摘要:
Disclosed is a magentic resonance imaging apparatus which comprises a transmission probe head, a reception probe head, and inclined magnetic field coil means. The transmission probe head applies a high-frequency magnetic field to a subject, while the reception probe head receives magnetic resonance signals from the subject. The inclined magnetic field coil means generates and applies an inclined magnetic field to the subject. If the inclined magnetic field is applied to the subject, the magnetic resonance signals detected by the reception probe head are provided with generative position information. An electromagnetic coupling prevention member is interposed between the coil means and the transmission and reception probe heads. The prevention member includes a plurality of high-conductivity portions and a plurality of electrically discontinuous portions electrically separating the high-conductivity portions from one another.

In a apparatus for examining an object by nuclear magnetic resonance to produce images of cross-sectional slices of the object, it necessarily requires to have "a wait time" so as to repeat the applications of the RF pulses toward a plurality of such slices during one examination cycle. A plurality of coil pairs is arranged along the longitudinal axis of the object, and each pair is selectively energized so as to apply to the plurality of slices one of a plurality of gradient fields in conjunction with the steady magnetic field. A plurality of nuclear magnetic resonance signals may be obtained from a plurality of slices during one examination cycle.

An electric dynamometer which includes a rotor mounted for rotation on a shaft and a stator surrounding the rotor, the stator including a yoke surrounding the rotor in radially spaced relation therewith, and a loss drum disposed between the yoke and the rotor so as to be rotatable 360.degree. about the rotor. An electric motor is coupled through its rotor to the loss drum so as to rotate the loss drum therewith. A stator of the electric motor is fixed to the yoke, and the yoke and stator of the motor are supported for rotation about the respective rotors. A torque detector is fixed to the stator of the motor so as to measure the combined torque exterted on the yoke and the stator of the motor about the rotors.

A device for correcting the torque detected by an electric dynamometer, which is capable of very accurately correcting loss torques of the operation-type dynamometer based upon a simply constructed mechanism. Among many loss torques involved in the operation-type electric dynamometer, the windage-loss torque which plays a major role is accurately corrected as a function of the atmospheric pressure, atmospheric temperature and rotation speed, thereby to very accurately correct the torque.

A method is disclosed for automatically shifting the sub-transmission of a vehicle which is also equipped with a manual transmission operated by hand by the driver. When the driver shifts by hand to a certain gearing ratio, a vehicle operating parameter is detected, and, on the basis of this detected value, the procedure for shifting the sub-transmission is modified. Shift control of the sub-transmission is performed in accordance with this modified sub-transmission shift procedure, for a first time period, while the manual transmission remains in this gearing ratio, and subsequently for a second time period shift control of the sub-transmission is performed so as to maximize fuel economy, while the manual transmission remains in this gearing ratio.
