摘要： This invention relates to a rotational speed control system including a plurality of motor drivers for driving motors, and the object thereof is to drive a plurality of motors at the same rotational speed without depending on the number of motor drivers and without depending on the characteristics of each motor driver. A remote controller 31 and a motor driver 202 are connected to a motor driver 201. The motor drivers 201 and 202 control motors M11 and M12 at a prescribed rotational speed, respectively. A rotational speed instructing signal 91 indicative of the rotational speed is supplied from the remote controller 31 to the motor driver 201, and further supplied from the motor driver 201 to the motor driver 202. Because the rotational speed instructing signal 91 indicates a rotational speed which is transmitted in a digital value between the motor drivers 201 and 202, both of the motors M11 and M12 are driven at the rotational speed indicated by the rotational speed instructing signal 91.

摘要： A video signal reproduction apparatus with time base error correction and synchronization correction. The synchronization correction circuit is used only where the condition of the recorded video signal is such that synchronization correction is necessary. The latter circuit includes an image memory for storing a field of video data. The video data input to the image memory is at a relatively low data rate to enable use of a relatively low capacity image memory.

摘要： Method and system for phase comparison which uses a ramp-form signal generated from a reference frequency signal and a sampling pulse train signal synchronized with an input signal whose phase change is to be detected. The reference frequency signal, through a dividing circuit is normally utilized for generating the ramp-form signal while a shift pulse signal is generated when a phase of the sampling pulse train signal is deviated outside a predetermined section of each ramp portion of the ramp-form signal, and utilized for generating the ramp-form signal. By this feature, sampling times of the ramp-form signal are always maintained within the predetermined section of each ramp portion of the ramp-form signal even if a frequency of the input signal deviates very widely from the frequency of the reference frequency signal.

摘要： A device for controlling recording track jump operations includes a tracking servo loop which is activated when a data detecting point is traversed from an initial recording track on a recording disk to a target recording track. Circuitry is provided for accurate compensation in the event of overshooting the target recording track. A jump signal generating circuit may also be provided to reduce the frequency of generated traverse signals from a first frequency level to a second, lower frequency level when the data detecting point is a selected number of recording tracks away from the target recording track, or to gradually reduce the speed which the data detecting point traverses the recording tracks as the data detecting point moves from the initial recording track to the target recording track.

摘要： A pick-up positioning apparatus for a recording disc playback apparatus such as a video disc player, comprising a control circuit, a memory circuit, a scanning mechanism for moving the pick-up of the playback apparatus along a radius of a recording disc mounted on the playback apparatus, and pick-up sensing circuit for producing signals to indicate the current pick-up position along that radial direction. When a disc is first set on the playback apparatus, the scanning mechanism moves the pick-up along the radial direction to thereby successively read out a number of addresses recorded on the disc, which are stored in the memory circuit together with corresponding position data. Subsequently, to search for a specified address position on the disc, the address stored in the memory circuit which is closest to the specified address is read out and the corresponding stored position data is used in moving the pick-up close to the specified address position.
