  • MOS circuit for lowering forward voltage of diodes
    Patent number: 6717830
    Abstract: A circuit for lowering the effective voltage drop of a semi-conductor diode. The circuit includes a first Metal Oxide Semi-conductor (MOS) device connected in parallel with the diode. A bias voltage which is close to but lower than the threshold voltage is applied to the MOS device. When a forward voltage is applied to the diode, this voltage is added to the source to drain voltage of the MOS device which turns it on. The MOS device then bypasses the diode to effectively overcome the inherent forward voltage drop of the diode. The circuit is advantageously applied to a rectifier circuit to reduce input voltage requirements and improve the efficiency of the rectifier.

  • Method of manufacturing a brush head by way of an injection molding process
    Patent number: 6695414
    Abstract: The present invention relates to a method of manufacturing a brush head comprising a brush head body carrying bristle bundles, in particular for tooth brushes, by way of injection molding, in which a first plastic component is injected into a first mold cavity for forming a bristle carrier, and ends of bristle filaments projecting into the first mold cavity are encompassed by the first plastic component. In order to guarantee a complete filling of the mold and a favorable reproduction of the mold cavity geometry, but to avoid at the same time a penetration of plastic mass into ducts in which the bristle filaments are held, it is suggested by the present invention that the bristle carrier manufactured during the first step is relocated into another mold cavity, which is larger than the bristle carrier, and which is filled with a hard component.

  • Locking differential including improved clutch member and adapter sleeve
    Patent number: 6688194
    Abstract: A locking differential includes a pair of annular coaxially-arranged axially-spaced clutch members having adjacent faces that contain cam groove that receive a driving cross pin, cooperating locking lugs and grooves being provided on the adjacent faces of the clutch members for preventing relative rotation therebetween. The cross pin extends diametrically across a supporting sleeve that is non-rotatably mounted concentrically within the central chamber of the cylindrical housing of the differential, thereby permitting the differential to be retrofit into various differential casings.

  • Top contact VCSEL with monitor
    Patent number: 6678292
    Abstract: A vertical cavity surface emitting laser (VCSEL) and monitoring diode combination having reduced parasitic capacitance for use in high bandwidth communications systems. The VCSEL has both p-type and n-type contacts on the same face. This allows the VCSEL to be mounted on a monitor chip or diode without using a metal contact layer. In an embodiment wherein the VCSEL is soldered to the monitor chip for mechanical stability only a small metal pad no larger than the VCSEL is used. The reduction in metallisation results in a lower parasitic capacitance that in turn results in higher potential operational speeds.

  • Method and apparatus for aligning and cutting pipe
    Patent number: 6662457
    Abstract: A method and apparatus for aligning and cutting pipes to extract and install piping in industrial plants is characterized by the use of lasers on a ring for aligning the cutting tool. By adjusting the ring so that beams from the lasers strike specified targets at a remote location corresponding with a pipe end, a cutting location is defined so that the trimmed end of a first pipe will properly align with a remote pipe. When the pipes welded together, their ends will match, thereby minimizing stress in the pipe. A cutting tool can be provided directly on the ring so that the pipe can be cut without removing the ring.

  • Method for recording image information
    Patent number: 6633321
    Abstract: The invention relates to a method for recording image information on a data carrier which has a substrate that can have optically identifiable information written to it by the application of radiation, and an image-carrying area suitable for the application of information, in which the whole image information of an image to be recorded is applied to the image-carrying area. In order to increase the tamperproofness of the image to be recorded and the identifiability of the said image, without adversely affecting the brilliance and colour fidelity of the image, the invention provides for a portion of the image information that is to be recorded to be additionally written to the substrate with the aid of radiation.
