Abstract: PROBLEM TO BE SOLVED: To increase signal level precision of a signal for testing which is to be transmitted to a terminal to be measured. SOLUTION: In a state of a signal being outputted from a signal generator 2 to a path 18 via an attenuator 3, the respective signal levels in an output end 14 of the path to a terminal 9 to be measured are measured, in the case that an attenuation setting amount D of the attenuator is changed sequentially, and calibration values DA to the respective attenuation setting amounts are obtained. The respective signal levels in an output end of the path are measured, when a frequency H of the signal outputted from the signal generator to the path is changed sequentially, and calibration values DF to the respective frequency values are obtained.

IPC: F16K15/04
Filed: 2001-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a check valve which eliminates the need for a coil spring and can increase a flow rate. SOLUTION: The check valve includes a valve chest 12; a first conduit 13 and a second conduit 14 opened at opposing positions of the valve chest 12; valve seats 13a and 14a formed in valve chest side ends of the first and second conduits; a discharge conduit 15 opened in an intermediate portion between the two valve seats; and a valve element 16 movably provided between the two valve seats in the valve chest.
