Patent JP-S61128798-A (JP)
Title: Excitation controller
Inventor: URATA SEISHI
IPC: H02P9/10
Filed: 1984-11-28
Abstract: PURPOSE:To prevent an overvoltage from applying to a field winding and a field circuit device by composing a bypass circuit when the reverse voltage of the winding becomes the prescribed value or higher. CONSTITUTION:A current is flowed as a solid line before a field switch 5 is opened, a positive voltage is generated at field P-pole and a negative voltage is generated at N-pole. Negative voltage is generated at the P-pole and positive voltage is generated at the N-pole at switch opening time. At this time, when a voltage V0 between the gate and the cathode of a thyristor 11 for a bypass circuit becomes the specified value or larger, a signal is applied to the gate of a thyristor 11 by the voltage divided by resistors 15, 16 to conduct the thyristor 11. As a result, a reverse voltage generated between the field P- and N-poles when the switch 6 is opened is suppressed to the voltage of the product of the current flowed to the thyristor 11 and the resistance.

Title: Magnetic head device
Inventor: FUJITAKE TOSHIYUKI
IPC: G11B5/48
Filed: 1983-12-27
Abstract: PURPOSE:To simplify manufacturing processes by providing a slope part to a main body side face of a magnetic head of a magnetic disc device to ensure loading/ejection of a medium without provision of a mechanism lifting a jacket. CONSTITUTION:In loading the medium 18 covered on the jacket 17 in the direction of arrow 40, the jacket 17 is set to a prescribed position after contact with a head slider 30. Since the head slider 30 has a slope 31a to the loading direction of the medium 18, it is prevented that the tip of the jacket 17 is latched to the slider 30. In ejecting the jacket 17 (in the arrow 41), since the slider 30 has a slope 31b in the ejecting direction of the medium 18, it is prevented that the end 20 of a head window part 19 of the jacket 17 is latched to the slider 30. Thus, the medium 18 is loaded/ejected surely.

Title: Magnetic resonance image pickup device and method of designing gradient coil for magnetic resonance image pickup device
Inventor: MAIKERU EI MORITSUCHI
IPC: G01R33/34
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a nuclear magnetic resonance camera instrument capable of facilitating the equipment and constitution of a gradient coil and by which the access to patient body is promoted in the examination area and pictures are improved. SOLUTION: The nuclear magnetic resonance camera instrument includes a superconducting magnet 10 that generates a temporally constant magnetic field in a bore 12. Both of the bore and the superconducting magnet have lengths which are relatively short compared to their respective diameters, for example, ratio of length to diameter is smaller than 1.5:1, and preferably 1:1. The gradient coil assembly 30 of the instrument is disposed around the bore and it generates a gradient magnetic field across the bore. With this relatively short bore magnet, in the region in which the gradient magnetic field coil is disposed, the main magnetic field suffers nonuniformities including radial magnetic field components.  While current pulses are fed through the windings of a primary gradient coil 32 and a secondary gradient coil 34 of the gradient coil assembly, the currents interact in an unbalanced manner with the nonuniformities and the radial components of the temporally constant magnetic field, causing a net force in axial and/or transverse direction.
