Abstract:
A shutter moves along a surface of a partition wall provided between two spaces different in pressure, which faces the space higher in pressure, to open and close an aperture formed on the partition wall with an amount of force smaller than conventional shutters require. The shutter includes: a plate-shaped first member arranged in a manner of moving along a surface of the partition wall, which faces one of the two spaces higher in pressure, to open and close the aperture, the first member being provided, in a region which corresponds to the aperture, with a small aperture having an area smaller than the area of the aperture, and a plate-shaped second member arranged in a manner of moving along a surface of the first member, which faces the space higher in pressure, to open and close the small aperture.

Claim (Index 1):
A shutter for use in opening and closing an aperture in a partition wall provided between two spaces different in pressure, the shutter comprising:\n a) a first member arranged in a manner of moving along a surface of the partition wall, which faces one of the two spaces higher in pressure, to open and close the aperture, the first member being provided, at a position which corresponds to the aperture, with a small aperture having an area smaller than an area of the aperture: b) a second member arranged in a manner of moving along a surface of the first member, which faces the space higher in pressure, to open and close the small aperture; c) a driving section for moving the first member and the second member; and d) a drive control section for controlling the driving section so that the shutter passes through an intermediately-opened state with the aperture closed and the small aperture opened when the shutter is shifted from a full-open state with the aperture and the small aperture both opened to a full-closed state with the aperture and the small aperture both, as well as from the full-closed state to the full-open state.
