Abstract: PURPOSE:To inform the user of the arrival of replacing time of O2 sensor as required by deciding the degree of deterioration on the basis of the difference of time elapsed untill the output voltage of O2 sensor will each to such level as it is decided to be activated. CONSTITUTION:An output signal from an O2 sensor 1 is fed through an amplifier 2 to an A/D converter 3 where it is converted into an input signal for a computer 4. The time to be elapsed until the output voltage of O2 sensor 1 will reach to such level as it is decided to be activated is measured and compared with the time required prior to deterioration while stored in a backup memory of the computer 4 thus to decide the degree of deterioration. When O2 sensor 1 is under activated condition, the average output voltage is compared with any one value of rich or lean electromotive force, or any one of the times required for transiting from lean to rich or from rich to lean is employed to decide the degradation. Upon decision of deteriorated condition, it is NG displayed.

Title: Impact resistant mechanism for suspension supporting magnetic head slider and magnetic disk device using such mechanism
Inventor: KAJITANI KOJI
IPC: G11B21/21
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a disk device by embracing a restraining bar in a non-contact state in a restraining arm which restrains the movement of a restraining bar provided in a load beam, making the bar cross the arm and thereby suppressing change in the posture of a head slider. SOLUTION: A restraining bar 25 is positioned in a non-contact state in a space formed by the restraining arm folded from a load beam to a head slider 7 side and the load beam. Accordingly, the moving area of the restraining bar 25 at the time of receiving impact becomes a narrow limited area, so that the force produced in the head slider 7 is received by the load beam through a gimbal tongue 8, head slider supporting arm 5, restraining bar 25 and the restraining arm, and that change in the posture of the head slider 7 can be confined in a narrow limited area.  Actually, when the head slider 7 floats over an air film on a magnetic disk, in the case the gimbal 13 and the load beam interfere, each other the head slider fails to follow the waviness or the like of the magnetic disk while maintaining a floating gap close to 20 nm; therefore, the vertical moving area of the head slider 7 is narrowed desirably.

Abstract: PROBLEM TO BE SOLVED: To obtain a gas sensor by which a detection signal at a high-level specific gas concentration can be detected by a method wherein one pair of electrodes of a second oxygen ion pump cell are arranged in a second measuring chamber. SOLUTION: A detected gas is introduced into a first measuring chamber 2 via a first diffused resistor 1, and a first ion pump cell 6 controls the concentration of oxygen in the gas introduced into the first measuring chamber 2. Then, the gas is introduced into a second measuring chamber 4 via a second diffused resistor 3 from the first measuring chamber 2, and a current according to a specific gas concentration flows, via an oxygen ion conductor, across one pair of voltage-applied electrodes 8a, 8b of a second oxygen ion pump cell 8. Both the pair of electrodes 8a, 8b of the second oxygen ion pump cell 8 are arranged inside of the second measuring chamber 4. As a result, oxygen which is pumped out by the second oxygen ion pump cell 8 is returned wholly to the second measuring chamber 4.  Thereby, the amount of oxygen ions which decide the amount of the current flowing to the second oxygen ion pump cell 8 is increased, and a current value, i.e., a sensor output, is increased.

Abstract: PURPOSE:To cancel out remanent magnetsim so as to better the convergence characteristic of electron beams and to enhance picture quality by providing in contact or proximity with a magnetic field correcting device magnets which generate magnetic fields in the opposite direction to remanent magnetism generated in the correcting device. CONSTITUTION:Permanent magnets 35a-25d are disposed at the respective pole ends 34a-34d of the correcting coils 29T, 29B of a magnetic field correcting device 29, with the pole end 34a-side of the magnet 35a being the north pole and the opposite side the south pole, the pole end 34b-side of the magnet 35b being the south pole and the opposite side the north pole, the pole end 34c-side of the magnet 35c being the north pole and the opposite side the south pole, and the pole end 34d-side of the magnet 35d being the south pole and the opposite side the north pole. A core 31 is thereby magnetized in the direction of 36a, 36bb and the direction of this magnetization is opposite to that of remanent magnetism. Therefore the remanent magnetism is completely canceled out by optimization of the magnetic forces of the magnets 35a-35d and errors of convergence of side beams 25B, 25R and a center beam 25G at the center portion of a screen are eliminated. The three electron beams 25B, 25G, 25R are thus correctly converged so as to provide good images.
