Title: Field emission array with shrinking gate opening
Inventor: WANG JR-HUA
IPC: H01J9/02
Filed: 2000-04-26
Granted: 2001-08-01
Abstract: In the well-known technology, the smaller gate opening will make the electron emission density of field emission array higher. However, in order to prevent the tip-to-gate short circuit effect, the minimum diameter of the gate opening in the traditional process can only be about 2 mu m. The present invention provides a two-sectional microtips process to break this lower limit. It differs from the traditional process in that the front process must be stopped before the upper deposition (deposition on the gate surface) has been self-sealed. This front process forms a frustum in the emission cavity instead of a cone. The deposited upper layer forms a hole in the unsealed area, whose diameter is far less than that of the gate opening of the prior art. This upper deposition layer is known as a gate extender. Then, the rear process is executed to form the cone emitter, and the uppermost deposition layer formed at this time is sealed. However, it is necessary to cover an aluminum release layer before performing the rear process on the gate extender, so as to provide a function of removing the uppermost deposition layer on the release layer by the way of selectively etching aluminum to complete the fabrication of field emitter after the rear section cone process is completed.

Filed: 2000-05-29
Granted: 2003-07-11
Abstract: The present invention relates to a combination system consisting of a keyboard and an independent mouse or track ball device using the keyboard as an operation relay structure. In particular, the present invention discloses a type of combination system in which a cable or wireless output mouse or track ball device is coupled with a cable or wireless output keyboard set or, in other words, a cable or wireless output keyboard set is used as the operation relay structure between a cable or wireless transmission mouse or track ball device and a host or receiver. Instead of mechanical combination, the way of the coupling may be cable coupling (when using an electric conductive wire or a light conductor is applied for direct connection or connecting by way of a conductive plug or socket), wireless coupling (when infrared, radio frequency, or ultrasonic is applied), or floating coupling (when mechanical friction rolling displacement or induction displacement exists between the mouse or track ball device and the keyboard set). Thus, the number or length of the required connection wires is minimized while flexibility of independent application remains. Then, not only mess on desktop due to excessive wires but also obstruction and interference between units can be prevented for more proper desktop arrangement and better working environment.

Title: Gas purification system with an integrated hydrogen sorption and filter assembly
Inventor: ARQUIN PIERRE J
IPC: B01D53/04
Filed: 2000-10-11
Granted: 2003-01-21
Abstract: The present invention provides a gas purification system with improved efficiency, simpler construction, cost reductions, form factor improvements, and increased durability. The present invention provides cost and form factor improvements through fewer components over all and through utilizing multiple integrated components. Prior art gas purification systems are more bulky and complicated. The present invention achieves increased thermal efficiency through utilization of a regenerative heat exchanger to recapture a portion of the heat energy transferred to the gas during the purification process. Prior art purifiers lacked a regenerative heat exchanger. The present invention integrates the two components into one integrated heater and purification vessel assembly. The present invention integrates the two discrete components into one integrated hydrogen sorption and particle filter assembly. The integrated hydrogen sorption and particle filter assembly is also capable of operating at higher temperatures. This eases maintenance and manufacture. The resulting gas purification system is simpler through utilizing fewer components, smaller by utilizing fewer and integrated components, and reduced cost through fewer components, smaller components and through reduced manufacture labor requirements.

The VCSEL will then lase at the polarisation which is more predominantly reflected by the grating structure. Alternatively, the upper Bragg mirror has a thickness such that the reflected light of one polarisation destructively interferes with light of said one polarisation which is reflected by the upper Bragg mirror. The VCSEL will then lase at the polarisation which is not preferentially reflected by the grating structure.
