Abstract:
The present invention relates to a method and an apparatus (100) for connecting two substrates (12, 13) by an intermediate body (11) of a heat-activated binder, for example a frit. The binder body is locally heated above its activation temperature, which may preferably be achieved by a laser light beam (L). The subsequent cooling down is done such that, seen in a cross section through the binder body, there is always only a single region (11c) where temperature has already dropped below the curing temperature. Hence it is avoided that local binding between the two substrates occurs at two separate positions between which the substrates are still unconnected.

One of the pair of X beams 130 is connected to the first end 140 and the midpoint 142 of each of the pair of extension bars 56; the other of the pair of X beams 130 is connected to the midpoint 142 and the second end 144 of each of the pair of extension bars 56; and the rotation axis beam 120 is connected to the cross midpoint 134 of each of the pair of X beams 130.
Abstract:
The present invention relates to a laser projection system (1) having means for reducing the coherence of a generated laser beam (3) in order to reduce the occurrence of annoying speckle artefacts in images produced by the system. Coherence is reduced by letting the laser beam (3) pass through a transparent cell (6) comprising first (A) and second (B) immiscible fluids having different refractive indices. The fluids are displaced in the cell, preferably using an electrowetting technique. The cell (6) may thus be realised as an electrowetting lens, which is driven with a pseudo random driving signal.
Abstract:
Method suitable for transferring an electronic component (2''') supported by a carrier (3) to a desired position on a substrate (1). The carrier supporting the component is moved relative to the substrate whilst the component is present on a side of the carrier facing towards the substrate, until the component is positioned opposite the desired position ont eh substrate. Then a light beam (4) is directed at the carrier (3), at the location of the component (2'''), from a side remote from the substrate, as a result of which a connection between the component and the carrier is broken and the component is transferred from the carrier to the substrate.

Abstract:
An electric lamp has a lamp vessel (1) and is provided with an illumination source (2). A central current-supply conductor (3) and a side current-supply conductor (4) issue from the lamp vessel. The electric lamp has a lamp base (5) for providing a mechanical connection of the lamp vessel and for providing a mechanical and electrical connection of the current-supply conductors. At a side facing the lamp vessel, the lamp base is provided with a notch (6) for passing through the side current-supply conductor. At a side facing away from the lamp base, the side current-supply conductor is provided with a coagulated droplet of material of the side current-supply conductor. Preferably, the coagulated droplet is made by laser heating of a portion of the side current-supply conductor issuing from the notch. According to the invention, the side current-supply conductor is reliably connected to the lamp base while soldering is dispensed with.

Abstract:
Disclosed is a method of marking an object by means of a laser beam. Said method comprising the steps of: applying a donor film on a support, said support at least partly being transparent to the laser beam; placing the support with the donor film in proximity to the surface to be patterned, such that the donor film faces the object to be marked; irradiating the donor film with the laser beam through the support, thereby transcribing a pattern of the donor film to the object; and removing the support with the donor film from the object. The donor film has a thickness of at least 0.5 micron. Also disclosed is a marked object that is obtained by means of the above method, wherein the marking has a thickness of at least 0.5 micron.

A MEMS scanner system and method, the system for deflecting an incident laser beam including a MEMS mirror (26) operable to receive the incident laser beam and to generate a reflected laser beam, and an opaque plate 28 having an aperture 30, the opaque plate (28) being opposite the MEMS mirror (26). The aperture (30) is sized to permit the incident laser beam and the reflected laser beam to pass through the aperture (30).
