  • Publication number: 20240066776
    Abstract: A material discharge device includes: a drive motor; a screw having a groove formation surface and configured to rotate; a barrel having a facing surface and formed with a communication hole through which a plasticized material flows; a heating unit configured to heat the material; a nozzle from which the material is injected to an outside; and a plurality of measurement units configured to measure a pressure or a temperature of the material. The measurement units are disposed at an outer periphery of a nozzle channel wall, and a thickness of the nozzle channel wall satisfies the following (1) or (2): (1) when the nozzle channel wall is made of a material containing iron as a main component, the thickness of the nozzle channel wall is 0.2 mm or more and 2.5 mm or less; and (2) when the nozzle channel wall is made of a material containing aluminum as a main component, the thickness of the nozzle channel wall is 0.2 mm or more and 4 mm or less.

  • Publication number: 20190159013
    Abstract: A decrease is realized in network load caused by a change in selection of location registration device or an increase or decrease in the number of installations, on a circuit switching network side. A mobile communication system includes a mobile station, a packet switching station, and a plurality of location registration devices that perform location management of the mobile station. With respect to the mobile station, after one location registration device is already selected from among the plurality of location registration devices, when the mobile station performs location registration, an NRI (Network Resource Identifier) included in a TMSI (Temporary Mobile Station Identifier) is transmitted to the packet switching station. The packet switching station makes a request for location registration with respect to the one location registration device, based on the NRI.
