    • An improved deflecting yoke where the luster distortion in the case of high angle of view can be reduced and a display device which provides a high-quality screen, using this. For the deflecting yoke, the horizontal deflecting coil (2) has a pair of saddle-type coils made by winding conductors around, and at a part of the coil conductor which forms the transition part on the side of its fluorescent face, collar-shaped parts (2a) projecting outward and bents (2b) extending aslant to the side of an electron gun (9) from these collar-shaped parts (2a) are formed at the diagonal parts forming angles theta ranging from 48 DEG to 58 DEG with respect to the horizontal axis (24) on the plane constituting roughly right angles to the axis of a cathode ray tube. It becomes possible to correct luster distortion practically without deteriorating horizontal deflecton sensitiveness by the magnetic field generated by this collar-shaped part (2a) and the bent (2b).
    • 可以减少在高视角的情况下的光泽变形的改进的偏转轭,并且使用该显示装置提供高质量的屏幕。 对于偏转轭,水平偏转线圈(2)具有一对鞍形线圈,其通过在其荧光面侧面上形成过渡部分的线圈导体周围缠绕导体而形成匝形线圈, 形成向外突出的部分(2a)和从这些颈状部分(2a)向电子枪(9)侧倾斜延伸的弯曲部分(2b)形成在对角部分,形成角度θ为从48°至58°,相对于 在与垂直于阴极射线管轴线成直角的平面上的水平轴线(24)上。 可以通过由该环形部分(2a)和弯曲(2b)产生的磁场而不会使水平偏转敏感性恶化,实际上校正光泽失真。

    • Communication equipment and a communication system whose noise immunity can be improved even in the case of a short key-code length (inclusive of the case where diffusion of a spectrum is not effected). A series of digital information containing binary information composed of 1 and -1 is set to b(j) with j being an integer. On the transmitting side, multiplication output of n (n=3 or more) partial series are serially transmitted either directly or after being modulated, while on the receiving side, the received signals are demodulated if they are modulated, and the signals corresponding to the n partial series are serially multiplied so as to reproduce the digital information series corresponding to the original values of 1 and -1. Furthermore, digital information is reproduced from that information. Synchronous reproduction means on the receiving side of a spectrum diffusion communication system multiples all the signals from time T to (n - 1)T by the present signal, where T is the information bit interval and n is 2 or greater, and the product signal is multiplied by itself to reproduce the synchronizing signal.
    • 通信设备和即使在短键码长度(包括不影响光谱扩散的情况下)的情况下也可以提高其抗噪声性的通信系统。 包含由1和-1组成的二进制信息的一系列数字信息被设置为b(j),其中j是整数。 在发送侧,n(n = 3以上)部分序列的乘法输出直接或调制后串行发送,而在接收侧,如果接收信号被调制,则对其进行解调, n部分序列被连续地相乘以再现与原始值1和-1对应的数字信息序列。 此外,从该信息再现数字信息。 在频谱扩散通信系统的接收侧的同步再现装置将来自时间T到(n-1)T的所有信号乘以当前信号,其中T是信息比特间隔,n是2或更大,乘积信号 被自身相乘以再现同步信号。

    • IT IS AN OBJECT TO PERFORM A THIN AND COMPACT DESIGN OF THE OBJECTIVE LENS DRIVING DEVICE. IN ORDER TO ACHIEVE THE ABOVE OBJECT, OPTICAL BEAM (8) IS PASSED THROUGH A SPACE SURROUNDED BY A TRACKING COIL (4) AND A FOCUSING COIL (5) WHICH ARE ADJACENT TO EACH OTHER AND FIXED IN A HOLDER. FURTHER, IT IS ANOTHER OBJECT TO POSITION THE OBJECTIVE LENS WITH HIGH PRECISION IN AN OBJECTIVE LENS DRIVING DEVICE FOR SWITCHING A PLURALITY OF OBJECTIVE LENSES (7-1,7-2) IN ACCORDANCE WITH TYPE OF AN OPTICAL DISC. IN ORDER TO ACHIEVE THIS OBJECT, MAGNETIC SUBSTANCES WHICH ARE RADIALLY EXTENDED WITH THE SLIDING SHAFT (6) AT THE CENTER ARE PROVIDED IN THE LENS HOLDER (3), AND THE MAGNETIC SUBSTANCES (12) ARE LOCATED WITHIN A PLANE PERPENDICULAR TO THE PLANE CONSTITUTING THE MAGNETIC GAP AND AT THE OUTSIDE OF THE MAGNETIC GAP. STILL FURTHER, IN AN OBJECTIVE LENS DRIVING DEVICE IT IS ANOTHER OBJECT TO PREVENT THE OCCURENCE OF POSITIONAL DISPLACEMENT OF THE OBJECTIVE LENS (7) DUE TO RESISTANCE FORCE OF CURRENT SUPPLY MEANS SUCH AS FPC. TO ACHIEVE THIS OBJECT, A FIRST OBJECTIVE LENS (7-1) AND A SECOND OBJECTIVE LENS (7-2) ARE ARRANGED SO THAT THE OBJECTIVE LENS ARRANGEMENT ANGLE AT WHICH THE FIRST AND SECOND OBJECTIVE LENSES (7-1,7-2) ARE ARRANGED WITH RESPECT TO THE SHAFT CENTER OF THE SLIDING SHAFT (6) IS DISPLACED, BY A PREDETERMINED AMOUNT, FROM THE MAGNETIC CIRCUIT (1,2,9) ARRANGEMENT ANGLE AT WHICH THE MAGNETIC SUBSTANCES AND THE MAGNETS (2) ARE ARRANGED WITH RESPECT TO THE SHAFT CENTER OF THE SLIDING SHAFT (6).
