摘要:
In a light source, a heat sink is in contact with a side-on type discharge tube 110. The heat sink is in contact with a peripheral region 110ws around an exit window 101ww of the discharge tube 110. The heat sink consists of a spring member 101sp kept in direct contact with the peripheral region 101ws, and a radiating block 101bl which connects the spring member 101sp to a radiator box 101bx. Since materials made by sputtering or the like of electrodes in the discharge tube 110 mostly attach to the peripheral region 101ws of side wall 101w, it is feasible to decrease the amount of materials attaching to the exit window 101ww and, in turn, lengthen the lifetime of the discharge tube. Another light source may be constructed in structure in which the heat sink is in contact with a head-on type discharge tube or in structure in which light is outputted from a projecting portion.

A mobile communication system includes a first radio control device that manages a first cell, a second radio control device that manages a second cell, and a third radio control device. The second cell is set as a handover destination cell of the first cell. The third radio control device manages the second cell as a redundant configuration of the second radio control device. The third radio control device notifies the first radio control device of the third radio control device managing the second cell as the redundant configuration of the second radio control device. The first radio control device sets so that the third radio control device manages the second cell as the redundant configuration of the second radio control device.

摘要:
A mobile communication system having a first communication system and a second communication system forwards forwarding data from the first communication system to the second communication system when switching from the first communication system to the second communication system is determined, the forwarding data being a data that the first communication system has already received from a core network device. A network device transmitting direct data to a mobile communication terminal via the second communication system is configured to count the number of switching times that the switching from the first communication system to the second communication system has been determined, for every user. The network device is configured to count the number of successful reception times that information identifying a user has been received via a forwarding path of the forwarding data, for every user. The network device is configured to judge whether the forwarding path of the forwarding data is normal or not on the basis of a ratio between the number of switching times and the number of successful reception times.
摘要:
A second communication system starts transmission of direct data received from a core network apparatus without waiting to receive an end marker when the end marker indicating the last forwarding data forwarded from the first communication system is not received within an end marker waiting period.

摘要:
A radio network controller activates a signal transmission suppression timer to suppress transmission of a congestion signal, when a new radio base station is added as a radio base station with which the radio terminal is to communicate, and suspends the transmission of the congestion signal to the radio base stations until the signal transmission suppression timer expires.

The radio network controller 30 includes a block error detection unit 31 configured to receive a data block from the base station 20 and to detect a block error, and a target SIR calculation unit 32 configured to calculate a target SIR based on the detected block error rate.The target calculation unit 32 sets the first time section, which indicates a time section from a detection of the block error to the notification of the target SIR is to the base station 20 when the block error is detected, shorter than a second time section, which indicates a time section from the detection of the block error to the notification of the target SIR to the base station 20 when the block error is not detected.
摘要:
A headrest that facilitates the assembly of a structural member for absorbing impact, and a method for producing the same. The method for manufacturing the headrest having surface material, headrest stay, seal sealing an opening at the bottom of headrest, plate-like impact-absorbing member, one end of which is connected to seal, and foamed body in headrest includes a step of inserting headrest stay in insertion holes and of seal and assembling it, a step of inserting headrest stay and impact-absorbing member through the opening, a step of inserting a circumferential portion of the opening of surface material into seal, a step of injecting a foaming material through injection hole of seal and foaming it, and a step of forming a foamed body by curing the injected foaming material. The opening is sealed when the foaming material impregnates and cures at the circumferential portion of the opening.
