Abstract: The system compensates for an absence of a reproduced signal in one channel with a portion of a reproduced signal in another channel. The compensating signal contains its information which is interrelated with that of the signal absence portion. The compensation is performed by a switching pulse having its width corresponding to an interval of the signal absence portion.

CPC classification number: H02K37/22
Abstract: A digital rotation or stepping motor contains oil of suitable viscosity which fills the space between a rotor and a stator. The motor is digitally and intermittently stepped in response to input pulses. The viscosity of the oil is selected to prevent a hunting which might otherwise be produced when the rotor stops its intermittent rotation.

Abstract: This is a system for magnetically recording and playing back video signals on a rotating disc-shaped or drum-shaped magnetic medium. A plurality of magnetic heads move alternately and intermittently in a predetermined cycle. The invention permits detection of feed initiation positions, feed completion positions, feed burst positions and feed reset positions of the magnetic heads.

Abstract: A magnetic tape recorder for television video signals uses two sequentially active magnetic heads mounted on a revolving disk. A commutator is arranged to rotate in synchronism with the revolving disk and to act as a program switch for selecting the magnetic head switching points and for controlling the associated circuitry. The program selectively changes the instantaneous electrical characteristics of a path leading from the heads to the associated circuitry, these changes occurring as a function of whether one or two heads is operative at the instant of change.
Abstract translation: 用于电视视频信号的磁带录像机使用安装在旋转盘上的两个顺序有效的磁头。 换向器被布置为与旋转盘同步旋转，并且用作用于选择磁头切换点并用于控制相关电路的程序开关。 该程序选择性地改变从磁头引导到相关联的电路的路径的瞬时电特性，这些变化作为一个或两个磁头在变化时刻是否起作用的功能而发生。

Abstract: A signal address system is adapted for use with apparatus for magnetically recording and reproducing a signal on a rotary member. At least one magnetic head is provided for recording and reproducing a video signal on a rotating magnetic member. The head is moved by drive pulses associated with field signals or frame signals of the video signal. Thus, the number of drive pulses may be used to provide an output signal representing the total number of drive pulses, which is substantially equivalent to an address signal. Thus, an address may be called out without requiring the recording and reproduction of a specific address signal on the magnetic medium.
Abstract translation: 信号地址系统适用于在旋转构件上用于磁记录和再现信号的装置。 提供至少一个磁头用于在旋转的磁性构件上记录和再现视频信号。 头部由与视频信号的场信号或帧信号相关联的驱动脉冲移动。 因此，可以使用驱动脉冲的数量来提供表示驱动脉冲总数的输出信号，其基本上等于地址信号。 因此，可以调用地址，而不需要在磁介质上记录和再现特定的地址信号。
