Deflection yokes

Radio and television uses largely arise from the ability to produce components with a high level of dimensional accuracy coupled with good dielectric properties, high heat distortion temperatures and the availability of selfextinguishing grades. Specific uses include coil formers, picture tube deflection yokes and insert card mountings.

In the electronics industry the advantages of higher electrical resistivity and lower cost of ceramic ferrites (M Fe 04) (p, 1081) over metallic magnets have been recognized since the 19.50s and the solV ferrites (M" = Mn, Znl are the most common of these. They are used on the sweep transformer and deflection yoke of a television set and, of course, Mn02, either natural or synthetic, is required in their production. 

In the last chapter, we presented a synopsis of the technological advances made in CRT s, particularly those for the color TV tube up to about the mld-1960 s. Since that time, a number of innovations have been accomplished. This change has been in response to market demand for a less bulky display device as well as a larger display size, i.e.- the "flat" television tube. Major improvements have been created in the electron gun, deflection yoke and the glass faceplate. What we are addressing is the changes in t rpe of display which has resulted. In the ordinary CRT of the... 

TV deflection yokes are used in display monitors to focus electrons through the interaction with a strong magnetic field, and create an image on the screen. The requirements for the ferrite element in yokes are similar to those for high-frequency transformers since the image resolution has a direct relation with the frequency needed in the horizontal scanning. A resolution of 2.5 x 10 pixels is achieved with a horizontal frequency of...

Applications for PPO resins include television and communication components such as terminal blocks and deflection yokes. Plumbing and automotive parts such as handles, vents, and brackets are a major end use. Housings, particularly those molded in the structural foam configurations, dominate the business machine and appliance market.

The junction region of the bulb of a CRT with the neck section is critical to the geometry of the device. Tubes made with these separate sections are intended for electromagnetic deflection, and this region is where the deflection yoke is located. 

All three beams are deflected simultaneously by a single large-diameter deflection yoke, which is usually permanently bonded to the CRT envelope by the tube manufacturer. The three phosphors together are designated P-22, individual phosphors of each color being denoted by the numbers P-22R, P-22G, and P-22B. Most color CRTs are constructed with rare-earth-element-activated phosphors, which offer superior color and brightness compared with previously used phosphors.

Many of the things that are used each day are bonded or assembled with adhesives, or sealed with sealants your table and ail the furniture, the foam cushioning of your seat, electronic parts in your computer, the double-insulated window, pressure-sensitive tapes and labels, your shoes, the food and other packaging, the carpet and floor coverings, the wallpaper, many parts in your car, many structures in airplanes, the PVC pipes in the kitchen, perhaps the tubes of your bicycle, the liner in some garments, shirt collars, the deflection yokes in your TV set, the metal base of electrical bulbs, children s toys, baby diapers and feminine napkins, and many other things — even this book It would take too much time to list everything.
