  • Patent number: 11262668
    Abstract: An image forming apparatus includes a controller. The controller is configured to switch between (i) first speed printing in which a rotation speed of the polygon mirror is a first speed and the power of a laser beam from a first and second laser light sources is a first laser power, and (ii) second speed printing in which the speed of the mirror is slower than the first speed and the power of laser beam from the light sources is a second power weaker than the first power. The controller is configured to control an output timing of the laser beam from the light sources in the second speed printing based on the timings at which the laser beam is detected by first photodetector and second photodetectors when the laser powers of the first laser light source and the second laser light source are changed, respectively.

    Abstract: A method includes transferring multiple discrete components from a first substrate to a second substrate, including illuminating multiple regions on a top surface of a dynamic release layer, the dynamic release layer adhering the multiple discrete components to the first substrate, each of the irradiated regions being aligned with a corresponding one of the discrete components. The illuminating induces a plastic deformation in each of the irradiated regions of the dynamic release layer. The plastic deformation causes at least some of the discrete components to be concurrently released from the first substrate.

  • 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: 9370956
    Abstract: The present invention is directed to a device and a laser, eye-safe method for laser marking slides for use in conjunction with a light microscope. The device is an attachment for a light microscope that allows the operator to make marks on preparations of biological tissues or other materials placed on a glass slide or between a glass slide and a cover slip. The marks can be used to indicate or highlight a microscopic structure or feature of interest. The marking on the slide is performed as the specimen is examined, without having to remove it from the microscope stage. In this way the invention has application in a biomedical or pathology laboratory for diagnostic, research, archival, and teaching or training purposes.

  • Patent number: 9346124
    Abstract: Provided is a method for marking on a pressed metallic component whose visibility and corrosion resistance in a marking target is ensured. The method includes a step of irradiating a base treatment target region including a marking target region with a laser beam on a first irradiation condition, and a step of irradiating the marking target region with the laser beam on a second irradiation condition, in which a charged energy of the laser beam is set to be smaller on the first irradiation condition than the second irradiation condition, thereby providing between the marking pattern and a non-irradiation region, a base region having a residual stress greater than that of the non-irradiation region and a residual stress smaller than that of the marking pattern, so as to ensure a visibility. Furthermore, a corrosion resistance is ensured by using a metallic member which is heat-treated to enhance the hardness.

  • Patent number: 9310711
    Abstract: An image forming apparatus determines a time length of a non-image-forming period in which image formation is not performed, the non-image-forming period being from when image formation on one recording sheet ends to when image formation on the next recording sheet starts, and based on the determined time length, decides the number of times of executing measurement (BD interval measurement) of a generation timing difference between detection signals corresponding to light beams emitted from two light emitting elements. The image forming apparatus executes the decided number of times of BD interval measurement and calculates an average value of the resultant measurement values.
