Title: Magnetic bearing control system
Inventor: MORII SHIGEKI
IPC: F16C32/04
Filed: 1986-05-02
Abstract: PURPOSE:To stabilize a floating object, by making the signals, which are obtaind by measuring the position of the floating object from reciprocal directions by means of the first and second position sensors, pass through the filters, whose passing and interrupting-characteristics are diametrically opposite to each other, respectively, and adding both before feeding back the result. CONSTITUTION:After the signal from the first position sensor 1 passes through the first filter 8 and after the signal from the second position sensor 7 passes through the second filter 9, both signals are added by an adding machine 10 and are input into a control circuit 3 via a position feedback gain 2. Accordingly, the ratio between the signal for the force F of a magnetic bearing and that for the displacement D, or F/D, obtaind only through the route of the sensor 1 is diametrically opposite to that through the route of the sensor 7. As a result, the damping characteristics of the magnet bearing are improved as shown in the figure, i, e., the dotted line E in the frequency domain between fc1 and fc2 is replaced by the solid line D, or the stabilizing force. Therefore, the natural frequency corresponding to the above domain is stabilized, thereby preventing the divergencetrending vibration from occurring. As a result, the control over the magnetic bearing, which is used to keep a floating object afloat in a stable manner, can be ensured.

Title: Method and apparatus for signal reception and demodulation
Inventor: YOSHIZAKI ATSUHIRO
IPC: H04B3/54
Filed: 1980-07-28
Abstract: PURPOSE:To enable reception with S/N, by subtracting a stationary error component when no signal is transmitted from a reception signal. CONSTITUTION:A multiplication circuit 22 multiplies a phase voltage Va phase- shifted by 90 deg. at a 90 deg.-advance phase-shifting circuit 20 with an output I0 of a zero phase CT, and a multiplication circuit 23 multiplies the phase voltage Va with the output I0 of the zero phase CT phase-shifted by 90 deg. at a 90 deg. lagging circuit 21. An adder 24 adds the output of the multiplication circuits 22, 23 and applies the result to a subtraction circuit 26 and a holding circuit 25. A reception signal is obtained from the circuit 26. In this case, the zero phase voltage is expressed as Va sin(omegat), the signal component of the zero phase current I0 is as Is sin(omegat+90 deg.), and stationary error of the zero phase current I0 is as Ie sin(omegat+phi). Thus, since the output of the adder 24 is (VaXIs+VaXIe sin phi), the output of the circuit 26 is only the signal component VaXI0, by storing the output Va sin phi of the adder 24 immediately before the reception to the holding circuit 25.
