    Abstract: A method and apparatus for producing very high crown and camber curvature in slider materials using a laser processing system which produces fluence which is variable in a controllable manner, by applying a laser beam to the flex side of the slider material and varying the fluence of the laser beam to optimize the curvature in the slider material. The fluence is variable by finely controlling the power output of the laser or by changing the spot size of the laser beam. The beam spot size can be changed by using a focusing lens to establish a focal plane and then varying the relative positions of the slider relative and the focal plane. An apparatus for producing high crown and camber is also disclosed, as well as a slider produced by the process of applying a laser beam to the flex side of the slider material and varying the fluence of the laser beam to optimize the curvature in the slider material.

    Abstract: This invention relates to a method and apparatus for removing surface contamination on a flexible circuit 34 for an inkjet printer cartridge by pulsed laser irradiation in air. The contamination 3 around and inside the tiny inkjet nozzles 4 can be completely removed without any damage on the flexible circuit 34 by the laser irradiation. The cleaning mechanisms are laser-induced ablation of the contamination and fast momentum transferring from the laser beam to the contamination materials. Compared with chemical solution cleaning and plasma etching, this technique has high throughput and does not cause flexible circuit damage, due to the fact that there are no water and chemical solutions involved in the process. Meanwhile, the laser irradiation is only limited in a small area around the tiny inkjet nozzles 4. There is no laser interaction with the thin conductive circuit 34.

    Abstract: A laser machining apparatus capable of effecting a feedback control of a laser output from an early stage of operation and detecting an abnormality of the laser output quickly and precisely. A laser output command issued from a laser output commanding section is subjected to a feedback control and inputted to a laser pumping power supply for a laser oscillator. An output of a laser power sensor is amplified by an amplifier and compared with an output of a measurement simulating section for estimating the measured value of the laser output. A difference of the measured value and the simulated value of the laser output is inputted to the feedback control section and also to an output abnormality detecting section. A measurement input estimating section calculates an average power which should be outputted in a normal condition of the laser machining based on data of the laser output command. A fist order delay system can be adopted as the measurement simulating section. The laser output abnormality detecting section determines whether or not the difference of the measured value and the simulated value is within an allowable range for the detection of an abnormality of the laser machining.

    Abstract: The method for rapid cutting of a workpiece made of brittle material along a predetermined cutting line of any desired shape includes generating laser beams, preferably with a CO or CO2 laser; focusing the laser beams onto the cutting line to form focused laser beams on the cutting line; guiding the focused laser beams one behind the other along the cutting line without melting the brittle material; shaping the respective laser beams so that the respective beam cross-sections forming corresponding focal spots on a surface of the workpiece have predetermined shapes and intensity distributions; moving the workpiece and the laser beams relative to each other along the cutting line so that the focused laser beams induce a thermo-mechanical stress in the brittle material and blowing a fluid cooling medium, such as cold air or an air/water mixture, onto a heated cutting line section of the workpiece for subsequent cooling so as to increase the thermo-mechanical stress in the brittle material above its breaking strength.

    Abstract: A method of welding at least two metal sheets protected by a zinc coating that has a low vaporizing temperature. The metal sheets are placed on top of each other in such a manner that at least one metal sheet has a curved section beginning at the weld area. The weld is performed partly on the metal sheets in contact and partly at the separation between the metal sheets in order to allow gases generated by vaporization of the protective material to escape from the weld area.

    Abstract: A microvalve and a method of forming a diaphragm stop for a microvalve. The microvalve includes a first layer and a diaphragm member to control the flow of fluid through the microvalve. The method comprises the step of forming a contoured shaped recess extending inward from a surface of the layer by using a laser to remove material in a series of areas, at successively greater depths extending inward from said surface. Preferably, the recess has a dome shape, and may be formed by a direct-write laser operated via a computer aided drawing program running on a computer. For example, CAD artwork files, comprising a set of concentric polygons approximating circles, may be generated to create the dome structure. The laser ablation depth can be controlled by modifying the offset step distance of the polygons and equating certain line widths to an equivalent laser tool definition. Preferably, the laser tool definition is combined with the CAD artwork, which defines a laser path such that the resulting geometry has no sharp edges that could cause the diaphragm of the valve to tear or rupture.

    Abstract: This invention refers to a supporting structure (10) for sheet material as sheet metal material (100) cut out by a laser device (200) located above the sheet material and focused on the same, with means of movement between the laser device and the sheet material and/or supporting structure. The supporting structure substantially comprises vertically mounted parallel rows of identical narrow sheet strips (12), each having raised integrated support areas (22) for the sheet material (100) between recessed grooves (20). To increase the life time of the sheet strips and therefore the life of the supporting structure, and at the same time to prevent damage to the underside of the sheet material as sheet metal, needles (24) are set onto the integrated support areas (22) of the sheet strips (12), the free ends of which form points of support (26) for the sheet material (100) laid upon them. The needles (24) consist of material that is substantially more heat-resistant than that of the rest of the supporting structure.

    Abstract: Glazing panels such as vehicle windscreens bonded to a supporting frame are released by firstly arranging light energy delivery means adjacent the panel and subsequently transmitting light energy from the delivery means through the panel thereby to effect release of the panel from the frame. The light may be pulsed according to a predetermined regime and may be delivered by a discharge lamp having rapidly attenuating intensity, or quasi continuous wave pulsed laser. The mechanism of panel release may be by thermal degradation of the bonding material, cleavage of material at a surface of, or within the body of the panel, or a combination of such mechanisms.

    Abstract: A method and apparatus for increasing the effectiveness and efficiency of laser shock processing of a solid material. The method includes applying an energy absorbing coating to a portion of the surface of a solid material, applying an ultraviolet curable resin to the coated portion of the surface of the solid material, applying an ultraviolet light to the curable resin to form a pellicle over the energy absorbing coating on the surface of the solid material, and applying a transparent overlay to the pellicular portion of the solid material. A pulse of coherent laser energy is directed to the coated portion of the solid material to create a shockwave. After the pulse of coherent energy is directed to the solid material, a high-speed jet of fluid may be directed to the coated portion of the solid material to remove the remaining coating from the solid material.
