Abstract: Particles of a macro-porous ion exchange resin are dispersed in a solution of a transition metal compound, such as a compound of molybdenum, tungsten, or vanadium. The resin may be composed for anion exchange or cation ion exchange and, correspondingly, anions or cations of the metal are exchanged onto active ion exchange sites on the molecular chains of the resin. The resin is then carbonized and graphitized to form nanometer-size particles of transition metal carbide on particles of graphite. The composite metal carbide and graphite particles are electrically conductive and serve well as support particles for later deposited particles of a platinum group metal or other catalyst material in, for example, a catalytic electrode member in an electrochemical cell.

Abstract: A die detachment apparatus for partially delaminating a die from an adhesive tape on which it is mounted comprises a cover having a support surface that is operative to support the adhesive tape, the support surface including a set of cover holes. A movable pin chuck is positioned below the support surface and includes a set of pin holes that are arranged coaxially with the cover holes. The movable pin chuck is configured for detachably inserting a set of pins in a first desired configuration on some of the pin holes, and the pins are also operable to be relocated on the pin chuck to form another desired configuration. The pins are operative to protrude from the cover by passing through the cover holes to contact and lift the die.

Abstract: A vehicle-carried radiation inspection system has a simple structure with advantages of convenient operation, little scanning blind area and reliable safety performance. The system includes a loading vehicle, a lifting device mounted to the loading vehicle and a radiation scanning inspection device fixedly mounted to the lifting device so as to ascend/descend together with the lifting device. The lifting device is configured to enable the lifting device and the radiation scanning inspection device as a whole to be apart from the ground by a predetermined safety distance when the loading vehicle is moving, and to enable the minimum distance therebetween during inspection to be less than the predetermined safety distance. The radiation scanning inspection device may be switched between higher and lower positions as required with the ascending/descending of its combination with the lifting device.

The lifting device is configured to enable the lifting device and the radiation scanning inspection means as a whole to be apart from the ground by a predetermined safety distance when the loading vehicle is moving, and to enable the minimum distance therebetween during inspection to be less than the predetermined safety distance. According to the invention, the radiation scanning inspection means may be switched between higher and lower positions as required with the ascending/descending of its combination with the lifting device.

Abstract: The proposed holographic particle image velocimetry (HPIV) system employs holograms of two time-separated particle fields, illuminated by separate reference beams on a single recording medium. 90-degree scattering is utilized for the object wave, in order to improve Numerical Aperture and resolve the third dimension of the hologram. The proposed HPIV system then uses substantially the same optical geometry for the reconstruction process. A CCD camera is utilized to extract particle subimages, thin slice by thin slice, and a centroid-finding algorithm is applied to extract centroid locations for each volume. The concise cross correlation (CCC) algorithm for extracting velocity vector fields from the centroid data is an important enabling feature of the proposed system. Correlations are calculated between subsets of centroids representing the images or cubes, and velocity vectors are computed from the individual correlations.

Abstract: An electric gas discharge lamp includes an electrode having a tip portion comprised by a mesh body carrying an emitter material. The mesh body in a favorable embodiment is circular cylindrical and is attached via an electrically conductive thermal isolator to a conductive feed-through, such as a hollow ferrule, extending through a seal of the lamp vessel. As compared to a continuous walled tip portion of similar shape and material, the mesh body has a lower mass and heat capacity, and can therefore be operated at higher temperatures without increasing the temperature of the seal area. The higher operating temperature of the tip portion promotes greater electron emission from the emitter material, and therefore a lower cathode fall. A lower cathode fall enables the lamp to be operated at higher lamp currents for greater light output.
