摘要： A laser welding apparatus and method for easily adjusting a laser focusing position according to a distance from a laser irradiating device to a laser irradiating point on a work piece, or a welding point. A post-collimation laser diameter is measured when the laser emitting end has an optimal laser diameter on the work piece with respect to the distance from the laser processing head to the work piece. Corresponding data is stored with the above distance and the post-collimation laser diameter corresponding to each other. During welding, a diameter of the laser beam passing through a collimate lens is measured by a laser diameter measuring device.

摘要： A cleaning methodology for cleaning a paper path surface upon which paper travels within a printing apparatus. The cleaning device is a flexible substrate sheet having a first side and a second side, with the first side coated preferably in its entirety with an exposed adhesive having a tack strength between about 0.0002 and about 0.12 pound force-square inch. The second side of the substrate sheet can have laminated thereto a foam resin to provide a flexible thickness that assures pressured contact with all paper path surfaces to be cleaned. A lint-free cloth layer can be laminated to the foam resin if present, or the cloth layer can be laminated directly to the second surface of the sheet substrate. Operability occurs as the substrate sheet is fed into the printing apparatus and travels there through along the paper-path surfaces upon which paper is conveyed. Of particular importance is the cleaning of rubber paper-feed rollers within printing equipment and whose surfaces can have accumulated thereupon paper powder, color pigment, dust, ink, toner, etc.

摘要： A focal point controlling section is configured and arranged to control a focal point of the laser beam outputted from a laser oscillator to selectively focus the laser beam on a surface of a workpiece. A laser irradiation position moving section is configured to move a laser irradiation position at which the laser beam strikes on the surface of the workpiece. A control unit is configured to change a heat amount imparted on the surface of the workpiece to switch between a welding state and a non-welding state by controlling at least one of the focal point controlling section and the laser irradiation position moving section while controlling the laser oscillator to continuously output the laser beam before and after switching between the welding state and the non-welding state.

摘要： A laser welding apparatus and method reproduces a welding state substantially identical to an actual operation of a robot at a manufacturing site even when an operating speed of the robot is changed. When a moving speed of the robot is, for example, 50% of an override ratio, a welding point speed, which is a resultant speed of a focus moving speed of the laser beam by movement of the robot having a scanner head and the focus moving speed of the laser beam by rotation of the laser scanning mirror, becomes identical to that when an override ratio is 100%. This is achieved by increasing a rotating speed of a laser scanning mirror within the scanner head.

摘要： A propellant-free composition for lustering and protecting a surface such as a rubber sidewall of a vehicle tire or a vinyl or similar surface. The composition has (1) from about 10 wt. % to 100 wt. % of a high molecular weight liquid linear polysiloxane having a molecular weight above about 550, and (2) from 0 wt. % to about 90 wt. % of a low molecular weight liquid linear and/or cyclic polysiloxane having a molecular weight below about 550. Surface activity of the silicone component of the composition is such that the high molecular weight polysiloxane functions to produce a high luster, while the low molecular weight polysiloxane functions as an evaporative carrier-solvent diluent medium for delivery of the silicone component to the surface and to produce an even distribution on that surface.
