A cathode ray tube device increases image resolution using spatial or temporal techniques. The method includes an improved processing sequence and cleaning method where residue formed from processing a previous substrate are cleaned by the etching process used to remove an exposed layer of material from the present substrate. The program upgrading method can perform program upgrading through a PCMCIA interface easily. Event records are created for the subset of events. The invention further relates to hybrid soybean seeds, plants and plant parts produced by crossing the cultivar 3235020 with another soybean cultivar.
