摘要： A cathode ray tube device capable of providing sufficient shielding effect against leaking alternating electric field while exhibiting high reliability during long use. Alternating electric field generated by a deflection yoke is sufficiently reduced by the shielding effect produced by a conductive film formed on a funnel portion. A gap formed between the conductive film and an insulating sheet provided between the conductive film and the deflection yoke, due to dimensional error, is filled with insulating silicone grease, so as to avoid secular degradation of insulation which otherwise may occur due to accumulation of dust and other matters.

摘要： A deflection yoke for use with cathode ray tubes of the type in which one or more electron beams generated therein are deflected includes a magnetic core member and a selected wire winding thereon to produce a magnetic field for deflecting the beam. Each core has a winding axis defined thereon and each winding occurs along at least one segment having a given length along the winding axis. Each segment has a first end and an opposed second end and a middle portion defined therebetween. The winding pattern of each winding in accordance with the invention begins in the central portion of each segment and includes a first toroidal winding portion starting at this midpoint and extending in a first handed direction to a first segment end. The winding pattern includes an intermediate transition portion which extends from the first segment end to the second segment end. The winding pattern continues with a second toroidal winding portion extending from the second segment and to the middle starting point. It has now been discovered that by providing a conductive wire winding on the ferrite core which follows a helical path about a winding axis along the core, and which follows a winding pattern beginning in the middle portion of each winding segment and which is laid up to intentionally include certain wire crossovers, an improved CRT display raster characterized by reduced distortion and reduced ringing is provided.

摘要： A horizontal deflection circuit for a CRT supplies an exciting current in such a way that flyback voltages including both a positive voltage and a negative voltage as components are generated in horizontal deflection coils of a horizontal deflection yoke, respectively, during energizing the horizontal deflection yoke to provide a magnetic field for horizontal scans. A positive electric field of VLF and a negative electric field of VLF which are generated in the horizontal deflection yoke by the respective flyback voltages cancel each other to decrease a composite electric field of VLF emitted from the horizontal deflection yoke. This prevents unwanted radiation leaking to the outside of the a CRT display.

摘要： An electron gun for a cathode ray tube (CRT) includes a cathode, a low voltage beam forming region (BFR), and a high voltage deflection focus lens disposed in the beam deflection region of the CRT's yoke for simultaneous focusing and deflection of the electron beam on the CRT's display screen. The deflection lens includes a first electrode either in the form of a cylindrical metal grid or a conductive coating disposed on the inner surface of the CRT's neck portion and extending into the magnetic deflection field. The deflection lens further includes a second electrode disposed either on or immediately adjacent to the inner surface of the CRT's frusto-conical funnel portion intermediate the magnetic deflection yoke and the CRT's display screen. By positioning the CRT's focus lens within the deflection field, the deflection center of the beam is disposed within the focal point of the focus lens permitting the focus lens to operate as a deflection lens to not only focus the beam, but also increase beam deflection sensitivity. The coincidence of the beam focus and deflection regions reduces beam "throw distance" (field-free zone) resulting in a corresponding reduction in beam magnification and space charge effect and improved beam spot on the CRT's display screen. Positioning a focus electrode on the CRT's neck or funnel portion increases the equivalent diameter of the main focus lens which reduces the lens spherical aberration effect on the beam, while co-locating the beam focus and deflection regions also allows for shorter CRT length.
摘要翻译：用于阴极射线管（CRT）的电子枪包括阴极，低电压波束形成区（BFR）和设置在CRT轭的光束偏转区域中的高电压偏转聚焦透镜，用于同时聚焦和偏转电子在CRT的显示屏上。偏转透镜包括呈圆柱形金属格栅形式的第一电极或设置在CRT颈部的内表面上并延伸到磁偏转场中的导电涂层。偏转透镜还包括设置在CRT的截头圆锥形漏斗部分的内表面上或紧邻CRT偏转线圈和CRT显示屏之间的第二电极。通过将CRT的聚焦透镜定位在偏转场内，光束的偏转中心设置在聚焦透镜的焦点内，允许聚焦透镜作为偏转透镜工作，不仅聚焦光束，而且增加光束偏转灵敏度。光束聚焦和偏转区域的重合减少了光束“投射距离”（无场区），导致光束放大率和空间电荷效应的相应减小以及CRT显示屏幕上改善的光束点。将聚焦电极定位在CRT的颈部或漏斗部分上增加了主聚焦透镜的等效直径，这减小了对光束的透镜球面像差效应，而同时定位光束聚焦和偏转区域也允许较短的CRT长度。

摘要： A multiple frequency horizontal scan system includes a scan frequency compensation system which detects horizontal scan frequency changes by frequency detecting the horizontal sync pulses. A frequency responsive switching system couples the appropriate reactive components to the horizontal defection yoke and horizontal output transformer in response to sync pulse frequency. The system further supplies alternative voltages for the scan system operating supply in response to horizontal sync pulse frequency. In addition, the system provides a convenient source of frequency dependent switching signal which may be utilized to operate additional auxiliary elements in response to changes of horizontal scan system frequency.
