摘要： PROBLEM TO BE SOLVED: To make it possible to prevent the lowering of fixing strength to a side wall for a long period of time, by a method wherein the outer circumference of the cross section of the large diameter part or the small diameter part of buried metal is formed in a positive circular shape. SOLUTION: Flat parts 5C are symmetrically formed on both sides of the center of an arcuate large diameter part formed on the outer circumference of a buried metal 5A. Besides, the end of the flat part 5C is chamfered a little for the purpose of avoiding concentration of the stress of an insulating layer. In this ground coil for a magnetic levitation railway having the flat part 5c, rotation can be prevented by the heat cycle in operation for a long period of time by the flat part 5c, even when the buried metal 5A and the insulating layer are separated at their boundary surface. As a result, the vibration caused by the electromagnetic force of the ground coil for the magnetic levitation railway due to the increase of the gap between the buried metal and the insulating layer resulted from the above-mentioned rotation. Also, the generation of the vicious cycle of increase of the gap by the above-mentioned vibration and the exfoliation of the adjacently provided buried metal 5A can be prevented.

CONSTITUTION:In a magnetic levitation railroad, side wall levitation guide coils 4 are arranged continuously on the opposite sides of a U-shaped track(not shown) and the guide coils 4 are interacted with a superconducting coil mounted on a vehicle(not shown) thus running the vehicle while levitating. The side wall guide coils 4 comprise upper and lower unit coils null flux connected in 8-shape and electromagnetic induction is utilized so that no power is fed externally. Projecting and recessed fitting parts 18 are molded, respectively, on the opposite fades of the guide coil 4 contacting with adjacent coils. A large spring hole is employed as a coil fixing hole 17. According to the invention, the side wall levitation guide coil 4 can be fixed easily at a correct position.

摘要： PURPOSE:To inhibit the torque shock of a motor on stating by mounting a nonlinear type resistor between an armature of an exciter and a field winding of a generator. CONSTITUTION:A diesel engine 1 is run at a constant speed at every notch by the indications of notches for a master controller. Power generated by an exciter 3 is fed to a field winding 10 through a nonlinear type resistor 11. A DC motor 14 is supplied with power generated by a separated exciting DC generator 2. Field currents flowing through the field winding 10 of the separated exciting DC generator 2 are inhibited because the resistance value of a nonlinear resistor 12 is high on starting. Accordingly, sudden torque fluctuation can be suppressed on starting, thus reducing a torque shock, then smoothly operating the DC motor 14.

摘要： PURPOSE:To suppress the unbalance of a voltage of a load connected to a number-of-phase converter by providing a middle terminal having different winding distribution at the main winding of the converter and selectively connecting the output winding of a transformer to the main winding in response to the capacity of the load. CONSTITUTION:A number-of-phase converter 21 has a U-V terminal, a main winding 21a including the middle terminal of U1-V1 and an auxiliary winding 21b including a Z-W terminal. The terminals U, V, U1, V1 ofthe winding 21a are respectively connected to the output winding and hence the tertiary winding 14 of a transformer 10 through changeover switches 22A-22D. When the capacity of a load is less, the switches 22C, 22B are closed to connect the terminals U1, V of the winding 21a to the tertiary winding 14 of the transformer 10. When the capacity of the load is large, the switches 22A, 22D are closed to connect the terminals U, V1 of the winding 21a to the tertiary winding 14 of the transformer 10. When the capacity of the load is middle, the switches 22A, 22B are closed to connect the terminals U, V of the winding 21a to the tertiary winding 14 of the transformer 10.

摘要： PURPOSE:To improve comfortableness by providing fitting parts on the opposing surfaces of adjacent levitation coils on the side wall and fitting them at the time of fixing. CONSTITUTION:Since protruding and recessed fitting parts 2 are provided on the opposing surfaces of adjacent levitation guide coils 1 on the side wall and fit each other to define relative positions of both coils 1, planeness is achieved naturally for adjacent levitation guide coils 1 on the side wall. Since magnetic balance position of laterally opposing levitation guide coils 1a, 1b on the side wall does not shift laterally, a vehicle 10 does not shift to the right or left wall. Consequently, the laterally opposing levitation guide coils 1a, 1b on the side wall receive same amount of flux from a superconducting coil 9 mounted on the vehicle 10 to eliminate voltage difference between the coils 1a, 1b and thereby the vehicle 10 is steered straight without causing vibration. According to the constitution, comfortableness can be improved.

摘要： PURPOSE:To eliminate the interruption of a power source supply to a load side even if a power source is interrupted due to the passage of a section by forming a forcible closing circuit of an auxiliary coil when the circuit power source of a motor is interrupted to be reenergized. CONSTITUTION:When a voltage detector 14 is operated, an auxiliary coil contactor 17 and a man circuit contactor 18 are excited, and the main coil 11Mm and the auxiliary coil 11Ma of a single phase induction motor 11M of a motor generator 11 are excited. When the output frequency of a generator 11G becomes the prescribed frequency or higher, a frequency relay 16 is excited to excite a load contactor 24. When the frequency is further raised, a time limiting relay 27 is excited, and the contactor 17 is demagnetized. When a motor power source 13 is interrupted, the relay 27 is first demagnetized and the contactor 17 is excited. Accordingly, it can be restarted without opening a load circuit at the reenergizing time.
