(under subclass 399) Subject matter wherein the electrical circuit connected to the deflection coil includes a solid state switching device.
(1) Note. A solid-state switching device is a semiconductor which may be a diode or a multielectrode element such as a silicon controlled rectifier, a silicon controlled switch, or a four-layer Shockley diode wherein no amplification of the current takes place in passing through the switching device to the deflection coil.
(2) Note. The combination of a deflection circuit including the switching device and a power supply energized from the deflection circuit is also in this subclass.
