Filed:

Jul 7, 1976

Appl. No.:

5/703382

Inventors:

Kyu C. Park - Yorktown Heights NY
Elizabeth J. Weitzman - Boulder CO

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

B05D 306

US Classification:

427 42

Abstract:

The construction of the dielectric layer of a panel used in making a gas panel display by an E-gun evaporation process in the same evacuated chamber that deposits an electron-emissive layer on the panel so as to obtain increased efficiency in the fabrication and improved operating characteristics of the gas panel. Stress free dielectric layers are obtained by E-gun evaporating borosilicate glass from a molten pool of borosilicate having an area of at least 2cm. sup. 2 up to about 10cm. sup. 2 with the substrate for the layers being maintained at from 200. degree. C to 300. degree. C and the evaporation rate being 40 to 80 A/sec. at approximately 10 inches from the molten pool.

US Classification:

316 21

Abstract:

An in situ process is disclosed for fabricating gas discharge display panels in a sequential seal, bake-out and backfill mode of operation. The single thermal cycle process involves placing unassembled panel parts in a controlled gas ambient furnace system with required seal frame, evacuating said furnace and backfilling with an appropriate ambient atmosphere to an appropriate pressure while heating the furnace. During the heating, the furnace is repeatedly evacuated to moderate vacuum and refilled to some predetermined pressure. The furnace is heated to just above the glass transition temperature of the seal frame in this evacuate-refill mode, then held for some time to achieve outgassing of both panel parts and furnace chamber. Thereafter, the furnace chamber is refilled to one atmosphere and further heated to complete the sealing of the panel. The panel is then cooled to approximately 300. degree.

International Classification:

H01J 902

US Classification:

29 2514

Abstract:

A process for the fabrication of a deformographic storage display tube (DSDT) target in which a wafer of silicon or other etchable material is used (1) as a temporary support during the generation of the active region of the target and (2) as a supporting structure for the completed target. The DSDT target structure comprises a reflection layer on a dielectric layer supported in turn on a silicon or other etchable material wafer, the wafer being etched off at its back side to expose the dielectric layer while providing an outer frame support structure made of the wafer around the edge, with the dielectric layer being etched to form pillars of the dielectric on the backside of the reflection layer, whereby the dielectric pillars enable a deformation action to occur in the region between the pillars. An inner frame support structure comprised of a similarly etched wafer, a dielectric layer and a secondary electron emission layer is fitted against the bottoms of the pillars and bonded to the outer frame support structure, thereby forming the completed target.

Abstract:

An acupressure apparatus includes a tub configured to receive the user's feet for acupressure treatment, an acupressure station having a pair of designated foot placing areas for facilitating accurate positioning of the feet on the acupressure station, a plurality of upward projections formed on an upper surface of the acupressure station, and a plurality of watering holes formed around the projections, and a water supply conduit connected to the bottom wall of the tub for supplying compressed water by operation of a water pump. The watering holes formed in the acupressure station are directed to acupressure points of the feet such that the compressed water delivered through the watering holes provides acupressure stimulations to the acupressure points of the feet.
