摘要： PURPOSE:To shorten the term of works and to reduce the expenditure of works by providing an inward flange junction part at the whole margical part of a panel material which forms a wall face and a ceiling face, and connecting it at equal pitches by bolt fastening. CONSTITUTION:A junction part 11b equipped with an inward flange part 11a is provided at the whole margical part of a panel material 11 which forms the wall face and the ceiling face of an electromagnetically shielded room, and this junction part is butt-joined and connected at regular pitches by bolt fastening. And by putting the sizes of the junction part 11b formed in each panel material and the flange part 11a and the bolt pitches when connecting it by bolt fastening in the specified dimensions, the specified shield effect can be obtained. Hereby, each constituent member manufactured in factories in advance can be carried in the site and assembled there, and the required term of works on the site can be shortened, and also the production expenditure at large can be cut down.

摘要： PURPOSE:To apply a magnetic shield to the door of an MRI room and to easily open and close said door by forming the door into a hollow shape from a non-magnetic material and filling the hollow part of the door with a magnetic fluid or allowing said fluid to flow out of the hollow part. CONSTITUTION:A door 1 is formed into a hollow shape by connecting a non-magnetic material such as a stainless steel plate and the inflow port 3 communicating with the hollow part of the door 1 is provided to the upper part of the door 1 and the outflow port 4 communicating with the hollow part is provided to the lower part of the door 1. The magnetic fluid filling the hollow part 2 of the door 1 is received in a magnetic fluid receiving tank 5 at a position slightly separated from the door 1 and lower than the outflow port 4. The magnetic fluid receiving tank 5 communicates with the inflow port 3 by a pipeline 7 having a pump 6 on the way thereof and, further, a solenoid opening and closing valve 13 is provided in the vicinity of the outflow port of the pipeline 7. When the hollow part is filled with the magnetic fluid, the leaked magnetic field from the door 1 can be reduced. When the door 1 is opened, the magnetic fluid is allowed to flow out of the hollow part to lighten the door 1 and the door 1 can be easily opened and closed without being attracted by magnetic force because the door is formed only from the non-magnetic material.

摘要： PURPOSE:To raise the electromagnetic shielding effect of a window blind by a method in which a conductive banded sealing member to close the aperture between a window frame and a blind is provided on the position facing the window frame on the peripheral side of the blind. CONSTITUTION:Carbon brushes 24 are conductive sealing members having a given length are implanted toward the direction of a window frame 2 in both sides 10a of a blind body 10 by an electric flocking method, etc. The brushes 24 are implanted in a banded form with a given width connectedly to the mesh 14 in such a way as to enable them to contact with the window frame 2. When the blind body 10 is pulled out to cover the frame 2, the body 10 is pulled toward the direction of winding around a wind shaft 6 by the action of a spring 8 and held tensely by means of an elastic material 26. The carbon brushes 24 come into contact with the frame 2 to close the aperture between the frame 2 and the body 10. The incidence of light can thus be regulated and the electromagnetic shielding effect can also be raised.
