摘要： A method and apparatus is disclosed for forming lines of weakness in an automotive trim piece so as to enable formation of an airbag deployment opening in the trim piece. A cutting beam, such as a laser is directed at the trim piece surface to be scored and a sensor emits a sensing beam, and a beam combining device receives both the sensor beam and the laser beam and causes downstream beam segments to be collinear with each other as they impinge the trim piece surface. The scoring is thereby able to be carried out in a single pass, and is precise, repeatable and independent of cutting depth, angle of cutting, scoring patterns, material inconsistency, material color, and surface grain variability.

摘要： A laser (126) and an AOM (10) are pulsed at substantially regular and substantially similar constant high repetition rates to provide working laser outputs (40) with variable nonimpingement intervals (50) without sacrificing laser pulse-to-pulse energy stability. When a working laser output (40) is demanded, an RF pulse (38) is applied to the AOM (10) in coincidence with the laser output (24) to transmit it to a target. When no working laser output (40) is demanded, an RF pulse (38) is applied to the AOM (10) in noncoincidence with the laser output (24) so it gets blocked. So the average thermal loading on the AOM (10) remains substantially constant regardless of how randomly the working laser outputs (40) are demanded. The AOM (10) can also be used to control the energy of the working laser output (40) by controlling the power of the RF pulse (38) applied. When the RF power is changed, the RF duration (44) of the RF pulse (38) is modified to maintain the constant average RF power. Consistent loading on the AOM (10) eliminates deterioration of laser beam quality and laser beam pointing accuracy associated with thermal loading variation on the AOM (10) and is advantageous for applications such as IC chip link processing where stable working laser outputs (40) with variable output intervals (50) are needed.

摘要： A method for qualifying airfoil blades includes securing an airfoil blade into a fixture, taking digital measurements of the airfoil blade, comparing the digital measurements of the airfoil blade with measurements of a target model, calculating deviations between the digital measurements of the airfoil blade and the measurements of the target model, determining a required treatment for the airfoil blade to conform with the measurements of the target model, directing a reworking system to provide the required treatment to the airfoil blade, and repeating the previous steps until it is determined that no further treatment is required. An airfoil qualification system for performing the method for qualifying airfoil blades includes a measurement station, a data processing system in communication with the measurement station and for determining a point deviation from a surface standard point for each of at least a portion of the plurality of surface points and for determining a required treatment of the airfoil, and a reworking station for directing treatments to the airfoil in response to input from the data processing system.

摘要： Improved processes for surface treating expanded polytetrafluoroethylene (PTFE) is disclosed and improved surface-treated devices made from the processes. The processes employ a laser to surface-modify an expanded PTFE structure to create a macro-roughened surface that has the capability to remain microporous throughout. The unique process of the present invention creates a ridge and valley structure on the surfaces of devices that includes unique gnarled nodes along valley floors.

摘要： New method of introducing color to two- and three-dimensional images produced in glass or any other transparent media with laser induced micro-explosions, is proposed. The method is based on utilization of a special color film, which consists of multiple periodically repeating transparent stripes of filters of major Red, Green and Blue (RGB) colors. The color film is attached to the glass in front of the image, while external parallel beam of white light illuminates the image through this color film. The image becomes subdivided into multiple color stripes (for two-dimensional image) or slices (for three-dimensional image), which thus transform the image into RGB color sub-pixels. The computer program places the visible dots, resulting from the micro-explosions, into corresponding sub-pixel areas to reproduce the original colors of the image stored in the computer memory. If the sub-pixel pitch is sufficiently short, the human eye perceives the image as a colored one.

摘要： Various laser shock processing methods are provided to establish selective compressive residual stress distribution profiles within a workpiece. An asymmetrical stress distribution profile may be formed through the thickness of a thin section of a gas turbine engine airfoil. One method involves simultaneously irradiating a workpiece with a set of laser beams to form a corresponding set of adjacent non-overlapping laser shock peened surfaces, enabling the shockwaves to encounter one another. Additionally, opposite sides of the workpiece may be irradiated at different times to form opposing laser shock peened surfaces, enabling the shockwaves to meet at a location apart from the mid-plane. Furthermore, opposite sides of the workpiece may be irradiated simultaneously using laser beams having different pulse lengths to form opposing laser shock peened surfaces. Moreover, opposite sides of the workpiece may be irradiated simultaneously to form a set of laterally offset laser shock peened surfaces.

摘要： A gear pump having an inner rotor and an outer rotor is covered by a cylindrical outer casing and side casings. The cylindrical outer casing has two outer circumferential edges which are welded over the entire circumference thereof to the outer edges of the side casings, respectively. The outer casing has two angularly spaced recesses in its inner periphery for receiving slide seals therein. Welding is started at a welding start point which is 90 degrees spaced from the middle point between two recesses. During welding, welding energies are applied to the welding start point and the middle point between two recesses. Those energies tend to deform the casing into oval shapes that are 90 degrees out of phase from each other. Thus, these energies cancel each other, thereby preventing the casing from being deformed.

摘要： For processing electric circuit substrates, a laser source with a diode-pumped. quality-controlled, pulsed solid-state laser is used. The laser is able to emit laser radiation with a wavelength between 266 nm and 1064 nm, a pulse repetition rate between 1 kHz and 1 MHz and a pulse length of 30 ns to 200 ns with an average laser power between 1 W and around 5 W. Pre-specified operating modes can be set via a controller, depending on an area of application, with the appropriate different combinations of laser power and repetition rate. Thus, the same laser can optionally be used to perform a drilling operation, an etch removal operation or an exposure operation. Using a galvo mirror deflector unit that can also be controlled via the deflection unit, the laser beam may be deflected on the substrate in accordance with the relevant operating mode.
