Title: Magnetic bearing device and control thereof
Inventor: KANEMITSU YOICHI
IPC: F16C32/04
Filed: 1992-07-23
Abstract: PURPOSE:To provide a magnetic bearing device capable of being miniatuaized and used for a small-sized rotating machine and a method for controlling it. CONSTITUTION:In a magnetic bearing device, the movement of a rotating body 32 in its radial direction is passively stabilized by utilization of attracting and repelling force of permanent magnets 29, 31, 36 and 37, and the rotating body 32 is supported by a stator 33 in a non-contact manner. A permanent magnet 36 attached to the stator 33 is made movable in the direction of the axis by means of a piezoelectric element. The piezoelectric element is actuated on the basis of a displacement signal that represents the displacement of the rotating body 32 in the direction of the axis, and hence the attracting and repelling force of the permanent magnets 36 and 37 in the direction of the axis that act between the rotating body 32 and the stator 33 and adjusted, whereby the movement of the rotating body 32 in the direction of the axis is controlled.

Title: Circuit for optical reception panel
Inventor: HAYASHI KAZUYA
IPC: H04B10/69
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical reception panel in which a level of an optical input signal is measured and the optical input signal is attenuated at an attenuation rate desired by a user. SOLUTION: A variable optical attenuator 11 attenuates an optical input signal at an attenuation rate designated by a user by using an attenuation level selector switch 12. An optical reception section 13 converts the optical signal into an electric signal with a voltage in response to its light intensity. An equalization amplifier circuit 14 amplifies the signal so that the amplitude of the signal is constant. An identification circuit 16 gives a signal level to a code conversion circuit 18, which converts the received signal into a signal corresponding to a signal system of a supplied destination. Since the user can designate the attenuation rate, the level of the optical input signal is detected by measuring an output of the optical reception section 13.  Furthermore, since the user can designate the attenuation rate, the optical input signal is attenuated at a desired attenuation rate.
