In a refrigeration apparatus having a plurality of compressors, which are connected in parallel and are operated, in an outdoor unit, a compressor (inverter compressor) is started surely after the stoppage of operation. In the refrigeration apparatus in which the outdoor unit 100 includes two compressors of a first compressor 110 and a second compressor 120, which are connected in parallel with each other; an oil separator 111, 121 is provided on the discharge side of each of the compressors; a first oil separator 111 on the first compressor side is connected to a suction pipe 164 of the second compressor via first oil return piping 114 including a pressure reducing means 115, and a second oil separator 121 on the second compressor side is connected to a suction pipe 163 of the first compressor via second oil return piping 124 including a pressure reducing means 125; and the first compressor is an inverter compressor, and the second compressor is a constant-speed compressor, a solenoid valve 116 is connected in parallel with the pressure reducing means 115 of the first oil return piping 114, and before the restart of the first compressor (inverter compressor) 110, the solenoid valve 116 is turned on to cause the discharge side and the suction side to be approximately equalized.

摘要:
A packet interval (a time difference between sequentially received packets) in a certain previous time is calculated and a cumulative distribution function of the calculated packet interval is obtained. Meanwhile, a function value-corresponding to-flow end that is a boundary value of the cumulative distribution function to be considered as a flow end (timeout) in the range of a cumulative distribution function value is stored. From the cumulative distribution function obtained as described above, a value of a packet interval mapped to a cumulative distribution function value that matches the function value-corresponding to-flow end is set as a threshold. That is, the threshold is dynamically set based on a previous packet interval. Therefore, a packet stop period from a last packet reception time to a current time is measured, and it is detected as a flow timeout at a timing when the measured value is equal to or greater than the threshold.

A wireless base station (1) includes a wakeup device (13) and a main device (14). When the main device (14) is in a sleep mode, the wakeup device (13) is connected to the antenna (11). Then, when the wakeup device (13) receives a wakeup signal for activating the wireless base station (1) from a terminal device assigned to the wireless base station (1) in a communication band used for wireless communication with the terminal device and when the information for identifying a wireless base station to be activated contained in the received wakeup signal is identical with the identification information of the wireless base station (1), the wakeup device (13) outputs a driving signal to the main device (14). The main device (14) transitions from the sleep mode to an operating mode in response to the driving signal from the wakeup device (13).
