  • Publication number: 20240120663
    Abstract: An antenna module includes an antenna substrate and a feed circuit. The antenna substrate has an upper surface and a lower surface, and a radiating element having a flat plate shape is arranged in the antenna substrate. The feed circuit 105 is mounted on the lower surface of the antenna substrate and supplies a radio frequency signal to the radiating element. The antenna substrate includes a dielectric substrate on which the radiating element is arranged, a ground electrode, a feed wiring, and carbides. The ground electrode is arranged between the radiating element and the lower surface in the dielectric substrate. The feed wiring transmits the radio frequency signal supplied from the feed circuit to the radiating element. The carbides are disposed on at least a part of a side surface connecting the upper surface and the lower surface in the dielectric substrate.

  • Patent number: 10125355
    Abstract: By combination of hydrophobic chromatography and strongly basic anion-exchange chromatography, a novel, highly hydrophobic ?-glucosidase was successfully identified from Acremonium cellulolyticus. Further, a gene corresponding to the identified ?-glucosidase was isolated. When multiple modifications were introduced into the base sequence of the gene, the gene was successfully expressed in Trichoderma viride at a high level, and the expression product successfully exhibited a high ?-glucosidase activity.

  • Publication number: 20120058780
    Abstract: A communications system and a communications method that enable to collect location information without imposing a load on the network. In an RNC of a communications system, when a communication controlling module performs communication connection processing to a mobile station among a plurality of mobile stations, a positioning module measures the location of the mobile station and the communication controlling module transmits location information of the mobile station to an exchange when communication is connected with the mobile station. In the exchange, a communication controlling module receives the location information transmitted from the RNC and a storage module stores the received location information. Then, in response to a request from a management center, the exchange transmits the location information stored in the storage module.

  • Publication number: 20110294192
    Abstract: A fusion collagenase in which an affinity tag is added to the carboxyl terminal of a collagenase was expressed as a recombinant protein. It was found that a collagenase having a collagen-binding domain can be selectively collected by purifying the obtained fusion collagenase by affinity chromatography.
