  • Publication number: 20230079806
    Abstract: An identifier setting system disclosed herein includes a plurality of control devices, a communication line, and an activation line. In a case where an identifier setting section of a control device, which is one of the plurality of control devices, determines that an identifier of the control device is not set, a monitoring section acquires identifiers output from the plurality of control devices, and an activation control section controls the activation line so as to stop another control device, which does not output the identifier. The identifier setting section sets an identifier different from the identifiers acquired by the monitoring section as the identifier of the control device. The activation control section controls the activation line so as to activate the other control device, which does not output the identifier.

  • Patent number: 11594388
    Abstract: A control unit includes: an input portion that receives the positional information of a vehicle; a calculation unit that generates a control signal for controlling an electromagnetic relay; and an output portion that outputs the control signal to the electromagnetic relay. The calculation unit determines whether a location region of the electromagnetic relay is a relay-freeze region, the location region being identified by the positional information of the vehicle, and, when the location region of the electromagnetic relay is a relay-freeze region, performs a freeze inhibiting process for preventing the electromagnetic relay from being frozen or defrosting the electromagnetic relay by opening and closing the electromagnetic relay and causing the electromagnetic relay to vibrate.

  • Patent number: 8125863
    Abstract: An information recording/reproducing apparatus including an optical pickup unit for generating an RF signal performs signal processing to acquire, at a restart of recording after a halt of recording, a data ID to be used as a reference for specifying a recording restart position in the recording medium based on the RF signal. The signal processing includes reproduced signal generation processing to generate a reproduced signal based on the RF signal, and data ID acquisition determination processing to determine, at the restart of recording after the halt of recording, whether or not the data ID has been properly acquired, based on the reproduced signal. If it is determined in the data ID acquisition determination step that the data ID has not been properly acquired, a reproduction parameter to be used for generating the reproduced signal in the reproduced signal generation step is adjusted.

  • Patent number: 7481466
    Abstract: A coupling apparatus includes a pair of cylindrical coupling main bodies which are concentrically and oppositely arranged to each other and which have the same structure as to each other, liners which are accommodated in the coupling main bodies respectively, and a release preventing structure which can selectively resist a rotational force applied to the coupling main bodies coupled with each other, so that a coupling of the coupling main bodies is maintained.

  • Publication number: 20060095637
    Abstract: A bus control device for controlling a bus system composed of a first bus and a second bus connected via a bridge unit. In the bus control device, a first arbitration unit obtains bandwidth information that specifies required bandwidth for data transfer between a first device connected to the first bus and a second device connected to the second bus, and gives a usage right for the first bus to the first device for a first allocated period set in accordance with the obtained bandwidth information; a second arbitration unit arbitrates a usage right for the second bus; and a notification unit notifies the bandwidth information from the first arbitration unit to the second arbitration unit. The second arbitration unit gives the usage right for the second bus to the bridge unit for a second allocated period set in accordance with the bandwidth information notified by the first arbitration unit.
