摘要： PURPOSE: To obtain a device that can be mounted and removed easily and can retain airtightness, without occupying space for connection by mutually connecting walls made of an insulation material via a peripheral edge airtight packing and with a space filled with dry air. CONSTITUTION: Rooms 1 and 2 are connected mutually and electrically from one to the other, via a contact that passes through walls 6 and 6'. Pairs of contacts 3, 3' and 4, 4' are connected to each other via an electrical connector 9. Also, the contacts 3, 4, 3', and 4' pass through the walls 6 and 6' that demarcate the rooms 1 and 2 and the walls 6 and 6' are made of an insulation material. Then, the walls 6 and 6' are connected to each other by an airtight packing 7 for insulating electrical connection, thus demarcating a space filled with a dry air for securing induction property between the walls. Hence obtaining a device that can be mounted and removed easily does not take up space for connection and can retain airtightness.

摘要： PURPOSE: To make possible close electromagnetic coupling between two coils by providing a first coil of normal conductivity conductive material with many turns, electrically connected in series to a superconducting coil of small self- inductance and a second coil of normal conductivity conductive material with power number of turn, is combined tightly with the first coil. CONSTITUTION: In normal operation, with a closed breaker D a normal current flows in a branch comprising a first coil E1 and a superconducting coil B. When a short circuit is formed, the value of the current exceeds a threshold of the coil B to transfer the coil B into a normal conduction state, resulting in an extremely large value for its resistance. Thereby, almost all of the current flow in the other branch provided with a second coil E2. A faulty current is limited by an intrinsic inductance of the coil E2. Here, the inductance is set sufficient a value so as to reduce the faulty current to a value equal to about 3-4 times the normal current. The residual current is cut off with a breaker D.

摘要： PURPOSE: To form a means for automatically circulate gas between first and second volumes when high intensity breaking current reaches the specified threshold value, use a semi-fixed contact as a pipe for communicating with a third volume, and circulate gas so as to enhance the dielectric quality of gas when the breaking current reaches the upper limit value. CONSTITUTION: When current intensity is higher than a threshold value, while current is maximum, a semi-fixed contact 4 and a piston 8 are moved upward by pressure increase within a volume V1, the piston jumps over an opening 13, the volume V1 communicates with a volume V2. At that time, the pressure in the Volume V1 is higher than that in the volume V2, and a valve 20 is closed. When current is decreased toward zero, pressure in the volume V1 is decreased, the piston 8 is moved downward, the volume V2 is separated from the volume V1. When the pressure in the volume V1 is lowered than that in the volume V2, the valve 20 is opened, gas in the volume V2 is transferred to the volume V1, and gas is contributed to splay to an arc. Since hot gas in the volume V2 goes in from the opening 13 and goes out of the valve 20, gas is circulated.

摘要： PURPOSE: To make it possible to guide the position and/or the speed of a vehicle and simultaneously, to obtain a correct guiding in the lateral direction especially needed for a public transport vehicle by making a magnetic field generating means so as to be constituted of a waveguide connected to the electromagnetic radiation generator having a specific frequency in order to measure the deviation in the lateral direction with respect to the central line of a roadway. CONSTITUTION: A waveguide 1 is buried under the central line of a roadway for running of vehicles and coils 2, 3 provided with magnetic cores 4, 5 are vertically mounted on a vehicle passing over the roadway to be tuned to the radiation frequency (which is relatively low) to be generated from the waveguide 1. One end of the waveguide 1 is connected to the sine wave generator having frequencies 1-100kHz radiating electric power by a connection and the other end of the waveguide 1 is connected to a return line, which forms an extremely relaxed loop so that electric power is not radiated from the loop. Thus, the deviation of the axial line of the vehicle with respect to the central line of the roadway is detected by measuring induced voltages of terminals of the coils.

摘要： PURPOSE: To increase the rigidity of a bearing support by locking a plurality of the rods to be radially expanded from a bearing to support a turbine rotor to a concrete wall. CONSTITUTION: A turbine rotor 10 is supported by a bearing 3 arranged on a suction part 6 side and a bearing 7 arranged inside an axial flow exhaust part 1. The bearing 3 is supported by a concrete stand 4 located on a concrete base plate 5, while the bearing 7 is supported by four radial tie rods 12 arranged in an upright plane orthogonal to the axis of the rotor 10. The tie rods 12 are locked to the thickness of a concrete wall 21 integrated with the base plate 5 around a semi-circular bisected part 22 of an end part opposite to the bearing 7. Since the force from the bearing 7 is not transmitted through a stator 2 or the exhaust part 1, the rotor can withstand a very large incidental out-of- balance force, the integrity in the support of the rotor 10 can be maintained, and the rigidity is increased.

摘要： PURPOSE: To avoid a current to exceed the limit value allowed by a motor and to avoid the risk of demagnetization by including a stator and a rotor, and making the most of the magnetic flux of a magnetic flow to the central part of rotor when the phase advancing and the current of the rotor each large values. CONSTITUTION: The outer frame of a stator has a slot 2. A coil 3 is arranged in the slot 2. A rotor has a plate 4. The magnetizing direction of a magnet 5 is perpendicular to the axial line of a motor and in the direction which orthogonally intersects with the surface of the radial direction passing through the magnet. The magnetic flux of the magnet 5 returns to the direction of the magnet along a returning path. The definition of the rotor is related to the confirmation of the internal self-inductance L, wherein NMAX: NO is 4 or more, and a current I does not exceed the limiting value range of the motor.
