The seat type seeker which is suited in order to execute method and the said method of driving the seat type leakage seeker

摘要

(57) Abstract This invention has two seats which Hari facilities are done respectively in one frame, being the method of driving the seat type leakage seeker where the test room is restricted when the suffering body has been inserted by the aforementioned seat, has two vacuum blowers, exhaust it does the test room first, it regards those of the type which is changed to rear leakage inquiry driving of this exhaust driving. In the peripheral air, in order to evade the disturbance of the leakage inquiry with the helium density which fluctuates, helium density of the peripheral air is measured before the starting the leakage inquiry process, it is proposed that the result is considered at the time of the leakage measurement which follows.
