摘要： PROBLEM TO BE SOLVED: To provide a compact, lightweight braking device for rolling stock, capable of holding an emergency brake for many hours during power failure and dispensing with a large number of accumulators. SOLUTION: An accumulator 6 is connected to piston side oil chambers 4A-4D of brake cylinders 1A-1D, and rod side oil chamber 5A-5D are selectively connected to an accumulator 10 or a tank 11 through solenoid selector valves 9A, 9C. Brake shoes 3A-3D are put in braking action by braking pressure (pressure of the accumulator 6) continuously led into the piston side oil chambers 4A-4D. There is therefore no hindrance to a brake even with an oil leak or the like in a circuit on the accumulator 10 side. A safety solenoid selector valve 21 and a relief valve 22 are series-interposed at a branch circuit to the tank 11 from a circuit of the accumulator 6, and at the time of power failure the safety solenoid selector valve 21 is opened to relieve braking pressure to the set pressure of the relief valve 22. A hydraulic source 16 is held in common to other hydraulic equipment.

摘要： PROBLEM TO BE SOLVED: To provide a wheel tread increase sticking method and its device capable of reducing the maintenance work, and obtaining high sticking force of a wheel tread with a simple configuration.
SOLUTION: An electromagnet device 9 is arranged in a vicinity of a rail 1 while facing a wheel tread 4 of a railroad vehicle. The temperature of the surface of the wheel tread 4 is raised by the core loss of a wheel 3 generated through the electromagnetic induction from the electromagnet device 9 while the railroad vehicle is running. The viscosity of the fluid interposed between the wheel 3 and the rail 1 is reduced by the temperature rise, and the sticking force of the wheel tread 4 can be enhanced.

摘要： PROBLEM TO BE SOLVED: To reduce a cost by facilitating the magnetization of a permanent magnet being used in a load reducer of a flywheel rotator or the like. SOLUTION: A large number of tile-like permanent magnets 14 are bonded in two rows in ring shapes at a specified interval a1 to one surface of a ring- like basic body, i.e., a yoke 10. The permanent magnets 14 are magnetized in the thickness direction wherein N-poles are arranged oppositely to a target, (e.g. a rotator for flywheel) in the first row whereas S-poles are arranged oppositely to the target in the second row. The permanent magnets attract the target to lighten the load thereof thus lightening the load of a bearing. Since a large number of permanent magnets 14 in the form of tile-like pieces are arranged in ring shapes, a permanent magnet of any size exhibiting any attraction force can be produced easily and the cost can be reduced greatly because a large scale magnetizer is not required.
