Title: Navigation apparatus equipped with gyro sensor
Inventor: KAMIMURA MASATSUGU
IPC: G01C21/00
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a navigation apparatus by which an azimuth error due to the offset correction of a gyro sensor is suppressed. SOLUTION: An offset correction means 11 corrects an offset in the output of a gyro sensor 1. An offset correction value is obtained under a definite condition such as a condition under which a vehicle is stopped, and a preliminary correction value is stored in a storage means 12. The time elapsed since a preliminary offset correction is clocked by a clocking means 13. When the offset correction means 11 performs a next offset correction, the difference between a new offset correction value and the offset correction value which is stored in the storage means 12 is computed by an azimuth correction means 14, it is multiplied by the time elaped which is clocked by the clocking means 13, and an azimuth which is displayed by the gyro sensor 1 is corrected according to a multiplied result.  Since the azimuth is corrected together with the offset correction, it is possible to prevent an azimuth error due to the offset correction from being accumulated.

Title: Magnetic head
Inventor: MARUTA YUZO
IPC: G11B5/187
Filed: 1987-12-11
Abstract: PURPOSE:To prevent a slider from being brought into contact with a magnetic medium at the time of starting and stopping the rotation of the magnetic medium and while it stops by providing a superconducting members in a magnetic head. CONSTITUTION:The superconducting members 7 are provided on both sides of a magnetic medium confronting surface in the slider 4 of the magnetic head 6. When the magnetic medium 5 stops, the slider 4 repulses with a magnetic flux G which occurs from the magnetic medium 5 to a magnetic direction (d) and it floats from the magnetic medium 5 by the Meissner effect of the superconducting member 7. When the magnetic medium 5 rotates, buoyancy by the viscous film of air, which occurs on the surface of the magnetic medium, is furthermore added. Since buoyancy by the viscous film of air is disappeared and buoyancy by the Meissner effect of the superconducting member 7 exists when the magnetic medium 5 stops, the magnetic head 6 is in a state that it floats from the magnetic medium 5 as it is. Thus, the magnetic head in which the slider is not brought into contact with the magnetic medium when the rotation of the magnetic medium starts, stops and while it stops can be obtained.
