摘要： PROBLEM TO BE SOLVED: To reduce the abrasion of the treads of a wheel and a rail, and further the abrasion of a brake block, a brake disc, or the like, and a current collecting shoe, by installing a magnetic field generating means for applying the magnetic field to the tread of the rail, and that of the wheel during the travelling of the wheel on the rail. SOLUTION: The treads of the wheels 2 are rolled and travelled on the treads of the rails while keeping the face contact. One edge part of each axle 3 is magnetized to be N pole, and the other edge part is magnetized to be S pole. As the result of the same, the line of magnetic force generated from the N pole of the axle 3 at a front side, is passed through the S pole of the axle 3, and is returned to a start position successively through the wheel 2, one of the iron rails 5, the wheel 2 at a rear side, the axle 3, the rail 5 and the wheel 2. Whereby the magnetic field generated from the axle 3, acts on the tread of the rail 5 and the tread of the wheel 2 at all times, the absorption of oxygen is energized, an oxide film is formed, and the abrasion powder is refined, so that the abrasion is reduced. Further the abrasion of a brake disc and a current collecting shoe can be similarly reduced.

摘要： PROBLEM TO BE SOLVED: To appropriately control velocity of a movable member at the time of closing operation and breaking operation. SOLUTION: A magnetic circuit comprises a fixed member; a permanent magnet: the movable member; and an electromagnet 9 wherein a reactor 23, which is electrically connected in series with the electromagnet, is provided in a position not interlinking with a magnetic flux of the magnetic circuit. Thereby, at the time of closing or breaking operation, when the magnetic flux of the magnetic circuit is changed and a counterelectromotive current is induced in the electromagnet, by discharging the energy accumulated in the reactor, a decline of excited current of the electromagnet generated by the counterelectromotive current is compensated. thus the decline of moving velocity of the movable member at the time of closing or breaking can be prevented.

摘要： PROBLEM TO BE SOLVED: To enable a simulation test without lifting and lowering a car frame actually by fixing a guide wheel displacement mechanism on a pedestal on which the car frame is hung in such a manner that it opposes to a guide wheel and displacing the guide wheel by a control means in the direction of deflection of a guide rail. SOLUTION: Displacement which is equivalent to deflection of a guide rail in A and B directions is given to guide wheels 8a, 8b of each roller guide by rotating a servo motor 61 of a guide wheel displacement mechanism 50 in the direction of forward and backward directions. In the same way, displacement which is equivalent to deflection of a guide rail in C direction is given to a guide wheel 8c of each roller guide by rotating a servo motor 65 in the direction of forward and backward directions. Consequently, it is possible to simulate a condition in which all the guide wheels are forcedly displaced due to deflection of the guide rail in the same way as the time when a car frame to be tested ascends and descends actually without lifting and lowering the car frame and observe a very high speed lift test and vibration phenomenon generated in accordance with its ascent and descent for a long time.

摘要： PURPOSE:To prevent the erroneous conversion of angle data by providing a low-pass filter with respect to the noise of a power supply system superposed on the signal from a sensor and providing a digital filter with respect to the noise at the time of the conversion to a digital signal. CONSTITUTION:When high frequency noise is superposed on the angular velocity data fomega from a gas rate gyroscopic sensor 11, said noise is removed by a low- pass filter 12. The data fomega is amplified to data kfomega through an amplifier 13 and the data kfomega is converted to digital data by an A/D converter 14 while the digital data is further integrated at every unit time by an integration circuit 15 to be outputted as angle data theta. The removal of the noise or unexpected noise superposed on the original signal is executed at the time of A/D conversion by an index smoothing/moving averaging processing part 16. Index smoothing processing applies differential approximation to the superposed noise component using differential operation to remove said noise component. Moving averaging processing applies averaging operation to the unexpected noise to remove the same. By this method, even minute angular velocity data is accurately outputted as angle data.
