  • Publication number: 20160033948
    Abstract: A plurality of pieces of candidate information capable of serving as device identification information are divided into a plurality of groups in advance. Each of the plurality of groups is provided with group identification information. A master control unit sequentially outputs pieces of group identification information to a signal line. When group identification information of a belonging group of a device flows through the signal line, a control unit of the device outputs device identification information, stored by the control unit, to the signal line. In this case, a control unit outputs the device identification information after the group identification information is received and then a standby time has elapsed. The standby time is set on the basis of the order of the device identification information of the device within a belonging group. The master control unit provides an address to the received device identification information.

  • Patent number: 6731675
    Abstract: A receiving device is provided with a DLL circuit of a reduced scale. An inverse spreading processing to ensure the synchronism with a received signal and a processing to inversely spread original data in the received signal are performed by a time-sharing operation using one inverse spreading circuit and one integrator. During a period in which synchronous data for detecting a slot duration included in the received signal is received, the synchronous data is alternately inversely spread by an early code and a late code and sample-hold circuits alternately sample and hold the integrated output. Further, based on the difference (error signal) between sample-hold signals, the early code, the late code and a reference code outputted from a code sequence generator are synchronized with the received signal.

  • Patent number: 6310582
    Abstract: When communication is performed simultaneously with two moving bodies such as a satellite, an antenna construction in which a plurality of antennas do not become an obstacle to each other's communication and the direction (the azimuth angle and the elevation angle) adjusting mechanism thereof can be realized with a simple construction. The two antennas have another movable portion (a rotation mechanism with respect to the axis) independently, while sharing the direction adjusting mechanism for the azimuth angle and the elevation angle. The rotation axis of the rotation mechanism of each antenna faces the same direction on the same plane, and each rotation mechanism is separately arranged in an area defined by a plane obtained by extending the axis of the azimuth angle adjusting mechanism toward the axial direction of the elevation angle adjusting mechanism.
