Abstract: PURPOSE:To prevent the lowering of dielectric strength easily, and to miniaturizing an equipment by providing a device supplying and discharging a liquid refrigerant, a vessel recovering the liquid refrigerant and a device returning a gas to an equipment tank from the vessel. CONSTITUTION:When a temperature in an equipment tank 6 lowers to a certain specified value T1 or less, a liquid refrigerant 1 in the equipment tank 6 is transferred to a refrigerant vessel 7 by a refrigerant supply and discharge device 8. SF6 gas melted into the completely transferred refrigerant 1 is degassed by a gas return device 9, and returned into the tank 6.

Abstract: PURPOSE:To prevent a thickness deviation by holding both end faces of a blank straight pipe vertically and in parallel to the shaft core, then by approaching with binder both the end faces according to the deflection quantity with pressing the medium part thereof. CONSTITUTION:The jigs 2a, 2b binding both the end parts of a blank straight pipe 1 vertically and in parallel to the shaft core are oppositely arranged and in case of the bend of the straight pipe 1 being progressed, they are controlled approachably at equal speed each other so as to keep the whole length constantly. The pusher 3 moving forward and backward for the radial direction of the straight pipe is arranged as well. The straight pipe 1 is first held between the jigs 2a, 2b, also pressed in the shaft core direction. A bend work is then performed with holding constantly the whole length of the straight pipe 1 by approaching the jigs 2a, 2b at equal speed, simultaneously with adding the bend load of the pusher 3. With said method the thickness deviation is prevented due to the compression and elongation of the inner and outer sides of the straight pipe 1 being not caused.

IPC: G11B5/588
Filed: 1987-08-06
Abstract: PURPOSE:To lower a level of resonance to be caused by a spring by winding a second coil on a first coil. CONSTITUTION:The first coil 44 is wound around a coil bobbin 43 on the first coil 44, further the second coil 60 is wound in plural layers on the outer surface, and the start and the end parts of the second coil are short-circuited. Accordingly, the second coil 60 generates a counter electromotive force e' when a current flows through the coil 44, and due to the force e', a current I' is generated in the direction inverse to the direction of electrification of the coil 44. Thus a force F' is generated which is inverse to the force F generated by the first coil, so that the resonance level is sufficiently lowered. The magnitude of the damping force F' can be regulated by the number of windings and layers of the second coil wound around the bobbin 43.
