Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To efficiently lower the spurious radiation magnetic field by generating an offset magnetic field opposite to the strongest position of the spurious radiation magnetic field, which is generated by the leaked magnetic field from a deflection yoke. SOLUTION: An in-space magnetic field surrounded by a vertical deflecting coil 2 effectively works as a vertical deflecting magnetic field, but at the same time, this magnetic field is leaked outside so as to generate a spurious radiation magnetic field. Cancel coils 4c, 4d are arranged close to each other opposite to the strongest position of the spurious radiation magnetic field, for example, a space 23 between an opening side fringe 21 and a magnetic core 2 and connected in series or in parallel to/with a coil 2 so as to generate the magnetic field in the opposite direction.  The spurious radiation magnetic field by the leaked magnetic field from the coil 2 can be efficiently lowered by arranging the coils 4c, 4d at the strongest position of the spurious radiation magnetic field on a line in parallel with a core 3 between an opening side tip and a neck side tip of a deflection yoke 1.

Abstract: PURPOSE: To specify a medium by a method wherein two magnetic layers with different coercive forces are laminated and a density distribution of a magnetic material is formed on a low coercive force layer corresponding to a magnetic recording of a high coercive force layer to obtain a recording allowing no tampering. CONSTITUTION: A first magnetic layer 3 of 4-20μm comprising a magnetic powder of gamma Fe2 O3 or the like and a second magnetic layer 4 of 4-20μm comprising a flaky high magnetic permeability powder of permalloy or the like are formed sequentially on a base body 2 comprising a non-magnetic material such as PET. After the formation of the first magnetic layer 3, stationary information such as signal for specifying a medium is recorded magnetically and the second magnetic layer 4 is applied thereon. The second magnetic layer 4 is solidified applying an orientation magnetic field lower than the coercive force of the magnetic layer 3 to obtain a density distribution of a magnetic material corresponding to a magnetic recording of the first magnetic layer 3.  A current Ib for saturation magnetization of the second magnetic layer 4 is flowing through an erasure coil 10 to read a recording with a read coil 11. Thus, the justification of the medium is judged from a difference from an output read out by inverting the polarity of the current Ib.

Title: Control device of electric power steering device
Inventor: KAWADA HIDEAKI
IPC: B62D5/04
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To detect the ground fault and failure of a motor terminal by generation of a current of a prescribe value or more, stop the drive of the motor, and turn OFF a fail relay by turning ON the fail relay after ON of an ignition key, and turning ON the upper stage FET of an H bridge circuit with the lower stage FET being in OFF state. SOLUTION: In starting the upper stage FET 1, 2 of the driving circuit of a motor 20 are simultaneously ON, and in the ground fault of the motor 20, the ground fault is detected by generation of an overcurrent without rotating the motor in the same potential between terminals of the motor 20. Since the motor line ground fault is detected by the detecting overcurrent, an erroneous detection by the counter electromotive force of the motor 20 in returning of a handle can be avoided. When the overcurrent is detected by an overcurrent detecting means, a fail relay 41 is OFF by an overcurrent detection signal, and the drive of the driving circuit of the motor 20 is stopped, or FET 1-4 are OFF. Thus, a burning accident of the motor 20 by overcurrent can be prevented.

Filed: 1990-11-24
Abstract: PURPOSE: To obtain a toner low level detection display device which is easily attached and actuated by providing an arm member extended downward and a magnetic means connected with the arm member. CONSTITUTION: An arm assembly 84 is vertical and is surrounded by toner 85 first. A magnet 98 is matched with an electromagnetic actuation type switch 102 in a horizontal direction. When a cartridge is rotated counterclockwise, the toner 85 is moved to an upper end. The arm 84 is rotated by 15 deg. to 30 deg. from a vertical position. A switch 102 is off because it is not influenced by the magnet 98. At the time of stopping rotation, the arm is not restored to the vertical position due to the viscous resistance of the toner. When a toner level becomes low because of consecutive actuation, the arm approaches to the vertical position and the magnet 98 closes the switch 102. Then, the device 100 generates a toner low level display signal, for example, so as to actuate a visual display unit and generates an audible signal so as to actuate an acoustic device.
