View page
US Patent:
6459198, Oct 1, 2002
Filed:
May 17, 2000
Appl. No.:
09/572157
Inventors:
Kenneth A. Dean - Phoenix AZ
Babu R. Chalamala - Chandler AZ
Dave Uebelhoer - Tempe AZ
Craig Amrine - Tempe AZ
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01J 926
US Classification:
313493, 445 25, 445 41
Abstract:
A method of fabricating a high vacuum display with flat form factor, and the display, include an envelope with two major, parallel spaced apart glass sides and a continuous edge therebetween. An opening is formed through one of the glass sides of the envelope. A plate is provided with an area larger than the opening in the envelope. A button with an area slightly smaller than the opening may be formed on one side of the plate. A low temperature melting material is positioned on the plate around the button and the envelope is positioned in a substantial vacuum. The button is placed in the opening with the plate abutting the glass side outside of the envelope and the low temperature melting material is melted using heat and/or pressure to sealingly engage the button within the opening.

Field Emission Device Having Metal Hydride Hydrogen Source

View page
US Patent:
6633119, Oct 14, 2003
Filed:
May 17, 2000
Appl. No.:
09/572529
Inventors:
Babu R. Chalamala - Chandler AZ
Robert H. Reuss - Fountain Hills AZ
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01J 162
US Classification:
313495, 313309
Abstract:
A field emission display ( ) includes a cathode plate ( ), an anode plate ( ), and a hydrogen source ( ), which is preferably disposed on cathode plate ( ) or anode plate ( ). Hydrogen source ( ) is distributed over the active area of field emission display ( ) and is made from a metal hydride, which is selected from the group consisting of titanium hydride, vanadium hydride, zirconium hydride, hafnium hydride, niobium hydride, and tantalum hydride. The metal hydride can be activated to provide an isotope of hydrogen in situ.

Method For Improving Uniformity Of Emission Current Of A Field Emission Device

View page
US Patent:
6645028, Nov 11, 2003
Filed:
Jun 7, 2000
Appl. No.:
09/589018
Inventors:
Kenneth A. Dean - Phoenix AZ
Babu R. Chalamala - Chandler AZ
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01J 944
US Classification:
445 6
Abstract:
A method for improving uniformity of emission current of a field emission display ( ) includes the step of providing a first carbon nanotube ( ) and a second carbon nanotube ( ), which at least partially define an electron emitter ( ). First carbon nantotube ( ) is characterized by a first emission current capability and second carbon nanotube ( ) is characterized by a second emission current capability, which is less than the first emission current capability. The method further includes the steps of causing first carbon nanotube ( ) to be reduced in length at a first rate and, concurrently, causing second carbon nanotube ( ) to be reduced in length at a second rate, which is less than the first rate and can be equal to zero, thereby reducing the difference between the second emission current capability and the first emission current capability and, thus, improving uniformity of emission current. The selective reductions in length are preferably achieved by performing the step of causing a burn-in current to be emitted by electron emitter ( ).

Digitally Addressed Flat Panel X-Ray Sources

View page
US Patent:
20100189223, Jul 29, 2010
Filed:
Jan 22, 2010
Appl. No.:
12/692496
Inventors:
Mark Eaton - Austin TX, US
Babu Chalamala - Durham NC, US
Mitall More - Austin TX, US
International Classification:
G21K 5/04
H05G 1/30
H05G 2/00
US Classification:
378 68, 378119, 378 91
Abstract:
An apparatus and method for the X-ray irradiation of materials is provided. This apparatus includes an irradiation chamber, a number of flat electromagnetic (X-ray) sources having a number of addressable cathode emitters, a support mechanism, a heat transfer system, a shielding system, and a process controller. A shielded portal within the shielding system allows access to an interior volume of the irradiation chamber. The electromagnetic sources are positioned on or embedded within interior surfaces of the irradiation chamber. These electromagnetic sources generate an electromagnetic flux, such as an X-ray flux, where this flux is used to irradiate the interior volume of the irradiation chamber and any materials placed therein. The operation of the electromagnetic sources and the number of addressable cathode emitters being controlled by the process controller. The materials placed within the interior of the chamber may be supported by a low attenuation support mechanism. This low attenuation support mechanism does not substantially reduce the X-ray flux intended to irradiate the materials placed within the interior volume of the irradiation chamber.

View page
US Patent:
59613629, Oct 5, 1999
Filed:
Sep 9, 1997
Appl. No.:
8/927367
Inventors:
Babu Chalamala - Chandler AZ
Arthur J. Ingle - Chandler AZ
Charles Rowell - Tempe AZ
Thomas L. Credelle - Phoenix AZ
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H01J 938
US Classification:
445 59
Abstract:
A method for in situ cleaning of electron emitters (126, 226, 326, 526) in a field emission device (100, 200, 300, 400, 500) includes the steps of controllably providing hydrogen gas (142, 242, 342, 542) within the field emission device (100, 200, 300, 400, 500) at a time during the operational life of the field emission device (100, 200, 300, 400, 500) and, thereafter, emitting electrons from the electron emitters (126, 226, 326, 526), thereby forming hydrogen free radicals, which decontaminate and condition the emissive surfaces of the electron emitters (126, 226, 326, 526).
