Conference Proceeding: Space-use radial line slot antenna in 8GHz band with honeycomb structure
[show abstract] [hide abstract]
ABSTRACT: We have analyzed the slot coupling on the honeycomb structure, designed and fabricated the RLSA at 8.4 GHz. The directivity of 36.0 dBi with the aperture efficiency of 63.7% is obtained at designed frequency 8.4 GHz. The gain with the radome agrees well with the gain of only RLSA.Antennas and Propagation Society International Symposium, 2008. AP-S 2008. IEEE; 08/2008 -
Article: Temperature measurements of polymer melts in the heating barrel during injection molding. Part 2: Three‐dimensional temperature distribution in the reservoir
[show abstract] [hide abstract]
ABSTRACT: A new method has been developed to measure the three-dimensional temperature distribution of polymer melts in the reservoir of the heating barrel in the dynamic state. The procedure involves the use of a small-sheathed thermocouple in the nozzle of the machine. The tip of the thermocouple can be varied in depth from the surface to the center of the nozzle. The polymer melt of a shot is found to have a three-dimensional temperature distribution dependent on the geometry of the screw and the order of shot. These results reflect clearly the thermal histories of the polymer melt in the channel of the screw during plastication and conveyance, and indicate part of the dynamics of injection molding. Further, these measurements contribute to optimization of the design for the screw and the process conditions.Polymer Engineering and Science 08/2004; 29(3):171 - 177. · 1.30 Impact Factor
