  • Patent number: 11471048
    Abstract: This present invention comprises a Galilean tele-microscope lens assembly configured to attach to the front of a binocular indirect ophthalmoscope (BIO) either permanently or by means of a clip or other suitable detachable mechanism, and to enhance an image of a patient's ocular fundus produced by a condensing lens hand-held by the examiner, at their arm's length, in front of the patient's eye. The lens assembly of the present invention magnifies the examiner's view of the hand-held condensing lens itself, and thus magnifies the fundus image produced by the hand-held condensing lens, enabling improved appreciation of finer details in an examination. In addition to improving BIO examinations in general, the present invention is especially advantageous for patients who have disabilities, are wheelchair bound, are children, or are patients of “mission” based ophthalmoscopy services provided in developing, “emerging economy” countries where other examination equipment may not be available.

    Abstract: A method for laser keyhole welding of metal alloys is disclosed. The method independently adjusts power in a focused center beam and power in a concentric focused annular beam. At the termination of a weld, the power in the center beam is initially ramped up and then ramped down, while the power in the annular beam is ramped down.

In the base coat-layer-forming process, a resin-base material of a highly light color at a lightness-level of 70 or more or a clear and colorless resin base-material is formed. In the surface coat-layer forming process, the surface coat-layer of a less-bright color at a lightness-level of 20 or less is formed on the base coat-layer. In the laser-decorating process, the first laser-processed groove penetrating the surface coat-layer and exposing partially the base coat-layer is made by irradiating the infrared laser onto such surface coat-layer, thus providing a fine decoration onto the surface of said decorated-part.

    Abstract: A method of selecting a scanning sequence of a laser beam in a selective laser solidification process, in which one or more objects are formed layer-by-layer by repeatedly depositing a layer of powder on a powder bed and scanning the laser beam over the deposited powder to selectively solidify at least part of the powder layers, includes determining an order in which areas should be scanned by: projecting a debris fallout zone that would be created when solidifying each area based on a gas flow direction of a gas flow passed over the powder bed; determining whether one or more other areas to be solidified fall within the debris fallout zone; and selecting to solidify the one or more other areas that fall within the debris fallout zone before solidifying the area from which the debris fallout zone has been projected.

  • Patent number: 11045902
    Abstract: A linear groove formation method of forming linear grooves in a steel sheet surface using etching can form linear grooves of a uniform shape while suppressing a decrease in magnetic property of a grain-oriented electrical steel sheet caused by laser irradiation for resist removal. A linear groove formation method includes: coating a surface of a grain-oriented electrical steel sheet with a resist; performing a laser scan cyclically in a rolling direction of the grain-oriented electrical steel sheet, the laser scan being applying a laser while scanning the laser in a direction crossing the rolling direction to remove the resist in a portion irradiated with the laser; and etching the grain-oriented electrical steel sheet in each portion in which the resist is removed, to form a linear groove. A coating thickness of the resist is 0.5 ?m to 10 ?m, and a power of the laser is 1500 W or more.

  • Patent number: 11014269
    Abstract: A device for varyingly irradiating by means of ray shaping is described. Furthermore, a method of manufacturing a structure made of a curable material by means of molding is described. In a first step of the method, a molding tool is arranged above a surface such that the curable material abuts on the surface and a molding surface, facing the surface, of the molding tool in a region between the molding tool and the surface and such that further curable material may continue to flow to the region. In a second step, the curable material is irradiated in the region in a locally varying manner such that the ray experiences ray shaping in an optical channel and such that the curable material cures at different speeds in a laterally varying manner.

  • Patent number: 10898970
    Abstract: A profile selector includes at least one beam-forming lens refracting a laser beam to be incident so as to convert a beam profile and emits a laser beam having a beam profile selected from a plurality of beam profiles. A collimating lens converts a laser beam of a divergent beam to be incident into collimated light. A focusing lens focuses the collimated light emitted from the collimating lens and irradiates the focused beam to a sheet metal of a processing target. A moving mechanism moves the collimating lens along an optical axis such that a deviation of a focal point is reduced caused when the beam profile of the focused beam emitted from the focusing lens is selected by the profile selector.
