Title: Controller for motor and variable-speed generator
Inventor: FUTAMI MOTOO
IPC: H02P27/05
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To minimize the influence of the negative-phase-sequence components of primary voltage, by converting the negative-phase-sequence components in the primary-side voltage of a motor into secondary-side alternating-current part, and superposing the secondary-side alternating-current part on the alternating-current voltage applied from the secondary side as high-frequency voltage. SOLUTION: The voltage vector of the negative-phase-sequence components in the primary- side voltage of a motor 9 is detected using a negative-phase-sequence component detector 1. The phase of the negative-phase-sequence voltage components is detected through a negative- phase-sequence voltage phase detector 15. A secondary induced voltage converter 2 detects the induced voltage, corresponding to the negative-phase-sequence components in the voltage, and a compensating voltage generator 3 creates a voltage command to a frequency converter 8, so as to cancel out the induced voltage.  A compensating phase detector 16 detects the rotor-side phase of the negativephase-sequence voltage from slip phase and negative-phase- sequence voltage phase, and a three-phase converter 4 divides the negative-phase-sequence compensating voltage into three phases to create a voltage command correction value. Since compensation can be made before a current due to the induced voltage starts to flow, therefore, it is possible to eliminate the effects of the negative-phase-sequence components without phase delay.

Title: Stabilized voltage controlled oscillator
Inventor: TAKAUCHI RYUJI
IPC: H03L1/02
Filed: 1988-08-02
Abstract: PURPOSE:To prevent an influence due to a leading-in phenomenon and to stabilize a frequency by providing first and second voltage controlled oscillators, and suppressing fluctuation of the oscillatiion central frequency of the first oscillator on the basis of the fluctuation part of an oscillating frequency to be obtained with a phase comparing means. CONSTITUTION:A second voltage controlled oscillator(VCO)3 is operated by a timer circuit 4 in each prescribed time. In each prescribed time, the oscillation part of the oscillation central frequency of the VCO3 is obtained by a phase comparing means 5 and this fluctuation part is defined as a direct current voltage  V by an LPF6 and held by a hold circuit 8 for a prescribed time. Since the fluctuation part  V can be regarded as the oscillation part of the central frequency of the VCO2, it is added through an LPF9 to the input signal of the VCO2. Thus, the oscillation centrol frequency of the VCO2 is exactly controlled samelly as the input signal and oscillation fluctuation at the time of inputting power source or converting temperature can be suppressed. Since the fluctuation part of the frequency is obtained in each prescribed time, the influence of leading-in phenomenon can be prevented between the both VCOs.

Title: Horizontal defiecting circuit
Inventor: TAKAHASHI ATSUSHI
IPC: H04N5/12
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a horizontal deflecting circuit which can stabilize the circuit without providing a correcting circuit, necessitates no adjustment, and has high accuracy, by comparing the frequencies or phases of a horizontal synchronizing signal input and a horizontal output pulse, and controlling a voltage control oscillator, based on its compared output. CONSTITUTION:As for a horizontal synchronizing signal (frequency fy) which has been inputted, and a waveform-shaped horizontal output pulse (frequency fv) being an output of a waveform shaping circuit 11, a difference of frequencies and phases is detected by a phase comparing detector 2. When a difference of phases or phases exists between both of them, an error signal E0 is outputted from the phase comparing detector 2. An operation of a PLL is controlled so that its error signal E0 becomes zero. The error signal E0 is converted to a DC voltage VD by an integrator 3, and varies an output frequency f0 of a voltage control oscillator 4. An output of the f0 is waveform-shaped by the waveform shaping circuit 11 and becomes the fv, but as a result of execution of the PLL operation, the fv draws nearer to the fy. Thereafter, after the same operation is repeated, the loop is balanced in a stable state.
