Transparent material processing with an ultrashort pulse laser

Methods for ultrashort pulse laser processing of optically transparent materials. A method for scribing transparent materials uses ultrashort laser pulses to create multiple scribe features with a single pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with side-illumination and not clearly visible without side-illumination. In addition, a method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. The ultrashort pulse duration causes nonlinear absorption of the laser radiation, and the high repetition rate of the laser causes pulse-to-pulse accumulation of heat within the materials.

Transparent material processing with an ultrashort pulse laser

Methods for ultrashort pulse laser processing of optically transparent materials. A method for scribing transparent materials uses ultrashort laser pulses to create multiple scribe features with a single pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. This enables clean breaking of transparent materials at a higher speed than conventional techniques. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with side-illumination and not clearly visible without side-illumination. In addition, a method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. The ultrashort pulse duration causes nonlinear absorption of the laser radiation, and the high repetition rate of the laser causes pulse-to-pulse accumulation of heat within the materials. The laser is focused near the interface of the materials, generating a high energy fluence at the region to be welded. This minimizes damage to the rest of the material and enables fine weld lines.

Transparent material processing with ultrashort pulse laser

Process for producing display and method of laminating

Provided is a method of bonding a transparent plate or a touch panel to a flat display without allowing air bubbles to form. A fixed amount of liquid adhesive is applied in dots to a bonding surface around corners and at the center. More adhesive is applied to connect the dots of applied adhesive with lines. The bonding surface is then reversed, causing the adhesive to drip, and the dripping adhesive is brought into contact with an opposite bonding surface to fill a gap between the bonding surfaces with the adhesive. The adhesive is cured by irradiation with light incident from a transparent plate side. In short, after dots of adhesive are brought into contact with the opposite bonding surface and the adhesive flows into a pattern that does not let in air bubbles, the gap between the bonding surfaces is filled with the adhesive.

A multiple access fluid transfer device and its method of manufacture

Un dispositif de transfert de fluide (10) comprend un corps fusible (14) possédant un alésage axial (16) et une section transversale généralement constante sur toute la longueur axiale de l'alésage. Une zone d'absorption d'énergie radiante (30) est formée dans le corps. En réaction à l'application d'énergie radiante, la zone fond pour former une ouverture (41) dans le corps qui s'étend radialement dans l'alésage. Un des dispositifs peut être utilisé pour former un joint d'étanchéité amovible pour une source de fluide. Deux dispositifs peuvent être couplés entre eux, leurs zones absorbant l'énergie radiante se trouvant alors en contact face à face. En focalisant l'énergie radiante sur les zones en vis-à-vis, on peut former un cheminement de fluide entre les dispositifs couplés. On peut exécuter des connexions répétées en utilisant la même paire de dispositifs, dont la longueur totale devient de plus en plus courte après chaque connexion, ce qui rend le dispositif plus compact. A fluid transfer device (10) includes a fusible body (14) having an axial bore (16) and a generally constant cross section over the entire axial length of the bore. A region for absorbing radiant energy (30) is formed in the body. In response to the application of radiant energy, the area melts to form an opening (41) in the body which extends radially into the bore. One of the devices can be used to form a removable seal for a source of fluid. Two devices can be coupled together, their zones absorbing radiant energy then being in face-to-face contact. By focusing the radiant energy on the opposite areas, one can form a fluid path between the coupled devices. Repeated connections can be made using the same pair of devices, the overall length of which becomes shorter and shorter after each connection, making the device more compact.

Transparent laminate and process for producing the same

Problems in the technology for producing a transparent laminate utilizing a transparent resin film and problems in the technology for producing a transparent laminate through casting of a resin composition of low viscosity are solved. The transparent laminate is produced by first forming a seal zone for enclosure of a hardening resin composition in a peripheral area on one transparent substratum among a pair of transparent substratums; feeding a hardening resin composition to the region surrounded by the seal zone on the transparent substratum; superimposing the other transparent substratum on the fed hardening resin composition in a vacuum atmosphere so as to interpose the hardening resin composition between the pair of transparent substratums; hermetically sealing them; and hardening the hardening resin composition in a pressure higher that of the atmosphere at the interposition.

Process for producing display and method of laminating

A method for laminating a transparent sheet or touch panel to a flat display while preventing air bubbles from being trapped between these. A liquid adhesive is applied to a bonding surface in spot arrangement in a constant amount so that a liquid-adhesive spot is formed in each of parts around the respective corners of the surface and a central part thereof. The adhesive applied in spot arrangement is spread so as to linearly connect the adhesive spots. This surface is reversed to cause the adhesive to form a sag. This sag is brought into contact with an adherend facing the surface, and the space between the surface and the adherend is filled with the adhesive. The adhesive is cured by irradiation with light from the transparent sheet side. Namely, the adhesive is brought into spot contact and then caused to flow so as to spread into a shape suitable for avoiding air bubble entrapment, before the space is filled with the adhesive.
