respective insertion holes.      From among stator core plates made by stamping a steel sheet such as a silicon steel sheet, a plurality of stator core plates without magnet insertion holes and a plurality of stator core plates with magnet insertion holes are alternately laminated.      The magnet is held only at the portion formed by laminating a plurality of stator core plates having magnet insertion holes. At this point, the portions formed by laminating stator core plates without magnet insertion holes are arranged at the upper and lower ends of the stator. The simple flat shape of the magnet ensures easy preparation. The need for the positioning operation upon attaching the magnets to the stator or the bonding operation using an adhesive is eliminated. It is thus possible to manufacture a stator at a lower cost, and to reduce the sire and weight of the magnet motor used for an electric bicycle.

Abstract: An artificial airway device (10) to facilitate a patient's lung ventilation comprises an airway tube (14) and a laryngeal mask (11) at one end of the tube (14). The mask (11) is of generally elliptical configuration, with an inflatable peripheral cuff (12) of flexible material around the edges of the mask (11), for sealed support of the mask (11) around the inlet to the patient's larynx (27). The mask (11) has an aperture (13) through which the airway tube (14) opens into the interior of the mask (11). The mask (11) also comprises a longitudinally directed bar (20), extending across the mask aperture (13), from the central upper edge or rim (21) of the mask aperture (13), to which it has effectively a hinged attachment, to the posterior rim (21) of the mask aperture (13), at which the bar (20) is free.   The hinged mounting of this bar (20) is so positioned at longitudinal offset from the distal end of the mask (11) (which locates in the upper sphincter or oesophageal inlet) that the introduction of an inserted endotracheal tube (29) will automatically engage and swing the bar (20) backward into camming engagement with the epiglottis (30), thus easily folding the epiglottis (30) backward against the wall of the laryngeal inlet and permitting undeflected insertional passage of the endotracheal tube (29) to and through the laryngeal inlet.

Abstract: A knit slide fastener stringer including a fastener tape knitted in a warp-knit ground structure and having along one longitudinal edge an element-attaching portion, and a continuous fastener element row knitted in and along the element-attaching portion of the fastener tape and secured by two or more wales of anchoring chain stitch yarns simultaneously with the knitting of the fastener tape.  In this knit slide fastener stringer, successive needle loops of each of the two or more wales formed of the anchoring chain stitch yarns press the continuous fastener element row toward the warp-knit structure of said fastener tape from the upper side, and successive sinker loops constitute part of the ground structure. And a number of warp-inlaid yarns are each laid in and interlaced with at least part of the successive sinker loops.  The result is that the ground structure of the element-attaching marginal portion is kept in accurate size to prevent the coupled fastener element rows from locally splitting.
