Abstract:
Electromechanical systems using magnetic fields to induce eddy currents and generate lift are described. Magnet configurations which can be employed in the systems are illustrated. The magnet configuration can be used to generate lift and/or thrust. Lift and thrust predictions for various magnet configurations are provided. Arrangements of hover engines, which can employ the magnet configurations, and an associated guidance, navigation and control system, are described. Finally, a number of different applications, such as trains, elevators and printing, which utilize embodiments of the electromechanical systems described herein, are presented.
Abstract:
The present invention discloses a field emission type cold cathode incorporated device, which comprises a field emission type cold cathode having a number of electron emitting sections, said sections having sharp projections, and a vacuum tank for placing the field emission type cold cathode in a vacuum environment. In this device, a partial pressure of particular noble gas in residual gas contained in the vacuum tank is set equal to or lower than C/I (C is a constant and I is a maximum emission current value per one of the number of electron emitting sections during driving of the field emission type cold cathode). Also, in order to set a partial pressure of the particular noble gas in the residual gas contained in the vacuum tank equal to C/I (C: constant) or lower, a partial pressure of the particular residual gas in the vacuum tank is monitored by a mass analyzer during vacuum tank exhaustion.
Abstract:
The apparatus is comprised of a circuit wherein an alternating current input is connected in series to a lighting lamp or resistor, or other specific use, which produces a residual consumption, and a rectifier or sets of rectifiers which are also connected in series to said circuit and have outputs of direct current switched to the charger, which may also be used as lamp, resistor, etc., at the same time as the charge is effected or without the charge being effected. Application to the recharging of storage batteries in household appliances and/or other electric apparatuses.
Abstract:
An ion source that may be used to introduce a dopant material into the arc chamber is disclosed. A component containing the dopant material is disposed in the path of an etching gas, which also enters the arc chamber. In some embodiments, the dopant material is in liquid form, and the etching gas travels through the liquid. In other embodiments, the dopant material is a solid material. In some embodiments, the solid material is formed as a porous structure, such that the etching gas flows through the solid material. In other embodiments, one or more components of the ion source are manufactured using a material that includes the dopant material, such that the etching gas etches the component to release the dopant material.
Abstract:
A method of processing an optical device is provided, including: positioning an optical device on a substrate support in an interior volume of a process chamber, the optical device including an optical device substrate and a plurality of optical device structures formed over the optical device substrate, each optical device structure including a bulk region formed of silicon carbide and one or more surface regions formed of silicon oxycarbide. The method further includes providing one or more process gases to the interior volume of the process chamber, and generating a plasma of the one or more process gases in the interior volume for a first time period when the optical device is on the substrate support, and stopping the plasma after the first time period. A carbon content of the one or more surface regions of each optical device structure is reduced by at least 50% by the plasma.
