摘要： PURPOSE:To suppress the rise of the centroid position of a vehicle body by so correcting a vehicle body target inclining angle calculated from the traveling speed of a vehicle, a cant or a curvature as to minimize a displacement of the body to a truck and controlling it. CONSTITUTION:An arithmetic unit 9 so supplies control signals j1, j2 that displacements delta1, delta2 of a vehicle body 1 to a truck 2 output from displacement detectors 7a, 7b attain predetermined values to hydraulic pressure operating mechanisms 5a, 5b. When the value of its traveling distance becomes the value a correcting distance equivalent to its traveling speed before the starting point of a curved route, a target inclining angle is obtained from the traveling speed of the body, radius of curvature, a cant angle, a traveling position, etc. Then, an interval between the body 1 and the truck 2 is held at the minimum allowable interval, and the signals j1, j2 are so output that the inclining angle of the body 1 to the truck 2 becomes the target inclining angle.

摘要： PURPOSE: To obtain a magnetic levitation mechanism in which a vehicle is levitated perfectly without touching a ground facility at all while ensuring all functions of propulsion and guide by improving the arrangement of electri cally conductive plates opposing a magnet thereby generating a levitation force effectively. CONSTITUTION: The magnetic levitation mechanism comprises a pair of rotors 3-1, 3-2 arranged in a cross-section in the advancing direction of a mobile body, and electrically conductive plates 5-1, 5-2, 5-3 arranged continuously in the moving direction of the mobile body while being split such that the center of rotation of the rotors 3-1, 3-2 are located asymmetrically in a cross-section. The mobile is thrust by the difference of magnetic drag in the longitudinal direction between the rotors 3-1, 3-2 and when the mobile body is deviated perpendicularly to the advancing direction, a force for returning the mobile back to the center is generated.

摘要： PROBLEM TO BE SOLVED: To get favorable propulsion, levitation, and guidance performance while lessening vibration of a superconducting magnet by exciting force of an 8-shaped coil for propelling, levitating, and guiding a vehicle, in a magnetic levitation movable body system. SOLUTION: To reduce the vibration of the superconducting magnet, it needs to select a coil pitch that exciting force frequency and a generated vibration mode do not match with each other. In 90° pitch in which four pieces of coils are provided for 360° of electric angle of the superconducting magnet, the exciting force of the adjacent coil comes to the same phase, and resonance frequency which causes the vibration mode of the superconducting magnet as a whole becomes large, whereas the exciting frequency is small. Accordingly, as a coil pitch for the vibration of the superconducting magnet, a pitch of 90° is advantageous. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To correct the convergence drifted in accompany with the temperature rise of a deflection yoke by mounting a temperature variable resisting means in parallel with a variable resisting means of a correcting circuit mounted on a terminal board. SOLUTION: When an operating temperature of a deflection yoke rises, a resistance value of a temperature variable resisting means 5 having a negative rate of change to the temperature change is reduced, and the electric current flowing in the temperature variable resisting means 5 is increased. Here, the combined resistance of the temperature variable resisting means 5 and an adjustment volume 3 is reduced. As a result, when an upper half of an image plane is deflected, the electric current flowing in a diode D5 is increased, and the electric current flowing in a coil 44 is increased in comparison with the electric current flowing in a coil 43, whereby the misconvergence can be corrected. In a case when a lower half of the image plane is deflected, the electric current flowing in the diode D4 is increased, and the relationship between the electric current flowing in the coil 44 and that in the coil 43 is reversed to that in the deflection of the upper half of the image plane.

摘要： PROBLEM TO BE SOLVED: To provide a cathode-ray tube which is high in productivity with a long service life by applying magnetic power with a specified value or more of a specific magnetic permeability onto an internal conductive film provided on the funnel inner surface conductive to a fluorescent screen and a shadow mask, so as to easily shield the external magnetic field and to dispense with a shielding plate which is inferior in assembling workability and having a possibility of gas discharge. SOLUTION: A fluorescent screen 3 is provided t the inner surface of a panel screen part 1a of a cathode-ray tube body 1, and a shadow mask 4 is arranged on the inside through a frame 5. The inner surface of a funnel part 1c is provided with a conductive magnetic power layer 7, formed by applying magnetic powder with a specific magnetic permeability of 100 or more onto an internal conductive film, so as to shield the external magnetic field and to mask conductive a high pressure lead-in part 6, the fluorescent screen 3 and the shadow mask 4. A deflection coil 9 is arranged on the outside, and an electron beam 8 from an electron gun 2, arranged inside a neck part 1d, is deflected to make the fluorescent screen 3 emit light. If necessary, the magnetic powder is also applied to an external conductive coat 13 to improve the magnetic shielding performance.

摘要： PROBLEM TO BE SOLVED: To facilitate the adjustment of convergence by separately providing a magnet plate for four-pole from each magnet plate in the coaxial condition with each magnet plate. SOLUTION: A pair of magnet plates 12X for four-pole, which are provided in a holder 11 of a convergence adjusting means, are arranged in the coaxial condition between a pair of magnet plates 12A for double-pole and a pair of magnet plates 12B for four-pole through a spacer 13. This magnet plate 12X can be separately operated, and rotated around a neck part so as to separate an electron beam for R (red) and an electron beam for B (blue) in relation to an electron beam for G (green) interposed between both the electron beams. As a result, light emission is visually recognized as one point emission, but each phosphor layer, which is emitting light, can be separately recognized. Consequently, at the time of observing a display surface and while adjusting the convergence, degree of freedom is given to the adjustment width, and convergence can be accurately adjusted.
