A description is given of the main electron-optical, electrical, and mechanical features of the deflection yoke that provides automatic convergence in the 20AX system. Sectionally wound saddle coils are used, and the shells in which they are mounted incorporate reference pieces to minimize assembly tolerances. An easy to operate assembly of multi-pole magnet rings provides for static convergence, color purity, and raster symmetry adjustment.

This paper presents the results of an investigation into electronic circuitry and techniques to replace the electromechanical switches and potentiometers currently used in consumer audio equipment. Particular attention was devoted to the development of a touch sensor which is reliable and insensitive to electrical initerference. The logic circuitry was developed with standard CMOS integrated circuits to perform the interlock and memory functions provided by electromechaiiical controls.

In this report the causes for luminance dependent distortions which are produced from the detection of television signals will be discussed and possibilities for improvement will be shown. Due to the availability of measurement equipment all test are performed in the CCIR-standard. The result can unconditionally be transferred to the NTSC-standard.

Recently, several new approaches to the design of television tuning systems have emerged. Federal regulations concerning equal parity for UHF and VHF tuning systems have caused increased interest in purely electronic tuning systems. In addition, such factors as reliability, economics, aesthetics and convenience, as well as the increased number of channels on UHF and cable, have spurred interest in the development of solid state, totally electronic television tuning capability. The ideal tuning system incorporates all of these features.

The 20AX system was recently introduced in Europe as the first self converging picture tube/deflection coil, combination for 110°deflection and screen sizes up to 26". The system is based on the automatic convergence principle discovered by Haantjes and Lubben of Philips Research Laboratory more than 20 years ago. It makes use of an in-line gun array in conjunction with a specially designed saddle type deflection coil. Residual small tolerance errors are compensated by a simple dynamic four-pole system. The tube is 2 cm shorter than conventional 110°tubes and has a standard 36.5 mm neck in order to obtain good color selection. A slotted mask is used in combination with a stripe-structure screen. Picture sharpness is ensured by an astigmatic electron gun.

This paper describes a unique circuit called a dual timer. The circuit was designed to be versatile and universal in consumer electronics applications. The circuit can operate in monostable as well as astable mode. This circuit can be used not only in linear circuitry but in digital circuitry as well since it operates from 5 volts to 15 volts and its output is TTL compatible. Each timer is basically comprised of two comparators (one for trigger and one for threshold, refer to Figure 1) a flip flop and a totem-pole output stage.
