摘要： PROBLEM TO BE SOLVED: To provide a method and equipment for keeping the stable magnetic coupling condition between a primary and a secondary coils. SOLUTION: An inverter circuit 22 installed in a power equipment 20 is provided with a switching circuit 26 for switching the voltage from a source of DC power 21 to the one having positive and negative voltages and then applying it to a primary coil 23. The switching circuit 26 switches the DC power according to a control circuit 27 and applies AC voltage E1 with one cycle, constituted of positive pulse voltage P1 of a large pulse duration and negative voltage P2 of a small pulse duration, to the primary coil 23. Due to this operation, current S1 in the primary coil 23 includes a DC component, which generates an attractive force between cores 24, 13 of the primary and the secondary coil. With this attractive force, the primary and the secondary cools 23, 12 are kept in a stable coupled condition.

摘要： PURPOSE:To obtain a large levitation force by fastening permanent magnets with reversed polarities from each other to both pole faces of an electromagnet. CONSTITUTION:Levitating magnets 6 are fitted to four corners of the top surface of a carrier truck 7. Levitating rails 4 composed of magnetic material and primary side coils 9 of a linear motor are fixed to the ceiling 8. In said levitating magnet 6, excitation windings 5 are provided at upward U-shaped cores 3 to constitute electromagnets 2 and permanent magnets 1, 1' are fastened to pole faces of said electromagnet 2. In this case, the polarity of one permanent magnet 1 coincides with that of the electromagnet 2 and the other permanent magnet 1' is provided with a reversed polarity. Thus, the magnetic flux of said permanent magnets can be used effectively to obtain a large levitation force.

摘要： PURPOSE:To conduct a branch action and a return action quickly by constituting a reference rail between a branch point and a separation point through a movable rail and by reentering said movable rail through a branch command. CONSTITUTION:When a running gear 9 goes straight on through a branch apparatus, a movable rail 7 is at an equal height of the common rail level of a reference rail 1 and a branch rail 3. Accordingly, said running gear 9 is not affected by said branch rail 3 but goes straight on along the reference rail 1 because of inertia in the direction of rectilinear motion. On the other hand, when the running gear 9 is to move to the branch rail 3, a branch command signal is sent to an actuator 8 and the movable rail 7 reenters so that a difference in level is produced between the movable rail and the branch rail 3. Thus, a horizontal force in addition to a vertical force, is produced to guide the running gear 9 to the branch rail 3.

摘要： PURPOSE:To enable transferring magnetic flux for a long distance almost without a loss by perfectly intercepting the leakage of the magnetic flux by a superconducting material layer which covers a core. CONSTITUTION:A superconducting material layer 2 covers around a core 1 which is twisted with ferromagnetic material small diameter wires and a coolant passage 3 covers around the superconducting material layer 2. The superconducting material layer 2 may be installed outside the coolant passage 3. In such a transfer wire, the superconducting material layer 2 has perfect diamagnetic characteristics and no line of magnetic force invades inside, so the magnetic flux in the core 1 is perfectly intercepted against outside and no leakage is generated. This enables transferring without the loss of the magnetic flux even for the long transfer wire.

摘要： PURPOSE:To ensure the climbing capacity by setting the interval in arrangement of a detected body closer in the upper slope than in a level section of the running path of a rolling stock. CONSTITUTION:A crossover type induction radio line 5 is provided along a rail 1. For a rolling stock 4 an antenna 6 is provided to receive the electromagnetic wave radiated from the line 5. On the other hand, an inverter 10, power source for a linear motor 9, is provided to the rolling stock 4. The inverter 10 changes the power frequency in proportion to the frequency of a pulse train 11 obtained from the periodic polarity change of the electromagnetic wave detected by the antenna 6. The interval of intersection of the crossover type induction radio line 5 is set closer in the upper slope section 8. Thus, the thrust in the slope section 8 is increased.
