A glass panel unit manufacturing method includes disposing a glass adhesive on a first substrate, disposing a second substrate to face the first substrate, forming an inner space between the first substrate and the second substrate, reducing the pressure of the inner space, and forming a reduced-pressure space from the inner space. The glass adhesive includes glass powder having an average particle diameter larger than or equal to 25 m and smaller than or equal to 30 m.

The disclosed embodiments include enclosures for electronic devices formed from RF-transparent, toughened glass materials, such as chemically hardened alkali-aluminosilicate glass. For example, according to the disclosed embodiments, an enclosure for an electronic device may be formed from a plurality of enclosure components joined together along corresponding interfaces to establish an enclosure structure, or alternatively, may be formed from a single enclosure component. In some aspects, the enclosure structure may have corresponding first and second ends, the enclosure structure may have corresponding first and second surfaces, and the second surface may be exposed to an environment. The enclosure may also include first and second cap components disposed at corresponding ones of the first and second ends.

Disclosed herein are sealed devices comprising at least one cavity containing at least one quantum dot or at least one laser diode are also disclosed herein. The sealed devices can comprise a glass substrate sealed to an inorganic substrate, optionally via a sealing layer, the seal extending around the at least one cavity. Display and optical devices comprising such sealed devices are also disclosed herein, as well as methods for making such sealed devices.

Various sapphire and laminate structures are discussed herein. One embodiment may take the form of a sapphire structure having a first sapphire sheet with a first sapphire plane type forming the major surface and a second sapphire sheet having a second different sapphire plane type forming the major surface. The first and second sapphire sheets are fused together to form the sapphire structure.

A synthetic quartz glass lid for use in optical device packages is prepared by furnishing a synthetic quartz glass lid precursor comprising a synthetic quartz glass substrate (1) and a metal or metal compound film (2), and forming a metal base adhesive layer (3) on the metal or metal compound film (2). The metal or metal compound film contains Ag, Bi, and at least one element selected from P, Sb, Sn and In.

Emobidments of a curved glass article are disclosed herein. The curved glass article includes a glass sheet first and second major surfaces. The glass sheet is bent to define a curved region disposed between flat sections. The curved glass article also includes a carrier adhered to the glass sheet. The carrier includes longitudinal strips and lateral strips. The longitudinal strips define the radius of curvature of the curved region. The lateral strips extend between the longitudinal strips. The glass sheet deviates 0.3 mm or less from planar in the flat sections. The longitudinal strips each have a width W.sub.long of 2 mm or less. The first lateral strips each have a width W.sub.lat of 20 mm or less. At least a portion of the width W.sub.lat of each lateral strip is located in the curved region and a flat section.

A method of integrally bonding a glass element to a support element, the method comprising a step of inserting at least one contact element into a contact recess in a surface of the support element. In addition, the method comprises a step of placing the glass element on a portion of the contact element which portion protrudes beyond the surface, and a step of locally heating the contact element in order to connect the glass element to the support element via the contact element. The method also comprises a step of coating at least a part of the contact recess with a separating layer prior to the step of insertion.

An improved optical flow cell adapted for use in a flow cytometer for differentiating formed bodies (e.g., blood cells) in liquid suspensions. Preferably manufactured by assembling, aligning, and optically joining at least two elements made from transparent material, the improved flow cell has a seamless internal flow channel of preferably non-circular cross-section in a cylindrical first element through which prepared samples can be metered and an independent second element having an external envelope suited to acquisition of optical parameters from formed bodies in such suspensions, the second element being conforming and alignable to the first element so that non-axisymmetric refractive effects on optical characterizing parameters of formed bodies passing through the flow channel in the first element may be minimized before the two elements are optically joined and fixed in working spatial relationship. Preferably, such first element is formed by a glass-drawing process in which a relatively large glass preform having a rectilinear internal channel of a desired cross-sectional shape is heated and drawn to achieve a desired cross-sectional area of reduced size. Preferably, such second element is provided by through-boring a suitable commercial optical component to conform to such first element. Also disclosed are preferred methods for differentiating formed bodies using the flow cell of the invention.

A method includes placing a first part proximate a second part, disposing a sintering material in contact with both the first part and the second part, and applying energy to the sintering material to join the first part and the second part. An apparatus includes a first part, a second part, and an additively manufactured joint comprising a sintering material that joins the first part and the second part.
