摘要： A video data is accompanied or multiplexed with one or more flags indicating a relation between fields or frames of video data for transmission or recording. An interlace flag determines whether the video data is interlaced or not. A still image flag determines whether the video data carries a motion image, a field still image, or a frame still image. A frame change flag determines whether or not a given frame of the still image is identical to its previous frame. At least one of the three different flags is multiplexed with its relevant video data.

摘要： FET power transistors of a power supplying part execute high-frequency switching operation and form current paths to three-phase windings. A voltage detecting part compares terminal voltages of the three-phase windings and produces a detected pulse signal in response to a comparison result. A state shifting part and an activation control part control active periods of the FET power transistors in response to the detected pulse signal. A commanding part produces a command signal in response to an output pulse signal of the voltage detecting means. A switching operation block produces a switching pulse signal in response to a comparison result of a current-detection signal with the command signal, and causes at least an FET power transistor of the power supplying part to perform high-frequency switching in response to the switching pulse signal. The state shifting part produces a timing signal after an adjust time from the detection of the detected pulse signal and shift-holds a holding state in response to the timing signal. The state shifting part changes the adjust time smaller in case that the command signal is larger than a predetermined value, thereby making the product value of the adjust time and the rotational speed smaller in the case.

摘要： First power transistors of first power amplifying parts and second power transistors of second power amplifying parts form current paths from a DC power source to three-phase windings. A first distribution control block activates the first power amplifying parts with first three-phase signals, each having an active electrical angle larger than 120 degrees. A second distribution control block activates the second power amplifying parts with second three-phase signals, each having an active electrical angle larger than 120 degrees. A switching operation block has a current detecting part and a switching control part. The current detecting part obtains a current detected signal corresponding to a composed supply current of negative or positive parts of the three-phase drive currents to the three-phase windings. The switching control part compares an output signal of the current detecting part with a command signal and switches at least one power transistor of the first power transistors and the second power transistors to an off state when the output signal of the current detecting part becomes a value corresponding to the command signal, thereby causing the at least one power transistor to perform high-frequency switching responding with a comparison result.

摘要： In a brushless motor having a field permanent-magnet part, an altering signal producing circuit produces altering signals which vary analogously with output signals of a position detector. Then, at least one distributing circuit distributes current to first and/or second three-phase distributed current signals which vary analogously with the output signals of the altering signals. The first and/or second distributed current signals may be composed by a distributing composer to produce three-phase distributed signals. A driving block uses the three-phase distributed signals to produce driving signals for the three-phase coils.

摘要： As shown in FIG. 9, a switching control part 310 detects voltage drops of FET power transistors 81 to 83, and outputs a switching control signal Vd responding with a modulated signal changed in synchronization with a movement of a motor, and a detected operation voltage. The switching operation of a switching transistor 61 is controlled responding with the switching control signal Vd, so that a converted DC voltage of a voltage converting part 52 is controlled. The converted DC voltage of the voltage converting part is supplied to power amplifying parts 11 to 17. The power amplifying parts configured by FET power current-mirror circuits analoguely alter current paths from the converted DC voltage of the voltage converting part to three-phase windings 2, 3, and 4, whereby pulsation of drive currents I1, I2, and I3 to the windings is reduced and a motor vibration is decreased in level.
