In a general aspect, a vapor cell includes a body defined by a stack of layers bonded to each other. The stack of layers includes a first end layer disposed at a first end of the body and a second end layer disposed at a second, opposite end of the body. Intermediate layers extend between the first and second end layers and define an internal cavity extending through the body between the first end layer and the second end layer. The stack of layers also includes first and second sets of tabs. The first set of tabs extends outward from the intermediate layers on a first exterior side of the body, and the second set of tabs extends outward from the intermediate layers on a second exterior side of the body. The vapor cell also includes a vapor or a source of the vapor disposed in the internal cavity.

A method of manufacturing a variable reflectance mirror reflective element suitable for use in a vehicular rearview mirror assembly includes providing a front glass sheet and a plurality of rear glass substrates, and joining and spacing the rear glass substrates at the front glass sheet via perimeter seals. After the rear glass substrates are joined with the front glass sheet, the front glass sheet is cut to form a plurality of front glass substrates. A back plate is attached at the rear side of each of the rear glass substrates. After cutting the front glass sheet, the back plate of the respective rear glass substrate and cut front glass substrate portion is fixtured at a finishing tool, which processes the cut edges of at least the respective front glass substrate to provide a finished perimeter edge of the front glass substrate to form a variable reflectance mirror reflective element.

A gas adsorbent is placed on at least a surface of a first plate on one side in a thickness direction thereof or a surface of a second plate on one side in a thickness direction thereof. The gas adsorbent has a shape with relatively raised and lowered parts arranged alternately. The gas adsorbent is placed along a sealant that joins the first and second plates.

A process for the production of a glass-plastic connection which is form-fitting, and to a form-fitting composite between glass and plastic which is obtainable by the process. The process and the glass-plastic composite are characterized in that a glass, which in particular is planar, neither during the process nor in the glass-plastic composite is subjected to a mechanical load which could lead to cracks, e.g. microcracks. Accordingly, in the composite, the glass is connected to a plastic in a stress-free manner The composite of glass with plastic is especially gas-proof and/or liquid-proof.

The invention relates to a process for connecting glass substrates which allows glass substrates to be aligned in a site-specific manner and to subsequently be connected to one another, and to the site-specifically aligned and interconnected glass substrates. Generally, the process relates to connecting glass substrates to one another, optionally also without site-specific alignment. The interconnected glass substrates obtainable by processes according to the invention are characterized by a firm bond with one another, which is preferably formed by solidified glass solder that is in form-fitting engagement with the glass substrates. Therein, recesses, which are preformed in the glass substrate, with glass solder are used for aligning and optionally for connecting the glass substrates.
