Title: Antenna apparatus
Inventor: KONISHI YOSHIHIKO
IPC: H01Q21/29
Filed: 1994-11-15
Granted: 1999-03-23
Abstract: Herein is revealed a helical antenna apparatus wherein the direction of beam radiation hardly changes even if the frequency in use changes.  Two helical antennas which are wound with two conductive wires spirally, respectively, at equal intervals with a specified pitch .alpha. in the form of a cylinder are disposed along the length of the helical antennas so that the axes thereof substantially coincide with each other.  By determining the lengths of the feeders of the respective helical antennas appropriately in order to set the phase of supplied power, it is possible to form the beam of signals radiated into space in the shape of conical beam having a directivity oriented obliquely upward.  Additionally, it is possible to obtain the conical beam in which the direction of beam radiation does not change even if the frequency in use is changed.

Granted: 2007-05-29
Abstract: The specification discloses an automated apparatus and method for packaging surgical needles having sutures attached thereto wherein a bundle of needles and sutures are placed at a semi-automated separation station and an operator feeds the needles, one at a time, into a rotating needle feed wheel. As the feed wheel advances, the suture is tensioned and directed along a pre-determined path to separate it from the remaining sutures in the bundle. The apparatus has a plurality of individually rotatable tool nests which are sequentially spaced on a rotating or indexing turntable. These tool nests sequentially receive plastic packages for receiving the needle and suture at a first station. At a second station, a needle is inserted into the package by robotic fingers which have retrieved the needle and attached suture from the rotating needle feed wheel. The rotating needle feed wheel and the rotating tool nests are synchronized to step together as each advances. At a third station, the package and needle are rotated to tension the suture and position the package and the suture for automatic winding of the suture into the package. At a fourth station, the rotatable tool nest is rapidly rotated to wind the suture into a circumferential channel in the package which surrounds the needle. The package is optically expected to ensure orientation and position of the needle, and to ensure that the suture has been wound entirely into the suture receiving channel. At the next station, a cover attaching mechanism stakes a cover into the package using self-locking tabs defined between the package and the cover. The labeled package is then inspected, and off-loaded at the final work station to a tray which receives a plurality of suture packages for sterilization and final packaging. While the operation of the device is computer-controlled, most of the mechanical elements are driven from a single camshaft through a plurality of cams and cam followers. Unique mechanisms are also described to separate a single label from a stack of labels, and to transfer the label for staking on the package. A unique mechanism is described for removing the package from the tool nest and either discarding the package, if it failed one of the inspection steps, or placing the package into a carrier for sterilization and final packaging.

Title: Projecting images
Inventor: KNOX RICHARD M
IPC: H04N5/74
Filed: 1996-12-23
Granted: 2001-03-13
Abstract: An "extra-folded" projection display system includes a selectively reflective material (e.g., a linear reflecting polarizer) placed immediately behind the system's imaging screen.  The display system includes an image projector that projects an image beam containing light of a predetermined linear polarization toward the imaging screen.  The linear reflecting polarizer reflects the light in the image beam away from the screen.  The reflected image beam then encounters a 1/4-wavelength achromatic retarder which converts the linear polarization to circular polarization.  The image beam next hits a mirror that reflects the light back through the 1/4-wavelength achromatic retarder, which converts the circular polarization back to linear polarization, with the polarization director rotated 90° from the original polarization director.  The linear reflecting polarizer then allows the light to pass through to the image screen.

Abstract: A self-drilling stud particularly suited for use in normal weight or lightweight composite deck system where the use of standard weld studs is inappropriate because of the relatively thin material cross-section of the steel support member. The stud is heat treated to a dual-hardness level so that a portion of the stud is capable of drilling the support member and the decking.      The remaining portion of the stud remains relatively ductile so that it can withstand and transfer shear loads imposed by shifting of the concrete slab which overlies the decking to the main support members. The stud is a single piece fastener which includes specially formed annular flanges which enhance interlocking between the stud, the concrete slab and support members.
