Latest Patents
One of Fastenau's latest patents is a method of manufacturing a color display tube that utilizes a magnetic quadrupole post-focusing mask. This innovative method involves magnetizing the mask using soft iron or its magnetic equivalent, which is shaped to create raised portions. These portions are subjected to a strong external magnetic field, allowing for the entire area of the mask sheet to be magnetized in a single operation. This technique is particularly beneficial for producing masks for small tubes and high-definition tubes.
Another significant patent is for a cathode ray tube that features a magnetic focusing lens. This monochrome cathode ray tube includes an electromagnetic deflection unit and an integrated focusing multipole correction unit. This unit generates both a static focusing field and higher-order multipole correction fields to address spot distortion errors, particularly astigmatism.
