Patents by Inventor Yoshimitsu ASHIHARA

Yoshimitsu ASHIHARA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12109831
    Abstract: A laser processing device includes a setting device that sets an irradiation condition of laser light, and a first storage that stores the set irradiation condition. The setting device sets different irradiation conditions respectively for cells included in test cells. A verification device captures an image of the processing pattern and calculates luminance values for the cells respectively. The setting device sets at least one of the irradiation conditions for main processing, based on information on luminance values of the test cells extracted from the luminance values for the cells and based on the irradiation conditions set for the test cells.
    Type: Grant

  • Publication number: 20170266758
    Abstract: A laser marker has: a controller configured to oscillate a laser beam; and a head configured to scan a machining surface of a machining target with the laser light. The controller is configured to transmit, to the image processing apparatus, a command for instructing the image processing apparatus to perform a predetermined scene, when the controller is set to cause the image processing apparatus to perform the scene. When the command is received, the image processing apparatus is configured to calculate a deviation amount of the machining target relative to a reference position using image data of an image of the machining target captured by the marker head and to notify the deviation amount to the controller. The controller is configured to correct a position to be scanned with the laser beam based on the deviation amount and then cause the marker head to perform the scanning.
