Inventor: SHIBUTA DAISUKE
IPC: C01G30/00
Filed: 1992-03-27
Abstract: PURPOSE:To provide a whitish superconducting powder showing white or a color, having electrically conductive function. CONSTITUTION:In coating the surface of inorganic powder with tin oxide doped with antimony oxide, an aqueous solution of hydrochloric acid of tin chloride and an alkali aqueous solution are simultaneously added to an aqueous solution suspending the inorganic powder, the inorganic powder is coated with tin hydrate precipitated by hydrolysis, successively a mixed aqueous solution of hydrochloric acid of tin chloride and antimony chloride and the alkali aqueous solution are simultaneously added to the solution to give a tin hydrate containing antimony hydrate coprecipitated on the inorganic powder coated with the tin hydrate. The tin hydrate is heated and burnt and an oxide tin layer doped with antimony oxide is formed to produce electrically conductive powder. Consequently, powder obtained by this method is observed to have much more improved effects on electrical conductivity than powder coated with the same amount by the conventional method and a raw material supply source is widened.

Title: Magnetic bearing control system
Inventor: MORII SHIGEKI
IPC: F16C32/04
Filed: 1986-05-02
Abstract: PURPOSE:To reduce the occurrence of the instability-oriented force in the medium & high frequency domains so as to maintain the stability of a revolving body, by making the output signal from a control circuit pass through a low-pass filter, in which the cut-off frequency varies in proportion to the rotating-speed signal, and then inputting the result into an electromagnet. CONSTITUTION:The signal, whose frequency is greater than the cut-off frequency fc, of the output signals form a control circuit 3 is eliminated by a low-pass filter 7. In other words, until a revolving body 5 comes completely out of the entire critical speeds, the cut-off frequency fc of the filter 7 corresponds to the value of a pre-set value generator 9. Therefore, a magnetic bearing 6 acts as if it damps the vibration caused by the unbalanced force. The critical speed is defined as a rotating speed at which the rotating speed coincides with the natural frequency. Therefore, for the rotating speed exceeding the critical speed, the cut-off frequency fc of the filter 7 indicates the value of the rotating speed. Accordingly, for the natural frequency exceeding the rotating speed, the magnet bearing does not act. As a result, the revolving body 5 is kept stable owing to the internal damping effect. On the contrary, for the natural frequency lower than the rotating speed, the damping effect is exercised. Therefore, the revolving body 5 is free from the occurrence of large vibration and can be operated stably up to the maximum rotating speed.

Filed: 1981-07-03
Abstract: PURPOSE:To reduce carrier leakage at a pedestal part by canceling a subcarrier component, induced externally on a V axis in a balanced modulator, through the balanced modulator. CONSTITUTION:A voltage pulse 7 is applied to an input terminal 6. A voltage E1 in a horizontal scanning period genertes a difference between currents I1 and I2, and a signal is supplied equivalently to an input terminal 3 to generate B', thereby canceling A'. In a next horizontal scanning period, a voltage E2 having a difference from the mean voltage of the pulses 7 generates a difference between the currents I1 and I2 and a signal is supplied equivalently to the input terminal 3 to generate D', but the phase of a subcarrier applied to modulators 1 and 2 in the V-axis direction during the horizontal scanning period is inverted to generate the B' by the voltage E2 eventually, thereby canceling the A'. Thus, the subcarrier component induced externally on the V axis in the modulated modulator is canceled through the balanced modulator.
