摘要： PURPOSE:To facilitate the highly accurate timing control to change the supply sate of a specific gas which is made to flow in accordance with the opening/ closing states of a plurality of gas pressure operating valves which respond to a plurality of solenoid valves operated time-sequentially. CONSTITUTION:A plurality of gas tubes 9a-9c are connected between the respective valve unit parts 4ao-4eo of a plurality of solenoid valves 4A-4E and the respective driving parts 8ai-8ei of a plurality of gas pressure operating valves 8A-8E to drive the respective driving parts 8ai-8ei. The respective inner capacities of the gas tubes 9a-9c are determined in accordance with the operating times of the respective gas pressure operating valves 8A-8E. Therefore, when a gas supply state is switched from the supply state of one specific gas to the supply state of another specific gas, the supply state in which both gases are mixed can be avoided, so that the timing of the changeover can be controlled with a high accuracy.

摘要： PURPOSE:To measure an external leaking amount simply with high sensitivity by measuring components of a second gas included in a first gas passing through a measuring part for measuring the external leaking amount. CONSTITUTION:A leaking amount from a leaking point 101 manufactured by an MCG joint (metallic C ring) is first measured at an He leak detector 102. An H2/Ar gas 104 is supplied to the leaking point 101 having the leaking amount already detected by the He leak detector 102. An amount of N2 and O2 components included in the H2/Ar gas 104 passing through the leaking point is measured by an AP1HS 103. When the AP1MS is used, it is preferable to mix hydrogen in the first gas because a detecting sensitivity is poor only with the Ar, and a concentration of H2 in the H2/Ar gas is desirably not smaller than 1ppm.
