Title: Suture anchor installation tool
Inventor: NICHOLSON JAMES E
IPC: A61B17/04
Filed: 1988-12-14
Granted: 1993-04-20
Abstract: Abstract A novel suture anchor installation tool which comprises an elongated member having a first end and a second end and a slot extending from the first end towards the second end, the slot being sized to snugly accommodate the suture anchor's barb, whereby the suture anchor may be attached to the elongated member at the first end of the elongated member by fitting the barb into the slot so that the barb extends upward and outward from the first end of the elongated member, through the slot, with the body of the suture anchor engaging the first end of the installation tool.  In use, the suture is first attached to the suture anchor, and then the suture anchor is attached to the elongated member in the foregoing manner. Then the first end of the elongated member is pressed into a predrilled hole in the bone, forcing the suture anchor in ahead of it.  As the suture anchor is pressed into the bone, its barb engages the side wall of the bone and is forced to retract backwards into the elongated member's slot so that it extends somewhat parallel to the elongated member.  When the suture anchor bottoms out in the bone hole, and the elongated member is thereafter withdrawn, the barb's engagement with the bone wall will cause the suture anchor to separate from the elongated member, leaving the suture anchor (and its attached suture) anchored securely in the bone.

Abstract: A METHOD OF MANUFACTURING A POLYSILICON EMITTER  AND A POLYSILICON GATE USING THE SAME ETCH OF       POLYSILICON ON A THIN GATE OXIDE      ABSTRACT OF THE DISCLOSURE A method of making bipolar and MOS devices simultaneously using a single fabrication process.  In one embodiment of the invention, a silicon substrate is divided into bipolar and MOS regions.  A thin layer of gate oxide, having a thickness in the range of from approximately 150 angstroms to 300 angstroms, is thermally grown on the silicon substrate.  A thin layer of polycrys-talline silicon, having a thickness in the range of from approximately 500 angstroms to 1000 angstroms is deposited on the gate oxide layer to protect the gate oxide layer during subsequent processing.  Both the thin polysilicon layer and the gate oxide layer are removed from the bipolar region where the emitter is to be formed.  To maintain the integrity of the gate oxide layer during etching, a photoresist mask used during the polysilicon etch is retained during the gate oxide etch, and the gate oxide is etched in a buffered oxide solution.  A thick layer of polysilicon then is depos-ited on the bipolar and MOS regions of the silicon sub-strate, and the substrate is masked and etched for form-ing the emitter and gates of the bipolar and MOS devices, respectively.

Granted: 1992-08-25
Abstract: STANF.C81   PATENT                            DYNAMIC COUPLERS USING TWO-MODE OPTICAL WAVEGUIDES   --Abstract of the Disclosure An optical mode coupling apparatus includes an optical waveguide in which an optical signal at a signal wavelength propagates in a first spatial propagation mode and a second spatial propagation mode of the waveguide. The optical signal propagating in the waveguide has a beat length. The coupling apparatus includes a source of perturbational light signal at a perturbational wavelength that propagates in the waveguide in the first spatial propagation mode. The perturbational signal has a sufficient intensity distribution in the waveguide that it causes a perturbation of the effective refractive index of the first spatial propagation mode of the waveguide in accordance with the optical Kerr effect. The perturbation of the effective refractive index of the first spatial propagation mode of the optical waveguide causes a change in the differential phase delay in the optical signal propagating in the first and second spatial propagation modes. The change in the differential phase delay is detected as a change in the intensity distribution between two lobes of the optical intensity distribution pattern of an output signal. The perturbational light signal can be selectively enabled and disabled to selectively change the intensity distribution in the two lobes of the optical intensity distribution pattern.

Abstract: An electronic filter for filtering an electrical signal.  Signal processing circuitry therein includes a logarithmic filter having a series of filter stages with inputs and outputs in cascade and respective circuits asso-ciated with the filter stages for storing electrical repre-sentations of filter parameters.  The filter stages include circuits for respectively adding the electrical representa-tions of the filter parameters to the electrical signal to be filtered thereby producing a set of filter sum signals. At least one of the filter stages includes circuitry for producing a filter signal in substantially logarithmic form at its output by combining a filter sum signal for that filter stage with a signal from an output of another filter stage.  The signal processing circuitry produces an inter-mediate output signal, and a multiplexer connected to the signal processing circuit multiplexes the intermediate output signal with the electrical signal to be filtered so that the logarithmic filter operates as both a logarithmic prefilter and a logarithmic postfilter.  Other electronic filters, signal conversion apparatus, electroacoustic sys-tems, hearing aids and methods are also disclosed.
