摘要： A control device of a magnetic resonance imaging (MRI) apparatus includes a condition setting unit and a judging unit. The condition setting unit sets an imaging sequence to be performed by the MRI apparatus based on set conditions of the set imaging sequence. The judging unit then (a) calculates a value of electric current that would need to be supplied to a gradient magnetic field coil of the MRI apparatus to perform that set imaging sequence based on the set conditions of the set imaging sequence, (b) calculates a value of voltage that would need to be applied to the gradient magnetic field coil based on a mutual inductance of the gradient magnetic field to cause electric current flowing to the gradient magnetic field coil to equal to the value of the calculated electric current, and (c) judges whether the set imaging sequence is practicable or not based on the calculated value of voltage.

摘要： A steering control apparatus has a variable gear ratio device and a power steering device. If abnormality arises in the VGRS device, an EPS motor is controlled based on a steering wheel angle and a speed increase ratio. Thus, vehicle wheels are controlled appropriately when abnormality arises in the VGRS device. Steered angle of the vehicle wheels relative to the steering wheel angle is not changed between before and after occurrence of abnormality in the VGRS device. As a result, movement of a vehicle does not deviate from the steering wheel angle and feeling of discomfort in steering a vehicle can be reduced.

摘要： In a steering control apparatus, a worm gear is configured to have a lead angle for a self-lock operation, by which a worm wheel is allowed to rotate by rotation of a worm but the worm is not allowed to rotate by rotation of the worm wheel. Thus, a lock mechanism need not be provided separately from a gear mechanism and the apparatus is reduced in entire size. A VGRS control part checks whether the worm gear has a self-lock failure, which disables the self-lock operation. If the worm gear has the self-lock failure, idling suppression processing is performed to suppress idling of a steering wheel. Thus, even when the self-lock failure arises, the steering wheel is suppressed from idling.

摘要： A steering control apparatus acquires vibration torque, which is generated by vibration of a gear mechanism when a steering wheel is operated at a steering angle. By setting the acquired vibration torque as a torque difference, an EPS motor current command value is corrected based on the torque difference thereby to calculate a corrected EPS motor current command value. Rattling and vibration caused in the gear mechanism are suppressed from being transferred to the steering wheel through an input shaft so that a driver is released from uncomfortable feeling.
