Title: Protection of inverter
Inventor: TATEISHI HIDEKI
IPC: H02M7/48
Filed: 1994-08-05
Abstract: PURPOSE:To prevent the occurrence of a stall during the operation of an inverter by setting the lower limit of an output frequency when reducing the output frequency of the inverter. CONSTITUTION:When a current feedback signal Irb is smaller than a stall level, an output frequency f0 is converted to an output frequency f1 by means of a frequency calculating circuit 10. When the current feedback signal Irb is larger than the stall level, the output of a comparator 12 is multiplied by a gain coefficient by means of a multiplier 11 and the obtained value is subtracted from the frequency command f0 as a means for preventing a stall. Therefore, the output frequency f1 of the frequency calculating circuit 10 will go on dropping until the anti-stall operation is cancelled. When the output frequency f1 will go down across the lower limit, an 'a' contact 8 is turned off and a 'b' contact is turned off by a comparator 7 and the output frequency f1 is clamped at the lower limit. By this method, such troubles can be prevented that depending on loads, motor current is not reduced even when a frequency is reduced or a motor is kept stopping when a main body of an inverter device has a trouble.

Abstract: PURPOSE:To prevent dips from being produced in an AC input voltage waveform of the related rectification means by specifying inductance value of DC reactor for smoothing which is provided at a DC output side of a rectification means for turning this DC reactor flowing current into interrupted state. CONSTITUTION:When an AC input voltage of a thyristor rectifier 4 is set to E, a DC output current of this thyristor rectifier 4 is set to ID, and a proportional constant is set to KP, the DC output current ID becomes interrupted if an inductance value L of a DC side circuit which is represented by a DC reactor 5L of this thyristor rectifier 4 satisfies L<=KrE/ID). Thus, no dips are produced in the AC voltage waveform without producing line short-circuiting in commutation. Inferior influence to an AC power supply or a load which is connected to this AC power supply can be avoided.

Title: Communication system and receiver
Inventor: MATSUDA NOBUHIRO
IPC: H04N21/44
Filed: 1994-08-30
Abstract: PURPOSE: To eliminate time lags between conversations as much as possible by performing delay so as to match the output timings of respective pieces of medium information when the deviation of reception time between the respective pieces of the medium information is at a level for making a user feel uneasy but outputting the respective pieces of the medium information as they are when the deviation is at the level for not making the user feel uneasy. CONSTITUTION: A time information comparison part 94 inputs the time deviation of the arrival time of frames relating to video images and the arrival time of the frames relating to sound. When the time deviation is larger than a fixed value, delay control for matching the output timings is performed by a first delay circuit 95 and a second delay circuit 96. Also, when the deviation is less than the fixed value, the output of a first decoding part 92 and a second decoding part 93 is outputted as is without performing the delay control. Thus, while eliminating reproduction deviation between the medium information as much as possible, the time lags generated at the boundary of the conversations are eliminated as much as possible.
