    摘要： An MRI apparatus having a configuration that reduces vibration of a static magnetic field generating source is provided. A closed vessel 2 of the static magnetic field generating source is provided with a rigid structure 4 for preventing transmission of vibration generated from a gradient magnetic field generating part 21 to other members via the closed vessel 2. The rigid structure 4 uses, for example, a connecting part 4 that connects a face 25 on the imaging space side and a face 26 confronting it. The rigidity of the closed vessel is thereby increased, and therefore vibration transmitted from the gradient magnetic field generating part can be reduced. The connecting part can have a through-hole structure, and in such a case, internal space of through-hole can be used for drawing cables.

    摘要： A magnet device provided with a shield current carrying means in which two sets of magneto-static field generating sources for generating magnetic fields directed towards a first direction are disposed facing each other across a finite region and at least one set of the magneto-static field generating sources are disclosed on at least two almost concentric circles. A first plane includes a first axis, a second axis and a first point. The first point is a point of insertion between the first axis parallel to the first direction and passing almost through the center of the shield current carrying means. The second axis crosses at right angles to the first axis and is spaced almost equal distance from the two sets of the generating sources. The alternately arranged positive and negative current carrying directions of the shield current carrying means are set in the order of increasing value of θn.

    摘要： An electronic device includes a front panel made of resin. The front panel is disposed on the front side of an organic electroluminescent display panel and functions as the front surface of the electronic device; and an adhesive agent layer formed between the organic electroluminescent display panel and the front panel. The organic electroluminescent display panel is fixed to the front panel via the adhesive agent layer. This structure is able to reduce a load applied to the organic electroluminescent display panel and ensure shock resistance for the organic electroluminescent display panel.
