Abstract: In one embodiment, a fluorescent lamp dimming circuit includes power factor correction control, dimming control, and switching devices. The power factor correction control may be connected to power factor correction circuitry that produces a regulated DC buss. The dimming control circuit may be connected to the input of the fluorescent lamp dimming circuit for producing a driver signal whose frequency varies depending on the input voltage waveform perhaps as modified by a dimmer. The control circuit may produce a drive signal with a duty cycle profile to drive switching devices. The switching devices invert the DC buss voltage to an AC voltage waveform for driving a resonant tank circuit. The resonant tank circuit may include an inductance, a capacitance, and the impedance of a fluorescent lamp. The AC voltage waveform when applied to the resonant tank circuit may cause the fluorescent lamp to dim based on the dimmer setting.

Abstract: Based on designs concerning boron nitride thin-films each including boron nitride crystals in acute-ended shapes excellent in field electron emission properties, and designs of emitters adopting such thin-films, it is aimed at appropriately controlling a distribution state of such crystals to thereby provide an emitter having an excellent efficiency and thus requiring only a lower threshold electric field for electron emission. In a design of a boron nitride thin-film emitter comprising crystals that are each represented by a general formula BN, that each include sp3 bonded boron nitride, sp2 bonded boron nitride, or a mixture thereof, and that each exhibit an acute-ended shape excellent in field electron emission property; there is controlled an angle of a substrate relative to a reaction gas flow upon deposition of the emitter from a vapor phase, thereby controlling a distribution state of the crystals over a surface of the thin-film.

Abstract: A high impedance plasma opening switch having an anode and a cathode and at least one additional electrode placed between the anode and cathode. The presence of the additional electrodes leads to the creation of additional plasma gaps which are in series, increasing the net impedance of the switch. An equivalent effect can be obtained by using two or more conventional plasma switches with their plasma gaps wired in series. Higher impedance switches can provide high current and voltage to higher impedance loads such as plasma radiation sources.

Abstract: Beam control pulse modulation in an RF transmitter tube is provided by a solid state switch connected between the cathode power supply and the cathode of the transmitter tube. The beam controlling element is returned to the normal cathode power source such that closing the switch between the cathode and the cathode power source brings the beam controlling element voltage to cathode potential causing beam current to flow, while opening the switch provides a very high equivalent cathode resistance, which self-biases the tube in the cutoff region, eliminating the need for a separate "off" voltage power supply. Off-edge performance may be further improved by providing an off switch connected between the cathode and a collector tap on the cathode power supply, and closing the switch when the on switch is opened to accelerate return of the cathode potential to the cutoff voltage.
