Title: Torque boost controller for induction motor
Inventor: YAMADA KOJI
IPC: H02P27/06
Filed: 1993-11-30
Abstract: PURPOSE:To prevent concentration of current to a specific phase of main circuit in a voltage type inverter by outputting a torque boost voltage from an inverter where the detected value of output current is regulated within a predetermined design value of exciting current. CONSTITUTION:When a voltage.command value V' of an inverter output voltage commander 15 is increased by an increment AB from zero by a command delivered from a CPU 14 in a torque boost controller, output voltage V of a voltage type inverter 1 increases. The output current I follows up the increasing output voltage V and a detected value (i) of output current, i.e., an output current data d1 obtained by converting an output from an output current detector 11 through an A/D converter 13, also increases. On the other hand, an exciting current design data d2 sq. rt. 2 times as large as a predetermined exciting current i1 of a load induction motor is taken out from a memory 12. Subsequently, the CPU 14 compares the output current d1. with the exciting current design data d2 and further increases the torque boost value V' by an increment DELTAB if d1<d2. This constitution protects the inverting element in the main circuit against thermal damage.

Filed: 1991-11-15
Abstract: PURPOSE:To obtain the images free from ghost faults by using a horizontal PLL circuit to generates an auxiliary horizontal synchronizing signal from a burst PLL despite the malfunction of a horizontal synchronizing separator caused by the ghosts. CONSTITUTION:The horizontal synchronizing signal which is synchronously separated is inputted to a horizontal PLL circuit 17. The oscillation frequency of a VCO 23 of the circuit 17 is equal to 32 times as much as the horizontal scanning frequency fH. This clock is divided for generation of a horizontal reference signal FH and a burst gate pulse. The phase of the signal FH and the horizontal synchronizing signal are compared with each other for formation of a PLL. Then the color burst signal sampled by a burst sampling circuit 18 is amplified and inputted to a burst PLL circuit 20 based on a color burst signal. A VCO 27 of the circuit 20 generates the oscillation frequency of an integer multiple as much as a color subcarrier fSC. This clock is divided for generation of a reference signal fSC of the color subcarrier and an auxiliary horizontal synchronizing signal and then for production of a PLL with comparison of the phases.

Consequently, wall charges are generated on the respective electrodes. Then the voltages in the entire-surface writing process are made opposite in application polarity. Consequently, the wall surfaces accumulated on the maintenance electrodes X1 and scanning electrode Y1 are opposite in polarity from each other. In an address process, remaining wall charges having such a polarity that they are added to an address voltage applied between electrodes A1 and Y1 . Therefore, the voltage applied between the electrodes A1 and Y1 is never lowered under the influence of the residual charges and the address discharging can stably be performed.
