Title: Lamp apparatus with reflective ceramic sleeve holding a plasma that emits light
Inventor: WALKER DALE S
IPC: H01J61/33
Filed: 1997-12-19
Granted: 1999-06-01
Abstract: A lamp apparatus for producing a beam of light that can be used as a part of a source for a projection system. The lamp apparatus of the present invention produces a beam of light originating from a small aperture. The apparatus includes an electrodeless lamp body in the form of elongated outer tube having a hollow interior. An inner sleeve fits or is deposited inside the outer tube, the inner sleeve having a fill containing generally cylindrically or spherical shaped bore. The sleeve provides temperature resistant and reflection properties. Electrodes positioned either internally or externally of the lamp body are provided for producing radio frequency energy that excite the fill contained in the bore of the inner sleeve to form a plasma light source of intense heat. The light thus generated by the plasma in a relatively large volume is constrained to exit through a small aperture at either one, or both, ends of the apparatus.

Inventor: HO CHIH-KUANG
IPC: G11B19/26
Filed: 1998-02-27
Granted: 1999-11-21
Abstract: Method of switching reading modes of CD-ROM between CAV and CLV reading modes, using CLV and CAV position detectors for estimation of current position of the reader for comparison of the preset switching point, for switching of different reading modes and, for calculation of reference frequency required after conversion by means of the position data, making the data transfer rates before and behind the switch point identical, thus preventing unstable system because of discontinued transfer rate of the switch point. In the process of switching modes, reading and transfer of data would be maintained for high data transfer rate, short track seeking time and minimum motor power loss.

Title: Optical device
Inventor: BOZEAT ROBERT JOHN
IPC: H01L31/12
Filed: 1998-03-12
Granted: 2001-07-11
Abstract: An optical device (300) comprises a multilayer structure, formed by wafer bonding, incorporating in sequence a silicon dioxide layer (304), a buried silicide layer (306), a contact layer (308) and a silicon surface layer (310). The surface layer (310) is selectively etched to form an exposed rib (312). An upper surface of the rib (312) is selectively etched to the contact layer (308) in regions remote from the rib (312) to form via channels (316a, 316b) for making electrical connection to the contact layer (308). The rib (312) forms a waveguide along which radiation propagates. When the electrode (314) is biased relative to the contact layer (308), charge carriers are injected into the rib (312) and induce refractive index changes in a central region (324) thereof where most of the radiation propagates along the rib (312). The silicide layer (306) provides an efficient current conduction path for injecting the carriers, thereby providing enhanced device operating bandwidth and reduced power dissipation.

Title: Method for making a nozzle plate for an ink jet printer, nozzle plate for an ink jet printhead, and ink jet printhead
Inventor: KOMPLIN STEVEN ROBERT
IPC: B41J2/135
Filed: 1998-04-01
Granted: 2001-03-11
Abstract: The invention described in the disclosure provides improved methods for making ink jet printer nozzle plates and to nozzle plates made by the method. In the method, a polymeric film having a polymeric layer, an adhesive layer and a protective layer over the adhesive layer is ablated in order to produce flow features comprislng ink flow channels, firing chambers, nozzle holes and an ink supply region. Once the flow features are formed, the protective layer is removed from the polymeric film so that the nozzle plate can be attached to a semiconductor substrate. In the method a portion of the polymeric material in the ink supply region remains substantially unablated in order to reduce the debris produced during the ablations step. By reducing the amount of debris, removal of the protective layer after ablation is enhanced.
