摘要： PROBLEM TO BE SOLVED: To eliminate a gap between a lower end part of an electromagnetic wave shielding curtain and a floor of an electromagnetic shielding structure by eliminating the harmful influence of alignment mismatch, caused between the lower end part of the electromagnetic wave shielding curtain and the floor, and secular change, etc. of a member. SOLUTION: By a lower shield gap eliminating means constituted by an electromagnet Mg(i) provided below a curtain contact member 22 on a floor side, a floor contact member 11 fixed to the lower end part of the electromagnetic wave shielding curtain 9 is magnetically attracted and pulled, to make the floor contact member 11 stick fast to the curtain contact member 22. Thereby the harmful influence of mismatch of alignment, caused between the curtain contact member 22 and the floor contact member 11, and warping and deflection, etc. caused by secular change, etc. of the floor contact member is suppressed, and the lower end part of the electromagnetic wave shielding curtain 9 is electrically connected to the curtain contact member 22 on the floor side without fail, to acquire a short circuit resistance value required for electromagnetic shielding.

摘要： PROBLEM TO BE SOLVED: To obtain an electromagnetic wave shielding door that allows an electromagnetic wave shield member to securely adhere to a floor surface for effectively shielding an electromagnetic wave. SOLUTION: A slit 5 with a length equal to the entire width of a door body 4 is formed on the lower end face of an electromagnetic shielding door 1, and an electromagnetic shielding member 6 with a length equal to the entire width of the door body 4 is provided inside. An electromagnetic wave shielding member projection mechanism 7 linked to the operation of an open and close handle 11 is provided, and both ends of the electromagnetic wave shielding member 6 are pressed for descending, thus allowing the electromagnetic wave shielding member 6 to securely adhere onto a floor surface over the entire length.

摘要： PROBLEM TO BE SOLVED: To efficiently operate both a radiographic image diagnosis device and an MRI device by solving the problem that when a radiographic image diagnosis device and the MRI device are disposed in a single examination room, and a power supply of the radiographic image diagnosis device is turned on to efficiently operate both devices to be on standby for photographing, electromagnetic wave noise is generated from the radiographic image diagnosis device to exert a bad influence upon the operation of the MRI device.
SOLUTION: An opening and closing electromagnetic wave shield mechanism 50 is provided in a boundary between a radiographic image diagnosis device installation space 31 and an MRI device installation space in the examination room 10. The opening and closing electromagnetic wave shield mechanism 50 is disposed between one wall surface and the other wall surface of the examination room, and a shield curtain 51 is opened and closed by an electric motor. When the shield curtain 51 is closed, the electromagnetic wave noise generated from the radiographic image diagnosis device whose power supply is in the on state is shielded to the MRI device installation space 32.

摘要： PROBLEM TO BE SOLVED: To offer an electromagnetic wave shielding unit for air conditioning port, having enhanced shielding performance with respect to electromagnetic waves at a low price. SOLUTION: In a frame 14 having sidewalls 16, many conductive metal plates are placed in parallel, allowing a spacing, and both ends of each conductive metal plate are electrically connected to the inside surfaces of the sidewalls 16 so as to make many cells 21, which function as waveguides for cutting off, in the frame 14. As the conductive metal plates are placed in parallel without crossing each other, they have no needless cuts. Each complete cell 21, which functions as a waveguide for cut off, is composed of two adjacent conductive metal plates so as to ensure enhanced shielding performance. In addition, there is no need for processing of cuts, etc., and no intersections of conductive metal plates which facilitate the processing and assembly. This advantage and dispersing with post-processing for ensuring continuity reduce manufacturing costs.
