Latest Patents

One of Archer's latest patents is the "Television raster pincushion distortion correction device." This invention addresses the issue of stray fields generated by vertical deflection coils in television receivers. The deflection yoke incorporates magnetically permeable field forming members that utilize these stray fields to create an electromagnetic field, aiding in side pincushion distortion correction. The design includes flux gathering portions that follow the contour of the yoke core, effectively reducing the undesirable effects of the stray field.

Another significant patent is the "Deflection yoke incorporating a permeable corrector." This invention is part of a color television display system and features a magnetically permeable ring positioned at the rear of the yoke around the kinescope's neck. The ring is designed with slots that separate it into two semi-circular segments, allowing external flux from the deflection yoke coils to be shunted into the corrector. This innovation improves beam focus and reduces vertical coma error, enhancing the overall performance of the television display.
