  • Patent number: 11364651
    Abstract: A tool for cutting a substrate and method of use. The tool has a blade with a distal cutting tip at least one shoulder on one side of and proximal the cutting tip. The cutting tip and shoulder are positioned so that when cutting, at least a portion of the at least one shoulder is in contact with at least one cut edge of the substrate defined by a cut line formed by penetrating the substrate thickness with the cutting tip. A heater heats the blade shoulder to a temperature that causes the portion of the shoulder in contact with the cut edge of the substrate to seal the cut edge. The method includes heating the blade, penetrating the substrate with the cutting tip with a portion of the shoulder contacting the substrate, and moving the blade relative to the substrate.

  • Patent number: 9023257
    Abstract: A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

  • Patent number: 8852704
    Abstract: A X-Y plane is a plane parallel to abutting surfaces on which a joining portion is formed, and a Z direction is a direction perpendicular to the X-Y plane. A sealing member is held between the outer circumference side of a guide provided on a lid body and the inner circumference side of a rib provided on a case, and is pressed in a direction parallel to the X-Y plane. Laser light is scanned on the inner circumference side with respect to a ring-shaped pressurization jig with a stopper pressurized by the pressurization jig, so the pressurization jig does not break the path of the laser light. This expands the range of options in the material for the pressurization jig, which enables an easy-maintenance jig to be used, improving productivity.

    Abstract: Some embodiments of the invention provide a method for imprinting fonts on a flexible key cap. In some embodiments, the method for imprinting font on a flexible key cap includes mixing polyurethane (PU) and one or more laser additives to form a PU clay mixture. The PU clay mixture can be infused into a molding tool to form a set of key caps. Some embodiments place a fabric layer over the molding tool and applies pressure over the fabric layer to couple the set of key caps and the fabric layer. A laser marking technique can be applied over a portion of the set of key caps. A characteristic of the portion of the set of key caps can be modified in response to the UV laser application and cause a color change at the portion of the set of key caps.

  • Patent number: 8794033
    Abstract: Certain example embodiments of this invention relate to apparatuses for sealing the tips of pump-out tubes of vacuum insulating glass (VIG) units, and/or associated methods. In certain example embodiments, a laser source used in sealing the pump-out tube is thermally insulated from the VIG unit and emits a laser beam through one or more windows in an oven towards a mirror located therein. The mirror is located so as to redirect the laser beam onto the pump-out tube to thereby seal it. For instance, a substantially horizontal laser beam emitted from a laser source located outside the oven enters into the oven through one or more windows and is reflected by a mirror towards the pump-out tube to be sealed. The repositioning of the laser source advantageously can change its effective focal length and/or the location of the laser beam, e.g., because of the fixed location of the mirror.

    Abstract: An apparatus for forming a pattern using a laser is provided. The apparatus includes a pattern storing unit, a controller, a laser oscillating unit, an X-Y driver, a header unit, and a stage. The pattern storing unit stores data on light guide patterns of a discontinuous straight line shape. The controller transmits position signal of the light guide patterns to the X-Y driver and simultaneously, transmits a switching signal to the laser oscillating unit. The laser oscillating unit outputs a laser beam synchronized with a movement of the header unit. The X-Y driver moves the header unit and the stage. The header unit moves along a first guide rail. The stage moves along a fixed second guide rail in the front and rear direction of the light guide panel.

  • Patent number: RE45403
    Abstract: A modified region 7 to become a starting point region for cutting is formed in a GaAs substrate 12 along a line to cut 5 upon radiation with laser light L which is pulsed laser light. As a consequence, the modified region 7 formed in the GaAs substrate 12 along the line to cut 5 is likely to generate fractures in the thickness direction of an object to be processed 1. Therefore, the modified region 7 having an extremely high function as a starting point region for cutting can be formed in the planar object to be processed 1 comprising the GaAs substrate 12.
