    • In a device for reproducing the information, especially the video signal optically, magnetically or otherwise recorded on the spiral or concentric track on a disk-shaped recording medium, a control system for controlling the radially inward or outward shift or jump of a reproduction transducer from one track to another for effecting, in addition to the normal reproduction, the special effect reproductions such as still picture, slow, fast and reverse motions. The control system comprising a shifting means for shifting or jumping the transducer in the radial directions substantially perpendicular to the tracks, a control means for maintaining the transducer to scan the desired track, and a detecting means for detecting whether or not the transducer has been shifted or jumped and brought to the desired track and generating the output signal in response to which the shifting means is disabled to decelerate and stop the shifting or jumping of the transducer.

    • A tracking control system for a magnetic video recording and reproducing system, in which a signal is recorded on a magnetic tape as record tracks at an angle with respect to the longitudinal direction of the tape and is reproduced therefrom by rotary magnetic heads. At the time of start of playback, the relative phase of scanning tracks of the rotary heads and the afore-said record tracks is automatically varied at a predetermined cycle. During the period of this variation, a phase position at which a maximum value of the level of the reproduced signal from the rotary heads is detected, and the phase variation is stopped at the detected phase position so as to let the scanning tracks of the rotary heads coincide with the record tracks.
    • 一种用于磁性视频记录和再现系统的跟踪控制系统,其中信号被记录在磁带上,作为相对于磁带的纵向成角度成一定角度的记录磁迹,并通过旋转磁头再现。 在开始播放时,旋转磁头和上述记录磁道的扫描轨迹的相对相位以预定的周期自动变化。 在该变化期间,检测来自旋转磁头的重放信号的电平的最大值的相位位置,并且相位变化在检测到的相位位置处停止,以便使旋转磁头的扫描轨迹 头部与记录轨迹相吻合。

    • The first basic structure of the electron emission element of the present invention, includes at least two electrodes disposed in a horizontal direction at a predetermined interval, and a plurality of electron emission portions made of a particle or an aggregate of the particles dispersively disposed between the electrodes. On the other hand, the second basic structure of the electron emission element of the present invention includes at least two electrodes disposed at a predetermined interval, a conductive layer disposed between the electrodes so as to be electrically connected thereto, and a plurality of electron emission portions made of a particle or an aggregate of the particles dispersively disposed on the surface of the conductive layer between the electrodes. According to these structures, an electron emission element with high stability can be obtained, in which emissions can be emitted efficiently and uniformly even in the absence of a bias voltage (electric field) from outside in an output (emission) direction of the electrons, by utilizing a transverse electric field generated between the electrodes disposed in a horizontal direction at a predetermined interval or an in-plane electric current flowing through the conductive layer disposed between the electrodes.
