  • Patent number: 11964533
    Abstract: In a fastener structure for a vehicle, a height adjustment spacer is interposed between first and second vehicle body frames fixed with a bolt and a nut. The nut has a first insertion hole through which a bolt is screwed, and is fixed to a surface of the first vehicle body frame. The height adjustment spacer has a second insertion hole through which the bolt is inserted, and is disposed in contact with another surface of the first vehicle body frame. The bolt is inserted through an attachment hole of the second vehicle body frame, the second insertion hole, an attachment hole of the first vehicle body frame, and the first insertion hole. On a contact surface between the height adjustment spacer and the first vehicle body frame, a protrusion and a recess are provided to surround an entirety of the second insertion hole, the second insertion hole respectively.

  • Publication number: 20240022901
    Abstract: The present disclosure is directed to providing a gateway device that can properly page a communication terminal managed by a control device even if the control device loses information on the communication terminal when the control device recovers from a failure that has occurred therein. A gateway device (10) according to the present disclosure includes a storage unit (11) configured to store temporarily allocated identification information temporarily allocated to a communication terminal and an eDRX parameter associated with the communication terminal, and a transceiver (12) configured to, in a case in which downlink data destined for a communication terminal managed by a mobility management device (20) is received after a failure has occurred in the mobility management device (20), transmit a notification message with the temporarily allocated identification information and the eDRX parameter set therein to the mobility management device (20) or another mobility management device (21).

  • Publication number: 20230224779
    Abstract: A radio terminal (1) determines that the radio terminal (1) is approaching a first station (5), receives from a center server (4) a cell identifier of a first cell corresponding to an entrance gate function (53) of the first station (5), and transmit a message containing the cell identifier to a cellular communication network. The message causes the network to add the first cell (54) as a secondary cell in dual connectivity for the radio terminal (1), enabling the radio terminal (1) to communicate with the entrance gate function (53) via a user plane path including a radio connection of the first cell (54). The radio terminal (1) then communicates with the entrance gate function (53) via the user plane path. This contributes, for example, to reducing latency required to transmit or receive user data in a narrow coverage cell when a radio terminal receives a signal from that cell.

  • Patent number: 11509007
    Abstract: A refrigeration cycle cools a battery. A controller controls a refrigerant flow rate flowing through a battery cooling system so as to adjust a temperature of the battery. The controller adjusts the refrigerant flow rate flowing in the battery cooling system so that the oil retained in the battery cooling system is flushed toward the compressor. The battery cooling system has a plurality of parallel systems. Electric expansion valves as flow adjusting valves are controlled so as to intermittently provide an oil-back operation. In the oil-back operation, the flow rate of the refrigerant flowing through a part among the plurality of parallel systems is increased more than a flow rate of the refrigerant flowed by a temperature control unit.

  • Publication number: 20220295363
    Abstract: A Policy Control Function (PCF) apparatus (34) receives information from a Network Exposure Function (NEF) apparatus (35) or an Application Function (AF) apparatus (41) and modifies based on the information a policy including an Index to RAT/Frequency Selection Priority (RFSP index). This can, for example, contribute to enabling a radio communication network to provide a User Equipment (UE) with a user plane path containing a radio connection in a specific cell based on a request from an AF.

  • Publication number: 20220264679
    Abstract: A User Equipment (UE) (3) includes, in a Non-Access Stratum (NAS) message requesting establishment or modification of a protocol data unit (PDU) session, one or both of a first identifier representing a candidate secondary cell (12) for dual connectivity and a second identifier representing a frequency band in which the candidate secondary cell operates. The UE (3) sends the NAS message to a core network (30) via a radio access network (10). This can, for example, allow a radio communication network to provide a UE with a user plane path that includes a radio connection in a specific secondary cell of dual connectivity based on a request from the UE or an application function.

  • Patent number: 11001936
    Abstract: A rotational surface treating device with a high treatment efficiency that allows a treatment liquid to be discharged in a short time is provided. When a treatment bath 2 is rotated, parts 20 contact an electrode 50 to be electroplated. In this event, a plating liquid 16 is used as circulated by a pump P. The plating liquid 16 is discharged to the outside through a gap in a side wall 80 for replacement of the plating liquid 16 or the like. During discharge, the plating liquid 16 is not circulated by the pump P. The gap 8 which is formed in the side wall 80 is formed to be smaller than the minimum dimension of the parts 20 on the inner side. The gap 8 is formed to be wider toward the outer side. Thus, water is discharged immediately.
