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.

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： Motor-control device for an image forming apparatus includes a motor, an encoder, a microcomputer, and a driving circuit. The encoder generates a pulse signal in response to rotation of the motor. The microcomputer includes a CPU, a RAM and a ROM. The CPU detects actual rotational speed of the motor based upon the pulse signal generated by the encoder. The CPU cyclically provides a driving signal by comparing the actual rotational speed with a predetermined target rotational speed of the motor. An operating cycle is proportional to a cycle of the pulse signal generated by the encoder. The driving circuit drives the motor based upon the driving signal provided by the CPU. The CPU determines the operating cycle based upon the predetermined target rotational speed. The CPU also determines whether the motor condition is normal or abnormal by comparing the driving signal with a predetermined reference driving signal.
