摘要： PURPOSE:To prevent thrust force from becoming short or being varied largely by detecting the amount of extension and retraction of vehicle length and adjusting the longitudinal displacement of a secondary thrusting coil according to the detected result, in a coupling device suitable for connecting together floating type vehicles. CONSTITUTION:An articulated truck 1 provided with magnets 2 comprising a superconductive coil is connected to a body 3 in longitudinal direction by means of an anchor 4. Both front and rear bodies 3 and 3a are supported by supporting springs 5 and 5a on both ends of the articulated truck 1. Also, the body 3 is connected to the body 3a by means of a body-to-body connect rod 6 provided with position adjusting mechanism 7 for length adjustment. The position adjusting mechanism 7 is so constructed that, when the body is extended largely due to temperature rise of it in mid summer, a bolt 17 is inserted into the hole 16a of an outer tube 12 and the hole 15b of and inner material 13 and, when the body is retracted largely due to temperature lowering of it in mid winter, the bolt 17 is inserted into the hole 16a of the outer tube 12 and the hole 16b of the inner material 13, to adjust a distance between the bodies 3 and 3a.

摘要： PURPOSE:To obtain a light weight magnetic shield excellent in shielding by disposing a magnetic member having higher permeability and saturation magnetic flux density, as compared with other parts, between superconducting coils facing the opposite side parts at the end of a superconducting coil group in the advancing direction of vehicle. CONSTITUTION:A magnetic shield member 62 disposed inside a car body 11 comprises a U-shaped main magnetic shield plate 62a thin enough not to be saturated magnetically disposed on the floor of the car body 11 and the region under the side wall. Sub-magnetic shield plates 62b, 62c having higher permeability and saturation magnetic flux density than other parts are disposed in the regions proximate to superconducting coils 21a, 21c facing the superconducting coils on the other side disposed at the opposite ends in the advancing direction of the vehicle where the leakage flux and the flux density are high. Since a circuit for shunting most of leakage flux from the superconducting coils 21a, 21c to the sub-magnetic shield plates 62b, 62c is established, flux leakage into the vehicle can be reduced significantly.

摘要： PURPOSE:To provide light and strong out-of-plane rigidity and suppress the lowering of magnetic permeability by making a panel wherein high magnetic permeable metal panel is used for at least one front member out of two front members and light alloy metal plate is used for the other front member and honeycombs made of light alloy metal is used for cores and these front member and core material are brazed. CONSTITUTION:A honeycomb structured core 3 made of light allay Al alloy, for example) is held between a front member 1 made of high magnetic permeable metal and a front member 2 made of light alloy Al alloy, for example), and these are connected to each other by brazing to constitute a magnetic shield material 10. In this case, a highly magnetic permeable plate on which light alloy 4 is plated beforehand is used for the front member 1. Thus, the highly magnetic permeable plate 1 is supported by the honeycomb panel 3, as a whole. Since this constitution provides the same effect as that in the case where fine mesh grid-like skeletons are arranged, high strength and out-of-plane rigidity can be given to the magnetism shield material itself without employing reinforcing skeletons.

摘要： PURPOSE:To make improvements in smoothenedness and airtightness by installing a bellows, made up into the same form as a body section and formed with a nonflexible member in space between car bodies, an elastic body inserted into space between this bellows and the car body and an airtightness keeping means plus an air spring set up in a truck, supporting the bellows, respectively. CONSTITUTION:An interval between car bodies 1 and 1 is composed of a bellows 5 provided with a through passage (as this bellows is of magnetic shield, it is composed of a steel sheet) and connected to each other, while tare weight and magnetic attraction of the bellows 5 are supported by an air spring 4 with an automatic level-control mechanism. Since the car body 1 and the bellows 5 are supported by an air spring 3 with the automatic level-control mechanism together with an interval between the car body 1 and a truck 2 likewise, it is such a structure that respective members become smoothed with one another. A relative position between the car body 1 and the bellows 5 should be made so as to be absorbed by rubber 6, and as for airtightness maintenance, it should be a bellows structure to be met by a rubber bellows 7 installed at the car inside.

摘要： PURPOSE:To obtain sufficiently big damping even against a small yaw angle by constructing the title device of a connecting body pin-connected rotatably, two link mechanisms and dampers mounted at the link mechanisms. CONSTITUTION:The crosswise displacement of each body 2 is restrained by pin-connecting the bodies 2 by means of a connecting body 9 rotatable around each axis. Yaw angle damping mechanisms 10 for enlarging the longitudinal displacement, i.e., link mechanisms are provided on both right and left sides between the bodies 2, and a damper is placed at the tip of this link mechanism. As a result, the longitudinal displacement is enlarged by (n) times, and the damping force of the damper becomes Cn. This damping force is then reverted by an enlarging mechanism, increased by (n) times and thus becomes Cn , where the damping of a single damping body is C. This damping force Cn acts upon the right and left sides of the body edges, and the damping moment against the yaw angle of Cn .a acts upon a body 1, where (a) is a lateral spacing. Accordingly, even a damper with normal capacity C can put out the damping force of n times.

摘要： PURPOSE:To prevent the magnetic flux entering a through-passage, allow the relative displacement between vehicles, and keep the airtightness of the through- passage. CONSTITUTION:Parts of magnetic shield sheets 1, 2 are overlapped with appropriate space, and the magnetic shield sheets 1, 2 are connected to each other with a hood 5. The magnetic flux passing through the clearance of the magnetic shield sheets is guided to the outer magnetic shield sheet, and the leakage of the magnetic flux into a through-passage can be prevented. The airtightness of the through-passage part can be secured by connecting the clearance between the magnetic shield sheets with the hood without interfering the relative displacement between the vehicles.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive branching device for monorail. SOLUTION: This device comprises connecting plates 31 on both side surfaces of the connection part of branching girders 4 and 3. One-side ends of the connecting plates 31 for traveling the guide wheel and stable wheel of a monorail vehicle are connected to the girder 3 by pins 33. The other ends thereof are also connected by pins 35, and the brackets thereof are elliptic. The connecting plate 31i located on the circular inner side between the pin 33 and the pin 35 is connected through a link 37 to bend the connecting plate 31i inward. The connecting plate 31o located on the circular outer side is pressed by a roller 39 from the girder 3 to the circular outer side. Accordingly, the traveling surface of the connection part of the girders 3 and 4 is made circular, so that the deterioration in comfortableness can be prevented.
