US Patent:

6635363, Oct 21, 2003
Filed:

Aug 21, 2000
Appl. No.:

09/642901
Inventors:

Steven Jude Duclos - Clifton Park NY
Jon Jansma - Pepper Pike OH
Jacob C. Bortscheller - Clifton Park NY
Robert J. Wojnarowski - Ballston Lake NY
Assignee:

General Electric Company - Schenectady NY
International Classification:

H01L 3300
US Classification:

428690, 428917, 428161, 313512, 313112, 257 95, 257 98, 257100
Abstract:

A light source ( ) includes a light emitting component ( ), such as a UV/blue light emitting diode or laser diode. A layer ( ) of a phosphor material is spaced from the light emitting component by a layer ( ) of a material which is transmissive to the light emitted by the light emitting component. The phosphor material converts a portion of the light emitted by the light emitting component to light of a longer wavelength such as yellow light. In a preferred embodiment, the light transmissive layer valise in thickness over the light emitting component so that the phosphor is spaced further from the diode in regions where the emission is higher. This increases the Surface area of the phosphor in these regions and minimizes the effects of overheating and saturation on the phosphor emission.

Filed:

Aug 7, 2000
Appl. No.:

09/633527
Inventors:

Jacob C. Bortscheller - Clifton Park NY
Robert J. Wojnarowski - Ballston Lake NY
Assignee:

General Electric Company - Schenectady NY
International Classification:

H01J 6304
US Classification:

313512, 313501, 313502, 313498, 257 94, 257 96, 257 97, 257 98, 257 99
Abstract:

A light source ( ) includes a light emitting component ( ), such as a UV/blue light emitting diode or laser diode coated with a layer ( ) of a phosphor material ( ). The phosphor material converts a portion of the light emitted by the light emitting component to light of a longer wavelength, such as yellow light. The thickness d of the layer varies across the light emitting component in relation to the intensity of light emitted by the light emitting component. This maintains a uniform color of the emission from the light source while minimizing the loss in light intensity (brightness) due to the presence of the phosphor.

International Classification:

G01T 120
US Classification:

378 19
Abstract:

A scintillator pack including an x-ray damage shield. The scintillator pack has an array of scintillator pixels. A scintillation light reflecting layer that reflects scintillation light from the pixels is included at least between the scintillator pixels in inter-scintillator regions. An x-ray absorbing layer acts as the x-ray damage shield to protect the portions of the scintillation light reflecting layer from x-rays. The x-ray absorbing layer is formed selectively and in a self aligned manner in regions over the inter-scintillator regions.

Filed:

Oct 5, 1984
Appl. No.:

6/657857
Inventors:

Jacob C. Bortscheller - Ballston Spa NY
Jack D. Kingsley - Schenectady NY
William W. Piper - Scotia NY
Assignee:

General Electric Company - Schenectady NY
International Classification:

H01L 2978
US Classification:

357 237
Abstract:

In a thin film field-effect transistor, source and drain electrodes each include at least one, respective, narrowed, elongated portion. These elongated source and drain portions are oriented in parallel and in adjacent relation to each other, and a respective, complete longitudinal section of each elongated portion overlays a gate electrode. The resulting FET may be fabricated with readily-achievable photolithographic alignment precision as between the source and drain electrode configuration and the gate electrode, and achieves acceptably low source-to-gate and drain-to-gate parasitic capacitances.
