Title: Apparatus for exciting superconducting magnet
Inventor: YAMAMOTO SHUNJI
IPC: H01F6/00
Filed: 1985-01-25
Abstract: PURPOSE:To eliminate the initial attenuation of a magnetic field without an external coil by causing an electric current not less than a prescribed value to flow through a superconducting coil at least once after placing a superconductor in the normal conduction state, thereafter reducing the current to the prescribed value or less at least once, and with the state after such current change placing the superconductor in the superconducting state. CONSTITUTION:After the electric current i1 to be caused to flow through a superconducting coil 1 is caused to flow to a prescribed value I0 or more, e.g., more than the prescribed value I0, it is put in a hold state. Thereafter, the current i1 is reduced, and it is held when it reaches a value not greater than the prescribed value I0, e.g., the prescribed value I0. When the shunt current from a permanent current switch 2 to a superconductor 4 is completely exhausted, a heater 22 is turned off. After a superconductor 21 is completely in the superconducting state, the current of a power supply 5 for exciting the superconducting coil is reduced to zero. At this time, the current of the power supply 5 for exciting the superconducting coil reduces, but the current of the superconducting coil 1 does not reduces and becomes a permanent current.

Title: Transferring device
Inventor: FUJITA YOSHIO
IPC: G03G15/16
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To perform stable transfer with a relatively low transferring voltage by providing the static charge discharging means for letting the static charge accumulated between an electrode section and the resistor section by voltage applying means discharged. SOLUTION: This transferring device is provided with a brush 4 (static charge discharging means) for discharging the static charge accumulated between a shaft 2a and a resistance part 2b by static charge applying means 3, held in an outside position on a transfer roller 2 periphery opposing a photoreceptor 1 while in contact with the transfer roller 2, and connected with a line between the shaft 2a and static charge applying means 3. The static charge being charged by a capacter element, is immediately discharged at the time point when the capacter C is short-circuited through the brush 4 brought into contact therewith. Therefore, the discharging time constant of the transfer roller 2 becomes remarkably smaller than heretofore. Moreover, since the static charge is free from remaining on the transfer roller 2 surface, on passing the brush 4, the need of setting the large transferring voltage, in order to stabilize the transferring current flow, is eliminated.

Title: Flow control method and valve applied thereof
Inventor: OGAWA SHIROMICHI
IPC: F16K31/40
Filed: 1981-01-28
Abstract: PURPOSE:To control a large quantity of flow of fluid with small energy by utilizing  pressure energy of fluid by a method wherein a main valve seat is provided employing  with a diaphragm and an auxiliary valve seat is additionally provided at the moving  part of the main valve seat at a pilot type flow controlling valve. CONSTITUTION:When electromagnetic force is weaker than the force of a return spring  8, both the main valve 3 and the auxiliary valve 16 are closed. When the electromagnetic force turns to exceed the force of the spring 8, the auxiliary valve 16 stops at  the position, at which the electromagnetic force or suction force balances with the force of the spring 8. Thenceforth, the pressure in a chamber 15 above the diaphragm  lowers, resulting in allowing the main valve 3 to be lifted up in order to flow a large  quantity of flow therethrough. However, when the main valve 3 is lifted up, the opening area of the auxiliary valve 16 becomes small, resulting in enhancing the pressure  in the chamber 15 so as to press down the main valve 3. While, when the main valve 3  is lowered to excess, the opening area of the auxiliary valve 16 becomes large, resulting in lowering the pressure in the chamber 15 so as to lift up the main valve 3 to  open. In such a manner as described above, because the main valve 3 is moved following to the position of the auxiliary valve 16, a large quantity of flow of fluid can be  controlled with small energy.
