The vacuum glass does not comprise an enclosure for enclosing the getter.

An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.

Sealants, vacuum insulated glazing (VIG) units having seals formed from the sealants, and methods for producing the VIG units using the sealants are provided. The sealants include a mixture of glass materials in powder form and a carrier medium.

Methods and vacuum pump heads are provided. The vacuum pump head includes a body having sidewalls and a rear wall, wherein interior surfaces of the sidewalls and the rear wall define a chamber therebetween and distal ends of the sidewalls define an opening to the chamber, a sealing member located at the distal ends of the sidewalls and surrounding the opening defined thereby, the sealing member configured to contact and form a vacuum-tight seal against a surface upon generation of a low-pressure environment within the chamber, a vacuum hose port configured to couple to a vacuum hose of a vacuum pump and to provide a fluidic outlet from the chamber to remove gas from the chamber and thereby generate the low-pressure environment, and an aperture in the body configured to allow a laser beam to be directed therethrough toward the surface while the low-pressure environment is maintained.

A glass panel unit includes a first panel, a second panel, a frame body and a reduced pressure space. The reduced pressure space is surrounded with the first panel, the second panel and the frame body other than an exhaust path capable of exhausting gas to an outside, and sealed in a reduced pressure state. In a state where the inner space has been formed, the seal includes a protruding portion positioned outside of edges of a first surface of a first substrate and a second surface of a second substrate. The protruding portion has a length, along the thickness directions of the first substrate and the second substrate, longer than a prescribed interval.
