Inventors:

Martin P. Lepselter - Summit NJ 07901

International Classification:

H01J 3730

Appl. No.:

10/249896

Inventors:

Martin Lepselter - Summit NJ, US

International Classification:

H01J017/49

US Classification:

313/582000, 313/584000, 313/586000

Abstract:

An improved plasma display of the type formed on a single side of a first substrate has a substrate with magnetic or ferromagnetic properties and an insulating layer disposed on its surface. As an example, the display can comprise a steel substrate having a porcelain enamel coating. The porcelain enamel forms a thin, hard, transparent and smooth coating on the steel while not disturbing the magnetic properties of the first substrate. The magnetic properties of the first substrate serve to align and affix to the substrate crossing sets of conductors that define picture elements of the display, thus reducing the cost and time associated with accurately aligning the sets of conductors. The porcelain enamel coating prevents short circuits that would otherwise occur between the crossing conductors and the supporting substrate.

Appl. No.:

12/290390

Inventors:

Martin Paul Lepselter - Summit NJ, US

International Classification:

H05B 6/76

US Classification:

219741

Abstract:

This invention relates to a method for producing a low-cost solution to the problem of radiation leakage that escapes from modern microwave ovens due to the door cracks that form in the under-size bezels used in today's microwave oven market. The appliqué structure of the Patent includes a ⅛ inch diameter copper wire that is used to terminate the field lines of any escaping radiation thus preventing leakage beyond the oven itself.

Appl. No.:

8/486745

Inventors:

Martin P. Lepselter - Summit NJ

Assignee:

Spectron Corporation of America, L.L.C. - Summit NJ

International Classification:

H01J 902

US Classification:

445 24

Abstract:

A flat-panel gas discharge display operable with either alternating or direct current is free of implosive forces because it operates at least at substantially atmospheric pressure. The display comprises a first set of conductors disposed on a transparent substrate and a second set crossing over the first set at a distance therefrom. An array of crosspoints is formed at each location where a conductor of the second set crosses over a conductor of the first set. A gas is contained in the space between the first and second sets of conductors at each crosspoint. The gas will undergo light emissive discharge when a voltage greater than or equal to the Paschen minimum firing voltage is applied at a crosspoint. Air may be used as the operative gas. The display is formed on a single substrate, and may be stacked with additional displays in lieu of one or more capping layers.

Abstract:

An SI. sub. 1 I. sub. 2 M (semiconductor-insulator. sub. 1 -insulator. sub. 2 -metal) memory structure, containing an impurity such as tungsten concentrated in a region including the interface ("I. sub. 1 I. sub. 2 ") region between the I. sub. 1 and I. sub. 2 region, is fabricated by depositing an oxide of the impurity, such as tungsten trioxide, on the then exposed, I. sub. 1 layer prior to fabricating the I. sub. 2 layer. The oxide of the impurity, such as tungsten trioxide, can be advantageously deposited by means of reactive evaporation.

Appl. No.:

8/982968

Inventors:

Martin P. Lepselter - Summit NJ

International Classification:

H01J 1749

US Classification:

313586

Abstract:

A flat-panel gas discharge display operable with either alternating or direct current includes magnetic elements within certain of the electrodes which define the discharge cell. The display may be free of implosive forces when operated at least at substantially atmospheric pressure. The display comprises a first set of conductors disposed on a transparent substrate and a second set crossing over the first set at a distance therefrom. The second set of conductors includes a magnetic core or layer whereby the second set of conductors is magnetically attracted to an array of contact points on the substrate. An array of crosspoints is formed at each location where a conductor of the second set crosses over a conductor of the first set. A gas is contained in the space between the first and second sets of conductors at each crosspoint. The gas will undergo light emissive discharge when a voltage greater than or equal to the Paschen minimum firing voltage is applied at a crosspoint.

International Classification:

H01J 1720

US Classification:

313582

Abstract:

A flat-panel gas discharge display operable with either alternating or direct current is free of implosive forces because it operates at substantially atmospheric pressure. The display comprises a first set of conductors disposed on a transparant substrate and a second set of conductors crossing over the first set at a distance therefrom. An array of crosspoints is formed at each location where a conductor of the second set crosses over a conductor of the first set. A gas is contained in the space between the sets of conductors at each crosspoint. The gas will undergo light emissive discharge when a Paschen minimum firing voltage is applied to the pair of crossed conductors crossing at that crosspoint. Air may be used as the operative gas. The display may be formed on a single side of the substrate.
