摘要:
Reflector lamp, particularly metal halogen vapor reflector lamp, comprising a reflector, which is rotationally symmetric about a central axis and which encloses, together with a cover, a lamp interior and which tapers toward a neck region opposite the cover, wherein a burner comprising a burner space and also pinched seals, which lie diametrically opposite each other on opposing sides of the burner space and through which corresponding supply lines are run, is arranged on the central axis in the lamp interior, wherein a tubular shielding enclosure, which is connected to the burner by means of a spring clip, is provided at least partially surrounding the burner.

A multi-functional shroud/arc tube support or clip (40a) for a high intensity discharge lamp (10). The support (40a) has one end (42) formed to engage a shroud (20). The one end (42) is formed as an arcuate member (43). A middle portion (44) is formed of separated, depending legs (46, 48) defining a space (50) therebetween for clasping the substantially rectangular pinch seal (52) of a quartz arc tube (14). The central section (53) is formed to clasp the cylindrical capillary (54) of a ceramic arc tube (14a). The central section (53) comprises the bight of a pair of U-shaped legs and the bights are provided with opposing, substantially hemi-cylindrical concavities (53a).

摘要:
The present invention ensures the hermetic bonding of a support body which is interposed between a face substrate and a back substrate and is formed of a plurality of members thus easily realizing the large-sizing of a screen of a display image and, at the same time, enhancing a hermetic property holding function of the image display device. A support body is interposed between a face substrate and a back substrate while surrounding a display region and hermetically seals both substrates using a sealing material. The support body is formed by hermetically bonding a plurality of support body members each other using a bonding material which has a softening point higher than a softening point of the sealing material.
摘要:
A field emission device having a gate electrode structure in which a nanocrystalline or microcrystalline silicon layer is positioned over a silicon dioxide dielectric layer. Also disclosed are methods for forming the field emission device. The nanocrystalline or microcrystalline silicon layer forms a bond with the dielectric layer that is sufficiently strong to prevent delamination during a chemical-mechanical planarization operation that is conducted during formation of the field emission device. The nanocrystalline or microcrystalline silicon layer is deposited by PECVD in an atmosphere that contains silane and hydrogen at a ratio in a range from about 1:15 to about 1:40. Multiple field emission devices may be formed and included in a flat panel display for computer monitors telecommunications devices, and the like.
摘要:
A field effect electron source includes a grid electrode formed over an insulating layer that covers a cathode electrode formed on an insulating substrate. Holes are provided in the grid electrode-insulating layer structure, the holes extending to the cathode electrode formed on the insulating substrate. Electron emitting microheaps are formed within the holes above the exposed portions of the cathode electrode on the substrate. These microheaps each include at least a macropile of carbon diamond or diamond like carbon powder grains surrounded by the sidewalls of the hole.
摘要:
A flat, cold-cathode electron emitter including a substrate having a relatively flat surface with a low work function electron emission material layer for emitting electrons supported on the surface of the substrate. A contact conductive layer is disposed on the electron emission material layer and defines an aperture therethrough. An insulating layer is disposed on the contact conductive layer and has an aperture defined therethrough coextensive and in peripheral alignment with the aperture in the contact conductive layer and a conductive gate layer is disposed on the insulating layer. The contact conductive layer forms the field potential so that emission occurs substantially in the center of the aperture.
摘要:
An electrical discharge machining electrode for small hole machining. The electrode is of a rod shape and includes a spiral shaped groove extending along the electrode body with a length greater than the thickness of the workpiece. The groove terminates proximate the electrode machining face for receiving a stream of liquid coolant and promoting its flow through the gap during machining. The electrode machining face is blunt and relatively planar in shape.
