Abstract: A valve body has an inflow passage for a working fluid, an outflow passage for the working fluid, and a pressure relief passage, which connects the inflow passage and the outflow passage by bypassing a normally close valve seat. A pressure relief valve is located in the pressure relief passage. The pressure relief valve closes the pressure relief passage, if a pressure of the working fluid in the outflow passage is lower than, is equal to, and is higher by a pressure difference less than a predetermined relief pressure than a pressure of the working fluid in the inflow passage. The pressure relief valve opens the pressure relief passage, if the pressure of the working fluid in the outflow passage is higher by a pressure difference equal to or higher than the relief pressure than a pressure of the working fluid in the inflow passage.

Abstract: In a time synchronization system, a network controller sets transmission distance information on a transmission distance through which an optical signal is transmitted between transmission and receiving servers via a queueless network to a receiving server, based on network topology information. The transmitting server transmits a transmitting side current time synchronized with a reference time to the receiving server 12 via the queueless network. The receiving server calculates a transmission delay time between the transmission and receiving servers by dividing the transmission distance, which is based on the set transmission distance information, by light speed in the queueless network. A receiving side current time is calculated by adding the transmission delay time to the transmitting side current time.
