Abstract: Insertion of light elements such as H,C, or N in the R2Fe17 (R=rare earth metal) series has been found to modify the magnetic properties of these compounds, which thus become prospective candidates for high performance permanent magnets. The most spectacular changes are increases of the Curie temperature, Tc, of the magnetization, Ms, and of coercivity, Hc, upon interstitial insertion. A preliminary product having a component R—Fe—C,N phase is produced by a chemical route. Rare earth metal and iron amides are synthesized followed by pyrolysis and sintering in an inert or reduced atmosphere, as a result of which, the R—Fe—C,N phases are formed. Fabrication of sintered rare earth iron nitride and carbonitride bulk magnet is impossible via conventional process due to the limitation of nitridation method.

All of the portions of the portable carrying apparatus are hingeably connected together so that they can be independently moved away from each other. The top lid portion is held in place against the CD holding portion of the portable apparatus through attachment means. With the top lid portion moved upwardly and away, the CD holding portion which holds a plurality of compact discs is exposed so that the user can take one or more of the compact discs and remove it from the CD holding portion. Thereafter, the CD holding portion itself can be moved away from the bottom CD player holding portion of the portable carrying apparatus.

Abstract: A pulley hub load cell assembled inside a hub opening of a pulley between a rolling element part and a pulley axle. The load cell has a body adapted to be placed inside the rolling element part and having an interior bore for insertion through the pulley axle. The body has at least one exterior location to be brought into contact with the rolling element part, and at least one interior location to be brought into contact with the pulley axle. The at least one exterior location and the at least one interior location of the body are spaced apart and offset such that a portion of the body there-between forms a cantilever configuration which is deformable when counter-loads are applied to the at least one exterior location and the at least one interior location of the body from the rolling element part and the pulley axle respectively.

Abstract: A carrier tape system for receiving, retaining and quickly releasing small components, such as singulated bare die or integrated circuit (IC) chips for automated assembly processing. The carrier tape system is comprised of a longitudinally elongated flexible carrier tape frame with a plurality of spaced apart aperture cavities and a pair of pressure sensitive adhesive tape rails affixed to one surface of the carrier tape frame with the adhesive surfaces facing into the aperture cavities of the carrier tape frame. Each PSA tape rail has a longitudinal linear side edge and a configured side edge, where the linear side edge is affixed to the surface of the of the carrier tape frame and the configured side edge extends into and overlaps the aperture cavities for adhesioning the back side of the small components. With the configured side edges of PSA tape rails, a range or adhesion levels can be achieved with the PSA tape rails in one fixed gap width location.

Abstract: A method of making permanent drawings and markings on a mosaic tile having a grid frame with a plurality of replaceable plastic tiles or tiles made of polycarbonate material. The method comprises the steps of providing a plurality of separate and replaceable tiles on a grid frame of the mosaic tile; providing an ink-jet printer having an ultraviolet stable ink; spraying the ultraviolet stable ink out from the ink-jet printer onto the plurality of replaceable tiles of the mosaic tile to form an image, and exposing an ultraviolet light on the image to cure the ultraviolet stable ink onto the plurality of replaceable tiles of the mosaic tile. The method further comprises the step of replacing an old tile with a new tile having the same marking or new markings as the old file. The method causes the ink to be embedded onto the files and remain in a very permanent state.

Abstract: A fiber optical circulator wherein optical fibers of three ports share one glass capillary, one collimator lens and one walk-off crystal. Three optical fibers lie on a plane in a glass capillary that is aligned with a collimator lens concentrically. A light fed into the fiber of port 1, which is off optical axis of collimator lens, is collimated with an angle &thgr; to the axis of collimate lens. The collimated beam is divided into two orthogonal components by a first crystal. A device group consisting of one Faraday rotator and one pair of Half Wave Plates transfers the State Of Polarization (SOP) of two components into the same. The angled part of a combined prism bent both beams to be parallel to optical axis of system. The lights pass through a second crystal without displacement due to their SOP. Their SOP receive 90° rotations by a round trip in followed Faraday rotator with help of a reflection film on the backside or a mirror.

Abstract: An apparatus for testing and measuring sensory thresholds in humans and animals, including an electronic algometer and a probe housing. A strain gauge is installed within the probe housing and having one end fixed thereto and the other end movable. A support member is attached to the movable end of the strain gauge and extends out from an opening on the probe housing. A pipette member is press-fitted to the support member, where a resilient string has one end attached to the pipette member and the other end has a uniform tip diameter for creating a uniform reaction when a force is exerted thereto. The strain gauge measures the amount of deflection responsive to the force applied from the nylon string onto the support member with the uniform tip diameter of the resilient string in contact with the skin area of the human or animal and generates an electrical output signal indicative of the pressure applied.
