  • Patent number: 9529155
    Abstract: Gradient index (GRIN) lens chips and associated small form factor optical arrays for optical connections, and related fiber optic connectors are disclosed. By aligning GRIN lenses within a GRIN lens chip, a more precise and reliable alignment may be achieved with respect to optical fibers than if a single conventional ferrule is utilized to align and secure both GRIN lenses and optical fibers. The GRIN lens chip may include a GRIN lens received and thereby aligned within a groove disposed between a fiber end and a terminal end of a GRIN lens holder body. The optical fibers may also be received and thereby aligned within a groove of a ferrule body. In this manner, when the GRIN lens chip containing the GRIN lenses is aligned with a ferrule body containing the optical fibers, then the GRIN lenses may be precisely located relative to the optical fibers.

    Abstract: Stacking porous and non-porous material layers involves applying vacuum to a first porous layer to stabilize same relative to a support structure. The support structure and/or a non-porous layer are moved to establish contact between the non-porous layer and the first porous layer. The first porous and non-porous layers define a sub-assembly. While applying vacuum to the sub-assembly, one or both of the support structure and a second layer are moved to establish contact between the second layer and the non-porous layer. Vacuum applied to the sub-assembly maintains positional stability of the sub-assembly layers relative to the support structure while the second layer is moved into contact with the non-porous layer. Vacuum is subsequently removed to facilitate transporting of the material layer stack. Material layers of a fuel cell, including first and second fluid transport layers and a membrane, are well suited for automated stacking.

  • Patent number: 6481094
    Abstract: A method of manufacturing a chip PTC thermistor utilizes a piece of conductive polymer having a PTC characteristic and metal foils formed by patterning and provided on the upper and the lower sides of the piece under pressure integrally into a sheet, making a hole part in the sheet, applying a protective coating serving as plating resist to upper and lower sides of the sheet, forming an electrode on the sheet by electroplating, and cutting the sheet into a chip. The protective coating is made of a material applicable at a temperature equal to or lower than the melting point of the conductive polymer. The processing temperatures at the step from the step of making a hole part in the sheet to the pre-processing step of the step of forming an electrode by electroplating on the sheet are not above the melting point of the conductive polymer.

  • Patent number: 6182357
    Abstract: A manufacturing method and apparatus for dicing printed circuit boards is disclosed that permits PCB's to be manufactured with greater component density and cut less expensively. The disclosed method includes forming a raw substrate to include conductive traces, mounting components on the substrate, testing the PCB and then cutting off the waste edges. The PCB can be formed and tested with components mounted on one or both sides of the PCB, and the waste edges can be cut off even with components mounted on both sides of the board. A workpiece fixture is provided that includes a recessed cavity into which PCB components extend. Double-sided boards can be cut using the disclosed workpiece fixture. The cavity includes a vacuum hole through which suction is provided to hold the PCB in place during cutting. Additional vacuum holes preferably are provided to hold the wings in place after they are removed.

  • Patent number: 5826331
    Abstract: A method of manufacturing a component formed of parts capable of being separated for reassembly around another component. The process starts by taking separate, e.g., rod and cap, forgings and coining or forging them together prior to machining. The mating surfaces of the forgings are formed with a ridge-groove or a dimple/lug-recess configuration giving them a self-locating ability. After machining, the forgings are fractured along the original division to obtain two uniquely matched surfaces that need no further processing before being reassembled, e.g., to form a connecting rod for an internal combustion engine.

  • Patent number: 5759468
    Abstract: A cube corner article and method of manufacturing the article from a series of unitary substrates. A plurality of pins are assembled to form a mold having an array of cube corner elements on a surface. Then, a replica of the cube corner element array is produced in a substrate suitable for forming retroreflective surfaces. Portions of the replica substrate material are removed. The removal of these portions forms at least one cavity bounded by side walls in the replica at a depth at least that of the cube cube corner elements. The replica is replicated to produce an additional directly machinable substrate suitable for forming retroreflective surfaces having at least one raised section having sidewalls at a height at least that of the cube corner elements. At least one raised section is directly machined to form an array of cube corner elements.

  • Patent number: 5737821
    Abstract: A method of producing a shaped fibrous fabric structure is similar to that described in the parent application, in that a continuous filament sheet is subjected to a needle punching action, segments are cut from the sheet and these segments are assembled to form an annulus, and then subjected to rotary motion under a reciprocating needling head and continuing to add segments to build up a stack of layers while at the same time continuing the needling action, and lowering the base of the stack relatively to the needling head. However, in a final step, one or more layers of segments are added to the top of the stack, and these are needled into the stack without lowering the stack. Furthermore, these additional layers are preferably made entirely of stapled fibers.
