  • Patent number: 9751154
    Abstract: 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.

  • Patent number: 9056489
    Abstract: An optical scanning device includes a rotating polygon mirror, a motor, a substrate, a heat releasing member and a heat transfer member. The rotating polygon mirror deflection scans light emitting by a light source. The motor rotatively drives the rotating polygon mirror. The substrate has a drive circuit part for controlling the motor. The heat releasing member releases heat generated from the substrate. The heat transfer member is sandwiched between the substrate and the heat releasing member to be compressively deformed. A receiving portion that part of the heat transfer member compressively deformed enters is formed in a first part of the heat releasing member in which the heat transfer member is provided.

  • Patent number: 9056510
    Abstract: An image forming apparatus A includes: a light irradiation device 3 which irradiates laser light; an image carrying body 1 which is exposed to the laser light to form a latent image on the exposed portion; and an abutting member 31 which is fastened to the light irradiation device in abutting contact with a stationary member F for defining a reference position. The abutting member 31 changes in volume due to temperature fluctuation, and the light irradiation device 3 moves with respect to the stationary member F, in an opposite direction to a focal point shift which has taken place along an irradiation direction of the laser light due to the temperature fluctuation.

  • Patent number: 8987633
    Abstract: A method and apparatus is disclosed for producing precision marks for a metrological scale in the form of a stainless steel ribbon. A laser is used to produce ultra-short pulses which have a fluence at the ribbon such that ablation takes place. The laser light can be scanned via scanner and the pitch of the marks can be controlled. The ablative technique causes little thermal input and improves the accuracy of the scale.

  • Patent number: 8988475
    Abstract: An inkless printing device that comprises a plurality of lasers, a rotating polygonal mirror, and an energy recycling unit. The mirror rotates and reflects a laser beam in a manner that allows the beams to reach any point on the paper. The laser turns ON and OFF while the mirrors are rotating to form a printout. Printing on a sheet of paper is achieved by burning to a certain pre-determined depth of the paper, by using the thermal properties of a laser. The energy recycling unit converts the heat energy generated during the printing process to electrical energy and charges a battery cell. Upon the battery cells being charged to a pre-determined power threshold, the power supply to the printer is changed from the AC supply to the battery supply.
