    摘要: A getter device comprises a getter metal vapor releasing material and a source of an alkali metal which releases an alkali metal during or after the latter period of getter metal evaporation. Such getter devices are found to produce less methane after evaporation of the getter metal without producing higher hydrocarbons. A higher pressure of hydrogen is formed which aids cathode functioning.

    摘要: A Field Emitter Device (FED) having a substantially reducing atmosphere is described. The atmosphere in a FED can be maintained substantially free of oxidizing gases and includes a partial pressure of hydrogen between about 1.times.10.sup.-7 millibar (mbar) and 1.times.10.sup.-3 mbar. In one embodiment, a non-evaporable getter material previously charged with hydrogen gas is placed inside the FED before the FED is sealed. The non-evaporable getter material can be charged by exposure to hydrogen gas at a pressure between about 1.times.10.sup.-4 and about 2 bar. Subsequently, the components forming the FED are sealed, and the FED is evacuated and hermetically sealed to the outside atmosphere.

    摘要: A Voltage Converting LED Circuit with Switched Capacitor Network contains a 2-way MOSFET switch that connects a capacitor network to the output of an error amplifier, thereby enabling the error amplifier to resume operation quickly after the off-time segment of a PWM cycle. The switch is controlled synchronously with current sinks controlling brightness and color levels. In a preferred embodiment, multiple serially connected strings of LED's can be controlled simultaneously via one switch.
