  • Publication number: 20130065053
    Abstract: Disclosed are composite pellets for extrusion molding wherein fusion does not occur between the pellets, and there is no variation in size and density. A molten material obtained by an extruder for a raw material containing a thermoplastic resin and wood powder is extruded into a strand shape through a die nozzle of the extruder, and cut into a predetermined length to form a pellet. At this time, the extrusion amount, the diameter of each nozzle hole, and the number of nozzle holes are adjusted so that the linear velocity (?d) of the molten material in each nozzle hole of the die nozzle is in the range of 12 to 50 cm/sec. Further, regardless of the variations in particle diameter, etc., a stable amount of the composite pellets are supplied to the extruder, and smoothly introduced to a screw of the extruder. The composite pellets and 12-hydroxystearic acid containing a metal of Ca, Mg, or Zn are agitated together, and 0.03 to 0.

  • Publication number: 20130028187
    Abstract: During a transition procedure from a first communication system to a second communication system, when the priority of a second communication call, whose setup is requested, is the first priority, the second communication system does not set up the bearer of a first communication call between the second communication system and the mobile communication terminal, and notifies the first communication system that the setup of the first communication is not possible, but the setup of the second communication call is possible. When notified that the setup of the first communication is not possible, but the setup of the second communication call is possible, the first communication system aborts the handover procedure, and instructs the mobile communication terminal to switch to the second communication system by another procedure.

  • Publication number: 20120318669
    Abstract: Provided is a sputtering target-backing plate assembly where a raw material powder prepared so as to have the composition of a magnetic material sputtering target is filled in a die together with a backing plate and hot-pressed, thereby being bonded to the backing plate simultaneously with sintering of the magnetic material target powder. It is an object of the present invention to provide a sputtering target-backing plate assembly having a high average pass through flux and allowing more stable sputtering, by disposing the raw material powder for a target on the backing plate and sintering them. By simultaneously performing sintering and bonding, a sputtering target-backing plate assembly has a shorter manufacturing process, can shorten manufacturing period, and does not cause a problem of detachment due to an increase in temperature during sputtering.
