Title: Magnetic bearing device
Inventor: YAMAMOTO MASAYUKI
IPC: F16C32/04
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption and cost, and simplify and miniaturize equipment by generating bias magnetic flux by a permanent magnet, and by generating a control magnetic flux by radial position control winding so that it is different from the bias magnetic flux by ±2 poles in the number of control flux. SOLUTION: With this device, four pole symmetrical magnetic flux Ψ4 is generated by a permanent magnet 41. Further, when current flows in a radial position control winding 15, two pole symmetrical magnetic flux Ψ2 is generated. When the current in the direction shown in the drawing flows to a Nα winding, in a gap g1, Ψ2 and Ψ4 are cancelled to decrease the magnetic flux density, but in a gap g3, the magnetic flux density is increased reversely. As a result, a radial force Fx acting in the negative direction on the x axis is generated in a rotor 1. Further, when current flows in the reverse direction in the Nα winding, the radial force is directed in the opposite direction.

Further, the lambda/d of the 1st hologram H1 is, for example, 0.7, so the diffraction efficiency which is almost as high as that of the P polarization is obtained even by the P polarization. Further, the 2nd hologram H2 is so constituted that lambda/d=0.7, so the high diffraction efficiency which is similar to that of the 1st hologram is maintained.

Filed: 1990-10-17
Abstract: PURPOSE:To eliminate unevenness of battery characteristics by storing a pole plate, mainly composed of a hydrogen absorptive alloy, in an activation processing vessel, and introducing hydrogen gas or inert gas as a thermal medium in the activation processing vessel before a process of absorbing and releasing hydrogen is applied to the pole plate. CONSTITUTION:A pole plate, mainly composed of hydrogen absorptive alloy, is stored in an activation processing vessel, and after its inside is placed in a vacuum condition and heated, inert gas or hydrogen gas is introduced as a thermal medium into the vessel, thereafter its inside is placed again in the vacuum condition and cooled. Next, after the insert gas or hydrogen gas is again introduced as a thermal medium into the vessel, its inside is placed in the vacuum condition to introduce the hydrogen gas so as to absorb and release hydrogen. Accordingly, adsorbed gas and moisture for impeding reaction between the hydrogen absorptive alloy and the hydrogen gas are sufficiently removed, and further a sufficient amount of hydrogen can be absorbed and released so as to facilitate destruction of an oxide film to more extent. In this way, unevenness of battery characteristics can be eliminated.
