  • Patent number: 6651324
    Abstract: A process of manufacturing printed circuit boards which is useful in the formation of printed circuit boards containing both areas of thick conductive traces and areas of fine resolution conductors in a single conductive layer, and printed circuit boards formed from such a process. A conductive core is first fabricated containing areas of thick conductors on a relatively thin conductive base. The conductive core is then bonded to a sublayer such as “prepreg” with the thick conductive areas adjacent to the sublayer in order to form a relatively flat laminate. Proper bonding typically requires the use of high resin “prepreg” sublayer. In the alternative, an additional inner layer of pure resin cab be inserted between the conductive core and the insulating sublayer prior to bonding. After bonding, the conductive surface of the laminate is formed into printed conductor traces by methods known in the art.

  • Patent number: 6647629
    Abstract: A handle tool handle has two interlocking first and second hollow molded plastic parts. The first part is formed with a peripheral lip. The second part is formed with transversely disposed peripheral surfaces inwardly disposed of the peripheral lip. Each handle part is formed a first plastic material and with a molded over second softer plastic material which covers the hand grip portion but not the peripheral lip or the peripheral surfaces. A tool blade is disposed between the interlocked handle parts. Rivets and a grommet provide pressed engagement of the handle parts with tight sealing of the peripheral lip. The hollow handle parts have respective facingly opposed structural ribs having respective spacedly disposed free ends to maximize the pressing engagement and insure sealing the peripheral lip.

  • Patent number: 6643919
    Abstract: A semiconductor device package fabrication method is proposed, which is used for the fabrication of a semiconductor device package of the type having a core-hollowed portion that is typically used to house an optically-sensitive semiconductor device such as an image sensor or an ultraviolet-sensitive EPROM (Electrically-Programmable Read-Only Memory) device. The proposed method is characterized in the use of a support pillar, which is positioned beneath the lead frame when the lead frame is clamped between a top inserted mold and a bottom cavity mold, to help prevent resin flash on the lead frame during the molding of the core-hollowed portion.

  • Patent number: 6640681
    Abstract: The invention relates to a method and to a device that allows portions of similar slices to be obtained even if the product that is sliced is changed. To this end, the slice surface is monitored. Incomplete portions are transferred to a park position subject to the slice surface monitoring. The incomplete portions are transported in a positionally accurate manner from the park position back to the collecting zone if the slice surface monitoring element detects that slices are available that match the portion.

  • Patent number: 6575064
    Abstract: A method and apparatus for cutting segments from a long sheet (1) of multilayered elastomeric material. An initial opening is formed in the sheet without severing reinforcing cords (20) within the elastomeric sheet by a penetrator/separator (40). Two ultrasonic knives are inserted on either side of the penetrator/separator (40) and positioned to cut the sheet at a small skive angle &agr; with respect to the plane of the sheet being cut. Then the knives are moved to opposite edges of the sheet of elastomeric material.

  • Patent number: 6575069
    Abstract: The invention relates to a device for setting the cutting gap between a rotor, having cutting blades and rotatable about its rotor axis, and a counter-blade body, which carries a cutting edge, can be fixed in position and can be set relative to the cutting blades of the rotor for optimizing the gap by an adjusting mechanism acting perpendicularly to the rotor axis, the adjusting mechanism having a slide guided in a linear guide, and the linear guide being arranged at an angle deviating slightly from the parallelism to the rotor axis, and the counter-blade body being arranged on the slide in such a way that the parallelism of cutting edge and cutting blade is ensured, or a U-shaped counter-blade body being provided, the legs of which are pressed apart elastically by pressure elements for setting the cutting gap. Furthermore, the invention relates to a method of setting the cutting gap between a rotor and a fixed cutting edge.

  • Patent number: 6557446
    Abstract: Diagnostic strips of the kind which are exposed to biological fluids such as blood or urine to detect or monitor medical conditions are cut sequentially from elongated cards by a reciprocating shear blade. The cards may be ones which exhibit defective areas that should not be included in the finished strips. Blade motion seats each newly cut strip on a movable strip carrier which abuts the blade during the cutting operation. The carrier then travels a nondefective strip to a pickup location where it is precisely positioned and picked off of the carrier for emplacement in a housing. A strip with a defective area is carried further to a discharge location where it is released into a waste receptacle. This enables more economical manufacture of diagnostic strips by efficiently making use of nondefective areas of cards that have defective areas.

  • Patent number: 6553674
    Abstract: A utility knife which has a slidable blade carrier located within an internal chamber of a housing. When the blade carrier is extended it has mounted thereon an engaging block with this engaging block being biased by a single spring to an outer engaging position which will connect the engaging block with the innermost blade of the stack of blades and sliding movement of the blade carrier will result in that innermost blade to protrude from the housing. The engaging block is mounted by a pair of pins which are mounted on the blade carrier. Movement of the blade carrier is accomplished by a thumb button where the inner portion of the thumb button is laterally displaced from the outer portion of the thumb button in order to maximize the space within a blade storage chamber formed within the housing.

  • Patent number: 6513411
    Abstract: A die block assembly of the present invention includes an upper die (20), an unloading plate (40), a plurality of springs (60), and a plurality of spacer blocks (80). A plurality of receiving holes (30) is defined in the upper die, for receiving the springs. A plurality of rams (34) depends from the upper die, for stamping a workpiece (95). The unloading plate is movably connected under the upper die, and defines a plurality of through holes (42) for accommodating the corresponding rams therein. Each spacer block is a stepped cylinder which includes a base (82) and a protrusion (84) extending upwardly from the base. Each spring abuts the base of the corresponding spacer blocker. A height of each base is slightly greater than a maximize clearance between the upper die and the unloading plate. The spacer blocks prevent spring fragments produced in the stamping process from entering the clearance.

  • Patent number: 6513248
    Abstract: A pruner has a first elongated member and a second elongated member coupled to a metal plate. The metal plate has a central aperture, a forwardly extending blade and a rearwardly extending tang having a second aperture offset from the central aperture. A jaw is mounted on the first elongated member. A power lever having a first end and a second end. A first coupler pivotably mounted in the central aperture and coupling the first member to the plate, with a second coupler pivotably mounted in the second aperture and coupling the second member to the plate. The power lever is coupled to the first and second elongated members by a third coupler pivotably coupling the first end of the power lever to the second member and a fourth coupler pivotably coupling the second end of the power lever to the first member. The power lever forces the second member to move linearly toward the first member for pivotable movement of the blade and jaw in response to linear movement of the first and second members.
