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 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： PURPOSE:To prevent quench by suppressing elastic vibration of a superconducting magnet. CONSTITUTION:A superconducting magnet 4 is disposed on the inside of the side beam 5 of a truck frame through a spacer 6 secured to the side beam 5 and a coupling beam 7 couples the right and left beams 5 in the truck of a magnetic levitation vehicle. Since the superconducting magnet 4 is distribution supported at a large number of points in the side beam 5 with the right and left beams 5 being coupled and since it is subjected to frictional vibration by means of the spacer 6, elastic vibration thereof is suppressed.

摘要： PURPOSE:To improve thermal resistance, anti-corrosion and quality and to reduce manufacturing processes by forming a nozzle hole which faces to a high temperature and high pressure gas in a single sleeve made of a heat- resisting material and by assembling a nozzle unit by inserting the sleeve in the hole of a nozzle. CONSTITUTION:A screen nozzle is made of a copper system material and is assembled by inserting a sleeve 5 made of a heat-resisting material in a nozzle 1 which is a single plate member. In the sleeve 5, a nozzle hole is formed with a throat inlet 2 which has a diameter reducing tapered region 2a, a throat 3 and part of a diameter increasing tapered outlet in sequence. In this case, the points for which you must be most careful are to prevent the turbulence of a gas by making the center of the throat 3 and the center of the diameter increasing tapered outlet 4 in the same axis and the surface of the diameter increasing tapered outlet smoothly continuous and to keep airtight to prevent the flow of the high pressure gas through the inserting surfaces of the nozzle 1 and the sleeve 5 from a high temperature and high pressure side to a low pressure side. For this purpose, a taper 6 is provided at the end of the sleeve 5 and in the inserting hole of the nozzle.

摘要： PURPOSE: To enable a heating of ultra low temperature body such as cryo-panel with a low cost blower by a method wherein a flow of bypassed gas at the outlet port of a heater device to the inlet port of a circulation machine is adjusted in reference to a temperature at the inlet port of the circulation machine.
CONSTITUTION: In the bypass line 7 are provided a thermo-control valve 8 and a thermo-regulator 9 for use in sensing a temperature at the inlet port of the blower and controlling the same. In case that a low temperature gas just after starting a heating operation is flowed into the gas blower inlet port, the thermo-control valve 8 is opened, a high temperature gas at the outlet port of the heater 2 is returned back to the inlet port of the blower 1 so as to increase the temperature at the inlet port of the blower 1. As the temperature of the cryo-panel 3 is increased, a temperature of the return gas is also increased and then a flow rate of the bypassing gas is decreased.

摘要： PURPOSE:To make the construction of a deep layer aeration tank simple and reduce power consumption by providing an air blow port to the upper part of a descending pipe, and connecting the lower part of the descending pipe to one end of an aeraion chamber which is alternately formed with plural pieces of ascending parts and descending parts. CONSTITUTION:The treating liquid supplied through a treating liquid inlet 12 to the lower part in an ascending pipe 1 ascends in the pipe 1, and during the time while it desends together with the air blown through an air blow pipe 11 in a descending pipe 2, air is dessolved in the liquid. Thence, the liquid enters an aerate chamber 3 from the lower part of the pipe 2, and after it repeats the ascending in ascending parts 4 and the descending in desending parts 5, it enters a deaeration part 6, where it is deaerated. Further, while it is maintained of the level constant, it is withdrawn by a circulating pump 8 and is circulated to the pipe 1 through a circulating line 10. When the above-described circulation is repeated, the aeration treatment is accomplished, and the treated liquid is withdrawn through a treated liquid outlet 13.

摘要： PURPOSE:To reduce the produced quantity of surplus sludge through efficient performance of waste water clarification and self-digestion of active sludge by a method wherein waste water treated in the first aeration tank is guided into the second aeration tank where aeration is conducted to digest biological solid in active sludge. CONSTITUTION:Waste water 13 contg. soluble organic material is guided, together with returned active sludge 27, into the first aeration tank 16 where aeration is performed to reach a 90% or more soluble BOD removal ratio. Then, treated waste water 19 contg. active sludge is introduced into the second aeration tank 20, where aeration is conducted until the active sludge concentration becomes lower at the outlet of the second aeration tank than at its inlet, which means sufficient digestion of biological solid in the sludge. Then, the water is guided into a settling tank 24 and solid and liquid are separated.
